A new herbal anesthetic agent for common carp (Cyprinus carpio) sedation and anesthesia: nutmeg (Myristica fragrans) essential oil.

In aquaculture, interest in natural essential oils is increasing alongside synthetic anesthetic agents. In this context, the anesthetic efficacy of nutmeg essential oil, which had not been previously tested, was investigated in common carp (Cyprinus carpio). The study, conducted using three different concentrations (800 μL/L "LC", 1,200 μL/L "MC", and 1,400 μL/L "HC"), found that induction times were <3 min for MC and HC, while LC had a longer induction time, exceeding acceptable levels. Within the first 4 h, white blood cells, red blood cells, hemoglobin, and hematocrit levels increased to >5 103/μL, >1 106/μL, >6 g/dL, and >12%, respectively. However, they returned to control levels after 8 h. Histological signs were more severe with higher concentrations, and necrosis was only observed in the HC group. Alkaline comet assay results showed DNA migration only in the HC group. According to the PROMETHEE multi-criteria decision-making model, the LC concentration is suitable for sedation, while the MC concentration should be used for deep anesthesia. The current study demonstrates that nutmeg essential oil can be used as an alternative to commercial synthetic anesthetic agents.

Impact of Co-Management Mode on Diagnosis and Treatment Compliance in Community-Level Diabetic Patients with Retinopathy.

Aims/Background To implement a co-management mode among community-level diabetes patients and analyze its impact on diagnosis and treatment compliance and diabetic retinopathy of the patients. Methods A total of 80 patients who underwent diabetic retinopathy examination in Lanxi People's Hospital from January 2021 to March 2022 were retrospectively selected as the study objects. The clinical data of the patients were analyzed, including 40 patients who adopted the conventional diabetes management mode from January 2021 to August 2021 as the control group. From September 2021 to March 2022, 40 patients in the county medical service community diabetes management team model were adopted as the management group. The two groups of patients were compared in terms of diabetic retinopathy indictors, biochemical examination indicators, self-management ability, and nursing management satisfaction. Results Number of patients complying with treatment protocols in the management group was higher than that in the control group (p < 0.05). The blood spot area, macular thickness, hemangioma volume, and visual-field grayscale value in the management group at the last follow-up were all lower than those in the control group (p < 0.05). The levels of diastolic blood pressure (DBP), systolic blood pressure (SBP), fasting blood glucose (FBG), hemoglobin A1C (HbA1c), total cholesterol (TC), and triglyceride (TG) in the management group at the last follow-up were all lower than those in the control group (p < 0.05). The scores of disease cognition ability, self-management ability, and nursing management satisfaction in the management group were all higher than those in the control group (p < 0.05). Conclusion By changing management concept and implementing the whole-process management and treatment mode for diabetic patients within the scope of the county medical service community, the diagnosis and treatment compliance of the patients can be improved, and the effective control of blood glucose, blood pressure, and blood lipid levels can be achieved, thereby improving the self-management ability and nursing management satisfaction of the patients and providing a new nursing mode for chronic disease management.

Investigating the protective effects of epigallocatechin-gallate against polystyrene microplastics-induced biochemical and hematological alterations in rats

BackgroundPolystyrene microplastics (PS-MPs) are widely used and found in drinking water and food, concerns have been raised about their potential health effects, especially in causing oxidative stress and inflammation in living organisms. ObjectivesThe aim of this study was to investigate the protective effects of epigallocatechin-gallate (EGCG), a natural antioxidant and anti-inflammatory compound, against PS-MPs-induced biochemical and hematological alterations in rats. MethodsMale Wistar rats were divided into four groups: control, EGCG-treated (80 mg∙ kg-1/d), PS-MPs-exposed (0.01 mg∙kg-1/d), and PS-MPs+EGCG-treated groups. PS-MPs were orally administered for 56 days, while EGCG was given concomitantly by gavage. At the end of the treatment period, blood samples were collected for hematological and biochemical analyses. Oxido-nitrergic stress markers, including malondialdehyde (MDA), nitric oxide (NO), reactive nitrogen species (RONS) and reduced glutathione (GSH), Superoxide dismutase (SOD), catalase (CAT), as well as inflammatory markers, such as tumor necrosis factor alpha (TNF-α), interferon gamma (IFY-γ) and interleukin-10 (IL-10), were also measured in serum. ResultsTreatment with PS-MPs caused a significant increase in MDA, RONS, NO levels and a decrease in SOD, CAT and GSH levels, indicating the induction of oxido-nitrergic stress. PS-MPs also caused an increase in the levels of TNF-α, IFY-γ, MPO and decreased IL-10, indicating the induction of inflammation. Additionally, PS-MPs caused alterations in hematological and serum transaminase parameters, including a decrease in red blood cell count, hemoglobin, and hematocrit levels, neutrophil and eaosinophil and an increase in white blood cell count, lymphocyte count, AST, ALT, ALP, LDH and GGT. PS-MPs also caused disturbances in electrolyte balance and renal function markers. However, treatment with EGCG significantly attenuated these alterations induced by PS-MPs, indicating its protective effects. ConclusionThe results of this study demonstrate that EGCG can protect against PS-MPs-induced biochemical and hematological alterations in rats, possibly through its antioxidant and anti-inflammatory properties.

Clinical implications and pharmacological considerations of glycemic variability in patients with type 2 diabetes mellitus

Glycemic variability (GV), independently of glycemic control, has emerged as a prognostic marker in patients with type 2 diabetes mellitus (DM). In this study, we assessed the prognostic value of long-term GV for predicting major adverse cardiovascular events (MACE) in our local population. We also assessed its prognostic value for diabetic microvascular complications (DMC) and its relationships with antidiabetic medications. This was a retrospective cohort study that recruited 680 patients with type 2 DM across 2015–2017. MACE were defined as: the composite of; total death, myocardial infarction (MI), stroke, hospitalization due to heart failure, and revascularization. GV was calculated for two glycemic control markers: glycated hemoglobin (G-Hb) and fasting blood sugar (FBS); via three metrics- standard deviation (SD), coefficient of variation (CV), and variability independent from the mean (VIM). Cox proportional hazard models and Kruskal-Wallis tests were used in the statistical analysis. 105 events classified as MACE were identified in 86 patients and 104 DMC in 98 patients in an average follow-up period of 78.43 months. Long-term GV was found to be an independent predictor of MACE, particularly for FBS-CV but not a predictor of DMC. FBS-CV ≥ 17.51% as compared with < 17.51% was a significant and independent predictor of MACE, with HR 1.589 (95% CI; 1.022, 2.472) (P = 0.040). DMC were predicted mainly by the duration of type 2 DM, and by the glycemic control; similarly represented by G-Hb and FBS. Patients on metformin, and dipeptidyl peptidase (DPP) 4 inhibitors, had the lowest GV, as compared with patients whose treatments included insulin/sulphonylureas (P < 0.001). In our population, long-term GV predicted MACE: with FBS-CV superior to the “gold standard” glycemic control marker G-Hb. Further, GV may be explained, partially at least, by the choice of antidiabetic medications: this finding might contribute to the cardiovascular protection attributed to one class rather than another.

Baseline level of interleukin-6 is associated with the risk of acute coronary syndrome development in SARS-CoV‐2 infection

BackgroundAcute coronary syndrome (ACS) is frequently reported in patients with coronavirus disease 2019 (COVID-19). Cytokine storm induced by interleukin-6 (IL-6) has been suggested to potentially cause myocardial injury in COVID-19. We investigated the association between baseline level of IL-6 and development of ACS in COVID-19 patients.MethodsDemographic and clinical data of hospitalized COVID-19 patients from 2020 to 2022 were reviewed. Extracted data including patient characteristics, laboratory biomarkers, and systemic inflammation indexes in patients with or without ACS were reviewed and analyzed. Logistic regression models were applied to analyze predictors of ACS development and receiver-operating characteristic (ROC) curves were used to assess discriminatory power of IL-6 and other risk factors for predicting ACS development.ResultsAmong 1,753 COVID-19 patients, 37 cases experienced ACS and 159 patients without main COVID-19 complications were randomly selected as controls. ACS patients were older (p = 0.001) and suffered from more comorbidities including diabetes (43% vs. 18%, p = 0.001), hypertension (40.5% vs. 24.5%, p = 0.050), ischemic heart disease (49% vs. 9%, p = 0.001), and hyperlipidemia (19% vs. 5%, p = 0.010). Also, decreased level of consciousness (31.6% vs. 2.5%, p = 0.001), ICU admission (65% vs. 2%, p = 0.001), and mortality events (70% vs. 0.6%, p = 0.001) were more prevalent in the ACS group. Baseline levels of IL-6 (p = 0.001), D-dimer (p = 0.026), troponin (p = 0.001), blood urea nitrogen (p = 0.002), and creatinine (p = 0.008) were higher in ACS patients but erythrocyte sedimentation rate (p = 0.013), hemoglobin (p = 0.033), and red blood cells (p = 0.028) were lower compared with controls. Also, age (OR: 1.06, p = 0.019), IL-6 (OR: 1.44, p = 0.047), and cardiovascular disease (CVD) (OR: 3.66, p = 0.043) were associated with ACS development. The area under the curve (AUC) of IL-6 and combined predictors respectively was 0.661 (p = 0.002) and 0.829 (p = 0.001).ConclusionsHigh IL-6 concentration at baseline is a strong predictor for ACS development in COVID-19 patients. Also, elderly and concurrent CVD are significantly associated with ACS development.

Complex therapy of mineral metabolism in service dogs

The high physical and functional load of service dogs causes changes not only in body systems, but also in metabolism as a whole. An integrated approach to the study of this problem and the search for a pharmacotherapeutic solution will allow us to correct biochemical changes in the body of dogs and improve the performance and quality of life of animals. The purpose of the study was to study the therapeutic effectiveness of a complex of metabolic stimulants for the correction of mineral metabolism. For the study, 16 service dogs were selected in the area of application of the general search profile, belonging to the Ministry of Internal Affairs of Russia in the Altai Territory. Blood was drawn at the beginning and end of the study to analyze red blood cell counts, hemoglobin, hematocrit, glucose, cholesterol, triglycerides, iron, magnesium, zinc, calcium, phosphorus, and chloride. According to the results of the study, it was established that a violation of homeostasis in service dogs was accompanied by changes in some indicators of red blood, as well as pathology of mineral metabolism. After a course of pharmacotherapy, an increase in red blood cells (up to 7.9±0.22*×1012 cells/l) and hemoglobin (up to 141.66±7.32 g/l) was observed in dogs. Carbohydrate metabolism in both groups was characterized by hypoglycemia (3.34±0.21–3.43±0.28 mmol/l). By the end of the study, the glucose level in the experimental group significantly increased by 31.4% relative to the animals in the control group. By the end of the study, cholesterol levels in dogs in the experimental group decreased more rapidly compared to the control group. The study of the dynamics of mineral metabolism indicators revealed a significant increase in iron levels in the experimental group of animals (up to 25.3±1.9 µmol/l), which was 22.8% higher than the control value. Changes in other indicators of mineral metabolism did not differ significantly between the groups, although dogs receiving stimulating therapy showed positive dynamics of changes in mineral metabolism indicators. The use of a complex of metabolic stimulants “Suiferrovita”, “Strolitin”, “Amber Acid” stabilized red blood counts and contributed to the development of a tendency towards the restoration of mineral metabolism.

AVERAGE LINKAGE CLUSTERING METHOD AND MOLECULAR DOCKING STUDY ON DATE PALM (PHOENIX DACTYLIFERA L.) AS POTENTIAL ANTI-ANEMIA AGENT

Anemia, characterized by blood hemoglobin (Hb) levels below the World Health Organization's (WHO) normal limit, remains a significant health concern. Date fruit (Phoenix dactylifera L.) stands out as an herbal plant boasting the highest iron content at 13.7 mg, suggesting its potential as an anti-anemia agent. This study aimed to explore the anti-anemia potential of active compounds in date fruit using average linkage clustering and validated using molecular docking. Compounds from dates were gathered via GC-MS analysis and online databases, totaling 145 compounds—50 from GC-MS and 95 from Knapsack and Dr. Duke databases. Additionally, 5 lead compounds served as positive controls for comparison. SwissADME online servers assessed the compounds' properties, serving as materials for the clustering method. The average linkage clustering method was employed, yielding an excellent dendrogram with a cophenetic correlation of 0.711. Notably, a total of 17 date fruit compounds are in the same cluster as the lead compounds. Molecular docking revealed 4 date palm fruit-derived compounds as potential PHD enzyme inhibitors, promising for anemia treatment. In conclusion, the average linkage clustering method and validation using molecular docking approaches highlight date fruit's potential as an alternative anemia treatment, showcasing the significance of interdisciplinary methodologies in drug discovery.

Marine macroalgae Chaetomorpha aerea as a dietary supplement: Optimizing immunity and resistance to Edwardsiella tarda in tilapia (Oreochromis mossambicus)

The intensification of aquaculture has led to a rise in fish infections, necessitating the search for alternative antibiotics. In this context, our study investigated the effects of dietary supplementation with Chaetomorpha aerea, a filamentous green algae, on the immune health and resistance to infections in tilapia (Oreochromis mossambicus). Diets containing varying concentrations of C. aerea (0, 1, 2, 5, and 10 g/kg) were prepared and administered to the fish for 30 days, followed by a challenge with Edwardsiella tarda to evaluate survival rates. The results were significant. The diet containing 5 g/kg of C. aerea (group T3) brought about substantial improvements in hematological parameters, including increases in red blood cell count (RBC), hematocrit (Hct), and hemoglobin (Hb). The T3 group exhibited a robust immune response, with higher lysozyme and ceruloplasmin activity in immunological assays. LBP gene expression was significantly elevated in the spleen and thymus of fish in the T3 group, which correlated with higher survival after bacterial challenge compared to the control group. Principal Component Analysis (PCA) and cluster analysis confirmed that the 5 g/kg concentration stood out for maximizing immunological benefits without compromising the overall health of the fish. These findings highlight the robust immune response in the T3 group, a key finding of our study. We conclude that supplementation with C. aerea represents a promising and sustainable alternative in the formulation of diets for tilapia, contributing to improved health and resistance to diseases. Future studies are recommended to explore its application in other species and development stages, in addition to evaluating other health biomarkers.

Analysis of five Chinese individuals with rare thalassemia mutation HBB: c.93-21G＞A

To explore the hematological phenotype and genotypic characteristics of five Chinese individuals with a rare thalassemia mutation HBB: c.93-21G＞A. A retrospective study was carried out on five individuals identified by the People's Hospital of Yangjiang and Guangzhou Hybribio Co., Ltd. from May 2018 to September 2022. Routine blood test and hemoglobin electrophoresis were performed, and the genotypes of five subjects were determined by using PCR combined with reverse dot blotting (RDB), nested PCR, Gap-PCR and Sanger sequencing. This study was approved by the People's Hospital of Yangjiang (Ethics No. 20240001). Among the five individuals, hematological data of one was unavailable, and the remaining four had presented with microcytosis and hypochromia. The results of hemoglobin electrophoresis indicated that all of them had a HbA2 level of ≥4.7%. Genetic analysis showed that one case had harbored compound heterozygous mutations of αααanti3.7 triplet and HBB: c.93-21G＞A, one had compound heterozygous mutations of -α3.7 and HBB: c.93-21G＞A, whilst the remaining three were heterozygous for the HBB: c.93-21G＞A mutation. The hematological phenotype of β-thalassemia carriers (HBB: c.93-21G＞A) is similar to that of other β+ thalassemia heterozygotes with mild β-thalassemia characteristics.

Influence of meteorological factors on intraocular pressure variability using a large-scale cohort

The effects of meteorological conditions on IOP using a large-scale health examination cohort were investigated. There were a total of 811,854 measurements from 126,630 eyes of 63,839 subjects in 9 years from a health checkup cohort followed up annually for age, sex, body height, body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), and IOP. The effects of these variables and the meteorological data of daily average temperature (TP), daily average local atmospheric pressure (AP), daily average volumetric humidity (VH), and daily amount of rainfall (RF) on the day of IOP measurement on IOP were investigated. Several variables were significantly associated with IOP, including sex, age, body height, BMI, SBP, DBP, average TP, average AP, average VH, RF, white blood cell count, red blood cell count, hemoglobin, aspartate aminotransferase, alanine aminotransferase, guanosine triphosphate, calcium, and HbA1c. This study indicated a correlation between meteorological factors and IOP. Higher AP and RF were associated with elevated IOP, whereas higher TP and VH were associated with decreased IOP.

Probiotic Strain Lactobacillus plantarum GCLP4 Derived From the Gut of Ctenopharyngodon idella Modulates Growth, Digestive Enzymes and Immune-Biochemical Parameters of Labeo rohita Fingerlings.

The present study was carried out to isolate, identify, and characterize bacterial probiotic strain from the gut of Ctenopharyngodon idella (Grass carp) and then to study its effect on growth, digestive enzymes and immunity of Labeo rohita fingerlings. A total of 6 gram-positive bacteria belonging to the genus Lactobacillus spp. (3), Bacillus spp. (2) and Staphylococcus spp. (1), were identified biochemically. Based on the biochemical results, the isolate GCLP4 was selected for molecular confirmation and BLAST analysis showed maximum homology with Lactobacillus plantarum (100% ident). Fish were fed for 60 days with diet containing 0 (T0), 105 (T1), 107 (T2), 109 (T3) cfu/g diet of L. plantarum GCLP4 and 105 (T4) of commercial probiotics. Results shows that supplementation of GCLP4 had significantly (p < 0.05) improve weight gain (%), specific growth rate (SGR) and feed conversion ratio (FCR) of L. rohita with better values in T3 group. The immunological parameters (white blood cell, red blood cell, haemoglobin, total protein, albumin and globulin were significantly higher (p < 0.05) with 107 and 109 Lactobacillus GCLP4 cfu/g diet. The digestive enzyme activities (protease, amylase and lipase) were significantly (p < 0.05) higher, particularly, with 109 Lactobacillus GCLP4 cfu/g of diet. All the groups supplemented with GCLP4 including the commercial probiotics have lower (p < 0.05) activities of serum transaminase enzymes along with lower (p < 0.005) level of glucose as compared to the control group. The results of the study collectively suggest that dietary L. plantarum GCLP4 at 109 cfu/g is an effective probiotic obtained from grass carp having potency to promote growth, digestive enzymes and immune-biochemical indices of L. rohita fingerlings in present culture condition.

Assessing the Influence of Long-Term Gender-Affirming Hormone Therapy on Cardiovascular Risk in Transgender Men through Carotid Intima-Media Thickness.

Background: Transgender men use exogenous androgen for male pattern virilization. Hysterectomy and bilateral salpingo-oophorectomy (HBSO) is performed to stop the endogenous estrogen secretion. Cardiovascular disease (CVD) risk has been shown to increase with long-term use of androgens and the removal of estrogen. We aimed to investigate the CVD risk in these individuals by measuring internal and common carotid artery intima-media thicknesses (CIMT). Methods: In this cohort study, data were collected from transgender men who had undergone HBSO and used androgens for at least two years (median treatment duration was 5 years in our research). Cisgender women in the same age range were selected as the control group. Demographics, vital signs, and hematological values of transgender patients and cisgender women subjects in the control group were noted. CVD markers were compared with sonographically measured CIMT values. Results: The mean age and body mass index (BMI) of the study group were 32.6 and 25.3, respectively. Weight, systolic-diastolic blood pressure, hemoglobin, hematocrit, low-density lipoprotein (LDL), serum triglyceride (TG), HbA1c levels, internal CIMT, and common CIMT values of the study group were higher, while the high-density lipoprotein (HDL) level was significantly lower compared the control group (p1 = 0.025, p2 = 0.010, p3 = 0.002, p4 = 0.001, p5 = 0.001, p6 = 0.012, p7 = 0.008, p8 = 0.007, p9 = 0.013, and p10 = 0.001). There was also an increase in the body weight, BMI, LDL, and TG levels of the study group after the testosterone treatment (p1 = 0.025, p2 = 0.019, p3 = 0.001, p4 = 0.001, and p5 = 0.001). Conclusions: We demonstrated that the use of testosterone therapy in transgender men is associated with higher CIMT values. While further investigation is needed to assess morbidity and mortality rates, we recommend that regular clinical and radiological examinations be performed in these individuals to accurately evaluate the risk of CVD.

Effect of pharmacist interventions in chronic kidney disease: a meta-analysis.

Pharmacists are uniquely placed with their therapeutic knowledge to manage people with chronic kidney disease (CKD). Data is limited regarding the impact of pharmacist interventions on economic, clinical, and humanistic outcomes (ECHO). A systematic review and meta-analysis of randomized controlled trials (RCTs) of interventions with pharmacist input was conducted, which included adults with a diagnosis of CKD, including those with and without kidney replacement therapy. Data was extracted on ECHO: economic (e.g. healthcare-associated costs), clinical (e.g. mortality), and humanistic (e.g. patient satisfaction) outcomes. Where appropriate, a random-effects model meta-analysis generated a pooled estimate of effect. A direction of effect plot was used to summarize the overall effects for clinical outcome domains. 32 RCTs reported a total of 10 economic, 211 clinical, and 18 humanistic outcomes. Pharmacist interventions resulted in statistically significant improvements in systolic blood pressure and hemoglobin levels, but not in diastolic blood pressure, estimated glomerular filtration rate, creatinine, and low-density lipoprotein cholesterol levels. Mixed findings were reported for clinical and economic outcomes, whilst pharmacist interventions resulted in an improvement in humanistic outcomes such as patient satisfaction and patient knowledge. Findings showed pharmacist interventions had mixed results for various outcomes. Future studies should be more robustly designed and take into consideration the role of the pharmacist in prescribing and deprescribing, the findings of which will help inform research and clinical practice.

Effects of 60 degrees of flexion and perioperative use of tranexamic acid on recovery after knee replacement

Abstract OBJECTIVE To explore the effect of 60 knee flexion combined with multiple tranexamic acid application on postoperative recovery of knee replacement patients. METHODS Knee replacement patients admitted to our hospital from October 2020 to September 2022 were selected as the study subjects, and randomly divided into two groups. Postoperative D-dimer, prothrombin time and partial thrombin time were recorded in the two groups, and the differences between the two groups were compared. Erythrocyte, hemoglobin and erythrocyte volume were recorded before, 1 day and 3 days after surgery and the affected limb circumference were also assessed. RESULTS On the 1st and 3rd day after surgery, the red blood cells, hemoglobin, and hematocrit levels in the experimental group were higher than those in the control group, and the differences were statistically significant(P&amp;lt;0.05). The difference in VAS score and circumference between the two groups on the 1st day and 3rd day after surgery was compared, and the difference was statistically significant. The difference in VAS score and circumference was lower in the control group(P&amp;lt;0.05). After surgical treatment, knee joint function recovered, knee joint mobility and HSS score improved, and the difference between the experimental groups was statistically significant (P&amp;lt;0.05). CONCLUSION Perioperative 60-degree flexion combined with multiple tranexamic acids can significantly reduce blood loss in patients undergoing knee replacement surgery, increase red blood cells, hemoglobin levels and red blood cell volume on postoperative days 1 and 3, and reduce postoperative swelling of the affected limb.

Lysine (K)-specific methyltransferase 2A (KMT2A) rearrangements among Iraqi de novo acute myeloid leukemia

Abstract: BACKGROUND: The classification of acute myeloid leukemia (AML) has evolved extensively over the last 20 years significantly, impacting the diagnosis and prognosis of the patients. The lysine (K)-specific methyltransferase 2A (KMT2A) gene, which has more than 80 gene fusions, is present in approximately 10% of all leukemias. Most KMT2A rearrangements are associated with adverse prognosis and need heavy chemotherapy protocol upfront. OBJECTIVE: This study aims to study the prevalence of KMT2A gene fusion among Iraqi patients with AML and its association with clinical and hematological parameters and patients’ outcomes. PATIENTS, MATERIALS, AND METHODS: A prospective cohort study conducted between December 2020 and May 2022 enrolled 115 Iraqi adults newly diagnosed with AML at the Hematology Unit of Baghdad Teaching Hospital. The patients were also monitored at this facility during the study period. Genetic rearrangements were detected using the Leukemia Q-Fusion Screening Kit through Real-Time Quantitative Reverse Transcription PCR (RT-qPCR) analysis. RESULTS: KMT2A rearrangements were identified in 23 (20%) patients. The most common was t(10;11) which presented in 15 (13%) patients, followed by t(9;11) in 5 (4.3%) patients and t(11;17) in 3 (2.6%) patients. Patients with KMT2A rearrangements were significantly older and more likely to have splenomegaly. At 1-month posttreatment, they had significantly lower red blood cell counts and hemoglobin levels and higher blast percentages. Only 4.3% achieved complete remission (CR) compared to 76.1% without KMT2A rearrangements, with a significantly higher mortality rate (30.4% vs. 5.4%, P = 0.0001). Regarding the treatment response, no significant differences were observed among the different fusion types of KMT2A rearrangements. CONCLUSION: KMT2A rearrangements are more prevalent among Iraqi AML patients compared to the global trend and are associated with older age, higher rates of splenomegaly, poorer hematological recovery, and worse outcomes, regardless of the KMT2A rearrangement fusion type.

Improving nutrient digestibility and health in rabbits: effect of fermented rapeseed meal supplementation on haematological and lipid parameters of blood

BackgroundMany studies conducted on livestock point to fermented rapeseed meal (FRSM) as a component that provides adequate quality and quantity of protein. Additionally, it is a very good source of probiotics, prebiotics, enzymes, and antioxidants. A study was undertaken to assess the impact of a feed supplemented with FRSM fermented with Bacillus subtilis strain 87Y on production parameters, nutrient digestibility, and haematological and lipid indicators of the blood in growing rabbits. Forty New Zealand White rabbits (body weight 816,25 ± 24,98 g) aged 35 days were used in this study. The animals were divided into four groups, a control group (C) was fed a standard diet, while in the diet of three experimental groups, soybean meal (SBM) was replaced with FRSM at 4% (FR4 group), 8% (FR8 group), or 12% (FR12 group).ResultsDetailed analysis revealed that the contribution of FRSM in the rabbit feed, regardless of the amount, had a significant effect on body weight gain (BWG), as well as average daily gain (ADG), compared to the control group (C), (P = 0.017). All groups receiving FRSM had a significantly lower (P = 0.05) feed conversion ratio (FCR) compared to the control group. In rabbits fed a diet containing 8% FRSM, the blood haematological parameters, such as red blood cells (RBC), haematocrit (HCT), haemoglobin (HGB), and mean corpuscular volume (MCV), were significantly higher compared to the control group (P = 0.037). In addition, a significant reduction in the plasma levels of the low-density lipoprotein fraction (LDL-chol), the ratio of total cholesterol to high-density lipoprotein (CHOL/HDL), (P = 0.001), and triacylglycerols (TG), (P = 0.004) were observed in the experimental groups compared to the control group.ConclusionsBased on the encouraging outcomes, it is possible to recommend domestically produced FRSM as a viable substitute for genetically-modified (GM) SBM in rabbit feed.

Combined Diabetes Education/Skills Training and Social Needs Resolution Intervention for Older African Americans with Poorly Controlled Type 2 Diabetes (DM Social Needs): Study Protocol for a Randomized Controlled Trial.

Approximately 11.3% of the US population has diabetes. The burden of diabetes is higher in older adults and African Americans (AAs), such that 40% of adults aged 50 years and older have diabetes; African Americans are 60% more likely to be diagnosed with diabetes compared to non-Hispanic Whites (NHWs). Structural racism has resulted in fewer economic and educational opportunities for AAs, higher social risks, and unmet basic needs, which result in financial instability, housing instability, food insecurity, and a lack of transportation compared to NHWs. The presence of these unmet basic needs is a driver of poor adherence to diabetes self-management in older AAs. To test the preliminary efficacy of a nurse case-manager, telephone-delivered intervention that provides foundational diabetes self-management education and skills training, while also addressing and resolving the unmet social needs of older AAs with poorly controlled type 2 diabetes mellitus (T2DM). The primary hypothesis is that older AAs with T2DM randomized to the DM Social Needs intervention will have significantly lower hemoglobin A1C (HbA1C), blood pressure, and LDL levels compared to the usual care arm at 6 months post randomization. This is a three-year prospective, randomized clinical trial that will enroll 100 AAs aged 50 and older with type 2 diabetes (T2DM) and HbA1C ≥ 8% into one of the following two groups: (1) a nurse case-manager, telephone-delivered intervention that provides foundational diabetes self-management education and skills training, but also addresses and resolves unmet social needs; or (2) an enhanced usual care group that will receive mailed diabetes education materials. Participants will be followed for 6 months to determine the effect of the intervention on HbA1C, blood pressure, and low-density lipoprotein (LDL) cholesterol levels. Baseline characteristics will be presented by study group, and within- and between-group changes in primary outcomes from baseline to 6 months will be reported. The results from this study will provide insights into the efficacy of a combined diabetes education and skills training and social needs resolution intervention for older African Americans with poorly controlled type 2 diabetes and will inform strategies to improve diabetes outcomes for this vulnerable population.

6602 Classification of TSH Trajectories During Levothyroxine Treatment in the ELSA-Brasil Cohort

Abstract Disclosure: M.D. Ettleson: None. G.C. Penna: Consulting Fee; Self; Ipsen, Bayer, Inc.. W. Wan: None. I.M. Bensenor: None. N. Laiteerapong: None. A.C. Bianco: Consulting Fee; Self; Abbvie. Classification of TSH Trajectories During Levothyroxine Treatment in the ELSA-Brasil Cohort Introduction: Hypothyroidism is a common endocrine disorder for which levothyroxine (LT4) serves as the primary treatment. Periods during which thyroid stimulating hormone (TSH) levels are outside the normal range have been associated with adverse cardiovascular outcomes, including mortality. In practice, serial TSH levels are measured over time to ensure therapeutic LT4 treatment is maintained. However, there is no measure of the quality of treatment maintenance over time. TSH trajectory classification represents a novel approach to define the adequacy of LT4 treatment for hypothyroidism over time utilizing multiple observation points. Methods: With longitudinal clinical data, including thyroid function from a large prospective study, we aimed to define classes of TSH trajectories and examine changes in cardiovascular (CV) health markers over a 9 year study period with three observation points. Growth mixture modeling (GMM), including latent class growth analysis (LCGA), was used to classify LT4-treated individuals participating in the Longitudinal Study of Adult Health in Brazil (ELSA-Brasil) based on serial TSH levels. Repeated measure analyses were then utilized to measure within-class changes in blood pressure, lipid levels, hemoglobin A1c, and CV-related medication utilization. Results: From the 621 LT4-treated study participants, the best-fit GMM approach identified four TSH trajectory classes, as defined by their relationship to the normal TSH range: 1) High-high normal TSH, 2) Normal TSH, 3) Normal-to-low TSH, and 4) Low-to-normal TSH. Notably, the average baseline LT4 dose was lowest in the high-high normal TSH group (77.7 mcg, p &amp;lt;0.001). There were no significant differences in CV health markers between the classes at baseline. At least one significant difference in CV markers occurred in all classes, highlighted by the low-to-normal class, in which total and HDL cholesterol, triglycerides, and A1c all increased significantly (p = 0.049, p &amp;lt;0.001, p &amp;lt;0.001, and p = 0.001, respectively). Medication utilization increased in all classes over the study period. Conclusion: GMM/LCGA represents a viable approach to define and examine LT4 treatment by TSH trajectory. In the future, more comprehensive datasets will allow for more complex trajectory modeling and analysis of clinical outcome differences between trajectory classes. Defining the adequacy of LT4 treatment using a longitudinal scope could allow clinicians to more accurately communicate treatment progress and identify patients at risk for adverse CV outcomes.

Objective Prior studies suggest that higher preconception triglycerides are associated with higher infant birthweight in people without pre-existing diabetes. People with pre-existing diabetes have high risk for dyslipidemia and large for gestational age (LGA) neonates; however, data is scarce on the association between preconception lipids and pregnancy outcomes in this population. Methods: We retrospectively analyzed pregnancies with pre-existing diabetes who had triglyceride levels available prior to conception. We used generalized estimating equations (GEE) for linear regression to examine the association of preconception log-transformed triglycerides with birthweight percentile (primary outcome) while accounting for pregnancies that occurred in the same person. We used logistic regression via GEE for other pregnancy outcomes, including LGA. We built unadjusted models and models adjusted for maternal age, race/ethnicity, parity, insurance status, marital status, first trimester blood pressure, and BMI and hemoglobin A1C at 12 weeks’ gestation. We assessed for effect modification by diabetes type via stratification and interaction models. Results: Among 217 pregnancies in 189 people, 27% had preconception triglycerides ≥150 mg/dL and 32% resulted in LGA infants. Log-transformed triglycerides were not significantly associated with birthweight percentile in the full cohort in either adjusted (P = 0.62) or unadjusted models (P = 0.35). However, in unadjusted analyses stratified by diabetes type, a one unit increase in log-transformed triglycerides was associated with a 10.4 percentile increase in birthweight in pregnancies with type 2 diabetes (T2D; N=137) (95% confidence interval [CI] [1.12, 19.63], P = 0.03) and a 16.0 percentile decrease in birthweight in those with type 1 diabetes (T1D; N=76) (95% CI [-30.03, -1.95], P = 0.03). These associations were significantly different from each other (P for interaction = 0.002). Associations were attenuated after multivariate adjustment (T2D: β = 6.62, 95% CI [-3.42, 16.66], P= 0.20; T1D: β = -11.12, 95% CI [-23.61, 1.37], P= 0.08). Analyses of LGA incidence were consistent with primary findings, as those with T2D and higher log-transformed triglyceride levels were more likely to have LGA infants (odds ratio [OR] = 3.84, 95% CI [1.71, 8.62], P= 0.001) while an inverse association was seen in T1D (OR = 0.35, 95% CI [0.13, 0.94], P= 0.04). After multivariate adjustment, the association with LGA persisted in T2D (OR = 4.03, 95% CI [1.42, 11.44], P= 0.01) but was attenuated in T1D (OR = 0.34, 95% CI [0.09, 1.27], P= 0.11). Conclusion: Higher preconception triglycerides are associated with higher infant birthweight in people with T2D, while the inverse may be seen in those with T1D. Mechanisms linking preconception triglycerides and birthweight in people with diabetes should be examined in future studies. Presentation: 6/2/2024

7490 Comparative Clinical Analysis of DPP-4 inhibitors and SGLT2 inhibitors; Switch Study in Real-World Setting

Abstract Disclosure: H. Choe: None. M. Kwak: None. J. Lee: None. Y. Choi: None. E. Hong: None. Objective: Dipeptidyl peptidase-4 inhibitors (DPP-4i) and sodium-glucose cotransporter-2 inhibitors (SGLT2i) represent two distinct pharmacological pathways in the management of type 2 diabetes, both aiming to improve glycemic control without risk of hypoglycemia. Metabolic implications and glycemic control associated with the interchange between SGLT2i and DPP-4i are scarce. This study aimed to evaluate the effect of switching between SGLT2i and DPP4i on various clinical parameters in Korean patients with type 2 diabetes. Methods: We conducted a retrospective cohort study at Hallym University Dongtan Sacred Heart Hospital, using clinical data warehouse. Baseline measurements and follow-up data at 3 months were collected for parameters including hemoglobin A1c (HbA1c), blood pressure, lipid profile, liver enzymes, renal function, and other metabolic markers. Results: Between 2015 and 2023, 104 participants switched from SGLT2 inhibitors to DPP4 inhibitors, while 321 switched in the opposite direction. Initially, those who switched from SGLT2 inhibitors to DPP4 inhibitors presented with lower baseline HbA1c levels (7.22 ± 0.73% versus 7.42 ± 0.76%, P = 0.017) and higher estimated glomerular filtration rates (eGFR) (95.2 ± 23.1 versus 85.9 ± 23.7 mL/min/1.73m², P = 0.001) compared to those who switched from DPP4 inhibitors to SGLT2 inhibitors. At three months of follow-up, the SGLT2 inhibitors to DPP4 inhibitors group exhibited a more significant reduction in HbA1c (adjusted β 0.22, 95% CI 0.03 to 0.40, P = 0.023), especially in patients with reduced eGFR (&amp;lt;60 mL/min/1.73 m²) (β 1.2, 95% CI 0.30 to 2.11, P = 0.013; P for interaction = 0.005). On the other hand, the DPP4 inhibitors to SGLT2 inhibitors group showed a greater decrease in fasting glucose levels (β -9.73, 95% CI -17.6 to -1.86, P = 0.016), along with more pronounced reductions in liver enzymes AST (β -4.15, 95% CI -6.49 to -1.81, P &amp;lt; 0.001) and ALT (β -6.42, 95% CI -9.58 to -3.27, P &amp;lt; 0.001), and a significant increase in hematocrit (β 3.31, 95% CI 2.36 to 4.26, P &amp;lt; 0.001) compared to the initial group. Conclusions: The study concludes that in Korean patients with type 2 diabetes, switching from SGLT2 inhibitors to DPP4 inhibitors is associated with a greater reduction in HbA1c, particularly in those with reduced renal function. Conversely, switching from DPP4 inhibitors to SGLT2 inhibitors results in more substantial improvements in fasting glucose and liver enzyme levels, suggesting differential benefits depending on the direction of the medication switch.
