Vitamin D status in Type 2 Diabetes Mellitus in a Tertiary Level Hospital

Background: There is increasing evidence of a relationship between vitamin D status and type 2 diabetes. Diabetes has also been found to be associated with 25(OH)D (vitamin D) deficiency and the role of vitamin D has recently emerged, especially in preventing cardiovascular diseases and cancer. and insulin resistance. Objective: This study aimed to compare vitamin D deficiency between healthy and Type 2 Diabetes Mellitus (T2DM) patients. Methods: This cross-sectional study was conducted from July 2021 to June 2022 in the Department of Physiology, Rangpur Medical College, Rangpur. For this study, a total number of 100 subjects were selected among them 50 non-diabetic healthy subjects were included as control and 50 Type 2 Diabetes Mellitus patients were included as cases. The subjects of control were selected from the surrounding community of Rangpur district and subjects of cases were selected from Diabetic Association and from Outdoor of Endocrinology Department, Rangpur Medical College and Hospital, Rangpur. For statistical analysis, an independent sample t-test was performed by computer-based software SPSS-23.0 version for windows. Results: The mean vitamin D level was lower in the diabetic patients than in non-diabetic participants (14.1±8.3 ng/ml and 37.3±11.3, p<0.001). Conclusions: Early screening for serum vitamin D level is recommended for T2DM patients. Hence, it is crucial to promptly address any deficiencies in vitamin D levels. J Rang Med Col.

Thiazolidinediones Decrease the Recurrence of Intracerebral Hemorrhage in Type 2 Diabetes Mellitus Patients: A Nested Case-Control Study.

Preclinical evidence demonstrated the therapeutic potential of TZDs for the treatment of intracerebral hemorrhage (ICH). The present study conducted an investigation of cerebrovascular and cardiovascular outcomes following ICH in patients with type 2 diabetes mellitus (T2DM) treated with or without TZDs. This retrospective nested case-control study used data from the Taiwan National Health Insurance Research Database. A total of 62,515 T2DM patients who were hospitalized with a diagnosis of ICH were enrolled, including 7,603 TZD users. Data for TZD non-users were extracted using propensity score matching. Primary outcomes included death and major adverse cardiovascular events (MACEs), which were defined as a composite of ischemic stroke, hemorrhagic stroke (HS), acute myocardial infarction (AMI), and congestive heart failure (CHF). Patients aged < 20 years with a history of traumatic brain injury or any prior history of MACEs were excluded. TZD users had significantly lower MACE risks compared with TZD non-users following ICH (adjusted hazard ratio [aHR]: 0.90, 95% confidence interval [CI]: 0.85-0.94, p < 0.001). The most significant MACE difference reported for TZD users was HS, which possessed lower incidence than in TZD non-users, especially for the events that happened within 3 months following ICH (aHR: 0.74, 95% CI: 0.62-0.89 within one month, p < 0.01; aHR: 0.68, 95% CI: 0.54-0.85 between 1-3 month). The use of TZD in patients with T2DM was associated with a lower risk of subsequent HS and mortality following ICH.

Determinants of cardiovascular disease among type 2 diabetic patients attending diabetic follow-up clinic in Arba Minch general hospital, southern Ethiopia: an unmatched case-control study.

Cardiovascular disease (CVD) is a major cause of death and disability among patients with type 2 diabetes, especially in low-income and middle-income countries. Type 2 diabetes mellitus (T2DM) patients have a 2-4-fold increased risk of CVD. There is limited data about cardiovascular disease risks and its determinants among T2DM patients in Ethiopia. This study aimed to identify possible predictors of cardiovascular diseases among adults with T2DM in southern Ethiopia. A hospital-based unmatched case-control study was conducted at southern Ethiopia Arbaminch Hospital on 196 randomly selected patients with type 2 diabetes on follow-up (98 cases and 98 controls). The authors collected data using a structured interviewer-administered questionnaire, laboratory checklist, and additional document review of T2DM patients. A multivariable binary logistic regression was fitted to identify cardiovascular disease determinants, and the findings were presented using an adjusted odds ratio (AOR) with a 95% CI. The mean reported age (±SD) of the cases and the controls was 56.3.3 (±8.9) and 52.3 (±9.3) years, respectively. The two identified independent determinants of cardiovascular disease with AOR [95% CI] were hypertension [AOR=4.953, 95% CI (2.47, 9.93) and persistent urine albuminuria [AOR=12.9, 95% CI (3.98, 41.7)]. This study showed that having high blood pressure and persistent urine albuminuria are independent predictors of cardiovascular disease in T2DM patients. The current study setting needs an intervention for mitigating these cardiovascular disease determinants.

Real-world Safety and Effectiveness of Insulin Glargine 300 U/mL in Participants with Type 2 Diabetes Mellitus During the Period of Ramadan in Four Countries (Egypt, Jordan, Lebanon, and Turkey): A Prospective Observational Study.

This non-interventional observational study aimed to describe the clinical outcomes of patients with T2DM treated with Gla-300 during the period of Ramadan. Type 2 diabetes mellitus (T2DM) patients who decide to fast during the holy month of Ramadan face several challenges in achieving glycemic control without increasing the risk of hypoglycemia. Insulin glargine-300 (Gla-300) has well-established safety and efficacy in improving glycemic control in multiple randomized clinical trials (RCTs). However, limited evidence is available regarding its safety and effectiveness during fasting. The objective of this study was to assess the safety and clinical outcomes of insulin glargine-300 (Gla-300) in T2DM patients before, during, and after Ramadan. We conducted a prospective, observational, non-comparative, multicenter study on patients with T2DM currently treated with Gla-300 who planned to fast and continue on Gla-300 during Ramadan in four countries (Egypt, Jordan, Lebanon, and Turkey). The study outcomes included the change in glycemic parameters and incidence of hypoglycemia before, during, and after Ramadan. One hundred and forty T2DM patients were included. Nearly 61% of the included patients had a duration of diabetes of <10 years. The mean Gla-300 daily doses during the pre-Ramadan, Ramadan, and post-Ramadan periods were 22.2 ±7.4, 20.4 ±7.5, and 22.5 ±4.7 IU, respectively. The mean change values from pre-Ramadan to Ramadan and post-Ramadan were -1.7 ±6.9 IU and 0.5 ±4.7 IU, respectively, among the included patients. The mean HbA1c decreased during the study period initiating from 7.9% ±1.4% pre-Ramadan to 6.9% ±0.4% post-Ramadan. The overall HBA1c target value was 6.9% ±0.4%, while the HbA1c target was achieved by 29 patients (21.9%). The mean fasting blood glucose (FPG) showed a reduction from baseline value in the post-Ramadan period by -0.9 ±2.3 mmol/L. Five patients (3.57%) had symptomatic documented hypoglycemia during Ramadan, and none was considered to have severe hypoglycemia. Our study showed that insulin Gla-300 maintained the glycemic control of T2DM patients who decided to fast during the holy month of Ramadan without increasing the risk of hypoglycemia. Regular self-monitoring of blood glucose levels during Ramadan is highly recommended to avoid possible complications.

Event-Related Potential Changes Following 12-week Yoga Practice in T2DM Patients: A Randomized Controlled Trial.

Introduction. Type 2 diabetes patients are more likely to experience cognitive decline (1.5%) and dementia (1.6%) than healthy individuals. Although cognitive impairment adversely affects Type 2 diabetes mellitus (T2DM) patients, it is the least addressed complication of T2DM patients. Objective. The present study attempts to examine the changes in cognitive performance of T2DM patients and the probable factors contributing to the changes following 12-week yoga practice. Methods. The current study is a parallel group randomized controlled trial that compared the outcomes of the participants randomized to a yoga group (YG) (n = 25) and to a wait-list control group (n = 29). The study assessed N200 and N450 event-related potential (ERP) components following the Stroop task, heart rate variability (HRV) and HbA1c before and after the intervention. Results. The mean amplitude of the N200 ERP component showed a significant group difference after the intervention, demonstrating an improved neural efficiency in the process of conflict monitoring and response inhibition. No differences were present for the N450 component. T2DM patients showed reduced heart rate and increased mean RR following yoga practice without any corresponding changes in other HRV parameters, demonstrating an overall improvement in cardiac activity. Along with that yoga practice also reduced HbA1c levels in T2DM patients, indicating improved glycemic control. Moreover, HbA1c levels were negatively correlated with reaction time after the intervention, indicating an impact of glycemic control on cognitive performance. Conclusion. The 12-week yoga practice improved cognitive performance by enhancing the processes of conflict monitoring and response inhibition. Further, improved cognitive performance postintervention was facilitated by improved glycemic control.

Complement Proteins in Serum Astrocyte-Derived Exosomes Are Associated with Poststroke Cognitive Impairment in Type 2 Diabetes Mellitus Patients.

The complement system plays crucial roles in cognitive impairment and acute ischemic stroke (AIS). High levels of complement proteins in plasma astrocyte-derived exosomes (ADEs) were proven to be associated with Alzheimer's disease. We aimed to investigate the relationship of complement proteins in serum ADEs with poststroke cognitive impairment in type 2 diabetes mellitus (T2DM) patients. This study analyzed 197 T2DM patients who suffered AIS. The Beijing version of the Montreal Cognitive Assessment (MoCA) was used to assess cognitive function. Complement proteins in serum ADEs were quantified using ELISA kits. Mediation analyses showed that C5b-9 and C3b in serum ADEs partially mediate the impact of obstructive sleep apnea (OSA), depression, small vessel disease (SVD), and infarct volume on cognitive function at the acute phase of AIS in T2DM patients. After adjusting for age, sex, time, and interaction between time and complement proteins in serum ADEs, the mixed linear regression showed that C3b and complement protein Factor B in serum ADEs were associated with MoCA scores at three-, six-, and twelve-months after AIS in T2DM patients. Our study suggested that the impact of OSA, depression, SVD, and infarct volume on cognitive impairment in the acute stage of AIS may partially mediate through the complement proteins in serum ADEs. Additionally, the complement proteins in serum ADEs at the acute phase of AIS associated with MoCA scores at three-, six-, twelve months after AIS in T2DM patients.REGISTRATION: URL: http://www.chictr.org.cn/,ChiCTR1900021544.

Influencing factors of health-related quality-of-life perceived by both children/adolescents patients with type-1 diabetes mellitus and their parents: A North-African study

Aim To determine the influencing factors of health-related quality-of-life (HRQoL) perceived by North-African children/adolescents with type-1 diabetes-mellitus (T1DM) and their parents. Methods It was a cross sectional study conducted in Tunisia. A total of 116 patients ( ie ; 43 children and 73 adolescents) and their parents were included. The Arabic validated version of the Pediatric Generic Core Quality-of-Life Inventory 4.0-Scale (PedsQL4.0) was used to evaluate the HRQoL of children/adolescents as perceived by patients and parents. The dependent data were the patients’ self-report and the parents’ proxy-report of the PedsQL4.0 total scores, and the independent data were the patients and parents characteristics. Results Patients’ PedsQL4.0 total score was influenced significantly by siblings in the family &gt; 2; lipodystrophy, and glycosylated hemoglobin (HbA1C). The combination of these factors explained 34.84% of the PedsQL4.0 total score variability. Parents’ PedsQL4.0 total score was influenced significantly by lipodystrophy, siblings; body mass index (BMI), hypoglycemia episodes, and HbA1C. The combination of these factors explained 56.92% of the PedsQL4.0 total score variability. Conclusion T1DM patients self-reported HRQoL was influenced by siblings in the family &gt; 2; lipodystrophy, and HbA1C. The parents’ proxy-report HRQoL was influenced by lipodystrophy, siblings, BMI, hypoglycemia episodes, and HbA1C.

Evaluation of left ventricular function in normotensive type-2 dm patients by echocardiography

The prevalence of diabetes mellitus (DM) is increasing globally. Indians are also believed to have a greater degree of insulin resistance and a stronger genetic predisposition to diabetes. Type II DM is a risk factor for cardiovascular disease and cardiovascular complications and these are a major cause of mortality and morbidity in diabetic patients. Left ventricular dysfunction, increased left ventricular wall thickness, increased left ventricular mass, and specific diabetic cardiomyopathy are some of the cardiovascular complications associated with diabetes. So the present study was performed to assess normotensive diabetic patients by echocardiography to evaluate their left ventricular function. A case control cross sectional study was conducted on 40 normotensive type 2 diabetes mellitus patients. 40 patients who were non-diabetic, non-hypertensive were taken as a control. A standard 2D echocardiography with M mode and Doppler was performed on case and control. In our study among 40 cases, 55% were male and 45% were female with mean age of case population being 47.5±7.24 year and among 40 controls, 50% were male and 50% were female with mean age 48.03±7.14 year. Mean BMI in case group was 29.49±2.37 kg/m2 and in control group 29.36±2.46 kg/m2. In our study we found that LVDD was present in 57.5% cases, 47.5% of cases had grade 1 LVDD whereas 10% had grade 2 LVDD. In comparison, only 10% of controls had LVDD with all of them having grade 1 LVDD. Also LV Systolic dysfunction, LVM and LVMI were higher in cases as compared to controls. Thus we concluded that the prevalence of left ventricular diastolic dysfunction in asymptomatic, normotensive patients with type 2 DM without significant coronary artery disease is much higher than previously suspected as evidenced by the results of this study and also of similar other studies and it increases with the duration of Diabetes. Left ventricular systolic dysfunction, LVM and LVMH prevalence were also higher in cases as compared to controls and they also correlate with duration of Diabetes.

Evaluation of nail fold capillaroscopy changes in patients with diabetic retinopathy and healthy controls, and its correlation with disease duration, HbA1c levels and severity of diabetic retinopathy: An observational study

Background Diabetic retinopathy (DR) is an important microvascular complication of long-term type 2 diabetes mellitus (T2DM) leading to blindness if not properly diagnosed and managed. It can develop as early as 7 years before the diagnosis of diabetes. Nail fold capillaroscopy (NFC) is a non-invasive technique for observing capillary microvasculature and there are few studies which have explored the use of NFC in diabetes mellitus patients. Objective To study the nail fold capillaroscopic alterations in patients with T2DM having diabetic retinopathy and compare them to healthy controls. The secondary objective was to correlate the NFC findings with the duration of diabetes, haemoglobin A1c (HbA1c) levels and the severity of DR. Materials and methods This cross-sectional observational study enrolled 200 patients - 100 cases with T2DM having diabetic retinopathy (as per the American Diabetes Association criteria and Diabetic Retinopathy Disease Severity Scale) and 100 healthy age and sex-matched controls. All patients were subjected to NFC and ophthalmological assessment. Results NFC revealed that patients with DR showed significantly higher frequencies of tortuous, dilated, bushy, meandering, angulated capillaries, avascular areas and micro-haemorrhages as compared to healthy controls (p &lt; 0.05). In proliferative DR (PDR), the frequency of tortuous, bushy capillaries, and avascular areas was statistically high and the capillary density was reduced as compared to non-proliferative DR. The DR patients with longer disease duration (&gt;20) years had a significantly higher frequency of tortuous capillaries, avascular areas, meandering, angulated and dilated capillaries. The frequency of tortuosity, avascular areas, and bushy areas was significantly higher in patients with poor glycaemic control (HbA1c &gt;11). Limitations A larger sample size study with different demographic populations could have provided a broader picture of NFC changes in T2DM patients with DR. Discussion NFC may act as a surrogate marker of retinal involvement in patients with DM and should be performed at regular intervals. Conclusion NFC is a quick, simple, safe, and non-invasive method to assess the capillaroscopic alterations in diabetic patients which inturn can help in assessing the severity of DR.

Incident Cancer Risk in Patients with Incident Type 2 Diabetes Mellitus in Hungary (Part 1)

(1) Background: Patients with type 2 diabetes mellitus (T2DM) are at higher risk of cancer but how these two diseases associate is still debated. The goal of this study was the assessment of the overall incidence of cancer among patients with newly diagnosed T2DM in Hungary. (2) Methods: A nationwide, retrospective, longitudinal study was performed using a Hungarian database. After exclusion of cases of age &lt; 18 years, with gestational diabetes, with polycystic ovary syndrome, and with type 1 and prevalent type 2 diabetes mellitus, the incident T2DM (approx. 50,000 cases yearly) and for comparison, the diabetes-free Hungarian adult population (approx. 7,000,000 cases yearly) was included in the study. The primary endpoints were the overall and site-specific incidence and annual percentage change of the incidence of cancer in both populations. (3) Results: The overall incidence of cancer in patients amounted to 29.4/1000 and 6.6/1000 with or without T2DM, respectively, and the OR (95%CI) of cancer of the T2DM group was 4.32 (4.14–4.53), p &lt; 0.0001. The risk of having cancer was age dependent. The incidence of cancer was declining in the non-diabetic but was unchanged in the T2DM population. The average lag time of diagnosing cancer after the detection of T2DM was 3.86 months. (4) Conclusions: Incident T2DM is associated with a significantly higher overall risk of incident cancer, with a reverse correlation of age. Newly registered T2DM patients were suggested to be screened for cancer within 6 months.

A comparative study of multiple biomarkers levels in complicated versus noncomplicated type 2 diabetic patients.

The prevalence of diabetes mellitus is growing globally and the management of diabetes is a critical issue for public health. This study aimed to analyze the concentration of different biomarkers in patients with type 2 diabetes mellitus (T2DM) without complication, T2DM patients with complication (T2DM+C), and compared to healthy controls (HC). For this aim, there were 164 participants: 59 T2DM, 60 T2DM+C, and 45 HC. Venous blood was collected and the levels of Hemoglobin A1C (HbA1C), fasting blood glucose, Interleukin-31 (IL-31), IL-35, glutamic acid decarboxylase antibody (GADA), developmental locus-1 (Del-1), fibroblast growth factor-9 (FGF-9) and FGF-18) and lipid profile (total cholesterol, low-density lipoprotein (LDL), high-density lipoprotein (HDL) and triglyceride) were analyzed. Results showed that IL-31 was significantly higher in T2DM compared to HC (p<0.0001), and compared to T2DM+C (p<0.0001). IL-31 was significantly lower in T2DM+C than HC (p=0.009). The level of serum GADA was significantly elevated in T2DM compared to HC (p=0.0009), and T2DM+C (p=0.03). There was a significant correlation between (IL-31, IL-35, GADA, Del-1, FGF-9 and FGF-18). The duration of having diabetes was significantly longer in T2DM+C compared to T2DM (p<0.0001). However, there was no significant difference in the level of HBA1C% between T2DM+C and T2DM patients (p=0.98). In conclusion, there were significant differences in biomarker concentrations between all three groups. This indicates that the monitoring of multiple biomarkers may be of value in the controlling of T2DM in the future.

Knowledge and Attitude Towards Insulin Therapy in Type 2 Diabetes Mellitus Patients and Associated Factors at an Adult Endocrine Clinic of SPHMMC Addis Ababa Ethiopia

&amp;lt;i&amp;gt;Background:&amp;lt;/i&amp;gt; Diabetes Mellitus (DM), a chronic disease characterized by elevated blood glucose levels, is associated with severe complications. Type 2 DM (T2DM), the most prevalent form of DM in adults, is characterized by varying degrees of insulin deficiency or resistance. The prevention or delay of macrovascular and microvascular problems associated with DM depends on achieving appropriate glycemic control. The percentage of T2DM patients failing to reach glycemic targets keeps rising even with the expanded availability of numerous anti-hyperglycemic drugs and evidence-based treatment guidelines. The delay in treatment intensification despite inadequate glucose control—often referred to as clinical or therapeutic inertia-contributes significantly to this trend.&amp;lt;i&amp;gt; Objective:&amp;lt;/i&amp;gt; This study aims to evaluate the understanding and perceptions of insulin therapy among patients with T2DM. The study focuses on patients under follow-up care at the Adult Endocrine Clinic of St. Paul Hospital Millennium Medical College.&amp;lt;i&amp;gt; Method and Material:&amp;lt;/i&amp;gt; An institutional-based, cross-sectional study was carried out from January to March 2021 to evaluate knowledge and attitudes regarding insulin therapy and related factors. A structured questionnaire was used for interviews with a representative sample of 271 T2DM patients who are receiving follow-up care at the endocrine clinic at SPHMMC. The SPSS, version 25, was the software utilized. The statistical significance of the relationship between the dependent and independent variables was assessed using a 95% confidence interval and a p-value less than 0.05.&amp;lt;i&amp;gt; Results:&amp;lt;/i&amp;gt; The majority of the respondents were between the ages of 56 and 65, with a mean age of 57.35 years. More than half of the participants, accounting for 231 (85.2%) of the total, were from urban areas. Out of the 271 respondents, approximately 85.6% demonstrated poor knowledge of insulin therapy, and around 37.6% exhibited negative attitudes towards it. Factors such as age, occupation, and a history of long-term Oral Antidiabetic Drug use were found to be associated with the level of knowledge about insulin. In addition to these factors, marital status and a family history of insulin use were found to be associated with patients’ attitudes towards insulin. &amp;lt;i&amp;gt;Conclusions:&amp;lt;/i&amp;gt; Our study identified a significant knowledge gap about insulin usage among T2DM patients in the designated study area. We recommend the implementation of regular, structured health education programs, delivered by trained health professionals. This approach is expected to enhance both the knowledge and attitudes toward insulin usage among patients attending follow-up sessions at the SPHMMC diabetic clinic.

Ketogenic Diets Hold Therapeutic Potential Against Periodontal Inflammation

Abstract Purpose of Review Periodontitis, one of the most prevalent diseases in the world, is caused by the accumulation of dysbiotic microbial biofilm on the teeth leading to chronic inflammation of the tissues surrounding the teeth. Type 2 diabetes mellitus (T2DM), obesity, chronic stress, and smoking are some of the risk factors for the disease. A high-carbohydrate diet also increases the risk of periodontal inflammation. Modifying diet and nutrition could serve as a preventive and therapeutic tool to target multiple risk factors simultaneously. Recent Findings Emerging evidence shows that the ketogenic diet induces hormetic stress and switches on various cell-protective anti-inflammatory and antioxidant mechanisms. The ketogenic diet also improves mitochondrial function, DNA repair, and autophagy. The diet can effectively treat periodontitis risk factors such as T2DM and obesity. By restricting carbohydrates, the diet improves glycaemic control in T2DM patients and can effectively produce fat loss and reduce BMI (body-mass index) in obese patients. Poor long-term compliance and high cost are the drawbacks of the diet and the potential of the diet to increase cardiovascular disease risk needs further investigation. Summary Taken together, ketogenic diets, through various mechanisms reduce inflammation, mitigate oxidative stress, improve metabolic health, and can be used as a therapeutic tool to treat periodontal inflammation. Since robust scientific evidence for the ketogenic diet is currently scarce, future research should study the diet's efficacy, effectiveness, and safety in managing periodontal inflammation.

Technology for the Management of Type 1 Diabetes Mellitus in Saudi Arabia and MENA Region: A Systematic Review.

Diabetes technology in the form of digital health or medical devices holds a promise for improving the quality of life and glycemic outcomes. A comprehensive insight into diabetes technology and its impact in Saudi Arabia and the MENA region may improve type 1 diabetes mellitus (T1DM) management. This study aimed to assess the impact of different DM-specific technologies: insulin pump therapy, continuous glucose monitoring (CGM), and automated insulin delivery system in terms of glycemic control and QoL among T1DM patients in Saudi Arabia and the MENA region. A systematic literature search was performed in PubMed and Scopus from 2005 until August 2023. The search was based on the PICO strategy, focusing on T1DM patients, diabetes technology, and QoL. The inclusion criteria were studies illustrating the effect of diabetes technologies on glycemic control or quality of life or both among T1DM patients. Systematic reviews, books, letters, or studies, including type 2 diabetes mellitus, were excluded. From 101 articles, eighteen studies were duplicated, and thirty-three studies were excluded after reading the title and abstract. Of the 50 articles analyzed, twenty-five articles did not meet the inclusion criteria. Therefore, 25 articles involving a total of 3088 participants were enrolled in the study. It was shown that a continuous glucose monitoring system and continuous subcutaneous insulin infusion improved the glycemic control and the QoL of T1DM patients. There was a positive impact of insulin pumps, continuous glucose monitoring (CGM) systems, and telemedicine in achieving optimal glucose control and better QoL. Further studies are recommended to clarify the significant role of advanced diabetes technologies.

Association between Lipoprotein(a) and premature atherosclerotic cardiovascular disease: a systematic review and meta-analysis

Abstract Background and aims High Lipoprotein(a) [Lp(a)] level has been demonstrated as an important risk factor for atherosclerotic cardiovascular diseases (ASCVD) amongst the older populations, whereas its effects in the younger population remain unclear. This study evaluated the associations between Lp(a) and the risk of premature ASCVD. Method and results PubMed and Embase were searched for related studies until Nov 12, 2023. 51 studies including 100,540 participants were included. Mean age of patients ranged from 35.3 to 62.3 years. The proportion of male participants ranged from 0% to 100%. The mean follow-up was provided in five studies ranging from one year to 40 years. The definition of elevated Lp(a) varied among studies, such as &amp;gt;30mg/dL,  &amp;gt; 50mg/dL, the top tertiles, the top quartiles, the top quatiles and so on. Higher Lp(a) was significantly associated with the composite ASCVD (OR: 2.15, 95% CI: 1.53-3.02, P &amp;lt; 0.001), especially for CAD (OR: 2.44, 95%CI: 2.06-2.90, P &amp;lt; 0.001) and PAD (OR: 2.56, 95%CI: 1.56-4.21, P &amp;lt; 0.001). This association remained significant in familial hypercholesterolemia (FH) (OR: 3.11, 95%CI: 1.63-5.96, P &amp;lt; 0.001) and type 2 diabetes mellitus (T2DM) patients (OR: 2.23; 95%CI: 1.54-3.23, P &amp;lt; 0.001).Significant results were observed in South Asians (OR: 3.71, 95%CI: 2.31-5.96, P &amp;lt; 0.001), Caucasians (OR: 3.17, 95%CI: 2.22-4.52, P &amp;lt; 0.001), and patients with baseline low density lipoprotein cholesterol (LDL-C) level ≥ 2.6mmol/L. Conclusion Elevated Lp(a) predicts the risk of the composite or individual ASCVD in young, regardless of study design, gender, population characteristics (community or hospitalized), different premature definitions, and various Lp(a) measurement approaches. And this association was important in South Asians, Caucasians, FH patients, T2DM patients and patients with baseline LDL-C level ≥ 2.6mmol/L.

Effects of Metformin Therapy on Thyroid Volume and Functions in Patients with Newly Diagnosed Type 2 Diabetes Mellitus: A Single-center Prospective Study.

Patients with impaired glucose metabolism have increased thyroid volume and a higher prevalence of nodules. Yet, some studies show that there is an improvement in these thyroid parameters after diabetes treatment. Our observational study aimed to reveal the effect of treatment on thyroid function, thyroid volume, and the presence of nodules in newly diagnosed type 2 diabetes mellitus (T2DM) patients who were started on metformin treatment. Euthyroid and subclinically hypothyroid patients with a serum TSH level of <10 mU/L, who were newly diagnosed with T2DM and started on metformin as an antidiabetic treatment and not used any thyroid medication previously, were included in our study. Patients' characteristics were recorded. Baseline and 6th-month serum thyroid function tests were scheduled. Baseline and 6th-month thyroid gland characteristics were examined by thyroid ultrasonography. A total of 101 (37 males, 64 females) newly diagnosed T2DM patients with euthyroid (n=95) or subclinical hypothyroidism (n=6) were included in the study. The mean age of the patients was 53.02 ± 11.9 years, and the mean BMI was 29.60 ± 3.9 kg/m2. Fifty-two (52%) patients were classified as obese. Body weight, BMI, serum TSH, ALT, Anti-TPO levels, and thyroid volume decreased significantly in the 6th-month compared to baseline values (p = 0.000; p = 0.000; p = 0.011; p = 0.022; p = 0.000, respectively). Serum anti-Tg, fT4, fT3 levels, and thyroid nodule count did not change significantly. A high agreement was found between the baseline and 6thmonth nodule counts (gamma= 0.886; p < 0.001) and the presence of multi-nodularity in the thyroid (gamma= 0.941; p < 0.001), but no significant change was observed. Anti-TPO levels showed a significant decrease in both with and without obesity groups at the end of 6 months (p = 0.003, p = 0.009, respectively). Serum TSH level decreased significantly only in non-obese subjects (p = 0.004), and thyroid volume decreased significantly only in obese subjects (p = 0.000). Our results suggest that metformin treatment significantly reduces body weight, BMI, thyroid volume, and serum TSH, ALT, and Anti-TPO levels in patients with newly diagnosed T2DM. Moreover, serum TSH levels showed a significant decrease in non-obese subjects, while thyroid volume showed a significant decrease in obese subjects.

L-Arginine-Dependent Nitric Oxide Production in the Blood of Patients with Type 2 Diabetes: A Pilot, Five-Year Prospective Study

Backgound: Type 2 diabetes mellitus (T2DM) is a major cardiovascular risk factor. Nitric oxide (NO) is one of the many molecules that regulate vascular tone, and red blood cells (RBCs) are known to play an important role in adjusting cardiac function through NO export from RBCs. Our study prospectively investigated the L-arginine (L-arg)–nitric oxide (NO) metabolic pathway in the erythrocytes and plasma of subjects with T2DM. Methods: RBCs and plasma were collected from patients with T2DM (n = 10), at first clinical onset (baseline) and after five years of disease evolution (follow-up). L-arg content was assayed by competitive enzyme-linked immunoassay. Arginase activity and nitrate/nitrite levels were measured using spectrophotometry. Results: When compared to baseline, L-arg content decreased in RBCs and remained similar in the plasma; NO production decreased in RBCs and the plasma; and arginase activity was lower in RBCs and increased in plasma. Conclusions: The L-arg/NO metabolic pathway decreases in the RBCs of patients with T2DM five years after the first clinical onset. The persistent decrease in RBCs’ arginase activity fails to compensate for the sustained decrease in RBCs’ NO production in the diabetic environment. This pilot study indicates that the NO-RBC pool is depleted during the progression of the disease in the same cohort of T2DM patients.

Prevalence of nonalcoholic fatty liver disease and liver cirrhosis in Chinese adults with type 2 diabetes mellitus.

Nonalcoholic fatty liver disease (NAFLD) and liver cirrhosis are significant clinical concerns, especially among individuals with type 2 diabetes mellitus (T2DM). However, in China, there is a paucity of reliable evidence detailing the characteristics of NAFLD and liver cirrhosis in T2DM. Furthermore, the relationship between blood glucose levels and NAFLD prevalence remains unclear. Data from the Shanghai Suburban Adult Cohort and Biobank were analyzed, including 6621 participants with T2DM. NAFLD was diagnosed by ultrasonography and liver cirrhosis was performed according to the health information systems. Logistic regression and restricted cubic spline analysis were used to explore the potential risk factors for NAFLD and liver cirrhosis. The prevalence of NAFLD was 59.36%, and liver cirrhosis was 1.43% among T2DM patients. In these patients, factors like age, being female, marital status, and obesity significantly increased the risk of NAFLD. Specifically, obesity had a strong positive association with NAFLD (odds ratio [OR] = 4.70, 95% confidence interval [CI]: 4.13-5.34). The higher glycated hemoglobin (HbA1c) quartile was associated with a heightened NAFLD risk compared to the lowest quartile (all p < .001). The HbA1c-NAFLD relationship displayed a linear that mimicked an inverted L-shaped pattern. A significant positive association existed between HbA1c levels and NAFLD for HbA1c <8.00% (OR = 1.59, 95% CI: 1.44-1.75), but this was not observed for HbA1c >8.00% (OR = 1.03, 95% CI: 0.92-1.15). Systematic screening for NAFLD is essential in T2DM patients, especially with poor glucose control and obesity in female.
