Incarceration of a part of the gastric wall into the abdominal cavity in a patient with hiatal hernia and complete dislocation of the stomach (upside-down stomach).

An upside-down stomach is a rare type of hiatal hernia. An 83-year-old woman presented to the emergency room with abdominal pain and vomiting. Computed tomography revealed an upside-down stomach and the incarceration of a part of the gastric body into the abdominal cavity. Upper gastrointestinal endoscopy revealed a circular ulcer caused by gastric ischemia. Although she was discharged after 1 week of conservative therapy, she was readmitted to the hospital 1 day after discharge because of a recurrence of hiatal hernia incarceration. She underwent laparoscopic surgery 4 days after readmission and recovered successfully.

Immunoglobulin G4 -related gastrointestinal disease associated with type 1 autoimmune pancreatitis: A case report.

Immunoglobulin G4 (IgG4)-related diseaseis a systemic inflammatory condition of unknown etiology characterized by increases in serum IgG4 and in the number of IgG4-positive cells in affected tissues. One of the commonly involved locations is the pancreas; this condition is known as type 1 autoimmune pancreatitis (AIP). Type 1 AIP, which shows a biliary stricture in the intrapancreatic bile duct, can be misdiagnosed as a malignancy due to similar cholangiography findings and clinical presentation. In rare cases complicated by post-bulbar duodenal ulcers, differentiating between type 1 AIP and malignancies is even more difficult. An 81-year-old male was referred to our hospital for the treatment of a pancreatic head mass and obstructive jaundice. Serological and radiological findings were consistent with both type 1 AIP and a malignancy. Gastroduodenoscopy revealed a post-bulbar duodenal ulcer with endoscopic features that evoked malignant duodenal invasion. Although biopsies were negative for malignant cells, subsequent bleeding from the lesion suggested the progression of malignancy, which led to surgical resection. Pancreatoduodenectomy and pathological examination indicated that type 1 AIP was present. Simultaneously, the involvement of IgG4-related disease in the ulcerative lesion was suggested. To our knowledge, this is the first reported case of type 1 AIP complicated by post-bulbar duodenal ulcers, which was misdiagnosed as malignancy and considered an IgG4-related gastrointestinal disease associated with type 1 AIP.

Trends in inpatient burden from pressure injuries in the United States: Cross-sectional study National Inpatient Sample 2009-2019.

Pressure injuries are a significant comorbidity and lead to increased overall healthcare costs. Several European and global studies have assessed the burden of pressure injuries; however, no comprehensive analysis has been completed in the United States. In this study, we investigated the trends in the burden of pressure injuries among hospitalised adults in the United States from 2009 to 2019, stratified by sociodemographic subgroups. The length of admission, total cost of hospitalisation, and sociodemographic data was extracted from the National Inpatient Sample provided by the Healthcare Cost and Utilisation Project, Agency for Healthcare Research and Quality. Overall, the annual prevalence of pressure injuries and annual mean hospitalisation cost increased ($69,499.29 to $102,939.14), while annual mean length of stay decreased (11.14-9.90 days). Among all races, minority groups had higher average cost and length of hospitalisation. Our findings suggest that while the length of hospitalisation is decreasing, hospital costs and prevalence are rising. In addition, differing trends among racial groups exist with decreasing prevalence in White patients. Further studies and targeted interventions are needed to address these differences, as well as discrepancies in racial groups.

Etiopathology, Epidemiology, Diagnosis, and Treatment of Fungal Keratitis.

Fungal keratitis (FK) is a severe ocular condition resulting from corneal infection that is prevalent in tropical countries, particularly in developing regions of Asia and Africa. Factors like corneal lens misuse, inappropriate steroid use, and diagnostic challenges have provoked the epidemic. FK causes significant vision impairment, scarring, and ocular deformities. Accurate pathological diagnosis is crucial for effective therapeutic intervention. Topical antifungal therapy with surface healing medications proves effective in preventing fungal-borne ulcers. Managing FK requires a comprehensive understanding of fungal pathogenesis, guiding formulation strategies and preventive measures to curb global ocular blindness. This review provides in-depth insights into FK, covering etiology, epidemiology, pathogenesis, therapeutic interventions, antifungal resistance, limitations, prevention, and future perspectives on ocular surface disease management.

Dang-Gui-Si-Ni decoction facilitates wound healing in diabetic foot ulcers by regulating expression of AGEs/RAGE/TGF-ß/Smad2/3.

Diabetic foot ulcer (DFU) is a predominant complication of diabetes mellitus with poor prognosis accompanied by high amputation and mortality rates. Dang-Gui-Si-Ni decoction (DSD), as a classic formula with a long history in China, has been found to improve DFU symptoms. However, mechanism of DSD for DFU therapy remains unclear with no systematic elaboration. In vivo, following establishment of DFU rat model, DSD intervention with low, medium and high doses was done, with Metformin (DM) as a positive control group. With wound healing detection, pathological changes by HE staining, inflammatory factor expression by ELISA and qRT-PCR, oxidative stress levels by ELISA, and AGEs/RAGE/TGF-ß/Smad2/3 expression by Western blot were performed. In vitro, intervention with LY2109761 (TGF-ß pathway inhibitor) based on DSD treatment in human dermal fibroblast-adult (HDF-a) cells was made. Cell viability by CCK8, migration ability by cell scratch, apoptosis by flow cytometry, and AGEs/RAGE/TGF-ß/Smad2/3 expression by Western blot were measured. DFU rats exhibited elevated AGEs/RAGE expression, whereas decreased TGF-ß1 and p-Smad3/Smad3 protein expression, accompanied by higher IL-1ß, IL-6, TNF-α levels, and oxidative stress. DSD intervention reversed above effects. Glucose induction caused lower cell viability, migration, TGF-ß1 and p-Smad3/Smad3 protein expression, with increased apoptosis and AGEs/RAGE expression in HDF-a cells. These effects were reversed after DSD intervention, and further LY2109761 intervention inhibited DSD effects in cells. DSD intervention may facilitate wound healing in DFU by regulating expression of AGEs/RAGE/TGF-ß/Smad2/3, providing scientific experimental evidence for DSD clinical application for DFU therapy.

Correlation between initial serum 25-hydroxyvitamin D and granulation growth in diabetic foot ulcers.

OBJECTIVE: To determine the correlation between initial serum 25-hydroxyvitamin D (25(OH)D) levels with granulation growth in diabetic foot ulcers (DFUs) after 21 days of treatment. METHOD: This cohort study involved patients with type 2 diabetes who had a DFU treated at hospital. Blood samples were taken from patients on admission. The chemiluminescent immunoassay technique was used to measure 25(OH)D levels. Granulation tissue growth was analysed by comparing the photographs from the initial treatment to day 21 of treatment. RESULTS: The median value of 25(OH)D levels at initial treatment was 8 ng/ml. The result showed no correlation between 25(OH)D levels and the granulation growth in DFUs (p=0.86). CONCLUSION: The initial serum 25(OH)D level was not correlated with the growth of granulation tissue in DFUs.

A systematic review on the impact of sub-epidermal moisture assessments on pressure ulcer/injury care delivery pathways.

To assess all published studies which describe what happens to the delivery of pressure ulcer/injury (PI/PU) care pathways as a result of detecting raised sub-epidermal moisture (SEM) delta (∆ ≥ 0.6). We undertook a systematic review of the literature, and included original research studies using either a prospective or retrospective study design that report the impact that assessment using SEM assessments have on healthcare practitioners' delivery of PI/PU care pathways in adults at risk of developing PI/PUs. The review protocol was registered on PROSPERO (CRD42023416975). A literature search was conducted in May 2023, using PubMed, CINAHL, Scopus, Cochrane, EMBASE, Web of Science and Science Direct databases. Data were extracted using a data extraction tool including elements such as country, setting, sample size, intervention, control and quality appraisal was undertaken using the Evidence-based Librarianship. We identified nine papers published between 2017 and 2022. The majority of these studies were conducted in England (n = 6; 67%). The systematic review included studies conducted across multiple care settings including acute care, medical-surgical units, and palliative care, highlighting the importance of PI/PU prevention and management across diverse patient populations. The PI/PU care pathways implemented in the studies varied, but commonly included elements such as the application or increased use of pressure-redistributing mattresses/cushions, implementation of repositioning plans, management of incontinence and moisture, regular skin inspection, and assessment of patient mobility. Out of the nine studies identified, seven reported PI/PU incidence. A meta-analysis of seven studies (N = 18 451) demonstrated a statistically significant reduction in visual PI/PU development in favour of SEM-guided care pathways compared to usual care (the odds ratio = 0.36 [95% confidence interval: 0.24-0.53, p < 0.00001]). This systematic review provides evidence that implementing SEM assessments in patients at risk of developing PI/PUs prompts anatomy-specific clinical actions. The subsequent implementation of enhanced and targeted skin care interventions leads to consistent and sustained reductions in hospital-acquired PU incidence. The findings emphasise the importance of incorporating SEM assessments as part of comprehensive PI/PU prevention strategies in all care settings and patient populations. This systematic review is limited by the predominance of observational studies and variable study quality. Future research should focus on randomised trials in different care settings that monitor the efficacy of preventive interventions and their impact in reducing PI/PU incidence when implemented based on SEM assessments.

The Incidence of Skin and Soft Tissue Infections in the United States and Associated Healthcare Utilization Between 2010 and 2020.

Background: The number of patients with skin and soft tissue infections (SSTIs) in the United States appeared to be increasing well into the 21st century. However, no recent data have confirmed this trend. Methods: This retrospective, observational cohort study used claims data over 11 years (2010-2020) from Optum's de-identified Clinformatics Data Mart Database. SSTI episodes, complications, and comorbidities were identified using International Classification of Diseases codes. Annual SSTI incidence rates, proportions of recurrent SSTI, SSTI-associated deaths, and total costs were estimated. Results: During the study period, 5.4 million patients experienced 9.1 million SSTI episodes, with an incidence of 77.5 (95% confidence interval, 77.4-77.5) per 1000 person-years of observation (PYO). Annual incidence did not change significantly over time. Overall incidence (per 1000 PYO) of SSTI episodes in patients without comorbidities was 32.1 (highest incidence was for previous SSTI [113.5]) versus much higher rates if comorbidities were present. Incidence rates (per 1000 PYO) of chronic ulcers increased over time from 11.3 to 18.2 (P < .0001) and complicated disease from 3.5 to 6.3 (P < .0001). Deaths occurring within 30 days post-SSTI hospitalization rose from 2.6% to 4.6% in 2020. Recurrences occurred in 26.3% of index cases. The mean cost of an SSTI episode was US$3334 (median US$190) and was highest for surgical site infections and chronic ulcers. Conclusions: The epidemiology of SSTI in the United States is changing and the disease burden is increasing despite stabilization in overall incidence. These data can inform identification of priority populations who could benefit from targeted interventions.

Research on the mechanism of Guanyu Zhixie Granule in intervening gastric ulcers in rats based on network pharmacology and multi-omics.

Objective: Guanyu Zhixie Granule (GYZXG) is a traditional Chinese medicine compound with definite efficacy in intervening in gastric ulcers (GUs). However, the effect mechanisms on GU are still unclear. This study aimed to explore its mechanism against GU based on amalgamated strategies. Methods: The comprehensive chemical characterization of the active compounds of GYZXG was conducted using UHPLC-Q/TOF-MS. Based on these results, key targets and action mechanisms were predicted through network pharmacology. GU was then induced in rats using anhydrous ethanol (1 mL/200 g). The intervention effects of GYZXG on GU were evaluated by measuring the inhibition rate of GU, conducting HE staining, and assessing the levels of IL-6, TNF-α, IL-10, IL-4, Pepsin (PP), and epidermal growth factor (EGF). Real-time quantitative PCR (RT-qPCR) was used to verify the mRNA levels of key targets and pathways. Metabolomics, combined with 16S rRNA sequencing, was used to investigate and confirm the action mechanism of GYZXG on GU. The correlation analysis between differential gut microbiota and differential metabolites was conducted using the spearman method. Results: For the first time, the results showed that nine active ingredients and sixteen targets were confirmed to intervene in GU when using GYZXG. Compared with the model group, GYZXG was found to increase the ulcer inhibition rate in the GYZXG-M group (p < 0.05), reduce the levels of IL-6, TNF-α, PP in gastric tissue, and increase the levels of IL-10, IL-4, and EGF. GYZXG could intervene in GU by regulating serum metabolites such as Glycocholic acid, Epinephrine, Ascorbic acid, and Linoleic acid, and by influencing bile secretion, the HIF-1 signaling pathway, and adipocyte catabolism. Additionally, GYZXG could intervene in GU by altering the gut microbiota diversity and modulating the relative abundance of Bacteroidetes, Bacteroides, Verrucomicrobia, Akkermansia, and Ruminococcus. The differential gut microbiota was strongly associated with serum differential metabolites. KEGG enrichment analysis indicated a significant role of the HIF-1 signaling pathway in GYZXG's intervention on GU. The changes in metabolites within metabolic pathways and the alterations in RELA, HIF1A, and EGF mRNA levels in RT-qPCR experiments provide further confirmation of this result. Conclusion: GYZXG can intervene in GU induced by anhydrous ethanol in rats by regulating gut microbiota and metabolic disorders, providing a theoretical basis for its use in GU intervention.

Exploring the causal relationships between rheumatoid arthritis and oral phenotypes: a genetic correlation and Mendelian randomization study.

Background: Rheumatoid arthritis (RA) frequently presents with oral manifestations, including gingival inflammation, loose teeth, and mouth ulcers; however, the causal connections between these conditions remain unclear. This study aims to explore the genetic correlations and causal relationships between RA and prevalent oral phenotypes. Methods: Using summary data from genome-wide association studies of European populations, a cross-trait linkage disequilibrium score regression was conducted to estimate the genetic correlations between RA and six oral phenotypes. Subsequently, a two-sample Mendelian randomization (MR) approach was employed to assess the causal relationships, corroborated by various sensitivity analyses. Heterogeneity was addressed through the RadialMR method, while potential covariates were corrected using the multivariable MR approach. Results: A significant negative genetic correlation was detected between RA and denture usage (rg = -0.192, p = 4.88 × 10-8). Meanwhile, a heterogenous causal relationship between RA and mouth ulcers was observed (OR = 1.027 [1.005-1.05], p = 0.016, P heterogeneity = 4.69 × 10-8), which remained robust across sensitivity analyses. After excluding outlier variants, the results demonstrated robustly consistent (OR = 1.021 [1.008-1.035], p = 1.99 × 10-3, P heterogeneity = 0.044). However, upon adjusting for covariates such as smoking, alcohol consumption, body mass index, and obesity, the significance diminished, revealing no evidence to support independent genetic associations. Conclusion: Genetically predicted RA increases the risk of mouth ulcers, and a negative genetic correlation is identified between RA and denture use. The observed heterogeneity suggests that shared immunological mechanisms and environmental factors may play significant roles. These findings highlight the importance of targeted dental management strategies for RA patients. Further clinical guidelines are required to improve oral health among vulnerable RA patients.

Development of raft-forming liquid formulations loaded with ginger extract-solid dispersion for treatment of gastric ulceration.

Raft-forming liquid formulations incorporating ginger extract solid dispersion (GE-SD) were developed to achieve prolonged delivery of 6-gingerol in the stomach and thus increase the effectiveness of gastric ulcer treatment. The solubility of 6-gingerol in 0.1 N HCl (pH 1.2) was maximized (15 mg/mL) by combining ginger extract with PVP K30 at 1:3 w/w ratio to produce a solid dispersion. The nature of GE-SD was confirmed by PXRD and FT-IR analysis. PXRD pattern showed miscibility of GE and PVP K30 in amorphous solid dispersion and the FT-IR spectra confirmed the formation of hydrogen bond between GE and PVP K30. GE-SD-loaded raft-forming liquids were prepared using sodium alginate as a gel former and HPMC as a release-controlling agent. The formulations exhibited rapid floating behavior in 0.1 N HCl (<30 s) and remained afloat on the surface over 8 h. The formed raft structures provided sufficient strength (>7.5 g) and allowed sustained release of more than 70 % of the 6-gingerol content over 8 h in 0.1 N HCl. Raft-forming formulations incorporating ginger extract demonstrated anti-inflammatory activity by inhibiting nitric oxide production in LPS-stimulated RAW 264.7 macrophage cells (IC50 = 5.13 ± 0.07 µg/mL). Exposure to the formulations also had a significant cytotoxic effect on AGS human gastric adenocarcinoma cells with an IC50 of 17.45 ± 0.29 µg/mL. In addition, the raft-forming formulations enhanced the migratory behavior of L929 mouse fibroblasts in the scratch wound model. Taken together, these findings reveal the benefits of gastro-retentive, GE-SD-loaded raft-forming liquid formulations for improving the treatment of gastric ulcers.

Demographic and clinical characteristics of patients with varicose veins in Albania: a retrospective, single-centre analysis.

Introduction: Chronic venous disease (CVD) constitutes a frequently underdiagnosed pathological condition that progressively diminishes patients' quality of life and imposes an escalating strain on healthcare resources. This study aims to comprehensively investigate the epidemiological landscape of varicose vein disease, examining age group distributions, gender patterns, residence influences, marital status correlations, weight considerations, educational impacts, and various aspects related to varicose veins. Material and methods: This was a single-centre retrospective analysis, in Albania from May 2018 to September 2023. Data were collected retrospectively through hospital records. Data collection involved administering a structured questionnaire to study participants, categorically organised into three sections. The first section focused on collecting demographic information, the second section involved self-perception of identifying risk factors associated with varicose veins, and the final section included inquiries about the history of variceal surgery. Results: The CEAP classification distribution in our cohort revealed a predominant presence of C2 (varicose veins) in 53.3% of patients, followed by C3 (oedema) at 29.2%, and C4 (changes in skin and subcutaneous tissue secondary to CVD) at 10.5%, whereas C5 (healed venous ulcer) and C6 (active venous ulcer) were less frequent. Based on the body mass index (BMI) scale, data from patients indicated that 9.7% were in the category of underweight, 54.8% had a normal BMI, and 35.5% were categorised as overweight. Conclusions: The study's thorough exploration of patient perspectives, risk factors, and treatment choices contributes to a holistic understanding of varicose vein management, emphasising the importance of personalised approaches that account for demographic variations and individual beliefs.

Spider Bite Presenting as Fever, Macrophage Activation Syndrome and a Skin Ulcer.

Introduction: Fever of unknown origin (FUO) refers to a condition of prolonged increased body temperature, without identified causes. The most common cause of FUO worldwide are infections; arthropod bites (loxoscelism) should be considered in view of the spread of the fiddleback spider. Loxoscelism can present in a cutaneous form (a necrotic cutaneous ulcer) or in a systemic form with fever, haemolytic anaemia, rhabdomyolysis and, rarely, macrophage activation syndrome (MAS). For this suspicion, it is important to have actually seen the spider. Case description: A 71-year-old man was admitted to our department because of intermittent fever, arthralgia and a necrotic skin lesion on his right forearm that appeared after gardening. Laboratory tests were negative for infectious diseases, and several courses of antibiotics were administered empirically without clinical benefit. Whole-body computed tomography showed multiple colliquative lymphadenomegalies, the largest one in the right axilla, presumably of reactive significance. A shave biopsy of the necrotic lesion was performed: culture tests were negative and histological examination showed non-specific necrotic material, so a second skin and lymph node biopsy was performed. The patient developed MAS for which he received corticosteroid therapy with clinical/laboratory benefit. Cutaneous and systemic loxoscelism complicated by MAS was diagnosed. Subsequently, the second biopsy revealed morphological and immunophenotypic findings consistent with primary cutaneous anaplastic large cell lymphoma (PC-ALCL). Conclusions: Skin lesions and lymphadenomegalies of unknown origin should always be biopsied. It is very common to get indeterminate results, but this does not justify not repeating the procedure to avoid misdiagnosis. LEARNING POINTS: In case of necrotic skin lesions with fever, malignancy (and in particular cutaneous lymphoma) should always be considered.Misdiagnosis of loxoscelism is common. Definitive diagnosis requires the identification of the responsible spider.It is frequent to obtain inconclusive results from biopsies, but this does not justify not repeating the procedure to avoid misdiagnosis.

Oral Squamous Cell Carcinoma of the Right Buccal Mucosa: A Case Report.

Oral squamous cell carcinoma (OSCC) is indeed one of the most common types of oral cancer, typically affecting individuals over the age of 50. It primarily originates from the squamous epithelial cells lining the oral cavity. While it is relatively rare in individuals under 40 years old, it can still occur, albeit less frequently in that age group. Risk factors for developing OSCC include tobacco use (smoking or chewing), excessive alcohol consumption, chronic irritation (such as from poorly fitting dentures), human papillomavirus (HPV), infection, and certain dietary foods. Early detection and treatment are crucial for improving outcomes and reducing the mortality associated with this type of cancer. This report describes a case of OSCC, staged T2 N0 M0, involving the right buccal mucosa of a 51-year-old male patient. The patient reported intense pain in an ulcer on the right side of his cheek. This report focuses on the etiological factors and a brief literature review of squamous cell carcinoma.

Genital ulcer disease: Study of factors associated and utility of rapid diagnostic methods in current pandemic.

Background: Genital ulcer disease (GUD) is regarded as the most difficult conundrum for clinicians, as valid and rapid methods to diagnose them are limited, especially in India. The sexual behavior of an individual plays a role in the causation of GUD, and it depends on psychological, behavioral, and social well-being, which was significantly affected during the COVID-19 pandemic. Hence, the present study was undertaken to determine the etiology of genital ulcers by using simple, rapid microbiological methods and to study various factors associated with them. Materials and Methods: Various rapid tests like staining (Giemsa, Gram, and Diff Quick) and serology for antibody detection were used to diagnose agents causing genital ulcers among 71 suspected patients during the study period of 1 year. After due informed consent, sociodemographic and behavioral factors were recorded in proforma and analyzed. Results: Rapid tests could aid in diagnosing 47.9% of cases of GUD. Turnaround time was less than 60 minutes for all tests carried out. Genital herpes was the most common GUD followed by syphilis. Male gender (74.6%), age group of more than 34 years old (62%), literate (71.8%), and earning (70.4%) constituted most of the population presenting with GUD. Behavioral factors like promiscuity with a known person (83.1%) had a significant association (P 0.04) with GUD. Conclusion: Rapid diagnostic tests could assist in the early treatment of GUD cases. Factors like literacy, financial independence, and promiscuity with known individuals were associated with GUD in our study during the COVID-19 pandemic.

Clinical outcomes of radiofrequency ablation using a radiofrequency needle device for varicose ulcer: A non-randomized controlled prospective study.

OBJECTIVE: To evaluate the short-term clinical outcomes of radiofrequency ablation (RFA) using a radiofrequency (RF) needle device for varicose ulcers. METHODS: From September 2020 to September 2021, a total of 80 patients with varicose ulcers were included in this study. Based on the different surgical methods, the patients were divided into RF group and control groups, with 40 cases in each group. In the RF group, RFA was performed using an RF needle device and foam sclerotherapy was used for superficial veins. The control group was treated with conventional high-ligation stripping. The surgical data, hospitalization data, clinical efficacy, and postoperative complications of two groups were compared. Meanwhile, the correlation between RBC, HB, HCT, and ulcer healing time was analyzed. RESULTS: Compared to the control group, RF group had shorter surgery time, duration in the hospital, and less intraoperative bleeding (p < .05). The VCSS and CIVIQ scores in RF group were significantly higher than that in control group (p < .05). The healing time of ulcers was shorter in the RF group (x2 = 19.766, p = .000). The RF group had fewer postoperative complications. There was a positive correlation between RBC, HB, and HCT, and ulcer healing time (p < .05). CONCLUSION: The use of the RF needle device for RFA to treat patients with varicose ulcers showed acceptable short-term clinical outcomes with less incidence of trauma, faster recovery, and fewer complications.

Dose-dependent protective effects of Lactobacillus rhamnosus GG against stress-induced ulcer.

BACKGROUND: Stress-related diseases are on the rise and stress is one of the common factors that lead to ulcer. Stress-induced mucosal bleeding is a serious complication observed in many critically ill patients. Due to the harmful side effects of proton pump inhibitors, natural and active alternative treatment methods for peptic ulcer treatment that are safe in terms of side effects are an urgent need for human health. We aimed to investigate the dose-dependent protective effects of Lactobacillus rhamnosus GG (LGG) against stress ulcers induced by cold restraint stress in rats. This study was performed in a total of 42 rats, in control group (C), stress group (S), pantoprazol (20 mg kg-1 day-1) group (P), LGG (3 × 108 cfu mL-1 day-1) + stress group (M1), LGG (15 × 108 mL-1 day-1) + stress group (M5) and LGG (30 × 108 mL-1 day-1) + stress group (M10) (each n = 7). Ulceration areas (mm2) were determined quantitatively with ImageJ software. Glucocorticoid, catalase (CAT), superoxide dismutase (SOD) and glutathione peroxidase (GPx) levels were determined by ELISA and malondialdehyde levels were determined by spectrophotometric measurement. Histopathological examinations were performed in gastric tissue. RESULTS: Therapeutic dose of LGG increased CAT, SOD and GPx levels; prevented excessive activation of the hypothalamic-pituitary-adrenal axis; reduced ulceration and bleeding in the gastric mucosal layer; and provided stabilization of mast cells. CONCLUSIONS: We can suggest that LGG may be beneficial for reducing the negative effects of stress on the body, for protecting against ulcer disease and for reducing or preventing the risk of stress-induced gastrointestinal bleeding in patients staying in intensive care units. © 2024 The Author(s).

Comparative effectiveness of sodium-glucose cotransporter-2 inhibitors for new-onset gastric cancer and gastric diseases in patients with type 2 diabetes mellitus: a population-based cohort study.

OBJECTIVE: To compare the risks of gastric cancer and other gastric diseases in patients with type-2 diabetes mellitus (T2DM) exposed to sodium-glucose cotransporter 2 inhibitors (SGLT2I), dipeptidyl peptidase-4 inhibitors (DPP4I) or glucagon-like peptide-1 receptor agonists (GLP1a). DESIGN: This was a population-based cohort study of prospectively collected data on patients with T2DM prescribed SGLT2I, DPP4I or GLP1a between January 1st 2015 and December 31st 2020 from Hong Kong. The outcomes were new-onset gastric cancer, peptic ulcer (PU), acute gastritis, non-acute gastritis, and gastroesophageal reflux disease (GERD). Propensity score matching (1:1) using the nearest neighbour search was performed, and multivariable Cox regression was applied. A three-arm comparison between SGLT2I, DPP4I and GLP1a was conducted using propensity scores with inverse probability of treatment weighting. RESULTS: A total of 62,858 patients (median age: 62.2 years old [SD: 12.8]; 55.93% males; SGLT2I: n = 23,442; DPP4I: n = 39,416) were included. In the matched cohort, the incidence of gastric cancer was lower in SGLT2I (Incidence rate per 1000 person-year, IR: 0.32; 95% confidence interval, CI 0.23-0.43) than in DPP4I (IR per 1000 person-year: 1.22; CI 1.03-1.42) users. Multivariable Cox regression found that SGLT2I use was associated with lower risks of gastric cancer (HR 0.30; 95% CI 0.19-0.48), PU, acute gastritis, non-acute gastritis, and GERD (p < 0.05) compared to DPP4I use. In the three-arm analysis, GLP1a use was associated with higher risks of gastric cancer and GERD compared to SGLT2I use. CONCLUSIONS: The use of SGLT2I was associated with lower risks of new-onset gastric cancer, PU, acute gastritis, non-acute gastritis, and GERD after matching and adjustments compared to DPP4I use. SGLT2I use was associated with lower risks of GERD and gastric cancer compared to GLP1a use.

Use of carbon dioxide fractional laser in the management of lower limb ischemia in patients with diabetes: a case report : CO2 fractional laser in the treatment of diabetic foot.

Treatment of lower limb ischemia in patients with diabetes is challenging because of the location of the ulcers and the complexity of their pathogenesis. Carbon dioxide fractional laser (CO2FL) therapy in conjunction with tibial periosteum distraction could become a substitute for conventional methods. We herein describe a patient diagnosed with ischemic diabetic foot with a complex ulcer in the upper third of the tibia. Laser irradiation (Deep FX mode with 30 mJ of energy and 10% density) was applied to the entire region of skin below the knee after surface anesthesia, and this treatment was performed twice a week until the ulcer healed. Computed tomography angiography showed successful establishment of a blood supply to the back of the right foot after treatment. Skin grafting was successfully performed, with only a few wounds remaining on the foot 8 months after treatment. The pain score was significantly decreased at the last follow-up. No complications occurred. This case report provides guidance for the performance of CO2FL, a fast, easy, accurate treatment in patients with diabetes. CO2FL can target lower limb arterial occlusive disease accompanied by refractory ulcers, addressing the underlying vascular occlusion and dysfunction as well as promoting microcirculation and wound healing.

The rat as an animal model in chronic wound research: An update.
