Abstract
Staphylococcus pseudintermedius (S. pseudintermedius) is a common pathogen that causes canine corneal ulcers. However, the pathogenesis remained unclear. In this study, it has been demonstrated that S. pseudintermedius invaded canine corneal epithelial cells (CCECs) intracellularly, mediating oxidative damage and pyroptosis by promoting the accumulation of intracellular reactive oxygen species (ROS) and activating the NLRP3 inflammasome. The canine corneal stroma was infected with S. pseudintermedius to establish the canine corneal ulcer model in vivo. The intracellular infectious model in CCECs was established in vitro to explore the mechanism of the ROS - NLRP3 signalling pathway during the S. pseudintermedius infection by adding NAC or MCC950. Results showed that the expression of NLRP3 and gasdermin D (GSDMD) proteins increased significantly in the infected corneas (p < 0.01). The intracellular infection of S. pseudintermedius was confirmed by transmission electron microscopy and immunofluorescent 3D imaging. Flow cytometry analysis revealed that ROS and pyroptosis rates increased in the experimental group in contrast to the control group (p < 0.01). Furthermore, NAC or MCC950 inhibited activation of the ROS - NLRP3 signalling pathway and pyroptosis rate significantly, by suppressing pro-IL-1β, cleaved-IL-1β, pro-caspase-1, cleaved-caspase-1, NLRP3, GSDMD, GSDMD-N, and HMGB1 proteins. Thus, the research confirmed that oxidative damage and pyroptosis were involved in the process of CCECs infected with S. pseudintermedius intracellularly by the ROS - NLRP3 signalling pathway. The results enrich the understanding of the mechanisms of canine corneal ulcers and facilitate the development of new medicines and prevention measures.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The reactive oxygen species (ROS) surge in the chronic wound tissue of diabetic ulcers (DUs) aggravates the inflammatory response. The oxidative stress state during inflammation will exacerbate inflammation and cause tissue damage, resulting in prolonged wound healing. Shengjihuayu Formula (SJHYF) is a renowned Chinese medicine prescription for treating chronic wounds in diabetic ulcers. Growing clinical evidence has demonstrated that SJHYF exhibits superior therapeutic efficacy and has a favorable safety profile. However, the underlying mechanisms by which SJHYF ameliorates oxidative damage under pathological conditions of DUs remain unclear. OBJECTIVE To investigate the cytoprotective properties of SJHYF on hydrogen peroxide (H2O2)-induced cell damage in human HaCaT keratinocytes and to explore its potential targets and molecular pathways in treating DUs using RNA-seq. METHODS HaCaT cells were incubated with H2O2 for 24 h to construct an oxidative stress cell model. Cell viability and proliferation were measured using the MTT and EdU assays, respectively. Cell migration was assessed using the scratch assay, and the fluorescence intensity of ROS was measured using the DCFH-DA probe. The chemical components of SJHYF were analyzed by UPLC-Q-TOF/MS, while the therapeutic effects of SJHYF on H2O2-induced HaCaT cells were analyzed using RNA-Seq. The potential target genes were validated using reverse transcription-quantitative polymerase chain reaction (RT-qPCR). At the same time, the pathway phenotype expression of SJHYF on the protection of H2O2-induced HaCaT cells was explored using Western Blot. RESULTS The application of SJHY at a concentration of 0.25 mg/mL promoted cell proliferation, cell migration, and reduced ROS production. In addition, SJHYF was detected to have a total of 93 active compounds, including key components such as Galloyl-beta-D-glucose, Danshensu, Procyanidin B2, Catechin, and Alkannin. The RNA-seq analysis identified several core targets namely KRT17, TGM1, JUNB, PRDX5, TXNIP, PRDX1, HSP90AA1, HSP90AB1, HSPA8, and TNF-α. Western blot revealed the presence of the JNK/c-Jun/MMPs pathway and its related transcription factors. CONCLUSION SJHYF displays significant protective effects on H2O2-induced oxidative cell damage in HaCaT cells via blocking the JNK/c-Jun/MMPs pathway.

Abstract
BACKGROUND Tibial transverse transport (TTT) can promote the healing of chronic foot ulcers, but the specific cellular and molecular mechanisms by which TTT promotes wound healing remain unclear. METHODS New Zealand White rabbits were selected to induce foot ulcer models. The treatment included unilateral TTT surgery and bilateral TTT surgery. Observation of tissue neovascularization structure by HE staining and CD31 immunofluorescence detection. Collagen fiber formation was detected through the Masson staining. The mobilization of endothelial progenitor cell (EPCs) were analyzed by VEGFR2 immunofluorescence detection and flow cytometry detection of the number of VEGFR2/Tie-2-positive cells in peripheral blood. ELISA and qPCR assay were performed to detect VEGFA and CXCL12 levels. RESULTS The complete healing time of ulcer surfaces in sham, unilateral and bilateral TTT groups was about 22 days, 17 days and 13 days, respectively. TTT treatment significantly increased the deposition of granulation tissue and epithelialization of wounds. It also led to an increase in collagen fiber content and the level of the microvascular marker CD31. Furthermore, TTT treatment upregulated the levels of VEGFA and CXCL12 in peripheral blood and wound tissues, as well as increased the expression of VEGFR2 in wound tissues and the proportion of VEGFR2/Tie-2 in peripheral blood. Moreover, these effects of TTT treatment in the bilateral group was more significant than that in the unilateral group. CONCLUSIONS TTT may facilitate wound fibroblasts to release VEGFA and CXCL12, causing EPC mobilization, thus promoting angiogenesis and ulcer wound healing.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Diabetic ulcers represent a chronic condition characterized by prolonged hyperglycemia and delayed wound healing, accompanied by endocrine disorders, inflammatory responses, and microvascular damage in the epidermal tissue, demanding effective clinical treatment approaches. For thousands of years, ancient Chinese ethnopharmacological studies have documented the use of Poria cocos (Schw.) Wolf in treating diabetic ulcers. Recent research has substantiated the diverse pharmacological effects of Poria cocos (Schw.) Wolf, including its potential to alleviate hyperglycemia and exhibit anti-inflammatory, antioxidant, and immune regulatory properties, which could effectively mitigate diabetic ulcer symptoms. Furthermore, being a natural medicine, Poria cocos (Schw.) Wolf has demonstrated promising therapeutic effects and safety in the management of diabetic ulcers, holding significant clinical value. Despite its potential clinical efficacy and applications in diabetic ulcer treatment, the primary active components and underlying pharmacological mechanisms of Poria cocos (Schw.) Wolf remains unclear. Further investigations are imperative to establish a solid foundation for drug development in this domain. AIM OF THE STUDY AND MATERIALS AND METHODS In this study, we aimed to identify the active compounds and potential targets of Poria cocos (Schw.) Wolf using UHPLC-Q-TOF-MS and TCMSP databases. Additionally, we attempt to identify targets related to diabetic ulcers. Following enrichment analysis, a network of protein-protein interactions was constructed to identify hub genes based on the common elements between the two datasets. To gain insights into the binding activities of the hub genes and active ingredients, molecular docking analysis was employed. Furthermore, to further validate the therapeutic effect of Poria cocos (Schw.) Wolf, we exerted in vitro experiments using human umbilical vein vascular endothelial cells and human myeloid leukemia monocytes (THP-1). The active ingredient of Poria cocos (Schw.) Wolf was applied in these experiments. Our investigations included various assays, such as CCK-8, scratch test, immunofluorescence, western blotting, RT-PCR, and flow cytometry, to explore the potential of Poria cocos (Schw.) Wolf triterpenoid extract (PTE) in treating diabetic ulcers. RESULTS The findings here highlighted PTE as the primary active ingredient in Poria cocos (Schw.) Wolf. Utilizing network pharmacology, we identified 74 potential targets associated with diabetic ulcer treatment for Poria cocos (Schw.) Wolf, with five hub genes (JUN, MAPK1, STAT3, AKT1, and CTNNB1). Enrichment analysis revealed the involvement of multiple pathways in the therapeutic process, with the PI3K-AKT signaling pathway showing significant enrichment. Through molecular docking, we discovered that relevant targets within this pathway exhibited strong binding with the active components of Poria cocos (Schw.) Wolf. In vitro experiments unveiled that PTE (10 mg/L) facilitated the migration of human umbilical vein vascular endothelial cells (P < 0.05). PTE also increased the expression of CD31 and VEGF mRNA (P < 0.05) while activating the expressions of p-PI3K and p-AKT (P < 0.05). Moreover, PTE demonstrated its potential by reducing the expression of IL-1β, IL-6, TNF-α, and NF-κB mRNA in THP-1 (P < 0.05) and fostering M2 macrophage polarization. These results signify the potential therapeutic effects of PTE in treating diabetic ulcers, with its beneficial actions mediated through the PI3K-AKT signaling pathway. CONCLUSIONS PTE is the main active ingredient in Poria cocos (Schw.) Wolf that exerts therapeutic effects. Through PI3K-AKT signaling pathway activation and inflammatory response reduction, PTE promotes angiogenesis, thereby healing diabetic ulcers.

Abstract
Chronic stress often triggers gastrointestinal complications, including gastric injury and ulcers. Understanding the role of heat shock protein 27 (HSP27) in stress-induced gastric ulcers could unveil novel therapeutic targets. Here, we established a stress-induced gastric ulcer rat model using water immersion restraint stress and administered adenovirus-packaged HSP27 overexpression vector. Gastric ulcer severity was scored, and mucosal changes were assessed. Gastric epithelial and endothelial cells were treated with lipopolysaccharide and transfected with HSP27 overexpression vectors to evaluate cell viability, migration and angiogenesis. Expression levels of HSP27, C-X-C motif chemokine ligand 12 (CXCL12) and C-X-C motif chemokine receptor 4 (CXCR4) were measured in tissues and cells. HSP27 expression was initially low during stress-induced gastric ulceration but increased during ulcer healing. HSP27 overexpression accelerated ulcer healing in rats, promoting gastric epithelial cell proliferation and migration and gastric endothelial cell angiogenesis through the CXCL12/CXCR4 axis. Inhibitor IT1t reversed the effects of HSP27 overexpression on cell proliferation, migration and angiogenesis. In summary, HSP27 overexpression facilitated ulcer healing, which was partially mediated by the CXCL12/CXCR4 axis.

Abstract
A 52-year-old female presented with labial ulcer of 4-month duration. Examination showed 1 cm × 1 cm single superficial ulcer in the right labium majus. Excision was done, and histopathologic examination revealed surface ulceration and dermal invasion by epithelial neoplasm formed of biphasic proliferation of squamoid and gland-forming cells. Immunohistochemical staining with p63 showed nuclear staining of the squamoid nests and was negative in areas with glandular differentiation, while epithelial membrane antigen and carcinoembryonic antigen highlighted the glandular elements. The case was diagnosed as primary cutaneous adenosquamous carcinoma (ASC). ASC is an uncommon malignant cutaneous neoplasm that is more aggressive than conventional squamous cell carcinoma. There are a few reports of ASC that presented as an erythematous papule or plaque with a preference for the head, neck, or upper extremities. We report a novel case of vulval ASC presented as a superficial ulcer, which is considered a unique site, and its clinical presentation.

Abstract
AIM To compare 1-year outcomes of computed tomography venography (CTV) combined with ultrasound-guided minimally invasive treatment with ascending phlebography and ultrasound-guided treatment for recurrent varicose veins. MATERIALS AND METHODS Consecutive patients with unilateral recurrent varicose veins were matched by gender, age, C classification, and degree of obesity, and randomised in a 1:1 ratio to receive either CTV (CTV group) or ascending phlebography (control group) combined with ultrasound-guided minimally invasive treatment. Patients were followed up by clinical and ultrasound examination. Follow-up was scheduled at 1 week, and 3, 6, and 12 months. The primary outcome measure was the Venous Clinical Severity Score (VCSS) at 12 months. Measures of secondary outcome included Chronic Insufficiency Venous International Questionnaire-20 (CIVIQ-20) score, recurrence of varicose vein or ulcer during 12 months, ulcer healing time, detection and location of treated veins. RESULTS Eighty patients were enrolled. Median VCSS in the CTV group was lower than it in the control group (p=0.04) and the CIVIQ-20 score was higher than the control group (p=0.02). By 12 months, no symptomatically recurrent varicose veins or ulcers had occurred. The ulcer healing time in CTV group was shorter (p<0.01). A greater number of patients had treated veins detected using CTV than by ascending venography (p=0.01), especially among patients with recurrence reflux veins in the groin, perineum, and vulva (p<0.01). CONCLUSION CTV combined with ultrasound may be more helpful than ascending phlebography combined with ultrasound to improve treatment efficacy for recurrent varices. These results should be verified by an future study with more patients and long-term follow-up.

Abstract
BACKGROUND The optimal treatment approach for patients with active venous leg ulcers (VLUs) and post-thrombotic syndrome (PTS) associated with great saphenous vein (GSV) reflux remains unclear. To address this gap, we retrospectively compared the outcomes of patients with post-thrombotic VLU with an intact GSV vs those with a stripped or ablated GSV. METHODS We retrospectively analyzed data from 48 patients with active VLUs and documented PTS, who were treated at a single center between January 2018 and December 2022. Clinical information, including ulcer photographs, was recorded in a prospectively maintained digital database at the initial and follow-up visits. Two patient groups-group A (with an intact GSV) and group B (with a stripped or ablated GSV)-were compared in terms of time to complete healing, proportion of ulcers achieving complete healing, and ulcer recurrence during the follow-up period. RESULTS There were no significant differences in age, gender, initial ulcer size, or ulcer duration between the two groups. All included patients had femoropopliteal post-thrombotic changes. Group A had significantly more completely healed ulcers (33 of 34 ulcers, 97%) compared with group B (10 of 14 ulcers, 71%) (P = .008). Group A also exhibited a significantly shorter time to complete ulcer healing (median: 42.5 days, interquartile range [IQR]: 65) compared with group B (median: 161 days, IQR: 530.5) (P = .0177), with a greater probability of ulcer healing (P = .0084). Long-term follow-up data were available for 45 of 48 patients (93.7%), with a mean duration of 39.6 months (range: 5.7-67.4 months). The proportion of ulcers that failed to heal or recurred during the follow-up period was significantly lower in group A (9 of 32 ulcers, 27%) compared with group B (11 of 13 ulcers, 85%) (P = .0009). In addition, in a subgroup analysis, patients with an intact but refluxing GSV (12 of 34) had a significantly shorter time to heal (median: 34 days, IQR: 57.25) (P = .0242), with a greater probability of ulcer healing (P = .0091) and significantly fewer recurrences (2 of 12, 16%) (P = .006) compared with group B. CONCLUSIONS Our findings suggest that removal of the GSV through stripping or ablation in patients with post-thrombotic deep venous systems affecting the femoropopliteal segment may result in delayed ulcer healing and increased ulcer recurrence. Patients with an intact GSV had better outcomes, even when the refluxing GSV was left untreated. These findings emphasize the potential impact of GSV treatment on the management of VLUs in individuals with PTS. Further investigation is needed to validate these results and explore alternative therapeutic strategies to optimize outcomes for this patient population.

Abstract
Glycogen storage disease type Ib (GSD-Ib) is a rare inborn error of glycogen metabolism caused by mutations in SLC37A4. Patients with GSD-Ib are at high risk of developing inflammatory bowel disease (IBD). We evaluated the efficacy of empagliflozin, a renal sodium‒glucose cotransporter protein 2 (SGLT2) inhibitor, on colonic mucosal healing in patients with GSD-associated IBD. A prospective, single-arm, open-label clinical trial enrolled eight patients with GSD-associated IBD from Guangdong Provincial People's Hospital in China from July 1, 2022 through December 31, 2023. Eight patients were enrolled with a mean age of 10.34 ± 2.61 years. Four male and four female. The endoscopic features included deep and large circular ulcers, inflammatory hyperplasia, obstruction and stenosis. The SES-CD score significantly decreased at week 48 compared with before empagliflozin. Six patients completed 48 weeks of empagliflozin therapy and endoscopy showed significant improvement or healing of mucosal ulcers, inflammatory hyperplasia, stenosis, and obstruction. One patient had severe sweating that required rehydration and developed a urinary tract infection. No serious or life-threatening adverse events. This study suggested that empagliflozin may promote colonic mucosal healing and reduce hyperplasia, stenosis, and obstruction in children with GSD-associated IBD.

Abstract
BACKGROUND Early gastric cancer (EGC) presents a significant challenge in surgical management, particularly concerning postoperative bleeding following endoscopic submucosal dissection. Understanding the risk factors associated with postoperative bleeding is crucial for improving patient outcomes. METHODS Adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a systematic review and meta-analysis were conducted across PubMed, Embase, Web of Science, and the Cochrane Library without publication date restrictions. The inclusion criteria encompassed observational studies and randomized controlled trials focusing on EGC patients undergoing endoscopic submucosal dissection and their risk factors for postoperative bleeding. The Newcastle-Ottawa Scale was utilized for quality assessment. The effect size was calculated using random or fixed-effects models based on the observed heterogeneity. We assessed the heterogeneity between studies and conducted a sensitivity analysis. RESULTS In our meta-analysis, 6 studies involving 4868 EGC cases were analyzed. The risk of postoperative bleeding was notably increased with intraoperative ulcer detection (odds ratio: 1.97, 95% confidence interval [CI]: 1.03-3.76, I2 = 61.0%, P = .025) and antithrombotic medication use (odds ratio: 2.02, 95% CI: 1.16-3.51, I2 = 57.2%, P = .039). Lesion resection size showed a significant mean difference (5.16, 95% CI: 2.97-7.98, P < .01), and longer intraoperative procedure time was associated with increased bleeding risk (mean difference: 11.69 minutes, 95% CI: 1.82-26.20, P < .05). Sensitivity analysis affirmed the robustness of these findings, and publication bias assessment indicated no significant bias. CONCLUSIONS In EGC treatment, the risk of post-endoscopic submucosal dissection bleeding is intricately linked to factors like intraoperative ulcer detection, antithrombotic medication use, the extent of lesion resection, and the length of the surgical procedure. These interwoven risk factors necessitate careful consideration and integrated management strategies to enhance patient outcomes and safety in EGC surgeries.

Abstract
Background Central and bridge nodes can drive significant overall improvements within their respective networks. We aimed to identify them in 16 prevalent chronic diseases during the coronavirus disease 2019 (COVID-19) pandemic to guide effective intervention strategies and appropriate resource allocation for most significant holistic lifestyle and health improvements. Methods We surveyed 16 512 adults from July 2020 to August 2021 in 30 territories. Participants self-reported their medical histories and the perceived impact of COVID-19 on 18 lifestyle factors and 13 health outcomes. For each disease subgroup, we generated lifestyle, health outcome, and bridge networks. Variables with the highest centrality indices in each were identified central or bridge. We validated these networks using nonparametric and case-dropping subset bootstrapping and confirmed central and bridge variables' significantly higher indices through a centrality difference test. Findings Among the 48 networks, 44 were validated (all correlation-stability coefficients >0.25). Six central lifestyle factors were identified: less consumption of snacks (for the chronic disease: anxiety), less sugary drinks (cancer, gastric ulcer, hypertension, insomnia, and pre-diabetes), less smoking tobacco (chronic obstructive pulmonary disease), frequency of exercise (depression and fatty liver disease), duration of exercise (irritable bowel syndrome), and overall amount of exercise (autoimmune disease, diabetes, eczema, heart attack, and high cholesterol). Two central health outcomes emerged: less emotional distress (chronic obstructive pulmonary disease, eczema, fatty liver disease, gastric ulcer, heart attack, high cholesterol, hypertension, insomnia, and pre-diabetes) and quality of life (anxiety, autoimmune disease, cancer, depression, diabetes, and irritable bowel syndrome). Four bridge lifestyles were identified: consumption of fruits and vegetables (diabetes, high cholesterol, hypertension, and insomnia), less duration of sitting (eczema, fatty liver disease, and heart attack), frequency of exercise (autoimmune disease, depression, and heart attack), and overall amount of exercise (anxiety, gastric ulcer, and insomnia). The centrality difference test showed the central and bridge variables had significantly higher centrality indices than others in their networks (P < 0.05). Conclusion To effectively manage chronic diseases during the COVID-19 pandemic, enhanced interventions and optimised resource allocation toward central lifestyle factors, health outcomes, and bridge lifestyles are paramount. The key variables shared across chronic diseases emphasise the importance of coordinated intervention strategies.

Abstract
Smoking may increase the risk of diabetic foot disease and ulceration. It does so by impairing glycaemic control and promoting the formation of advanced glycated end-products. Additionally, smoking is known to delay surgical wound healing and accelerate peripheral arterial disease. We aimed to determine whether toe pressures differed in smokers with a foot ulcer, when compared to non-smokers and ex-smokers, as well as ulcer outcomes at 12 months, among patients attending Blacktown Hospital High Risk Foot Service (HRFS). This study is a retrospective analysis of our prospectively collected clinic database. Eligible participants were adults attending the HRFS between June 2020 and April 2022. Participants were included if they had an ulcer, at least one systolic toe pressure reading completed at their initial visit and attended at least one follow-up visit. Participants were followed until healing, loss to follow-up or a minimum of 12 months. A total of 195 participants were included; 36 smokers, 82 ex-smokers, and 77 controls who had never smoked. Smoking status was by self-report. Current smokers were significantly younger at initial presentation (p = .002) and tended towards lower socioeconomic status (p = .067). Current smokers were significantly more likely to have ischaemic grade 3 toe pressures (< 30 mmHg) of their left foot (p = .027), suggestive of reduced perfusion. At the end of follow up period, smokers had the numerically highest rates of minor amputations. In conclusion, smokers ulcerate younger and are more likely to have grade 3 ischaemia. Collecting information about the brachial artery pressures and the time since the last cigarette may clarify any relationship between smoking and toe pressures.Trial registration: WSLHD HREC ethics approval 2111-02 and ANZCTR registration 382470.

Abstract
BACKGROUND Oral ulcers are a common side effect of chemotherapy and affect patients' quality of life. While stem cell transplantation is a potential treatment for oral ulcers, its efficacy is limited as the stem cells tend to remain in the affected area for a short time. This study aims to develop a treatment for oral ulcers by using trimethyl chitosan (TMC) hydrogel with human tonsil-derived stem cells (hTMSCs) to increase the therapeutic effect of stem cells and investigate their effectiveness. METHODS Animals were divided into four experimental groups: Control, TMC hydrogel, hTMSCs, and hTMSCs loaded in TMC hydrogel (Hydrogel + hTMSCs) (each n = 8). Oral ulcers were chemically induced by anesthetizing the rats followed by injection of dilute acetic acid in the right buccal mucosa. After confirming the presence of oral ulcers in the animals, a single subcutaneous injection of 100 µL of each treatment was applied to the ulcer area. Histological analyses were performed to measure inflammatory cells, oral mucosal thickness, and fibrosis levels. The expression level of inflammatory cytokines was also measured using RT-PCR to gauge therapeutic the effect. RESULTS The ulcer size was significantly reduced in the TMC hydrogel + hTMSCs group compared to the control group. The stem cells in the tissue were only observed until Day 3 in the hTMSCs treated group, while the injected stem cells in the TMC Hydrogel + hTMSCs group were still present until day 7. Cytokine analysis related to the inflammatory response in the tissue confirmed that the TMC Hydrogel + hTMSCs treated group demonstrated superior wound healing compared to other experimental groups. CONCLUSION This study has shown that the adhesion and viability of current stem cell therapies can be resolved by utilizing a hydrogel prepared with TMC and combining it with hTMSCs. The combined treatment can promote rapid healing of oral cavity wounds by enhancing anti-inflammatory effects and expediting wound healing. Therefore, hTMSC loaded in TMC hydrogel was the most effective wound-healing approach among all four treatment groups prolonging stem cell survival. However, further research is necessary to minimize the initial inflammatory response of biomaterials and assess the safety and long-term effects for potential clinical applications.

Abstract
Recently, Enterococcus has been shown to have gastric protective functions, and the mechanisms by which Enterococcus modulates gastric function are still being investigated. Herein, we investigated how Enterococcus faecium (Efm) and E. faecium-derived extracellular vesicles (EVs) (EfmEVs) exert protective effect against ethanol-induced gastric injury by investigating the effect of EfmEVs on gastric mucosal ulcer scoring, histological lesion, mucosal glycoprotein production, acidity, anti-oxidative function, and inflammatory responses in rat. Pretreatment with Efm showed significant reduction of ethanol-induced gastric injury, as evidenced by the lowering of ulcer index, histological lesion, gastric pH, and inflammatory responses and the enhancement of mucosal glycoprotein production and anti-oxidative function. Further functional studies on three bioactive components [inactivated Efm, EfmEVs (EVs), and EV-free supernatants] of the bacterial culture showed that EVs are mostly responsible for the gastroprotective effect. Moreover, EV secretion is beneficial for the gastroprotective effect of Efm. Hence, EVs mediated the protective effect of Efm against ethanol-induced gastric injury by lowering inflammatory responses and enhancing anti-oxidative function and may be a potent anti-inflammatory and anti-oxidative strategy to alleviate hyperinflammatory gastrointestinal tract conditions.IMPORTANCEThis study indicated that Enterococcus faecium provided a protective effect against rat gastric injury, which involved improvement of the mucosal glycoprotein production, anti-oxidative function, and inflammatory responses. Furthermore, we confirmed that three bioactive components (inactivated Efm, extracellular vesicles, and EV-free supernatants) of E. faecium culture also contributed to the gastroprotective effect. Importantly, E. faecium-derived EVs showed an effective impact for the gastroprotective effect.

Abstract
BACKGROUND/AIMS We examined the involvement of cholecystokinin (CCK) in the exacerbation of indomethacin (IND)-induced gastric antral ulcers by gastroparesis caused by atropine or dopamine in mice. METHODS Male mice were fed for 2 h (re-feeding) following a 22-h fast. Indomethacin (IND; 10 mg/kg, s.c.) was administered after re-feeding; gastric lesions were examined 24 h after IND treatment. In another experiment, mice were fed for 2 h after a 22-h fast, after which the stomachs were removed 1.5 h after the end of the feeding period. Antral lesions, the amount of gastric contents, and the gastric luminal bile acids concentration were measured with or without the administration of the pro- and antimotility drugs CCK-octapeptide (CCK-8), atropine, dopamine, SR57227 (5-HT3 receptor agonist), apomorphine, lorglumide (CCK1 receptor antagonist), ondansetron, and haloperidol alone and in combination. RESULTS IND produced severe lesions only in the gastric antrum in re-fed mice. CCK-8, atropine, dopamine, SR57227 and apomorphine administered just after re-feeding increased bile reflux and worsened IND-induced antral lesions. These effects were significantly prevented by pretreatment with lorglumide. Although atropine and dopamine also increased the amount of gastric content, lorglumide had no effect on the delayed gastric emptying provoked by atropine and dopamine. Both ondansetron and haloperidol significantly inhibited the increase of bile reflux and the exacerbation of antral lesions induced by atropine and dopamine, respectively, but did not affect the effects of CCK-8. CONCLUSIONS These results suggest that CCK-CCK1 receptor signal increases bile reflux during gastroparesis induced by atropine and dopamine, exacerbating IND-induced antral ulcers.

Abstract
Chronic diabetic wounds are a serious complication of diabetes and often result in limb amputations and confer high mortality rates. The proinflammatory secretome in the wound perpetuates defective neovascularization and contributes to dysregulated tissue repair. This study aims to design a gelatin methacrylamide (GelMA) hydrogel to sustained the release of grancalcin-neutralizing antibody (GCA-NAb) and evaluate it as a potential scaffold to promote diabetic wound healing. Results show that the expression of grancalcin(GCA), a protein secreted by bone marrow-derived immune cells, is elevated in the wound sites of individuals and animals with diabetic ulcers. Genetic inhibition of grancalcin expression accelerates vascularization and healing in an animal model. Mechanistic studies show that grancalcin binds to transient receptor potential melastatin 8(TRPM8) and partially inactivates its downstream signaling pathways, thereby impairing angiogenesis in vitro and ex vivo. Systemic or topical administration of a GCA-NAb accelerate wound repair in mice with diabetes. The data suggest that GCA is a potential therapeutic target for the treatment of diabetic ulcers.

Abstract
BACKGROUND Chronic refractory ulcers with bone exposure present significant challenges in wound management and necessitate effective treatment strategies to facilitate healing and alleviate patient discomfort. This study aimed to investigate the impact of ultra-pulse carbon dioxide laser on treating chronic refractory ulcers with bone exposure. METHODS This retrospective observational study enrolled patients diagnosed with chronic refractory ulcers with bone exposure admitted to the wound repair clinic of the Affiliated Hospital of Southwest Medical University between July 2018 and July 2019. RESULTS A total of 64 patients with chronic refractory ulcers and bone exposure were included, of which 32 patients underwent ultra-pulse carbon dioxide laser drilling. Compared with patients who did not receive ultra-pulse carbon dioxide laser treatment, those who experienced the procedure demonstrated significantly higher wound healing rates on the fourth, eighth, 12th, 16th, and 20th days after treatment (all P < .001), lower scores on the visual analog scale for pain after 20 days of debridement (0.24 ± 0.05 vs 0.58 ± 0.12, P < .001), lower granulation color observation scores on the 12th, 16th, and 20th days (all P = .001), as well as reduced treatment costs (8200 ± 1600 yuan vs 15400 ± 3800 yuan, P < .001). CONCLUSION Ultra-pulse carbon dioxide laser treatment may enhance the growth of granulation tissue, improve wound healing rates, reduce pain, and lower treatment costs for patients with chronic bone exposure wounds compared to those without such treatment.

Abstract
OBJECTIVE This study compared the efficacies of robotic-assisted stereotactic hematoma drainage and suboccipital craniotomy (SC) in patients with spontaneous cerebellar hemorrhage (SCH). METHODS This retrospective study included 138 non-comatose patients with SCH (Glasgow Coma Scale score [GCS] >8), divided into the SC and Robotic Stereotactic Assistance (ROSA) groups. The study recorded and analyzed complications and prognoses 90 days after ictus. RESULTS The inclusion criteria were met by 138 patients: 61 in the SC and 77 in the ROSA group, with no significant differences in sex, age, GCS score, hematoma volume, and the time from ictus to operation. The time of operation was greater in the SC group (287.53±87.57) than in the ROSA group (60.54±20.03). The evacuation rate (ER) was greater in the SC group (93.20±1.58) than in the ROSA group (89.13±2.75). The incidence of pneumonia and stress ulcers, as well as the length or costs of medical services, were lower in the ROSA group than in the SC group. Ninety days after ictus, the modified Rankin Scale (mRS), Glasgow Prognostic Scale (GOS), and Karnofsky Performance Scale (KPS) scores significantly differed between the groups. The rate of good prognosis in the ROSA group was significantly higher compared with that in the SC group. The incidence of balance disorders was lower in the ROSA group than in the SC group; no statistically significant difference was found in the incidence of dysarthria and swallowing disorders. CONCLUSION Robotic-assisted stereotactic hematoma drainage may be suitable for non-comatose and stable condition patients with SCH. This procedure improves prognosis 90 days after ictus, lowers the incidence of pneumonia and stress ulcers, and reduces the length and costs of medical services.

Abstract
AIM To determine both the risk of first ever ulcer (FEU) and its time to onset in a population which had loss of protective sensation (LOPS) in the foot either with or without loss of protective pain (LOPP). METHODS People with diabetes and LOPS without history of FEU presenting in a specialist clinic were included. LOPP was diagnosed by reduced vibration perception and pain perception by using a pinprick simulator. Participants were followed by routine foot checks, phone interview or by letter until the occurrence of a FEU, death or the end of observation period. Survival functions in LOPP strata were compared by log rank test. The hazard ratio (HR) of an FEU in people with compared to people without LOPP was estimated using Cox regression. Time to first ulcer was estimated using the framework of an accelerated failure time (AFT) model. RESULTS One hundred and thirty participants were followed up for a median of 48.3 months. Pain perception was lost in 55.4%. Eighteen people with LOPP developed a FEU (25.0%) as opposed to six (10.3%) of those with no LOPP (p = 0.02). Age-sex-adjusted HR for FEU was 3.0 (p = 0.02) for people with compared to people without LOPP. Age-sex-adjusted time to FEU for people with LOPP was approximately half (p = 0.03) than people without LOPP. CONCLUSIONS It is suggested that estimation of LOPP is included in routine practice because of its high predictive value for a FEU.

Abstract
BACKGROUND A novel hydrophobically modified chitosan (hm-chitosan) polymer has been previously shown to improve survival in a non-compressible intra-abdominal bleeding model in swine. We performed a 28-day survival study to evaluate the safety of the hm-chitosan polymer in swine. METHODS Female Yorkshire swine (40-50 kg) were used. A mild, non-compressible, closed-cavity bleeding model was created with splenic transection. The hm-chitosan polymer was applied intra-abdominally through an umbilical nozzle in the same composition and dose previously shown to improve survival. Animals were monitored intraoperatively and followed 28 days postoperatively for survival, signs of pain, and end-organ function. Gross pathological and microscopic evaluations were performed at the conclusion of the experiment. RESULTS A total of 10 animals were included (hm-chitosan = 8; control = 2). The 2 control animals survived through 28 days, and 7 of the 8 animals from the hm-chitosan group survived without any adverse events. One animal from the hm-chitosan group required early termination of the study for signs of pain, and superficial colonic ulcers were found on autopsy. Laboratory tests showed no signs of end-organ dysfunction after exposure to hm-chitosan after 28 days. On gross pathological examination, small (<0.5 cm) peritoneal nodules were noticed in the hm-chitosan group, which were consistent with giant-cell foreign body reaction in microscopy, presumably related to polymer remnants. Microscopically, no signs of systemic polymer embolization or thrombosis were noticed. CONCLUSION Prolonged intraperitoneal exposure to the hm-chitosan polymer was tolerated without any adverse event in the majority of animals. In the single animal that required early termination, the material did not appear to be associated with end-organ dysfunction in swine. Superficial colonic ulcers that would require surgical repair were identified in 1 out of 8 animals exposed to hm-chitosan.

Abstract
OBJECTIVE The emerging high-frame-rate vector flow imaging provides a new way of hemodynamic evaluation for complex blood flow. This study was aimed at exploring quantitatively the characteristics of complex flow with turbulence (Tur) index and analyzing flow patterns in atherosclerotic internal carotid artery stenosis (ICAS) using high-frame-rate vector flow imaging. METHODS This study prospectively included 60 patients with ICAS. Tur values in different segments of stenosis and cardiac phases were compared. Spearman correlation analysis was performed between clinical plaque characteristics with turbulence grading by ln(Tur). Three complex flow patterns were qualitatively drawn on vector flow mode, and the rates of detection of flow patterns in different stenosis groups and ulceration groups were compared. RESULTS Highly disordered blood flow was observed in the stenotic (Tur [M, QR] = 12.5%, 21.5%) and distal segment (15.4%, 27.2%), particularly during systole (21.0%, 30.7%, 33.3%, 38.7%, p < 0.05). Spearman correlation analysis revealed that stenosis rate was correlated with turbulence grading in the stenotic (ρ = 0.65, p < 0.05) and distal segment (ρ = 0.79, p < 0.05), and ulcer formation was correlated with turbulence grading in the stenotic segment (ρ = 0.58, p < 0.05). The overall rate of detection of three flow patterns was higher in the severe stenosis group (22/22) versus the mild to moderate stenosis group (21/38) (p < 0.001) and in the ulcer group (21/23) versus the non-ulcer group (23/37) (p < 0.001). CONCLUSION High-frame-rate vector flow imaging was helpful in assessing the severity and characteristics of flow turbulence. Lumen geometric factors could affect flow turbulence and blood flow patterns around the plaque. This would provide important hemodynamic information for the detection of high-risk plaque.

Abstract
Silk fibroin is a fibrillar protein obtained from arthropods such as mulberry and non-mulberry silkworms. Silk fibroin has been used as a dressing in wound treatment for its physical, chemical, mechanical, and biological properties. This systematic review analyzed studies from PubMed, Web of Science, and Scopus databases to identify the molecules preferred for functionalizing silk fibroin-based dressings and to describe their mechanisms of exhibiting anti-inflammatory and antibacterial properties. The analysis of the selected articles allowed us to classify the dressings into different conformations, such as membranes, films, hydrogels, sponges, and bioadhesives. The incorporation of various molecules, including antibiotics, natural products, peptides, nanocomposites, nanoparticles, secondary metabolites, growth factors, and cytokines, has allowed the development of dressings that promote wound healing with antibacterial and immunomodulatory properties. In addition, silk fibroin-based dressings have been established to have the potential to regenerate wounds such as venous ulcers, arterial ulcers, diabetic foot, third-degree burns, and neoplastic ulcers. Evaluation of the efficacy of silk fibroin-based dressings in tissue engineering is an area of great activity that has shown significant advances in recent years.

Abstract
Endoscopic biliary stent insertion has been widely used for the treatment of benign biliary stricture (BBS). Thus, the development of stent materials in the perspectives of structure, mechanical properties, and biocompatibility has been also studied. However, conventional metal and plastic stents have several disadvantages, such as repeated procedures to remove or exchange them, dislodgment, restenosis, biocompatibility, and poor mechanical properties. Sustainable effectiveness, attenuation and prevention of fibrosis, and biocompatibility are key factors for the clinical application of stents to BBS treatment. In addition, loading drugs could show synergistic effects with stents' own performance. We developed a dexamethasone-eluting biodegradable stent (DBS) consisting of a sheath/core structure with outstanding mechanical properties and sustained release of dexamethasone, which maintained its functions in a BBS duct over 12 weeks in a swine model. The insertion of our DBS not only expanded BBS areas but also healed secondary ulcers as a result of the attenuation of fibrosis. After 16 weeks from the insertion, BBS areas were totally improved, and the DBS was degraded and thoroughly disappeared without re-intervention for stent removal. Our DBS would be an effective clinical tool for non-vascular diseases. STATEMENT OF SIGNIFICANCE: This study describes the insertion of a drug-eluting biodegradable stent (DBS) into the bile duct. The sheath/core structure of DBS confers substantial durability and a sustained drug release profile. Drug released from the DBS exhibited anti-fibrotic effects without inflammatory responses in both in vitro and in vivo experiments. The DBS maintained its function over 12 weeks after insertion into the common bile duct, expanding benign biliary stricture (BBS) and reducing inflammation to heal secondary ulcers in a swine BBS model. After 16 weeks from the DBS insertion, the DBS thoroughly disappeared without re-intervention for stent removal, resulting in totally improved BBS areas. Our findings not only spotlight the understanding of the sheath/core structure of the biodegradable stent, but also pave the way for the further application for non-vascular diseases.

Abstract
The term occluding vasculopathies covers a large number of different conditions. These often manifest as skin ulcers. Occluding vasculopathies should be considered in the differential diagnosis of leg ulcers. The term "occlusive vasculopathies" encompasses pathophysiologically related entities that share structural or thrombotic obliteration of small cutaneous vessels. In this article, we will focus on livedoid vasculopathy with and without antiphospholipid syndrome and calciphylaxis with differentiation from hypertonic leg ulcer as the most relevant differential diagnoses of leg ulcer. The term also includes vascular occlusion, for example due to oxalate or cholesterol embolism, and septic vasculopathy. This often leads to acral ulceration and is therefore not a differential diagnosis with classic leg ulcers. It will not be discussed in this article. Occlusive vasculopathy may be suspected in the presence of the typical livedo racemosa or (non-inflammatory) retiform purpura as a sign of reduced cutaneous perfusion in the wound area. Inflammatory dermatoses, especially vasculitides, must be differentiated. This is achieved by histopathological evaluation of a tissue sample of sufficient size and depth taken at the appropriate time. In addition, specific laboratory parameters, particularly coagulation parameters, can support the diagnosis.

Abstract
PURPOSE To compare the efficacy and rapidity of direct microscopic detection of fungal elements from corneal ulcers between 10% potassium hydroxide (KOH) and 1% Chicago Sky Blue 6B (CSB) in 10% KOH (CSB-KOH). METHODS Thirty patients with clinically suspected fungal keratitis were recruited. Participants with impending corneal perforation were excluded. Two slides were smeared with corneal ulcer scrapings from the ulcer's edge and base for comparison of fungal staining solutions. One slide was infused with KOH, and the other slide was filled with CSB-KOH. Additional scraping was collected for inoculation on Sabouraud dextrose agar for fungal culture. The sensitivity, specificity and rapidity of both stainings were analyzed. RESULTS The sensitivity of fungal culture, KOH, and CSB-KOH were 43.75% (95% confidence interval [CI], 19.75%-70.12%), 62.50% (95% CI, 35.43%-84.80%), and 87.50% (95% CI, 61.65%-98.45%), respectively. The specificity were 100% (95% CI, 69.15%-100%) of both stainings and fungal culture which analyzed from 16 fungal keratitis cases by laboratory and clinical diagnosis. Mean CSB-KOH examination time was quicker than KOH with the mean time difference of 5.6 minutes (95% CI, 3.22-7.98 minutes) and p-value < 0.001. CONCLUSIONS CSB-KOH was more effective and faster than KOH in detecting fungal elements from corneal ulcers. Therefore, CSB-KOH may be beneficial in diagnosing fungal keratitis and preventing blindness. Moreover, to the best of our knowledge, this is the first use of CSB stain in fungal keratitis detection.

Abstract
BACKGROUND Perforated marginal ulcers (PMUs) are a rare but known complication of bariatric surgery. Management typically involves prompt surgical intervention, but limited data exists on non-operative approaches. This study reviews published data on non-operative management of PMUs and presents a case series of patients who were managed non-operatively. Our hypothesis is that certain patients with signs of perforation can be successfully managed non-operatively with close observation. METHODS We completed a systematic review searching PubMed, Embase, Web of Science, Cochrane, and clinicaltrials.gov. Ultimately 3 studies described the presentation and non-operative management of 5 patients. Additionally, we prospectively collected data from our institution on all patients who presented between Dec. 2022 and Dec. 2023 with PMUs confirmed on imaging and managed non-operatively. RESULTS In our literature review, three patients had Roux-en-Y gastric bypass (RYGB), while two had one anastomosis gastric bypass. One patient required surgery two days after admission. Another underwent elective conversion surgery weeks later for a non-healing ulcer. Two received endoscopic interventions. One patient recovered with nil-per-os (NPO) status, and intravenous proton pump inhibitor (PPI) treatment. The patients in our case series presented with normal vital signs, an average of 30 months after RYGB, and with CT scan signs of perforation. None of these patients required surgical or endoscopic intervention. CONCLUSION In conclusion, while perforated marginal ulcers have traditionally been considered a surgical emergency, some patients can be successfully treated with non-operative management. More research is needed to identify the clinical presentation features, comorbidities, and imaging findings of this group.

Abstract
ABSTRACT Monkeypox (Mpox) is a zoonotic Orthopoxvirus of the Poxviridae family, endemic to Africa. In August 2022, the US government declared it an emergency because of the worldwide spread. Traditionally, Mpox infection spreads through contact with infected animals. However, the 2022 outbreak Centers for Disease Control and Prevention (CDC) data note that 94% of cases had recent male-to-male sexual or close intimate contact, suggesting a novel sexual transmission. In this article, we report a 39-year-old HIV-positive man presenting with a diffuse cutaneous rash, perianal pain, and bloody stool of 2-week duration. A medical history includes intravenous drug use and multiple sexual partners. Physical examination revealed umbilicated, tan-colored, crusted cutaneous papules scattered across the face, trunk, and genital regions. Perianal lesion biopsy showed an acanthotic epidermis with spongiosis, ballooning degeneration of keratinocytes, and the formation of multinucleated syncytial keratinocytes. A dermal superficial/lichenoid mixed inflammatory cell infiltrate with multinucleated giant cells was noted. Perianal lesion polymerase chain reaction (PCR) was positive for Mpox. Colonoscopy revealed a 3-cm circumferential rectal ulcer with gray exudate and necrosis. A rectal ulcer biopsy showed an ulcerated mucosa with acute proctitis and necrosis. There were scattered macrophages with intranuclear inclusion and glassy vacuolization, and Mpox infection was confirmed by immunostaining with a Mpox-specific anti-Vaccinia virus antibody.

Abstract
OBJECTIVES Although several studies have shown the usefulness of artificial intelligence to identify abnormalities in small-bowel capsule endoscopy (SBCE) images, few studies have proven its actual clinical usefulness. Thus, the aim of this study was to examine whether meaningful findings could be obtained when negative SBCE videos were reanalyzed with a deep convolutional neural network (CNN) model. METHODS Clinical data of patients who received SBCE for suspected small-bowel bleeding at two academic hospitals between February 2018 and July 2020 were retrospectively collected. All SBCE videos read as negative were reanalyzed with the CNN algorithm developed in our previous study. Meaningful findings such as angioectasias and ulcers were finally decided after reviewing CNN-selected images by two gastroenterologists. RESULTS Among 202 SBCE videos, 103 (51.0%) were read as negative by humans. Meaningful findings were detected in 63 (61.2%) of these 103 videos after reanalyzing them with the CNN model. There were 79 red spots or angioectasias in 40 videos and 66 erosions or ulcers in 35 videos. After reanalysis, the diagnosis was changed for 10 (10.3%) patients who had initially negative SBCE results. During a mean follow-up of 16.5 months, rebleeding occurred in 19 (18.4%) patients. The rebleeding rate was 23.6% (13/55) for patients with meaningful findings and 16.1% (5/31) for patients without meaningful findings (P = 0.411). CONCLUSION Our CNN algorithm detected meaningful findings in negative SBCE videos that were missed by humans. The use of deep CNN for SBCE image reading is expected to compensate for human error.

Abstract
We report the case of twins diagnosed with chronic enteropathy associated with the SLCO2A1 gene (CEAS) based on characteristic ulcer findings, which required 8 years to diagnose. Both twins had similar symptoms, including anemia and growth failure but the gastrointestinal tract was not evaluated initially because of mild symptoms that were considered consistent with psychological etiology. The endoscopic findings of the firstborn child showed spiral ulcer scars and pseudodiverticulum formation without Helicobacter pylori infection or eosinophilic infiltration in the duodenum. Since the twins presented with ulcers of an unknown cause simultaneously and the first-born child had a spiral ulcer, CEAS was suspected. Genetic analysis and high levels of prostaglandin E major urinary metabolites in the urine led to a definitive diagnosis of CEAS.

Abstract
OBJECTIVE Several clinical studies have shown that hyaluronic acid collagenase is well-tolerated and very effective in managing chronic venous ulcers. The aim of the present study is to confirm the safety and tolerability of daily application in patients suffering from cutaneous ulcers of different etiologies. The efficacy of the treatment and its impact on patients' quality of life are also assessed. PATIENTS AND METHODS Patients with a clinical diagnosis of skin ulcer with devitalized/fibrinous/slough tissue that could delay the healing process were enrolled in the study. The hyaluronic acid/collagenase ointment was applied topically until wound closure or total debridement of non-viable tissue was achieved, however, with a limit of 30 days. Monitoring was performed weekly, either through outpatient visits or telephone surveys. Assessments included adverse events, local irritation reactions, pain at dressing changes, and wound bed status. Patients were also requested to complete a quality-of-life questionnaire. RESULTS The study involved 96 patients with a mean age of 71 years. The patients suffered mainly from traumatic (21.9%), venous (15.6%), or pressure ulcers (12.5%); in 26% of cases, ulcers had mixed etiology. In approximately 32% of patients, the ulcer had been present for more than 6 months, and 18.1% of subjects had previously undergone surgical wound debridement. CONCLUSIONS Daily application of hyaluronic acid-collagenase achieved the following results: i) absence of adverse events related to the use of the product; ii) significant reduction in the degree of localized irritation and pain at dressing changes; iii) significant support to wound bed preparation; iv) trend towards improvement in the quality of life and health status of the patients.

Abstract
Pressure ulcers including heel ulcers remain a global healthcare concern. This study comprehensively evaluates the biomechanical effectiveness of the market-popular ALLEVYN® LIFE multilayer dressing in preventing heel ulcers. It focuses on the contribution of the frictional sliding occurring between the non-bonded, fully independent layers of this dressing type when the dressing is protecting the body from friction and shear. The layer-on-layer sliding phenomenon, which this dressing design enables, named here the frictional energy absorber effectiveness (FEAE), absorbs approximately 30%-45% of the mechanical energy resulting from the foot weight, friction and shear acting to distort soft tissues in a supine position, thereby reducing the risk of heel ulcers. Introducing the novel theoretical FEAE formulation, new laboratory methods to quantify the FEAE and a review of relevant clinical studies, this research underlines the importance of the FEAE in protecting the heels of at-risk patients. The work builds on a decade of research published by our group in analysing and evaluating dressing designs for pressure ulcer prevention and will be useful for clinicians, manufacturers, regulators and reimbursing bodies in assessing the effectiveness of dressings indicated or considered for prophylactic use.

Abstract
OBJECTIVE This study aimed to assess the frequency with which orthodontic patients decided to shift to another type of orthodontic appliance, among conventional metal brackets, ceramic brackets, lingual brackets and clear aligner, based on their personal experiences of pain, ulcers, bad breath, hygiene issues and social difficulties. MATERIAL AND METHODS This study comprises of patients seeking orthodontic treatment. The sample (n = 500; age group = 19-25 years) was divided equally into four groups based on the treatment modality: conventional metal brackets, ceramic brackets, lingual brackets and clear aligner. Patients rated the questionnaire using a visual analogue scale, to assess variables (such as pain, ulcer etc) that impact various treatment modalities. Subsequently, patients from all groups provided feedback regarding their treatment experiences, and expressed their preference for an alternative modality. Intergroup comparison among the four groups was done using one-way analysis of variance with Tukey's HSD post-hoc test (p ≤ 0.05). RESULTS Patients who received lingual brackets reported higher levels of pain and ulceration, as compared to those who received clear aligners. All four groups showed statistically significant differences for ulcers during treatment (p ≤ 0.05). Of the 125 patients who received conventional metal brackets, 28% expressed a preference for clear aligner therapy, while 20% preferred ceramic brackets. In the lingual group, 56% of 125 patients preferred clear aligner therapy, and 8% preferred ceramic brackets to complete their treatment. In the ceramic group, 83% did not want to switch, whereas 17% desired to switch to clear aligner, while in aligner group no patient desired to switch. CONCLUSIONS A higher percentage of patients from lingual brackets group chose to shift to clear aligners, followed by conventional metal brackets group and by ceramic brackets group, in this descending order. The clear aligner group demonstrated fewer issues than the other treatment modalities.

Abstract
Antimelanoma differentiation-associated protein 5 positive dermatomyositis (MDA5 DM) is a rare subtype of idiopathic inflammatory myopathy. There are limited data available regarding the cutaneous manifestations of MDA5 DM in the African American population. We presented the case of a male patient in his early 20s who presented with debilitating cutaneous ulceration and myopathy. Workup revealed interstitial lung disease (ILD) and positive MDA5 serology consistent with MDA5 DM. He made a remarkable recovery in terms of myopathy and cutaneous ulcerations with a multipronged regimen of prednisone, intravenous immunoglobulin and mycophenolate mofetil. However, there was a progression of ILD on this regimen which warranted use of rituximab.

Abstract
BACKGROUND The diagnosis of primary small intestinal lymphoma (PSIL) is difficult. This study aimed to evaluate the clinical, radiological and endoscopic characteristics of PSIL and provide clue for diagnosis. METHODS A total of 30 patients diagnosed with PSIL who underwent double balloon endoscopy (DBE) in the First Affiliated Hospital of Zhejiang University were retrospectively analyzed. Clinical, radiological and endoscopic data were collected. Univariate analysis was used to determine significant indicators for differentiating three main subtypes of PSIL. Cox regression analysis was performed to assess the risk factors for survival. RESULTS In this study, 10 patients were pathologically diagnosed as diffuse large B-cell lymphoma (DLBCL), 11 were indolent B-cell lymphoma (BCL) and 9 were T-cell lymphoma (TCL). Compared with DLBCL patients, the body mass index (BMI) of TCL patients was significantly lower (p = 0.004). Meanwhile, compared with patients with DLBCL, the patients with indolent BCL had lower levels of C-reactive protein, lactate dehydrogenase (LDH), fibrinogen and D-Dimer (p = 0.004, p = 0.004, p = 0.006, and p = 0.002, respectively), and lower proportion of thicker intestinal wall and aneurysmal dilation in CT scan (p = 0.003 and p = 0.020, respectively). In terms of ulcer morphology, patients with DLBCL had significantly higher proportion of deep ulcers than patients with indolent BCL (p = 0.020, respectively). Cox regression analysis showed that drink (p = 0.034), concomitant colonic ulcers (p = 0.034) and elevated LDH (p = 0.043) are risk factors for mortality in patients with PSIL. CONCLUSIONS This study provides clinical characteristics of patients with PSIL. Thicker intestinal wall and aneurismal dilation detected on CT scan and deeper ulcer on DBE examination helps to establish a diagnosis of DLBCL.

Abstract
BACKGROUND Approximately 10-15% of inflammatory bowel disease (IBD) patients with overlapping features of ulcerative colitis (UC) and Crohn's disease (CD) are termed as inflammatory bowel disease unclassified (IBDU). This study aimed to describe the clinical features of IBDU and evaluate the potential associated factors of reclassification. METHODS The clinical data of 37 IBDU patients were retrospectively analyzed from November 2012 to November 2020. 74 UC and 74 CD patients were randomly selected and age- and sex-matched with the 37 IBDU patients. Clinical characteristics were compared between the three patient groups. Potential factors associated with the IBDU reclassification were evaluated. RESULTS 60% of IBDU patients displayed rectal-sparing disease, and 70% of them displayed segmental disease. In comparison to UC and CD, the IBDU group demonstrated higher rates of gastrointestinal bleeding (32.4%), intestinal perforation (13.5%), spontaneous blood on endoscopy (51.4%), and progression (56.8%). The inflammation proceeded relatively slowly, manifesting as chronic alterations like pseudopolyps (78.4%) and haustra blunt or disappearance (56.8%). 60% of IBDU patients exhibited crypt abscess, and 16.7% of them exhibited fissuring ulcers or transmural lymphoid inflammation. The proportions of IBDU patients receiving immunosuppressants, surgery, and infliximab were basically the same as those of CD patients. During the 79 (66, 91) months of follow-up, 24.3% of IBDU patients were reclassified as UC, while 21.6% were reclassified as CD. The presence of intestinal hemorrhaging was associated with CD reclassification, while hypoalbuminemia was associated with UC reclassification. CONCLUSIONS IBDU may evolve into UC or CD during follow-up, and hemorrhage was associated with CD reclassification. Different from the other two groups, IBDU exhibited a more acute onset and a gradual progression. When an IBD patient presents with transmural inflammation or crypt abscess but lacks transmural lymphoid aggregates or fissuring ulcers, the diagnosis of IBDU should be considered.

Abstract
BACKGROUND Up to 1% of adults will have a leg ulcer at some time. Most leg ulcers are venous in origin and are caused by high pressure in the veins due to blockage or damaged valves. Venous ulcer prevention and treatment typically involves the application of compression bandages/stockings to improve venous return and thus reduce pressure in the legs. Other treatment options involve removing or repairing veins. Most venous ulcers heal with compression therapy, but ulcer recurrence is common. For this reason, clinical guidelines recommend that people continue with compression treatment after their ulcer has healed. This is an update of a Cochrane review first published in 2000 and last updated in 2014. OBJECTIVES To assess the effects of compression (socks, stockings, tights, bandages) for preventing recurrence of venous leg ulcers. SEARCH METHODS In August 2023, we searched the Cochrane Wounds Specialised Register, CENTRAL, MEDLINE, Embase, three other databases, and two ongoing trials registries. We also scanned the reference lists of included studies and relevant reviews and health technology reports. There were no restrictions on language, date of publication, or study setting. SELECTION CRITERIA We included randomised controlled trials (RCTs) that evaluated compression bandages or hosiery for preventing the recurrence of venous ulcers. DATA COLLECTION AND ANALYSIS At least two review authors independently selected studies, assessed risk of bias, and extracted data. Our primary outcome was reulceration (ulcer recurrence anywhere on the treated leg). Our secondary outcomes included duration of reulceration episodes, proportion of follow-up without ulcers, ulceration on the contralateral leg, noncompliance with compression therapy, comfort, and adverse effects. We assessed the certainty of evidence using GRADE methodology. MAIN RESULTS We included eight studies (1995 participants), which were published between 1995 and 2019. The median study sample size was 249 participants. The studies evaluated different classes of compression (UK class 2 or 3 and European (EU) class 1, 2, or 3). Duration of follow-up ranged from six months to 10 years. We downgraded the certainty of the evidence for risk of bias (lack of blinding), imprecision, and indirectness. EU class 3 compression stockings may reduce reulceration compared with no compression over six months (risk ratio (RR) 0.46, 95% confidence interval (CI) 0.27 to 0.76; 1 study, 153 participants; low-certainty evidence). EU class 1 compression stockings compared with EU class 2 compression stockings may have little or no effect on reulceration over 12 months (RR 1.70, 95% CI 0.67 to 4.32; 1 study, 99 participants; low-certainty evidence). There may be little or no difference in rates of noncompliance over 12 months between people using EU class 1 stockings and people using EU class 2 stockings (RR 1.22, 95% CI 0.40 to 3.75; 1 study, 99 participants; low-certainty evidence). UK class 2 hosiery compared with UK class 3 hosiery may be associated with a higher risk of reulceration over 18 months to 10 years (RR 1.55, 95% CI 1.26 to 1.91; 5 studies, 1314 participants; low-certainty evidence). People who use UK class 2 hosiery may be more compliant with compression treatment than people who use UK class 3 hosiery over 18 months to 10 years (RR for noncompliance 0.69, 95% CI 0.49 to 0.99; 5 studies, 1372 participants; low-certainty evidence). There may be little or no difference between Scholl UK class 2 compression stockings and Medi UK class 2 compression stockings in terms of reulceration (RR 0.77, 95% CI 0.47 to 1.28; 1 study, 166 participants; low-certainty evidence) and noncompliance (RR 0.97, 95% CI 0.84.1 to 12; 1 study, 166 participants; low-certainty evidence) over 18 months. No studies compared different lengths of compression (e.g. below-knee versus above-knee), and no studies measured duration of reulceration episodes, ulceration on the contralateral leg, proportion of follow-up without ulcers, comfort, or adverse effects. AUTHORS' CONCLUSIONS Compression with EU class 3 compression stockings may reduce reulceration compared with no compression over six months. Use of EU class 1 compression stockings compared with EU class 2 compression stockings may result in little or no difference in reulceration and noncompliance over 12 months. UK class 3 compression hosiery may reduce reulceration compared with UK class 2 compression hosiery; however, higher compression may lead to lower compliance. There may be little to no difference between Scholl and Medi UK class 2 compression stockings in terms of reulceration and noncompliance. There was no information on duration of reulceration episodes, ulceration on the contralateral leg, proportion of follow-up without ulcers, comfort, or adverse effects. More research is needed to investigate acceptable modes of long-term compression therapy for people at risk of recurrent venous ulceration. Future trials should consider interventions to improve compliance with compression treatment, as higher compression may result in lower rates of reulceration.

Abstract
PURPOSE To evaluate the clinical results of cryopreserved amniotic membrane transplantation as a treatment option for refractory neurotrophic corneal ulcers. METHODS This prospective study included 11 eyes of 11 patients who underwent amniotic membrane transplantation for the treatment of refractory neurotrophic corneal ulcers at Hospital de Clínicas da Universidade Federal do Paraná, in the city of Curitiba, from May 2015 to July 2021. Patients underwent different surgical techniques in which the amniotic membrane was applied with the epithelium facing upward to promote corneal re-epithelialization. RESULTS The median age of the patients was 60 years (range, 34-82 years), and 64% were men. The predominant etiology of corneal ulcers was herpes zoster (45% of cases). Approximately one-third of the patients (27%) were chronically using hypotensive eye drops, and more than half (54%) had previously undergone penetrating corneal transplantation. At the time of amniotic membrane transplantation, 18% of the eyes had corneal melting, 9% had corneal perforation, and the others had corneal ulceration without other associated complications (73%). The time between clinical diagnosis and surgical treatment ranged from 9 days to 2 years. The corrected visual acuity was worse than 20/400 in 90% of the patients preoperatively, with improvement in 36% after 3 months of the procedure, worsening in 18% and remaining stable in 36%. Of the patients, 81% complained of preoperative pain, and 66% of them reported total symptom relief after the surgical procedure. In one month, 54.6% of the patients presented a closure of epithelial defect, and half of the total group evolved with corneal thinning. The failure rate was 45.5% of the cases. CONCLUSION Cryopreserved amniotic membrane transplantation can be considered a good alternative for treating refractory neurotrophic corneal ulcers, as it resulted in significant improvement in pain (66%) and complete epithelial closure (60%) in many patients at 1 month postoperatively. Notably, the high failure rate highlights the need for further studies to identify patientand ulcer-related factors that may influence the outcomes of this procedure.

Abstract
OBJECTIVE In conjunction with appropriate wound care, negative pressure wound therapy with instillation and dwell time (NPWTi-d) may be used as an adjunct therapy for acute or hard-to-heal (chronic) wounds, especially when infected. However, there are very few data on the use of NPWTi-d in the treatment of fibrinous wounds that are difficult to debride mechanically. The main objective of this study was to describe changes in the fibrin area of such wounds, before and after treatment with NPWTi-d. METHOD This was a monocentric, observational, prospective pilot study evaluating the NPWTi-d medical device. Eligible patients included in the study were those with hard-to-heal lower limb ulcers who had previously undergone unsuccessful specific debridement treatment for their wound, with failure of manual mechanic debridement for at least six weeks' duration, and whose wounds had a fibrinous surface area of >70% of the total wound surface area. The primary endpoint was the difference in the percentage of fibrinous surface area before and after treatment. RESULTS A total of 14 patients who received treatment for lower limb ulcers between October 2017 and August 2019 were included in the study. There was a significant shrinkage rate of the fibrinous wound surface between the start and end of treatment (83.6±14.5% and 32.2±19.7%, respectively; p<0.001). CONCLUSION This study showed a significant decrease in fibrin area in wounds treated with NPWTi-d, with good tolerance. We believe that NPWTi-d has its place in the multidisciplinary management of patients with hard-to-heal ulcers. Additional randomised studies are required to confirm these findings.

Abstract
The Torricelli-Bernoulli sign is a rare radiologic sign seen on computed tomography (CT) or magnetic resonance imaging (MRI), which helps direct the diagnosis of a gastrointestinal tumor. It indicates the presence of non-dependent air trapped within a necrotic ulcer located in a gastrointestinal tumor; sometimes, a vertical stream of bubbles emanating from the opening of the ulcer is present. The term Torricelli-Bernoulli sign first appeared in the literature in 1999, referring to the homonymous physical theorems.

Abstract
BACKGROUND The aim of this study was to assess the role of treatment of superficial venous reflux (SVR) in patients with combined deep segmental venous reflux as regards clinical symptoms as well as reflux improvement of the deep veins. METHODS We reviewed 80 patients, retrospectively selected on the inclusion criteria and having combined SVR and segmental deep venous reflux who underwent SVR ablation. The contralateral limb of 44 patients was used as a control group, asked to wear compression stockings for 3 months during day time with no surgical intervention. Duplex ultrasounds follow-up was performed at 3, 6, and 12 months postoperatively. Clinical severity of venous disease was graded from C1 to C6 according to the CEAP (Clinical, Etiology, Anatomy, and Pathophysiology) classification. Duplex ultrasound was done in both supine and standing positions with non-weight-bearing of the examined limb. The venous reflux time, the venous flow volume and the peak venous flow velocity were registered. Removal of SVR was performed using either conventional surgery or radiofrequency ablation. The patient was required to wear compression stockings during the day time for the following weeks. RESULTS During the follow-up period, all patients were improved clinically as regards pain, edema, and ulcer healing. All patients included in this study had no signs of residual SVR. Corrected deep venous segment reflux was in 36 (45%). Similar data at 3, 6, and 12 months postoperatively after SVR removal. The popliteal vein reflux responded less than the femoral vein reflux did. CONCLUSIONS Treatment of the SVR eliminates segmental deep venous reflux in a good percentage of patients regardless of the treatment modality. Also, symptoms improvement and ulcer healing were documented, and hence, more studies are recommended to evaluate this role.

Abstract
Effective exudate management is key for optimal ulcer healing. Superabsorbent dressings are designed to have high fluid handling capacity, reduced risk of exudate leakage, fluid retention under compression, and to sequester harmful exudate components. This study aimed to systematically identify existing evidence for the clinical efficacy and cost-effectiveness of superabsorbent dressings for the treatment of moderate-to-highly exudating chronic ulcers of various etiologies. The aim is focused on examining the 'class' effect of all superabsorbers, not any particular dressing. Clinical and cost effectiveness systematic reviews were conducted, searching Embase, MEDLINE, the Cochrane Library, and the Cumulative Index to Nursing and Allied Health Literature. The Cost Effectiveness Analysis Registry and Econ papers were also searched for the economic review. Outcomes of interest included ulcer closure, dressing properties, hospital- and infection-related outcomes, safety, and economic outcomes. Fourteen studies were included in the clinical systematic review. Eleven were case series, with one randomised controlled trial, one retrospective matched observational study, and one retrospective cohort study. The studies investigated eight superabsorbent dressings and were heterogeneous in their patient population and outcomes. Superabsorbent dressings may result in favourable outcomes, including reductions in frequency of dressing change and pain scores. As most studies were case series, drawing firm conclusions was difficult due to absence of a comparator arm. The economic systematic review identified seven studies, five of which were cost-utility analyses. These suggested superabsorbent dressings are a more cost-effective option for the treatment of chronic ulcers compared with standard dressings. However, the small number and low quality of studies identified in both reviews highlights the need for future research.

Abstract
The management and healing of lower extremity ulcers have always been a complex health problem because the clinical course is typically chronic, the results are often poor, and the socioeconomic impact is considerable. The healing process of foot ulcers of people with diabetes is further hindered by the concomitant presence of obstructive arterial disease, neuropathy, and foot malformation. It is frequently associated with multiresistant infections and often results in micro/macro amputations. Photodynamic therapy employs a photosensitizer activated by light of a specific wavelength able to generate reactive oxygen species, which initiate further oxidative responses locally with components of the bacteria. The experience of the treatment center for the lower extremity ulcers in 17 persons with diabetes in Acerra (Italy) with photoactivated RLP068, reported here, corroborates the results of the clinical trials and of the previous case reports. In all cases, examined photodynamic therapy with photosensitizer RLP068 and red light at 630 nm was found to reduce lesion area and inflammation and to ensure the decrease of bacterial load, hence reducing treatment times and antibiotics use, improving patient outcomes, and reducing the incidence of amputations. The simultaneous combination of photodynamic therapy with other ancillary physical-based treatments such as therapeutic magnetic resonance or Bio-Electro-Magnetic-Energy-Regulation was observed to be safe, time-saving, and able to lead to faster healing.
