Effects of Freshwater Acidification on the Gut Microbial Community of Trachemys scripta elegans.

Freshwater acidification (FA) has become a global environmental problem, posing a potential threat to freshwater ecosystems. The gut microbiota plays a crucial role in the host's response and adaptation to new environments. In this study, we investigated the changes in microbial communities in Red-eared slider (Trachemys scripta elegans) under acidic conditions to reveal the ecological impacts of acidification on freshwater turtles. The results showed that there were significant differences in ß-diversity (p = 0.03), while there were no significant differences in the α-diversity of gut microbiota in T. s. elegans between the different levels of acidification (pH of 5.5, 6.5, 7.5). Both the Gut Microbiome Health Index (GMHI) and the Microbial Dysbiosis Index (MDI) exhibited significant differences when comparing environments with a pH of 5.5 to those with a pH of 6.5 (p < 0.01). A comparative analysis between pH levels of 5.5 and 6.5 also revealed substantial differences (p < 0.01). Likewise, a comparative analysis between pH levels of 6.5 and 7.5 also revealed substantial differences (p < 0.01). At the phylum level, Firmicutes, Fusobacteria, and Bacteroidota formed a major part of the gut microbial community, Fusobacteria showed significant differences in different acidity environments (p = 0.03). At the genus level, Cetobacterium, Turicibacter, unclassified Eubacteriaceae, and Anaerorhabdus_furcosa_group showed significant differences in different acidity environments. The pH reduced interactivity in the gut microbiota of T. s. elegans. In addition, LEfSe analysis and functional prediction revealed that the potentially_pathogenic and stress_tolerant functional characteristics also showed significant differences in different acidity environments. The findings underscore the pivotal role of the gut microbiota in T. s. elegans in response to freshwater acidification and provide a foundation for further exploration into the impacts of acidification on freshwater ecosystems.

Improvement in Inhaler Techniques After Training and Counseling in Patients With Chronic Obstructive Pulmonary Disease or Asthma.

Background Chronic respiratory diseases such as chronic obstructive pulmonary disease (COPD) and asthma significantly impair quality of life and impose a substantial burden on healthcare systems. Proper inhalation technique is important for effective management of these diseases, yet remains poorly performed by many patients. This study evaluated the impact of structured counseling and training sessions on inhaler use among patients with COPD and asthma, aiming to enhance technique correctness and disease control. Methodology This cross-sectional study analyzed 150 patients with asthma and COPD who fulfilled the inclusion criteria for inhalation techniques. Patients were counseled regarding the proper seven-step inhalation technique for each inhaler type [metered-dose inhaler (MDI), MDI with spacer, and dry powder inhaler (DPI)] through practical demonstration at baseline visits. Correct use of inhalers was assessed by a predefined checklist for each inhaler device at the baseline visit and after three months. The correctness of the inhalation technique was evaluated by scoring each of the seven steps. The disease control assessment was done using the COPD assessment test (CAT) and asthma control test (ACT) at the baseline visit and after three months. Results In this study of 150 patients, there were 97 (64.7%) males and 53 (35.3%) females. In total, 67 (44.7%) were diagnosed with asthma and 83 (55.3%) with COPD. The mean age was 45.33 ± 12.62 years. Post-counseling improvements in inhaler technique were marked, with MDI users enhancing their technique score from an average of 4.4 to 6.1, MDI with spacer from 4.56 to 6.26, and DPI from 4.92 to 6.24 (p < 0.001 for all). Disease control also showed significant gains; CAT scores decreased for MDI users from 23.4 to 20.5, MDI with spacer from 23.92 to 20.96, and DPI from 24.89 to 21.96. Concurrently, ACT scores increased for MDI users from 16.4 to 18.0 (p = 0.002), MDI with spacer from 17.29 to 19.04, and DPI from 16.42 to 18.37 (p < 0.001 for both), reflecting substantive advances in managing COPD and asthma symptoms. Furthermore, patients with primary education exhibited a significant boost in technique mastery post-counseling (p < 0.001), underscoring the potential of well-crafted counseling to transcend educational barriers in promoting effective inhaler use. Conclusions Post-counseling, inhaler technique improved significantly across all types, with MDI with spacer users demonstrating the most progress. Technique scores increased notably (p < 0.001), and disease control scores for COPD and asthma, measured by CAT and ACT, also showed significant improvements (p < 0.001). Remarkably, primary education level participants exhibited substantial technique gains post-intervention, emphasizing the effectiveness of counseling irrespective of initial educational status in enhancing inhaler use and disease management.

Nine years of patch testing with isocyanates in a clinic of occupational dermatology.

BACKGROUND: Isocyanates are used as starting materials of polyurethane (PU) products. They are relatively important occupational skin sensitizers. OBJECTIVES: To analyse results of a large isocyanate patch test series of 19 isocyanate test substances and 4,4'-diaminodiphenylmethane (MDA), a marker of 4,4'-diphenylmethane diisocyanate (MDI) hypersensitivity. METHODS: Test files were screened for positive reactions in the isocyanate series. Patients with positive reactions were analysed for occupation, exposure and diagnosis. RESULTS: In 2010-2019, 53 patients had positive reactions in the series (16% of 338 patients tested). MDA, the well-established screening substance for MDI allergy, was positive in 30 patients, an in-house monomeric MDI test substance in 23 patients and 3 different polymeric MDI test substances in 19-21 patients. We diagnosed 16 cases of occupational allergic contact dermatitis (OACD) from MDI including 3 pipe reliners. Hexamethylene-1,6-diisocyanate (HDI) oligomers in paint hardeners caused 5 cases of OACD, more cases than 2,4-toluene diisocyanate (TDI; n = 3) and isophorone diisocyanate (IPDI; n = 1) put together. CONCLUSIONS: In contrast to previous studies, polymeric MDI test substances were not superior to a monomeric MDI. Pipe reliners may get sensitised not only by epoxy products and acrylates but also by MDI in hardeners of PU pipe coatings. HDI oligomers were the second most important causes of OACD after MDI.

Evaluation of the Metered Dose Inhaler Technique: Initial Assessment and Post-counseling Improvements Among the Indian Population.

Objective The objective of this study was to evaluate errors in the use of metered-dose inhalers (MDIs) among patients diagnosed with asthma or chronic obstructive pulmonary disease (COPD). Additionally, we aimed to assess improvements following corrective interventions. Settings and design This cross-sectional study was done by simple random sampling. Methods and materials This study was done at a tertiary care center in South India in an outpatient department and ward for tuberculosis and chest disease to find out the right way to use an MDI and investigate the reasons why people with asthma and COPD don't use it correctly. There were a total of 12 steps. The patient was given an empty canister to try the inhalation technique and was scored one point for every correct step and zero for every incorrect step, for a total of 12 steps. Following the demonstration, an educator used a variety of tools, including verbal communication, pictorial demonstrations, and practical demonstrations, to correct the mistakes. After education was provided, post-interventional data was collected. Results During pre-intervention of the 12 steps out of the 183 participants, step one had 183 correct participants (100%), step two had 104 correct participants (56.83%), step three had 129 correct participants (70.49%), step four had 71 correct participants (38.79%), step five had 167 correct participants (91.25%), step six had 123 correct participants (67.21%), step seven had 132 correct participants (72.13%), step eight had 81 correct participants (43.71%), step nine had 123 correct participants (67.21%), step 10 had 108 correct participants (59.01%), step 11 had 128 correct participants (69.94%), and step 12 had 175 correct participants (95.62%). During the post-intervention of the 12 steps, out of the 183 participants, step one remained at 183 correct participants (100%), step two increased to 149 correct participants (81.42%), step three to step seven increased to 183 correct participants (100%), step eight increased to 142 correct participants (77.59%), step nine increased to 174 correct participants (95.08%), step 10 increased to 177 correct participants (96.72%), step 11 increased to 143 correct participants (78.14%) and step 12 increased to 177 correct participants (96.72%). Conclusion This study highlights the prevalent errors in the use of metered-dose inhalers (MDIs) among patients diagnosed with asthma or chronic obstructive pulmonary disease (COPD). The results demonstrate significant improvements in the MDI technique. Following educational interventions such as verbal communication, pictorial demonstrations, and practical exercises, patients were able to correct their inhaler technique effectively and emphasized the importance of patient education and counseling to ensure the maintenance of correct usage over time.

Addressing the Burden of Multiple Daily Insulin Injections in Type 2 Diabetes with Insulin Pump Technology: A Narrative Review.

The growing prevalence of type 2 diabetes (T2D) remains a leading health concern in the US. Despite new medications and technologies, glycemic control in this population remains suboptimal, which increases the risk of poor outcomes, increased healthcare resource utilization, and associated costs. This article reviews the clinical and economic impacts of suboptimal glycemic control in patients on basal-bolus insulin or multiple daily injections (MDI) and discusses how new technologies, such as tubeless insulin delivery devices, referred to as "patch pumps", have the potential to improve outcomes in patients with T2D.

Multidirectional instability of the shoulder: a systematic review with a novel classification.

Purpose: A variety of instabilities are grouped under multidirectional instability (MDI) of the shoulder. This makes understanding its diagnostic process, presentation and treatment difficult due to lack of evidence-based consensus. This review aims to propose a novel classification for subtypes of MDI. Methods: A systematic search was performed on PubMed Medline and Embase. A combination of the following 'MeSH' and 'non-MesH' search terms were used: (1) Glenohumeral joint[tiab] OR Glenohumeral[tiab] OR Shoulder[tiab] OR Shoulder joint[tiab] OR Shoulder[MeSH] OR Shoulder joint[MeSH], (2) Multidirectional[tiab], (3) Instability[tiab] OR Joint instability[MeSH]. Sixty-eight publications which met our criteria were included. Results: There was a high degree of heterogeneity in the definition of MDI. Thirty-one studies (46%) included a trauma etiology in the definition, while 23 studies (34%) did not. Twenty-five studies (37%) excluded patients with labral or bony injuries. Only 15 (22%) studies defined MDI as a global instability (instability in all directions), while 28 (41%) studies considered MDI to be instability in two directions, of which one had to include the inferior direction. Six (9%) studies included the presence of global ligamentous laxity as part of the definition. To improve scientific accuracy, the authors propose a novel AB classification which considers traumatic etiology and the presence of hyperlaxity when subdividing MDI. Conclusion: MDI is defined as symptomatic instability of the shoulder joint in two or more directions. A comprehensive classification system that considers predisposing trauma and the presence of hyperlaxity can provide a more precise assessment of the various existing subtypes of MDI. Level of Evidence: III.

MicroRNA-mediated Krüppel-like factor 4 upregulation induces alternatively activated macrophage-associated marker and chemokine transcription in 4,4'-methylene diphenyl diisocyanate exposed macrophages.

1. Occupational exposure to 4,4'-methylene diphenyl diisocyanate (MDI) is associated with occupational asthma (OA) development. Alveolar macrophage-induced recruitment of immune cells to the lung microenvironment plays an important role during asthma pathogenesis. Previous studies identified that MDI/MDI-glutathione (GSH)-exposure downregulates endogenous hsa-miR-206-3p/hsa-miR-381-3p. Our prior report shows that alternatively activated (M2) macrophage-associated markers/chemokines are induced by MDI/MDI-GSH-mediated Krüppel-Like Factor 4 (KLF4) upregulation in macrophages and stimulates immune cell chemotaxis. However, the underlying molecular mechanism(s) by which MDI/MDI-GSH upregulates KLF4 remain unclear.2. Following MDI-GSH exposure, microRNA(miR)-inhibitors/mimics or plasmid transfection, endogenous hsa-miR-206-3p/hsa-miR-381-3p, KLF4, or M2 macrophage-associated markers (CD206, TGM2), and chemokines (CCL17, CCL22, CCL24) were measured by either RT-qPCR, western blot, or luciferase assay.3. MDI-GSH exposure downregulates hsa-miR-206-3p/hsa-miR-381-3p by 1.46- to 9.75-fold whereas upregulates KLF4 by 1.68- to 1.99-fold, respectively. In silico analysis predicts binding between hsa-miR-206-3p/hsa-miR-381-3p and KLF4. Gain- and loss-of-function, luciferase reporter assays and RNA-induced silencing complex-immunoprecipitation (RISC-IP) studies confirm the posttranscriptional regulatory roles of hsa-miR-206-3p/hsa-miR-381-3p and KLF4 in macrophages. Furthermore, hsa-miR-206-3p/hsa-miR-381-3p regulate the expression of M2 macrophage-associated markers and chemokines via KLF4.4. In conclusion, hsa-miR-206-3p/hsa-miR-381-3p play a major role in regulation of MDI/MDI-GSH-induced M2 macrophage-associated markers and chemokines by targeting the KLF4 transcript, and KLF4-mediated regulation in macrophages.

The IDEAL (Insulin therapy DE-intensificAtion with iglarLixi) Randomised Controlled Trial-Study Design and Protocol.

INTRODUCTION: Multiple daily injection insulin regimen (MDI) represents the most intensive insulin regimen used in the management of people with type 2 diabetes (PwT2D). Its efficacy regarding glycaemic control is counterbalanced by the increased risk of hypoglycaemia, frequently observed tendency to weight gain and necessity for frequent glucose monitoring. Recent introduction of novel antidiabetic medications with pleiotropic effects reaching far beyond the reduction of glycaemia (HbA1c), such as the glucagon-like peptide 1 receptor agonist (GLP-1 RA), has significantly widened the therapeutic options available for management of T2D. Consequently, there is currently a substantial number of PwT2D for whom the MDI regimen was initiated at a time when no other options were available. Yet, in present times, these individuals could benefit from simplified insulin regimens ideally taking advantage of the beneficial effects of the novel classes of antidiabetic medications. iGlarLixi (Suliqua®) is a once-daily fixed-ratio combination of basal insulin analogue glargine 100 U/ml and a GLP-1 RA lixisenatide. METHODS: Insulin therapy DE-intensificAtion with iglarLixi (IDEAL) is a six-centre, open-label, parallel-group, active comparator, phase IV randomised controlled trial with a 24-week active treatment period examining the efficacy and safety of MDI regimen de-intensification with once-daily administration of iGlarLixi versus MDI regimen continuation in PwT2D on a backgroud therapy with metformin ± sodium-glucose cotransporter 2 inhibitor. PLANNED OUTCOMES: The primary objective is to compare the effects of MDI therapy de-intensification with iGlarLixi versus MDI regimen continuation regarding glycaemic control (HbA1c). Secondary objectives include detailed evaluation of the effects of MDI regimen de-intensification with iGlarLixi on glycaemic control using standardised continuous glucose monitoring (CGM) metrics and self-monitoring of plasma glucose. Furthermore, body weight and body composition analysis, quality of life and safety profile are evaluated. TRIAL REGISTRATION: ClinicalTrials.gov, identifier NCT04945070.

Psychometric validation of the Danish version of the Major Depression Inventory using data from the Lolland-Falster health study (LOFUS).

PURPOSE: The Major Depression Inventory (MDI) is a widely used self-rating depression scale commonly in primary care in Denmark. It has not been subject to robust psychometric validation in a general population setting. The aim of this study was to evaluate the psychometric measurement properties of the MDI when applied in the general population. METHODS: We evaluated statistical psychometric validity using modern test theory (confirmatory factor analysis, item response theory models and Rasch measurement theory) testing local independence and differential item function across groups defined by gender, age, education, and chronic disease status. Separate analyses across different strata and across different statistical models were employed. RESULTS: Regarding structural validity we consistently identified local dependence for the item two pairs (MDI2,MDI3) and (MDI4,MDI5) across strata. This result was confirmed by bifactor CFA models and item screening. We further identified substantial differential item functioning with respect to age group and with respect to chronic disease. We identified quantified the magnitude of this lack of measurement invariance. CONCLUSION: The MDI is psychometrically valid in homogenous sub populations, but the disclosed evidence of local dependence means that published estimates of its reliability cannot be trusted. The lack of measurement invariance means that the instrument cannot be used to compare individuals or groups unless they are similar in terms of age group and chronic disease status.

Effectiveness of Insulin Pump Therapy Versus Multiple Daily Injections for Glycemic Control and Rate of Diabetic Ketoacidosis Among Children With Type 1 Diabetes Mellitus.

Background Advances in pump technology and the availability of insulin analogs, as well as the results of the Diabetes Control and Complications Trial (DCCT), which established the benefit of improved glycemic control, have all contributed to the increased use of insulin pump therapy in recent years, particularly in children. Purpose This research aims to compare the impact of insulin delivery method, i.e., continuous subcutaneous insulin infusion (CSII) or multiple daily injections (MDI) on glycemic control and the rate of diabetic ketoacidosis (DKA) among children with type 1 diabetes mellitus in Al Ahsa, Saudi Arabia. Methods  A retrospective cohort study was carried out in a diabetic center in Al Ahsa, Saudi Arabia, over 24 months (2020-2022) among children with type I diabetes mellitus (age group 1-14 years). Results  In total, 351 patients with diabetes were induced, with 316 (90%) on MDI and 35 (10%) on CSII. After six months of diagnosis, precisely 38 (12%) of patients with diabetes on the MDI regimen experienced DKA, compared to 4 (11.4%) of those on the CSII regimen, with no statistically significant difference (P=0.918). At six months and nine months of follow-up, the average hemoglobin A1c (HbA1c) was considerably higher in diabetic patients on MDI (8.9 ± 1.7% vs. 8.2 ± 1.5% and 9.1 ± 1.6% vs. 8.0 ± 1.3%, respectively, with a significant p-value ≤0.05). Conclusion In this study, we found that patients on the MDI regimen had considerably higher HbA1c levels than patients on the CSII regimen, but there was no statistically significant difference in DKA rates between them. This is a short-term follow-up study, and we recommend that patients be followed for a longer period of time for further accurate outcomes.

Complex multi-dimensional integration for T2* and R2* mapping.

A dual Multi-Dimensional Integration (dMDI) method was proposed and demonstrated for T2* and R2* mapping. By constructing and jointly using both the original MDI term and an inversed MDI term, T2* and R2* mapping can be performed independently with intrinsic background noise suppression and spike elimination, allowing for high quantitative accuracy and robustness over a wide range of T2*. dMDI was compared to original MDI and curve fitting methods in terms of quantitative specificity, accuracy, reliability and computational efficiency. All methods were tested and compared via simulation and in vivo data. With high signal-to-noise-ratio (SNR), the proposed dMDI method yielded T2*and R2* values similar to curve fitting methods. For low SNR and background noise signals, the dMDI yielded low T2* and R2* values, thus effectively suppressing all background noise. Virtually zero spikes were observed in dMDI T2* and R2* maps in all simulation and imaging results. The dMDI method has the potential to provide improved and reliable T2* and R2* mapping results in routine and SNR-challenging scenarios.

Performance of Particleboard Made of Agroforestry Residues Bonded with Thermosetting Adhesive Derived from Waste Styrofoam.

This paper investigated the upcycling process of thermoplastic waste polystyrene (WPS) into thermosetting particleboard adhesive using two cross-linkers, namely methylene diphenyl diisocyanate (MDI) and maleic anhydride (MA). The WPS was dissolved in an organic co-solvent. The weight ratio of WPS/co-solvent was 1:9, and 10% of cross-linkers based on the WPS solids content were added subsequently at 60 °C under continuous stirring for 30 min. The adhesive properties, cohesion strength, and thermo-mechanical properties of WPS-based adhesives were examined to investigate the change of thermoplastic WPS to thermosetting adhesives. The bonding strength of WPS-based adhesives was evaluated in particleboard made of sengon (Falcataria moluccana (Miq.) Barneby & J.W. Grimes) wood and rice straw particles at different weight ratios according to the Japanese Industrial Standard (JIS) A 5908:2003. Rheology and Dynamic Mechanical Analysis revealed that modification with MDI and MA resulted in thermosetting properties in WPS-based adhesives by increasing the viscosity at a temperature above 72.7 °C and reaching the maximum storage modulus above 90.8 °C. WPS modified with MDI had a lower activation energy (Ea) value (83.4 kJ/mole) compared to the WPS modified with MA (150.8 kJ/mole), indicating the cross-linking with MDI was much faster compared with MA. Particleboard fabricated from 100% sengon wood particles bonded with WPS modified with MDI fulfilled the minimum requirement of JIS A 5908:2003 for interior applications.

Advanced decision support system for individuals with diabetes on multiple daily injections therapy using reinforcement learning and nearest-neighbors: In-silico and clinical results.

Many individuals with diabetes on multiple daily insulin injections therapy use carbohydrate ratios (CRs) and correction factors (CFs) to determine mealtime and correction insulin boluses. The CRs and CFs vary over time due to physiological changes in individuals' response to insulin. Errors in insulin dosing can lead to life-threatening abnormal glucose levels, increasing the risk of retinopathy, neuropathy, and nephropathy. Here, we present a novel learning algorithm that uses Q-learning to track optimal CRs and uses nearest-neighbors based Q-learning to track optimal CFs. The learning algorithm was compared with the run-to-run algorithm A and the run-to-run algorithm B, both proposed in the literature, over an 8-week period using a validated simulator with a realistic scenario created with suboptimal CRs and CFs values, carbohydrate counting errors, and random meals sizes at random ingestion times. From Week 1 to Week 8, the learning algorithm increased the percentage of time spent in target glucose range (4.0 to 10.0 mmol/L) from 51 % to 64 % compared to 61 % and 58 % with the run-to-run algorithm A and the run-to-run algorithm B, respectively. The learning algorithm decreased the percentage of time spent below 4.0 mmol/L from 9 % to 1.9 % compared to 3.4 % and 2.3 % with the run-to-run algorithm A and the run-to-run algorithm B, respectively. The algorithm was also assessed by comparing its recommendations with (i) the endocrinologist's recommendations on two type 1 diabetes individuals over a 16-week period and (ii) real-world individuals' therapy settings changes of 23 individuals (19 type 2 and 4 type 1) over an 8-week period using the commercial Bigfoot Unity Diabetes Management System. The full agreements (i) were 89 % and 76 % for CRs and CFs for the type 1 diabetes individuals and (ii) was 62 % for mealtime doses for the individuals on the commercial Bigfoot system. Therefore, the proposed algorithm has the potential to improve glucose control in individuals with type 1 and type 2 diabetes.

Insulin Pump Therapy vs Multiple Daily Insulin Injections for Glycemic Control in Children With Type 1 Diabetes: A Systematic Review and Meta-Analysis.

Type 1 diabetes mellitus (T1DM), characterized by the autoimmune destruction of pancreatic beta cells and consequent insulin deficiency, leads to various complications. Management primarily focuses on optimal glycemic control through intensive insulin therapy, either via multiple daily injections (MDI) or continuous subcutaneous insulin infusion (CSII) using insulin pumps, which offer flexibility and improved basal insulin delivery. Despite the benefits of insulin pumps, such as reduced hypoglycemia risk and better mealtime insulin management, they pose challenges such as complexity in site changes and potential ketoacidosis due to tubing issues. This systematic review adheres to PRISMA guidelines and compares CSII with MDI in children and adolescents with T1DM, concentrating on outcomes such as glycemic control measured with HbA1c and glucose levels. The review includes studies meeting stringent criteria, encompassing a broad range of methodologies and geographies. The findings of this meta-analysis indicate the differences in glycemic control with CSII compared to MDI. However, significant heterogeneity in results and methodological variations across studies necessitate cautious interpretation. The study underscores the potential of CSII in offering better control for some patients, supporting a more personalized approach to T1DM management. It highlights the need for further research to understand the long-term effects and to refine treatment protocols, considering the variations in healthcare systems, treatment approaches, and patient demographics globally.

Promoting knowledge of metered dose inhaler (MDI) usage among pharmacy professional students through a mobile app.

INTRODUCTION: Efficient asthma management necessitates optimal usage of metered-dose inhalers (MDIs). As future health professionals, pharmacy students are pivotal in disseminating accurate methodologies for MDI usage. Despite having hands-on experience, there is room to enhance their comprehension, highlighting the need for prompt patient educational interventions. OBJECTIVE: This study aims to evaluate the effectiveness of a mobile app-assisted educational method in improving pharmacy students' understanding of MDI usage. METHODS: A pre-experimental study was conducted from March to August 2021 with 45 participants enrolled in the Pharmacist Professional Study Program at the Faculty of Medicine and Health Sciences, Universitas Muhammadiyah Yogyakarta. Using a one-group pretest-post-test design, the study measured the app's impact on students' knowledge and MDI usage skills. RESULTS: The intervention significantly improved students' scores on a 9-step MDI usage checklist, with increases ranging from 0.10 to 0.50 across verbal and motor components. A Mann-Whitney U test validated these findings, showing a statistically significant p-value of 0.001. CONCLUSION: The mobile app-assisted educational approach substantially enhanced pharmacy students' proficiency in MDI use. The significant rise in mean scores for the 9-step checklist, along with the notable p-value, supports the effectiveness of this intervention in healthcare education.

4,4'-Methylene diphenyl diisocyanate exposure induces expression of alternatively activated macrophage-associated markers and chemokines partially through Krüppel-like factor 4 mediated signaling in macrophages.

Occupational exposure to the most widely used monomeric diisocyanate (dNCO), 4,4'-methylene diphenyl diisocyanate (MDI), may lead to the development of occupational asthma (OA). Alveolar macrophages with alternatively activated (M2) phenotype have been implicated in allergic airway responses and the pathogenesis of asthma. Recent in vivo studies demonstrate that M2 macrophage-associated markers and chemokines are induced by MDI-exposure, however, the underlying molecular mechanism(s) by which this proceeds is unclear.Following MDI exposure (in vivo and in vitro) M2 macrophage-associated transcription factors (TFs), markers, and chemokines were determined by RT-qPCR, western blots, and ELISA.Expression of M2 macrophage-associated TFs and markers including Klf4/KLF4, Cd206/CD206, Tgm2/TGM2, Ccl17/CCL17, Ccl22/CCL22, and CCL24 were induced by MDI/MDI-GSH exposure in bronchoalveolar lavage cells (BALCs)/THP-1 macrophages. The expression of CD206, TGM2, CCL17, CCL22, and CCL24 are upregulated by 3.83-, 7.69-, 6.22-, 6.08-, and 1.90-fold in KLF4-overexpressed macrophages, respectively. Endogenous CD206 and TGM2 were downregulated by 1.65-5.17-fold, and 1.15-1.78-fold, whereas CCL17, CCL22, and CCL24 remain unchanged in KLF4-knockdown macrophages. Finally, MDI-glutathione (GSH) conjugate-treated macrophages show increased chemotactic ability to T-cells and eosinophils, which may be attenuated by KLF4 knockdown.Our data suggest that MDI exposure may induce M2 macrophage-associated markers partially through induction of KLF4.

Improving Clinician Confidence in Insulin Prescriptions at Discharge for Individuals With Newly Diagnosed Type 1 Diabetes.

Background In a questionnaire, we found that pediatric clinicians at Basildon and Thurrock University Hospital (BTUH) have low confidence levels in prescribing multiple daily injections (MDI) for newly diagnosed pediatric patients with type 1 diabetes mellitus. We designed and evaluated locally tailored prescription guidance to improve confidence in MDI discharge prescriptions for pediatric doctors of all grades. Methods We designed a prescription guidance tool by adapting existing local guidelines to improve clinician familiarity with MDI prescriptions and prevent prescription errors. The intervention was delivered in a single pediatric unit to doctors of all levels. Feedback was collected, and the clinicians' confidence in their MDI prescriptions was evaluated before and after the intervention. Questionnaires were distributed to all pediatric doctors within the unit to assess their confidence in prescribing MDIs using a five-point Likert Scale. Furthermore, the questionnaires aimed to determine whether clinicians regularly consulted the existing local guidelines. Local guidelines were adapted in consultation with the local pediatric diabetic multidisciplinary team (MDT) and with reference to the East of England Pediatric Diabetes Network to present MDI guidance in a more concise format, which includes an example MDI discharge medication checklist. Following approval by the local guidelines management group, additional changes were made to enhance the practicality and accessibility of the discharge prescription guidance for clinicians. These guidelines were distributed to the pediatric MDT via email and displayed in visible areas of the department. Results Out of the 13 doctors surveyed, 10 provided pre- and post-intervention feedback (77%). Statistical significance was calculated using unpaired t-tests. Ninety percent of pediatric doctors routinely refer to local guidelines for guidance on MDI prescriptions. However, 50% of respondents felt that existing local guidelines were not easily accessible, given the time and effort required to locate them. The mean confidence score for completing MDI prescriptions at discharge before the intervention was 1.9 (SD: 0.83). After the intervention, it increased to 4 (SD: 0.63) (95% CI: 2.79-1.41, p<0.0001). Ninety percent of pediatric doctors felt that the design and display of the MDI guidelines optimized patient care. Conclusions Following the presentation of the project at a local audit and quality improvement (QI) meeting, the adapted guidelines were included in the junior doctor induction program at BTUH and made accessible on the local intranet. The production of locally tailored prescription guidance for MDI prescriptions at discharge has led to an increase in the confidence of pediatric doctors when writing their prescriptions. We aimed to continue updating this guidance as necessary and making further developments to enhance clinician confidence.

Comparative Study of Inhaled Fluticasone Versus Oral Prednisone in 30 Dogs with Cough and Tracheal Collapse.

Coughing is common in dogs with tracheal collapse (TC). The use of inhaled corticosteroids is less widespread than oral ones. This study aims to compare the effects of oral and inhaled corticosteroids in dogs with cough and TC. Thirty dogs were prospectively included and randomized to the prednisone oral group (OG, 14) or fluticasone inhaled group (IG, 16). A clinical score (CS) based on four clinical parameters (respiratory distress, cough episodes, cough frequency, tracheal sensitivity) was monitored at the hospital (enrolment and weeks 2 and 4). Water intake, urination habits, and adherence and tolerance to treatments were monitored weekly. Significant improvements in clinical parameters were identified in both groups throughout the study. Between-group (OG-IG) comparisons revealed no significant differences, indicating equivalent improvement. At the study's endpoint, the IG dogs had a significantly lower CS (5.69 ± 0.79) than OG dogs (6.43 ± 1.02, p < 0.05). Adherence and tolerance were comparable. From weeks 2 to 4, OG dogs were significantly thirstier and urinated more frequently than IG dogs. In conclusion, fluticasone provided good tolerability and efficacy in controlling cough in dogs with TC, and they showed a lower incidence of signs of hypercortisolism compared to prednisone. These data encourage the use of inhaled fluticasone in dogs with cough and TC.

Recovery of hypoglycemic confidence using intermittently scanned continuous glucose monitoring among adults with type 1 diabetes with level 3 hypoglycemia: A prospective, single-center, single-arm study.

AIM: To investigate whether the FreeStyle Libre, an intermittent scanning continuous glucose monitoring (isCGM) system, influences confidence in managing hypoglycemia in adults with type 1 diabetes. MATERIALS AND METHODS: This longitudinal, observational study conducted at one facility included 121 adults with type 1 diabetes. Participants used the conventional finger-prick method for self-testing glucose before using isCGM. At baseline and 12 months after initiating isCGM, the Hypoglycemic Confidence Scale (HCS), Diabetes Treatment Satisfaction Questionnaire (DTSQ), and HbA1c were performed. At 12 months, the percentage of individuals utilizing isCGM trend arrows for glucose management was observed. The primary endpoint was hypoglycemic confidence change attributed to using isCGM. RESULTS: After using isCGM, HCS scores improved significantly from 2.89 (2.56, 3.22) to 3.00 (2.20, 3.33) (p < 0.001); median (25%, 75%). Among participants with level 3 hypoglycemia at baseline, hypoglycemic confidence during sleep (p < 0.05), in social situations (p < 0.05), and in avoiding serious hypoglycemia-related problems (p < 0.05) were improved. Despite hypoglycemia risk, participants could continue daily activities by using isCGM (p < 0.05), and sixty-nine percent utilized trend arrows effectively. CONCLUSION: Using isCGM improved hypoglycemic confidence among adults with type 1 diabetes. Data analysis indicated that people with type 1 diabetes could live more freely and better manage hypoglycemia using isCGM.
