RESUMEN
BACKGROUND: Abdominoplasty is a critical aesthetic and functional procedure for individuals who have undergone massive weight loss. Numerous techniques have been proposed to optimize aesthetic results while minimizing complications. METHODS: This prospective study examined 500 patients who underwent abdominoplasty during body-contouring procedures between 1 January 2018 and 31 December 2021 at a tertiary center. The Skin-Adipose Tissue-Muscle (SAM) protocol was employed to analyze the operative strategies and complication rates and compare them with the existing literature. Furthermore, patient satisfaction and aesthetic outcomes were measured one year post-operation using a comprehensive four-point questionnaire evaluated by the patients themselves and two independent surgeons. RESULTS: Participants had an average age of 34.8 years and a mean BMI of 31.1 kg/m2. The surgeries included 328 full abdominoplasties and 172 T-inverted abdominoplasties. Notable complications included wound infection (4%), wound dehiscence (8.6%), tissue necrosis (0.6%), seroma (8.4%), and hematoma (2.6%). A higher BMI was correlated with an increased risk of complications and lower patient satisfaction. Data analysis was performed using Stata version 18 software. CONCLUSIONS: The increasing prevalence of obesity highlights an urgent need for more bariatric surgeries and subsequent abdominoplasties to mitigate the effects of massive weight loss. A crucial link between elevated BMI and a heightened risk of postoperative complications, emphasizing the necessity for standardized surgical protocols tailored to individuals with higher BMI, was noted. Innovatively, future studies must further investigate the intricate dynamics between BMI and surgical risks. Exploring and establishing uniform, adaptive surgical guidelines promise to revolutionize patient care by significantly reducing complications and enhancing recovery and satisfaction following abdominoplasty.
RESUMEN
There are various models for practicing microsurgical anastomoses, from synthetic to ex vivo and in vivo biological ones. In this study, we present the domestic turkey (Meleagris gallopavo) as an ex vivo biological model in the practice of surgical anastomoses. In our opinion, it represents a model that is very similar to a human one, low cost, and easy to find. In fact, our study shows that the diameters of the arteries and veins used for anastomoses (tibial artery diameter: 2.5â ±â 0.6 mm; tibial vein diameter: 3.5â ±â 1.2 mm) are similar to those of human arteries and veins most frequently used in microsurgical free flaps. So, we believe that this animal model is a great model for microsurgical training for doctors who approach this difficult and long to learn discipline.
RESUMEN
Keloids seem to overexpress cyclo-oxygenase-2 (COX-2), suggesting a role in its deregulated pathway in inducing an altered epithelial-mesenchymal interaction, which may be responsible for the overgrowth of dermal components resulting in scars or keloid lesions. This study aimed to evaluate the effect of Parecoxib, a COX-2 inhibitor, on cell growth in fibroblast primary cultures obtained from human keloid tissues. Tissue explants were obtained from patients who underwent intralesional excision of untreated keloids; central fractions were isolated from keloid tissues and used for establishing distinct primary cultures. Appropriate aliquots of Parecoxib, a COX-2 inhibitor were diluted to obtain the concentration used in the experimental protocols in vitro (1, 10 or 100 µM). Treatment with Parecoxib (at all concentrations) caused a significant decrease in cellular growth from 24 hours onwards, and with a maximum at 72 hours (P < .02). Moreover, at 72 hours Parecoxib significantly reduced cellular vitality. Parecoxib treatment also induced an increase in fragmented nuclei with a maximum effect at 100 µM and a significant decrease in Bcl-2 and an increase in activated caspase-3 protein levels at 72 hours compared with control untreated cultures. Our findings suggest a potential use of the COX-2 inhibitor, Parecoxib, as the therapy for keloids.

RESUMEN
Background: Rhinophyma is a benign condition caused by the excessive growth of sebaceous glands in the nasal tissue, presenting with symptoms such as nasal hypertrophy, erythema, and papules. Cases of basal cell carcinoma in rhinophyma have been reported in literature, but its etiological role remains unclear. It is uncertain whether rhinophyma is predisposed to neoplasm development or if their coexistence is coincidental. Material and Method: We conducted a literature survey to identify such cases reported over the years. Results: We identified 22 studies reporting a total of 47 cases in the literature, all involving male patients. The most common pattern of occurrence was the rapid growth of a nodular formation within the context of rhinophyma. Discussions and Conclusion: The elucidation of the association between basal cell carcinoma and rhinophyma remains challenging. The presence of multiple foci supports the theory that rhinophyma may play a role in their development, but larger studies are needed to establish a causal relationship.

RESUMEN
Background and Objectives: Signs and symptoms of vulvovaginitis, especially when recurrent, have a significant impact on a woman's quality of life. The aim of this study was to survey gynecologists about their habits regarding the treatments of the pathology and to evaluate the efficacy of a novel vaginal hydrogel composed of wheat extracts and polyhexanide aimed at reducing vulvovaginitis symptomatology. Materials and Methods: A cross-sectional analysis of a national survey using 155 Italian gynecologists and a prospective, open-label, observational study were carried out in 75 outpatient clinics across Italy. Pre- and postmenopausal women with suspicion of vulvovaginitis due to at least four of the following symptoms (leucoxanthorrhea, bad odor from genitalia, vulvovaginal dryness, petechiae, burning, and pruritus) while waiting for microbiological swab analysis were included and treated with one hydrogel application every 3 days for 1 week. Primary endpoint was the complete resolution of symptomatology. Results: The pre-study survey reported that, for most clinicians, local or oral treatment (65.7% and 82.8%, respectively) with antibiotics or antifungals is used very often. Therefore, we proceeded to carry out an observational study. Overall, 615 (362 of fertile age and 253 in postmenopause) women were included in this study. At the 28th follow-up examination, complete resolution of symptomatology was achieved in 578/615 (94.1%; p < 0.001) within 12.72 ± 6.55 and 13.22 ± 6.33 days for those of fertile age and in postmenopause, respectively (p = 0.342). All of the evaluated symptoms were significantly reduced after treatment (p = 0.001) without differences according to the patient's menopausal status. A slightly significant reduction in Gardnerella Vaginalis (p = 0.040) and Candida Albicans (p = 0.049) was found after treatment. No patient reported side effects, adverse reactions, or discontinued therapy. Conclusions: This pilot study showed that a hydrogel based on Rigenase® (wheat extract) and polyhexanide could be a promising treatment for the relief of vulvovaginitis symptoms. However, these results are limited by the absence of a control group. Additional comparative and randomized controlled trials between the hydrogel and other non-antibiotic devices as well as local antibiotic therapy should be performed to increase the validity of the findings.

RESUMEN
The use of hyaluronic acid (HA)-based aesthetic therapies is growing steadily, and according to the International Society of Aesthetic Plastic Surgery, more than 4.3 million aesthetic procedures using HA were performed in 2019, an increase of 15.7% than 2018. More people are offering these types of services, often without proper training or qualifications. Therefore, there is an increasing number of reports in the literature relating to possible adverse events, with subsequent therapeutic problems and more or less serious consequences for patients. The aim of this research is to carry out a review of the literature in order to evaluate the impact of hyaluronic acid-based fillers in patients with autoimmune inflammatory diseases, in particular scleroderma and Systemic Lupus Erythematosus (SLE). Although HA plays a central role in the inflammatory process, the use of HA-based fillers in patients with autoimmune inflammatory diseases is still controversial. HA, in fact, in inflamed tissues helps to propagate the inflammatory response and, injected in the form of a dermal filler, could potentially promote reactivation of the underlying disease. For this reason, many specialists do not perform HA-based aesthetic treatments in patients with scleroderma or SLE. However, recent scientific evidence suggests that the use of HA-based fillers in patients with scleroderma can lead to improvement of skin lesions, with satisfactory results. In the literature, there are no clinical studies that contraindicate the administration of HA-based dermal fillers in patients with inflammatory disease.

(1) Background: This narrative review aimed to analyze the epidemiological, clinical, surgical, prognostic, and instrumental aspects of the link between pelvic organ prolapse (POP) and lower urinary tract symptoms (LUTS), collecting the most recent evidence from the scientific literature. (2) Methods: We matched the terms "pelvic organ prolapse" (POP) and "lower urinary tract symptoms" (LUTS) on the following databases: Pubmed, Embase, Scopus, Google scholar, and Cochrane. We excluded case reports, systematic reviews, articles published in a language other than English, and studies focusing only on a surgical technique. (3) Results: There is a link between POP and LUTS. Bladder outlet obstruction (BOO) would increase variation in bladder structure and function, which could lead to an overactive bladder (OAB). There is no connection between the POP stage and LUTS. Prolapse surgery could modify the symptoms of OAB with improvement or healing. Post-surgical predictive factors of non-improvement of OAB or de novo onset include high BMI, neurological pathologies, age > 65 years, and the severity of symptoms; predictors of emptying disorders are neurological pathologies, BOO, perineal dysfunctions, severity of pre-surgery symptoms, and severe anterior prolapse. Urodynamics should be performed on a specific subset of patients (i.e., stress urinary incontinence, correct surgery planning), (4) Conclusions: Correction of prolapse is the primary treatment for detrusor underactivity and for patients with both POP and OAB.

OBJECTIVES: To evaluate the expression of sodium-glucose transporter 2 (SGLT2), inflammatory cytokines, and sirtuins in breast fat tissue at baseline, and serum cytokines of fatty vs. non-fatty pre-menopausal women at baseline, and at 12 months of follow-up. To correlate SGLT2/cytokines/sirtuins expression to clinical variables, and their changes (Δ) at follow-up, as intima-media wall thickness (IMT), left ventricle mass (LVM), left ventricle ejection fraction (LVEF), and myocardial performance index (MPI), and its normalization. BACKGROUND: Pre-menopausal women with the lowest breast fat density (fatty breast) vs. higher breast fat density (non-fatty breast) are a high-risk population for cardiovascular diseases and worse prognosis. METHODS: We analyzed SGLT2/cytokines/sirtuins of excised fatty breasts of fatty vs. non-fatty pre-menopausal women. We correlated SGLT2/cytokines/sirtuins to Δ IMT, Δ LVM, Δ LVEF, and Δ MPI, and normal cardiac performance (NCP) at 1 year of follow-up. RESULTS: fatty vs. non-fatty breast over-expressed SGLT2/inflammatory cytokines, with lowest values of sirtuins (p<0.05). We found a direct correlation between SGLT2 (R2 0.745), TNFα (R2 0.262), and ΔMPI (p<0.05), and an inverse correlation between breast density (R2 -0.198), SIRT-3 (R2-0.181), and ΔMPI (p<0.05). Fatty breast (0.761, CI 95% [0.101-0.915]), SGLT2 (0.812, CI 95% [0.674-0.978]) and SIRT-3 (1.945, CI 95% [1.201-3.148]) predicted NCP at 1 year of follow-up. CONCLUSIONS: fatty vs. non-fatty breast women over-expressed SGLT2/inflammatory cytokines, and down-regulated breast sirtuins. SGLT2/inflammatory cytokines expression and inversely the tissue sirtuin 3 (tSIRT3) and breast percentage density linked to ΔMPI at 1 year of follow-up. Fatty breast and SGLT2 inversely predicted NCP; SIRT-3 increased the probability of NCP at 1 year of follow-up.

Following insults or injury, microglia cells are activated contributing to the cytotoxic response or by promoting an immune-mediated damage resolution. Microglia cells express HCA2R, a hydroxy carboxylic acid (HCA) receptor, which has been shown to mediate neuroprotective and anti-inflammatory effects. In this study we found that HCAR2 expression levels were increased in cultured rat microglia cells after Lipopolysaccharide (LPS) exposure. In a similar fashion, the treatment with MK 1903, a potent full agonist of HCAR2, increased the receptor protein levels. Moreover, HCAR2 stimulation prevented i) cells viability ii) morphological activation iii) pro/anti-inflammatory mediators production in LPS-treated cells. Likewise, HCAR2 stimulation reduced the proinflammatory mediators mRNA expression induced by neuronal chemokine fractalkine (FKN), a neuronal derived chemokine activating its unique receptor, chemokine receptor 1 (CX3CR1) on microglia surface. Interestingly, electrophysiological recordings in vivo revealed that MK1903 was able to prevent the increase of the nociceptive neurons (NS) firing activity mediated by the spinal FKN application in healthy rats. Collectively, our data demonstrate that HCAR2 is functionally expressed in microglia, by showing its capability to shift microglia toward an anti-inflammatory phenotype. Moreover, we indicated the contribute of HCAR2 in the FKN signaling and suggested a possible HCAR2/CX3CR1 functional interaction. This study paves the way for further investigations aimed at understanding the role HCAR2 as potential target in neuroinflammation-based CNS disorders. This article is part of the Special Issue on "The receptor-receptor interaction as a new target for therapy".

BACKGROUND: Vitamin D deficiency has been associated with dry eye development during Sjögren's syndrome (SS). Here, we investigated whether repeated oral vitamin D3 supplementation could prevent the corneal epithelium damage in an SS mouse model. METHODS: 30 female mouse knock-out for the thrombospondin 1 gene were randomized (six per group) in untreated mice euthanized at 6 weeks as negative control (C-) or at 12 weeks as the positive control for dry eye (C+). Other mice were sacrificed after 6 weeks of oral vitamin D3 supplementation in the drinking water (1000, 8000, and 20,000 IU/kg/week, respectively). RESULTS: The C+ mice showed alterations in their corneal epithelial morphologies and thicknesses (p < 0.01 vs. C-), while the mice receiving 8000 (M) and 20,000 (H) IU/kg/week of vitamin D3 showed preservation of the corneal epithelium morphology and thickness (p < 0.01 vs. C+). Moreover, while the C+ mice exhibited high levels and activity of corneal tumor necrosis factor alpha converting enzyme (TACE), neovascularization and fibrosis markers; these were all reduced in the M and H mice. CONCLUSIONS: Oral vitamin D3 supplementation appeared to counteract the negative effect of TACE on corneal epithelium in a mouse model of SS-associated dry eye.
RESUMEN
Background: Diabetic retinopathy (DR) is a neurovascular disease, characterized by a deficiency of brain-derived neurotrophic factor (BDNF), a regulator of autophagy. Beta-hydroxybutyrate (BHB), previously reported as a protective agent in DR, has been associated with BDNF promotion. Here, we investigated whether systemic BHB affects the retinal levels of BDNF and local autophagy in diabetic mice with retinopathy; Methods: C57BL/6J mice were administered with intraperitoneal (i.p.) streptozotocin (STZ) (75 mg/kg) injection to develop diabetes. After 2 weeks, they received i.p. injections of BHB (25−50−100 mg/kg) twice a week for 10 weeks. Retinal samples were collected in order to perform immunofluorescence, Western blotting, and ELISA analysis; Results: BHB 50 mg/kg and 100 mg/kg significantly improved retinal BDNF levels (p < 0.01) in diabetic mice. This improvement was negatively associated with autophagosome−lysosome formations (marked by LC3B and ATG14) and to higher levels of connexin 43 (p < 0.01), a marker of cell integrity. Moreover, BHB administration significantly reduced M1 microglial activation and autophagy (p < 0.01); Conclusions: The systemic administration of BHB in mice with DR improves the retinal levels of BDNF, with the consequent reduction of the abnormal microglial autophagy. This leads to retinal cell safety through connexin 43 restoration.

Pulmonary fibrosis is a consequence of the pathological accumulation of extracellular matrix (ECM), which finally leads to lung scarring. Although the pulmonary fibrogenesis is almost known, the last two years of the COVID-19 pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and its post effects added new particularities which need to be explored. Many questions remain about how pulmonary fibrotic changes occur within the lungs of COVID-19 patients, and whether the changes will persist long term or are capable of resolving. This review brings together existing knowledge on both COVID-19 and pulmonary fibrosis, starting with the main key players in promoting pulmonary fibrosis, such as alveolar and endothelial cells, fibroblasts, lipofibroblasts, and macrophages. Further, we provide an overview of the main molecular mechanisms driving the fibrotic process in connection with Galactin-1, -3, -8, and -9, together with the currently approved and newly proposed clinical therapeutic solutions given for the treatment of fibrosis, based on their inhibition. The work underlines the particular pathways and processes that may be implicated in pulmonary fibrosis pathogenesis post-SARS-CoV-2 viral infection. The recent data suggest that galectin-1, -3, -8, and -9 could become valuable biomarkers for the diagnosis and prognosis of lung fibrosis post-COVID-19 and promising molecular targets for the development of new and original therapeutic tools to treat the disease.

Due to the increased prevalence of obesity in the last decades, bariatric surgery has been on the rise in recent years. Bariatric surgery is a compelling option for weight loss in obese patients with severe obesity-related comorbidities or for whom lifestyle modifications have proven ineffective. Redundant skin following significant weight loss is a common occurrence affecting up to 96% of patients who undergo bariatric surgery, negatively impacting physical and psychosocial health and detracting from activities of daily living. Statistics of the American Society of Plastic Surgeons show that 46,577 body contouring procedures were performed after massive weight loss in the USA in a 2020 report. Abdominoplasty, a well-established cosmetic surgery procedure for improving body contour, is performed by removing excess skin and fat from the abdominal wall and thereby restoring musculofascial integrity and skin elasticity, resulting in a more ideal body shape and increasing quality of life. Although abdominoplasty is a safe procedure, it has been associated with a higher complication rate compared with other body-contouring procedures. Technologic advances over the past decade have been developed as non-invasive alternatives or adjunctive tools to surgery to enhance cosmetic results and minimize complications. New energy-based technologies may supplant invasive surgery for mild to moderate skin laxity and/or diminish the extent of surgery and resulting scars. Plastic surgeons play a significant role in improving the quality of life of patients who suffer from obesity and underwent bariatric surgery. We are deeply convinced, however, that the advancement of knowledge and research in this field will determine the introduction of new technologies and custom-made techniques. This advancement will reduce the complication rate with a rapid reintegration of the patient into the world of work and resumption of daily activities.
RESUMEN
Central post-stroke pain (CPSP) and associated depression remain poorly understood and pharmacological treatments are unsatisfactory. Recently, microglia activation was suggested to be involved in CPSP pathophysiology. The goal of this study was to investigate the effectiveness of a co-ultramicronized combination of N-palmitoylethanolamide and luteolin (PEALut) in a mouse model of thalamic hemorrhage (TH)-induced CPSP. TH was established through the collagenase-IV injection in thalamic ventral-posterolateral-nucleus. PEALut effects in CPSP-associated behaviors were evaluated during a 28-days observation period. We found that repeated administrations of co-ultra PEALut significantly reduced mechanical hypersensitivity after TH, as compared to vehicle, by reducing the early microglial activation in the perilesional site. Moreover, PEALut prevented the development of depressive-like behavior (21 days post-TH). These effects were associated with the restoration of synaptic plasticity in LEC-DG pathway and monoamines levels found impaired in TH mice. Hippocampal MED1 and TrkB expressions were significantly increased in TH compared to sham mice 21 days post-TH, whereas BDNF levels were decreased. PEALut restored MED1/TrkB/BDNF expression in mice. Remarkably, we found significant overexpression of MED1 in the human autoptic brain specimens after stroke, indicating a translational potential of our findings. These results pave the way for better-investigating depression in TH- induced CPSP, together with the involvement of MED1/TrkB/BDNF pathway, proposing PEALut as an adjuvant treatment.
