Outpatient insulin use in type 2 diabetes mellitus and acute respiratory distress syndrome outcomes: A retrospective cohort study.

The impact of type 2 diabetes mellitus (T2DM) on acute respiratory distress syndrome (ARDS) is debatable. T2DM was suspected to reduce the risk and complications of ARDS. However, during coronavirus disease 2019 (COVID-19), T2DM predisposed patients to ARDS, especially those who were on insulin at home. To evaluate the impact of outpatient insulin use in T2DM patients on non-COVID-19 ARDS outcomes. We conducted a retrospective cohort analysis using the Nationwide Inpatient Sample database. Adult patients diagnosed with ARDS were stratified into insulin-dependent diabetes mellitus (DM) (IDDM) and non-insulin-dependent DM (NIDDM) groups. After applying exclusion criteria and matching over 20 variables, we compared cohorts for mortality, duration of mechanical ventilation, incidence of acute kidney injury (AKI), length of stay (LOS), hospitalization costs, and other clinical outcomes. Following 1:1 propensity score matching, the analysis included 274 patients in each group. Notably, no statistically significant differences emerged between the IDDM and NIDDM groups in terms of mortality rates (32.8% vs 31.0%, P = 0.520), median hospital LOS (10 d, P = 0.537), requirement for mechanical ventilation, incidence rates of sepsis, pneumonia or AKI, median total hospitalization costs, or patient disposition upon discharge. Compared to alternative anti-diabetic medications, outpatient insulin treatment does not appear to exert an independent influence on in-hospital morbidity or mortality in diabetic patients with non-COVID-19 ARDS.

Chitosan-modified dihydromyricetin liposomes promote the repair of liver injury in mice suffering from diabetes mellitus

Liver injury caused by type-II diabetes mellitus (DM) is a significant public-health concern worldwide. We used chitosan (CS) to modify dihydromyricetin (DHM)-loaded liposomes (DL) through charge interaction. The effect of CS-modified DL (CDL) on liver injury in mice suffering from DM was investigated in vivo and in vitro. CDL exhibited superior antioxidant capacity and stability. Pharmacokinetic analyses revealed a 3.23- and 1.92-fold increase in the drug concentration–time curve (953.60 ± 122.55 ng/mL/h) in the CDL-treated group as opposed to the DHM-treated group (295.15 ± 25.53 ng/mL/h) and DL-treated group (495.31 ± 65.21 ng/mL/h). The maximum drug concentration in blood (Tmax) of the CDL group saw a 2.26- and 1.21-fold increase compared with that in DHM and DL groups. We observed a 1.49- and 1.31-fold increase in the maximum drug concentration in blood (Cmax) in the CDL group compared with that in DHM and DL groups. Western blotting suggested that CDL could alleviate liver injury in mice suffering from DM by modulating inflammatory factors and the transforming growth factor-β1/Smad2/Smad3 signaling pathway. In conclusion, modification of liposomes using CS is a viable approach to address the limitations of conventional liposomes and insoluble drugs.

Insulin dependence negatively impacts outcomes in anterior cervical discectomy with fusions: a 10-year retrospective analysis

BACKGROUND CONTEXTAlthough anterior cervical discectomy and fusion (ACDF) procedures for cervical spine disease have been increasing amid a growing diabetic patient population, there is a paucity of literature focusing on insulin-dependence as a risk-factor for postoperative ACDF complications. PURPOSETo evaluate the differential impact of insulin dependence on perioperative outcomes including total length of stay, surgical, and medical complications within thirty days following ACDF. STUDY DESIGN/SETTINGA retrospective cohort, large multicenter database study. PATIENT SAMPLEThe American College of Surgeons National Surgical Quality Improvement Program database was queried to retrospectively identify patients who had undergone ACDF between 2011 and 2021 using the Current Procedural Terminology code 22551. OUTCOME MEASURESPerioperative surgical and medical complications. METHODSThe study population was divided into 3 groups 1) insulin-dependent diabetes mellitus (IDDM), 2) noninsulin-dependent diabetes mellitus (NIDDM), and 3) no diabetes mellitus (non-DM). One-way analysis of variance for continuous variables and chi-square tests for categorical variables were used to identify differences in perioperative variables between the 3 groups. Multivariable logistic regression analysis assessed the effect of diabetes mellitus status on postoperative medical and surgical outcomes. RESULTSA total of 85,758 ACDF procedures were identified between 2011 and 2021, of which 5,178 were IDDM, 9,652 were NIDDM, and 70,982 were non-DM. The rates of surgical and medical complication varied between the 3 groups. IDDM patients had the highest rates of at least one medical complication (6.1%). Only IDDM increased the risk for medical complications (OR: 1.320, 95% CI [1.144–1.518]) and extended hospital length of stay (LOS) (OR: 1.244, 95% CI [1.071–1.441]) following a multivariate logistic regression analysis. CONCLUSIONPatients with IDDM were at an increased risk for postoperative medical complications and extended hospital LOS. Personalized postoperative management, guided by risk assessment is indicated for this population. These findings can be used to improve risk stratification and informed consent for DM patients who are insulin dependent.

Development, characterization, and evaluation of polymer-based hydrogel membrane patches for intestinal delivery of gliclazide

ABSTRACT The study aimed to develop, characterize, and evaluate matrix-type oral bi-layered mucoadhesive hydrogel membrane patches for the intestinal delivery of gliclazide. Surface pH, drug content, thickness, folding endurance, moisture content, water vapor transmission rate, and swellability of hydrogel membrane patches were found satisfactory. These patches were characterized by SEM, DSC, and FT-IR spectroscopy. In-vitro gliclazide release from these hydrogel membrane patches was sustained over 8 h. Ex-vivo study demonstrated good mucoadhesion of these hydrogel membrane patches. Therefore, these matrix-type oral bi-layered mucoadhesive-natured PNIPAM-co-MM/chitosan made-hydrogel membrane patches for intestinal delivery of gliclazide can be effectively used in type-II diabetes mellitus management.

In Vitro Analysis of Camellia sinensis Leaf Extract Against Diabetes Mellitus.

Diabetes mellitus (DM) poses a significant global health challenge, with its prevalence steadily increasing. Natural compounds derived from plants have garnered attention for their potential therapeutic effects in managing this metabolic disorder. Camellia sinensis, commonly known as tea, is rich in bioactive compounds exhibiting various pharmacological properties. This study investigates the potential anti-diabetic activity of C. sinensis leaf extract through in vitro analysis. Camella sinensisleaf extract was prepared by grinding the plant's leaf into a powder, mixing it with distilled water, and heating. The antidiabetic activity was assessed through α-Amylase and α-Glucosidase inhibitory assays, employing varying concentrations of the plant extract. Molecular docking analysis utilized Autodock 1.5.6 software (The Scripps Research Institute, California, US)to predict ligand-receptor interactions, guiding subsequent experimental validation. Camella sinensisleaf extract exhibited high phenolic content, suggesting potential in managing hyperglycemia. Tannins may aid glucose absorption and inhibit adipogenesis, making them promising for non-insulin-dependent DM (NIDDM). Terpenoids, with antioxidant activity, inhibit advanced glycation. Saponins and steroids were absent. Molecular docking revealed residues like IR, IRS1, and AS160 with significant impact on α-Amylase and α-Glucosidase, comparable to metformin. The findings of this study highlight the promising potential of C. sinensis leaf extract in managing hyperglycemia associated with DM. The high phenolic content aids in glucose regulation. Specifically, the presence of tannins suggests a potential role in modulating glucose absorption and inhibiting adipogenesis, which could be particularly beneficial for individuals with NIDDM.These findings provide valuable insights into the molecular mechanisms underlying the potential therapeutic efficacy of C. sinensis leaf extract against DM, paving the way for further research and development of novel therapeutic interventions in diabetes management.

Uncontrolled diabetes mellitus and the progression of monoclonal gammopathy of undetermined significance to multiple myeloma in US veterans.

7551 Background: Studies have shown that, independent of obesity, the metabolic effects of diabetes mellitus (DM) promote the progression of monoclonal gammopathy of undetermined significance (MGUS) to multiple myeloma (MM). However, it is unclear whether glycemic control is associated with MGUS progression in DM patients. We aimed to evaluate the association between poor glycemic control, measured by HbA1c >6.5%, and progression. Methods: Patients diagnosed with MGUS from 1999-2021 in the Veterans Health Administration (VHA) were identified using a published natural language processing (NLP)-based algorithm. We focused on patients whose MGUS subtype was IgG, IgA, or light chain. We excluded patients lacking body weight measurements from the time of MGUS diagnosis to the end of follow-up to ensure receiving care in the VHA. We further excluded patients with extended gaps >1 year between HbA1c measurements. Time-varying HbA1c measurements during the follow-up, evaluated at 1-day intervals and categorized into uncontrolled (HbA1c >6.5%) or controlled (≤6.5%) DM was the exposure variable. Progression of MGUS to MM was also confirmed by a published NLP algorithm. The association between the time-varying controlled/uncontrolled DM and progression was estimated by multivariable-adjusted hazard ratio (aHR) with death as a competing event. The covariates included sex, race, MGUS subtype as well as age, body mass index, monoclonal protein level, Charlson Comorbidity Index, DM medication, and DM type (type 1, type 2 with insulin-dependency status, type 2 without insulin-dependency status), all at MGUS diagnosis. Same analysis was conducted in a subgroup of patients with non-insulin dependent DM type 2 (NIDDMT2) without insulin use between MGUS diagnosis and the end of follow-up. Results: After applying inclusion and exclusion criteria, we identified 9,682 patients with both DM and MGUS. The multivariable analysis revealed a positive association between poor glycemic control and MM progression (see Table): (aHR 1.27, 95% CI 1.13-1.42). In NIDDMT2 without insulin use (n=3,498), poor glycemic control was associated with MM progression (aHR 1.81; 95% CI 1.57-2.10). Conclusions: For patients with DM and MGUS, the risk of MGUS progression to MM was 27% higher in uncontrolled DM and 81% higher in patients with NIDDMT2. This finding highlights a modifiable risk factor for MM progression in MGUS patients. Future studies should examine if interventions to enhance glycemic control could potentially reduce MGUS progression.

Impact of Diabetes in Patients With Acute Myocardial Infarction Undergoing Coronary Artery Bypass Surgery Within 48 Hours

Diabetic patients with coronary artery disease may benefit from elective coronary artery bypass graft (CABG) surgery. It is unknown whether this merit is transferable to patients with acute myocardial infarction (AMI) undergoing surgery. A total of 1,427 patients underwent CABG within 48 hours of being diagnosed with AMI at the current institution between 2001 and 2019. Of these patients, 206 (14.4%) had insulin-dependent diabetes mellitus (IDDM) and 148 (10.4%) had non-insulin dependent diabetes mellitus (NIDDM). Retrospective data analysis was performed. Patients with NIDDM showed the highest perioperative risk profile, with a EuroScore II of 11.6 (±10.3) compared with 7.8 (±8.0) in non-diabetic patients and 8.4 (±7.8) in patients with IDDM (p<0.001). Sub-analysis demonstrated a higher proportion of non-ST-elevation myocardial infarction patients in the NIDDM cohort compared with the IDDM cohort (70.9% vs 56.8%; p=0.005). Postoperatively, NIDDM patients had more sepsis (p<0.01) and longer ventilation times (p<0.001) compared with non-DM and IDDM patients (p<0.01). Wound healing complications were rare, but almost twice as high in NIDDM patients compared with non-DM and IDDM patients (4.7% vs 0.9% vs 2.4%, respectively). The 30-day mortality was highest in the NIDDM cohort (18.3% vs 11.3% vs 7.8%; p=0.012). Analysis of survival for up to 15 years revealed a significantly reduced survival of diabetic patients compared with non-diabetic patients, with lowest survival rates in NIDDM patients (p<0.001). Non-insulin dependent diabetes mellitus patients undergoing CABG within 48 hours of being diagnosed with AMI are at increased risk of short-term and long-term complications. Therefore, this particular group should undergo a careful evaluation concerning the expected risks and benefits of CABG in this setting.

Developing Research for Five Subtypes of Diabetes with Specific Characteristics

Recently, sub-classifications for adult-onset diabetes have been presented based on cluster analysis. There are 5 exclusive subtypes, with clusters ranging from 1 to 5: severe autoimmune diabetes (SAID), severe insulin-deficient diabetes (SIDD), severe insulin-resistant diabetes (SIRD), mild obesity-related diabetes (MOD), and mild age-related diabetes (MARD), respectively. The related variables known include GAD antibody, age at diagnosis, BMI, HbA1c, and HOMA2-B and HOMA2-IR. From the Outcome Reduction with an Initial Glargine Intervention (ORIGIN) trial, the numerical numbers of the 5 subtypes are 241-1594-914-1595-2673, respectively. The prevalence percentages for the 5 subtypes in 3 countries are as follows: Japan: 5.4-19.0-7.2-28.9-39.5, Germany: 22.0-3.0-11.0-29.0-35.0, and Finland: 9.9-8.9-11.2-22.8-47.3, respectively.

Clinical and functional characterization of a novel KCNJ11 (c.101G > A, p.R34H) mutation associated with maturity-onset diabetes mellitus of the young type 13.

This study aimed to describe the clinical features, diagnostic and therapeutic course of a patient with MODY13 caused by KCNJ11 (c.101G > A, p.R34H) and how it contributes to the pathogenesis of MODY13, and to explore new therapeutic targets. Whole-exome sequencing was used to screen prediagnosed individuals and family members with clinically suspected KCNJ11 mutations. Real-time fluorescence quantitative PCR, western blotting, thallium flux of potassium channels, glucose-stimulated insulin secretion (GSIS), and immunofluorescence assays were used to analyze the regulation of insulin secretion by the KCNJ11 mutant in MIN6 cells. Daily blood glucose levels were continuously monitored for 14 days in the proband using the ambulatory blood glucose meter (SIBIONICS). Mutation screening of the entire exon of the gene identified a heterozygous KCNJ11 (c.101G > A, p.R34H) mutation in the proband and his mother. Cell-based GSIS assays after transfection of MIN6 using wild-type and mutant plasmids revealed that this mutation impaired insulin secretory function. Furthermore, we found that this impaired secretory function is associated with reduced functional activity of the mutant KCNJ11 protein and reduced expression of the insulin secretion-associated exocytosis proteins STXBP1 and SNAP25. For the first time, we revealed the pathogenic mechanism of KCNJ11 (c.101G > A, p.R34H) associated with MODY13. This mutant can cause alterations in KATP channel activity, reduce sensitivity to glucose stimulation, and impair pancreatic β-cell secretory function by downregulating insulin secretion-associated exocytosis proteins. Therefore, oral sulfonylurea drugs can lower blood glucose levels through pro-insulinotropic effects and are more favorable for patients with this mutation.

Clinical Biomarkers of Dyslipidemia in Diabetes Mellitus Type II Patients

Background. This study aims to comparatively investigate the clinical biomarkers of diabetic dyslipidemia in type II diabetes mellitus (TIIDM) patients and healthy controls with no clinical diabetic history. Method. A cross-sectional study was conducted on 100 TIIDM patients age-matched with 100 control subjects. They were evaluated from January 2021 to July 2022 in Narowal, Pakistan. Various biomarkers including total cholesterol (TL), low-density lipoprotein (LDL), high-density lipoprotein (HDL), and triglycerides were measured for each subject. Results. The results showed significantly higher levels of TC (238 ± 30 mg/dl), triglycerides (201 ± 72 mg/dl), and LDL (141 ± 47 mg/dl) in TIIDM patients as compared to control groups’ levels of TC (167 ± 23 mg/dl), triglycerides (175 ± 75 mg/dl), and LDL (95 ± 30 mg/dl). However, HDL level was significantly lower (46 ± 21 mg/dl) in TIIDM patients as compared to control group (54 ± 27 mg/dl). Conclusion. The clinical biomarkers of dyslipidemia are effective risk predictors for cardiovascular diseases in low-income countries such as Pakistan.

Modified 5-Item Frailty Index: A Useful Tool for Assessing the Impact of Frailty on Postoperative Morbidity and Mortality Following Surgical Fixation of Thoracolumbar Fractures

The modified 5-item frailty index (mFI-5) is a comorbidity-based risk stratification tool to predict adverse events following various neurologic surgeries. This study aims to quantify the association between increased mFI-5 and postoperative complications and mortality following surgical fixation of traumatic thoracolumbar fractures. The 2011-2021 American College of Surgeons - National Surgical Quality Improvement Program (ACS-NSQIP) dataset was used to identify patients undergoing fusion surgeries for thoracolumbar spine fractures. The mFI-5 score was calculated based on the presence of 5 major comorbidities: congestive heart failure within 30days before surgery, insulin-dependent or noninsulin-dependent diabetes mellitus, chronic obstructive pulmonary disease, partially dependent or totally dependent functional health status at the time of surgery, and hypertension requiring medication. Multivariate analysis assessed the independent impact of increasing mFI-5 scores on postoperative 30-day morbidity and mortality while controlling for baseline clinical characteristics. A total of 66,904 patients were included in our analysis (54.2% female, mean age 62.27±12.93years). On univariate analysis, higher mFI-5 score was significantly associated with increased risks of superficial surgical site infection, deep surgical site infection, wound dehiscence, unplanned reoperation, pneumonia, unplanned intubation, postoperative ventilator use, progressive renal insufficiency, acute renal failure, urinary tract infection, stroke, myocardial infarction, cardiac arrest, pulmonary embolism, deep vein thrombosis, bleeding requiring transfusion, sepsis, septic shock, and longer hospital length of stay (LOS). On multivariate logistic regression, increasing mFI-5 score versus a mFI-5 score of zero was associated with higher odds of overall complications (mFI-5 ≥2: odds ratio [OR] 1.38 CI: 1.24-1.54, P < 0.001; mFI-5=1: OR 1.18 CI: 1.11-1.24, P < 0.001) and 30-day mortality (mFI-5 ≥2: OR 2.33 CI: 1.60-3.38, P < 0.001). This study demonstrates that frailty, when measured using the mFI-5, independently predicts postoperative complications, hospital LOS, and 30-day mortality after surgical repair of thoracolumbar fractures. These findings are important for risk stratification in patients undergoing thoracolumbar fusion surgery and for standardization in reporting outcomes after those procedures.

Impact of diabetes on short-term outcomes in patients undergoing coronary artery bypass grafting surgery in acute coronary syndrome.

Diabetes mellitus (DM) is associated with concomitant comorbidities, such as atherosclerosis and cardiovascular disease. Coronary artery bypass grafting (CABG) surgery is the optimal therapy in diabetic patients with triple vessel disease. DM is also known to be a relevant risk factor for higher morbidity and mortality in patients who underwent elective CABG procedures. Data regarding outcomes in diabetic patients in acute coronary syndrome (ACS) is heterogeneous. This study aimed to investigate the impact of DM on short-term outcomes in patients who underwent CABG surgery in ACS. A retrospective propensity score matched (PSM) analysis of 1370 patients who underwent bypass surgery for ACS between June 2011 and October 2019 was conducted. All patients were divided into two groups: non-diabetic group (n = 905) and diabetic group (n = 465). In-hospital mortality was the primary outcome. Secondary outcomes were perioperative myocardial infarction, new onset dialysis, reopening for bleeding and duration of intensive care unit (ICU) stay. A subgroup analysis of patients with insulin-dependent and non-insulin dependent DM was also performed. After performing PSM analysis, baseline characteristics and the preoperative risk profile were comparable between both groups. The proportion of patients who underwent total arterial revascularization (p = .048) with the use of both internal thoracic arteries (p < .001) was significantly higher in the non-diabetic group. The incidence of perioperative myocardial infarction (p = .048) and new onset dialysis (p = .008) was significantly higher in the diabetic group. In-hospital mortality was statistically (p = .907) comparable between the two groups. DM was associated with a higher incidence of adverse outcomes, however with comparable in-hospital mortality in patients who underwent CABG procedure for ACS.

Listeria brain abscess: a therapeutically challenging rare presentation of listeriosis

We report a very rare case of Listeria multiple brain abscesses manifested as delirium, which represented diagnostic and therapeutic challenges overcome only by the close cooperation between Infectious Diseases and Neuroradiology, without which a satisfactory outcome would not be achieved.An elderly man presented with confusion and drowsiness with a background of type-II diabetes mellitus. Although computed tomography of the brain only showed frontal lobe oedema, contrast magnetic resonance (MR) imaging showed numerous irregular rim-enhancing lesions containing central diffusion restriction, suggesting multiple pyogenic cerebral abscesses of unclear aetiology. Thereafter, Listeria monocytogenes was isolated from blood cultures, suggesting this as the causative organism. Deemed unsuitable for neurosurgical drainage, the patient received medical management with a protracted course of antibiotics. This case was extremely challenging, due to 1) the impossibility of source control, 2) the small number of effective antibiotics available to treat this condition, and 3) the inevitable antibiotic side-effects, derived from long-term exposure. A successful outcome was only possible thanks to strict close multidisciplinary follow up, requiring frequent MR imaging and a judicious antibiotic choice, including monitoring of their side-effects. Due to the rarity of this condition, there is lack of guidance on its management, hence the importance of multidisciplinary involvement with very close imaging and antibiotic monitoring.

Biomarkers of Neurodegeneration and Alzheimer's Disease Neuropathology in Adolescents and Young Adults with Youth-Onset Type 1 or Type 2 Diabetes: A Proof-of-Concept Study.

Adult-onset diabetes increases one's risk of neurodegenerative disease including Alzheimer's disease (AD); however, the risk associated with youth-onset diabetes (Y-DM) remains underexplored. We quantified plasma biomarkers of neurodegeneration and AD in participants with Y-DM from the SEARCH cohort at adolescence and young adulthood (Type 1, n = 25; Type 2, n = 25; 59% female; adolescence, age = 15 y/o [2.6]; adulthood, age = 27.4 y/o [2.2]), comparing them with controls (adolescence, n = 25, age = 14.8 y/o [2.7]; adulthood, n = 21, age = 24.9 y/o [2.8]). Plasma biomarkers, including glial fibrillary acidic protein (GFAP), neurofilament light chain protein (NfL), phosphorylated tau-181 (pTau181), and amyloid beta (Aβ40, Aβ42), were measured via Simoa. A subset of participants (n = 7; age = 27.5 y/o [5.7]) and six controls (age = 25.1 y/o [4.5]) underwent PET scans to quantify brain amyloid and tau densities in AD sensitive brain regions. Y-DM adolescents exhibited lower plasma levels of Aβ40, Aβ42, and GFAP, and higher pTau181 compared to controls (p < 0.05), a pattern persisting into adulthood (p < 0.001). All biomarkers showed significant increases from adolescence to adulthood in Y-DM (p < 0.01), though no significant differences in brain amyloid or tau were noted between Y-DM and controls in adulthood. Preliminary evidence suggests that preclinical AD neuropathology is present in young people with Y-DM, indicating a potential increased risk of neurodegenerative diseases.

Behind the Hospital Ward: In-Hospital Mortality of Type 2 Diabetes Mellitus Patients in Indonesia (Analysis of National Health Insurance Claim Sample Data).

The rising global prevalence of diabetes mellitus, a chronic metabolic disorder, poses significant challenges to healthcare systems worldwide. This study examined in-hospital mortality among patients diagnosed with non-insulin-dependent diabetes mellitus (NIDDM) of ICD-10, or Type 2 Diabetes Mellitus (T2DM), in Indonesia, utilizing hospital claims data spanning from 2017 to 2022 obtained from the Indonesia Health Social Security Agency or Badan Penyelenggara Jaminan Sosial (BPJS) Kesehatan. The analysis, which included 610,809 hospitalized T2DM patients, revealed an in-hospital mortality rate of 6.6%. Factors contributing to an elevated risk of mortality included advanced age, the presence of comorbidities, and severe complications. Additionally, patients receiving health subsidies and those treated in government hospitals were found to have higher mortality risks. Geographic disparities were observed, highlighting variations in healthcare outcomes across different regions. Notably, the complication of ketoacidosis emerged as the most significant risk factor for in-hospital mortality, with an odds ratio (OR) of 10.86, underscoring the critical need for prompt intervention and thorough management of complications to improve patient outcomes.

Exogenous Thyroxine Normalizes Decreased Heart Rate in Insulin Resistant OLETF Rats

Diabetic cardiomyopathy (DCM) is defined as heart failure in the absence of overt clinical coronary artery disease, valvular disease, hypertension, and dyslipidemia in diabetic patients. Patients with T2DM display left ventricular dysfunction, fibrosis, and abnormal cell signaling leading to diastolic and systolic dysfunction. Increased left ventricular mass and fibrosis potentially leads to abnormal diastolic function. Substantial data exists demonstrating both insulin-dependent and non-insulin dependent diabetes impairs left ventricular function. During insulin resistance, a metabolic shift occurs favoring fatty acid metabolism at the expense of impaired glucose metabolism, leading to lipotoxicity, increased oxidative stress, and inflammation. Thyroid hormones have shown to be cardioprotective. We have previously shown exogenous thyroxine treatment increased GLUT4 translocation and nuclear factor erythroid 2-related factor 2 (Nrf2) in cardiac tissue, demonstrating the potential to improve glucose metabolism and increase antioxidant defense mechanisms. Insulin resistant, Otsuka Long Evans Tokushima Fatty (OLETF) rats were used to assess the effects of exogenous thyroxine (T4) on left ventricular cardiac function and hemodynamics to assess if the previously observed improvements in cellular metabolism translated to functional improvements. Rats were assigned to three groups: (1) lean, Long Evans Tokushima Otsuka (LETO; n=7), (2) untreated OLETF (n=6), and (3) OLETF + T4 (8 μg/100g BM/d × 6 wks, n=7). Left ventricular function was measured by the pressure-volume system. Heart mass increased in untreated OLETF (1.46 ± 0.08) and treated OLETF (1.61 ± 0.16) compared to LETO (1.19 ± 0.08). Cardiac output (CO) and stroke volume were 26% and 56% greater in untreated OLETF compared to LETO. Heart rate (HR) was 27% lesser in untreated OLETF compared to LETO. While exogenous T4 did not alter CO and SV compared to untreated OLETF, it did normalize HR to LETO levels. The differences in CO between LETO and OLETF suggest that elevated T4 alters the mechanisms (SV vs HR) by which CO is elevated during MetS. The changes may be compensatory to accommodate the cardiac hypertrophy observed in the strain. American Heart Association Award # 946746 APS Porter Physiology Development Fellow (2nd year).

Pola penggunaan obat anti diabetes mellitus tipe-II pada pasien rawat inap di RSUD Praya tahun 2021

Diabetes mellitus is a metabolic disease characterized by hyperglycemia due to abnormalities in insulin secretion. The prevalence of people with diabetes mellitus in Indonesia reached 6.2% per year in 2020 and ranks 7th in the world with 8.5 million people. Based on the results of observations at the Praya Hospital in 2021, type-II diabetes mellitus is the 4th highest-order disease suffered by the community, especially Central Lombok Regency, with a total incidence of 131 patients. This study aims to determine the pattern of drug use and HbA1c profile in patients with type-II diabetes mellitus in the inpatient installation of Praya Hospital in 2021. This study was retrospective, using the Nonprobability Sampling method, namely the type of purposive sampling so that a sample of 96 medical records of diabetes mellitus patients was obtained type-II. The data is presented as pie charts and tables in percentages, which were analyzed using Microsoft Excel and SPSS version 25. From the results of this research, it was found that the pattern of drug use at Praya Hospital in 2021 was given the highest from each group namely the oral antidiabetic drug group (OAD) was in the Biguanid class with 61 drugs (8,13%), while insulin drugs were in the Rapid-Acting class with 343 drugs (45,73%), and the OAD + Insulin combination with 119 drugs (15,87%). For the HbA1c profile, high HbA1c levels were found in 76 patients (79%). This shows that blood glucose control is not reasonable. Based on the study's results, the recommended recommendation is that patients routinely control blood sugar and be educated on the accuracy of drug use to control blood sugar.

Effect of Integrated Nutrient Management on Growth and Yield of Gymnema sylvestre (R.Br.), in Jharkhand (India)

Gymnema sylvestre (R.Br.) is a climber plant commonly called Gudmar belongs to family Apocynaceae is deciduous seed plant. A field experiment was conducted during 2017-2019 at the experimental field of Birsa Agricultural University, Ranchi, Jharkhand (India) to find out the integrated nutrient management technique for increasing the yield of the leaf of Gymnema sylvestre (R.Br.). The experiment was laid out in a Randomized Block Design with 12 treatments and one control replicated thrice. Nine plants were transplanted in each treatment at 80 cm x 80 cm spacing level. It is an important medicinal plant used as an herbal remedy for high blood sugar (type-II diabetes). The optimum doses of organic and inorganic fertilizer combination should be 10t ha-1 VC+10t ha-1 NC+5t ha-1 KC +30:40:40 kg NPK ha-1 for the maximum productivity of leaves and stem of Gudmar. The combination of organic and inorganic is superior to the application of fertilizer alone and controls for achieving higher growth and yield.

Mangosteen Peel Extract vs Tetracycline Gel in Treatment of Periodontal Abscess in Type-2 Diabetes – A Randomized Clinical Trial

Herbal products are gaining popularity due to their diverse biological action and safety. Mangosteen peel extract has antibacterial and anti-inflammatory properties and can be used to treat periodontal diseases. Objective: To compare the efficacy of mangosteen peel extract and tetracycline gel as an adjunct to non-surgical management of periodontal abscess in type-II diabetes patients. Methods: This was a double blinded, randomized clinical trial included 20 Patients with Type-II diabetes. Both test and control groups received NSPT followed by adjunctive local application of mangosteen peel extract and tetracycline gel. Clinical parameters i.e., Probing depth (PPD), Clinical attachment level (CAL), Bleeding Index (BI) and Landry’s healing index (HI) were evaluated at base line and 1 month. Results: In intra and intergroup analysis, both the test and control groups had a better reduction in PPD, BI and CAL with a statistical significance. However, there was no statistical significance between the groups in healing index and showed no change in patient perception in both the groups. Conclusion: 4% mangosteen gel has significantly reduced the BI and PPD with increased CAL and acceptable subjective perception with no recurrence of periodontal abscess over the traditionally used tetracycline gel.

CORDAX web server: an online platform for the prediction and 3D visualization of aggregation motifs in protein sequences.

Proteins, the molecular workhorses of biological systems, execute a multitude of critical functions dictated by their precise three-dimensional structures. In a complex and dynamic cellular environment, proteins can undergo misfolding, leading to the formation of aggregates that take up various forms, including amorphous and ordered aggregation in the shape of amyloid fibrils. This phenomenon is closely linked to a spectrum of widespread debilitating pathologies, such as Alzheimer's disease, Parkinson's disease, type-II diabetes, and several other proteinopathies, but also hampers the engineering of soluble agents, as in the case of antibody development. As such, the accurate prediction of aggregation propensity within protein sequences has become pivotal due to profound implications in understanding disease mechanisms, as well as in improving biotechnological and therapeutic applications. We previously developed Cordax, a structure-based predictor that utilizes logistic regression to detect aggregation motifs in protein sequences based on their structural complementarity to the amyloid cross-beta architecture. Here, we present a dedicated web server interface for Cordax. This online platform combines several features including detailed scoring of sequence aggregation propensity, as well as 3D visualization with several customization options for topology models of the structural cores formed by predicted aggregation motifs. In addition, information is provided on experimentally determined aggregation-prone regions that exhibit sequence similarity to predicted motifs, scores, and links to other predictor outputs, as well as simultaneous predictions of relevant sequence propensities, such as solubility, hydrophobicity, and secondary structure propensity. The Cordax webserver is freely accessible at https://cordax.switchlab.org/.
