Regulatory role of peroxynitrite in advanced glycation end products mediated diabetic cardiovascular complications

The Advanced Glycation End Products(AGE)binding with its receptor can increase reactive oxygen species(ROS)generation through specific signaling mediators.The effect of superoxide(O2-)and O2-mediated ROS and reactive nitrogen species depends on their concentration and location of formation.Nitric oxide(NO)has anti-inflammatory and anticoagulant properties and a vasodilation effect,but NO can be deactivated by reacting with O_(2)^(-).This reaction between NO and O2-produces the potent oxidant ONOO−.Therefore,ONOO-'s regulatory role in AGEs in diabetic cardiovascular complications must considered as a regulator of cardiovascular complications in diabetes.

Cardiovascular complications following medical termination of pregnancy: An updated review

BACKGROUND Around 1 million cases of medical termination of pregnancy(MTP)take place yearly in the United States of America with around 2 percent of this population developing complications.The cardiovascular(CVD)complications occurring post MTP or after stillbirth is not very well described.AIM To help the reader better understand,prepare,and manage these complications by reviewing various cardiac comorbidities seen after MTP.METHODS We performed a literature search in PubMed,Medline,RCA,and google scholar,using the search terms“abortions”or“medical/legal termination of pregnancy”and“cardiac complications”or“cardiovascular complications”.RESULTS The most common complications described in the literature following MTP were infective endocarditis(IE)(n=16),takotsubo cardiomyopathy(TTC)(n=7),arrhythmias(n=5),and sudden coronary artery dissection(SCAD)(n=4).The most common valve involved in IE was the tricuspid valve in 69%(n=10).The most observed causative organism was group B Streptococcus in 81%(n=12).The most common type of TTC was apical type in 57%(n=4).Out of five patients de veloping arrhythmia,bradycardia was the most common and was seen in 60%(3/5)of the patients.All four cases of SCAD-P type presented as acute coronary syndrome 10-14 d post termination of pregnancy with predominant involvement of the right coronary artery.Mortality was only reported following IE in 6.25%.Clinical recovery was reported consistently after optimal medical management following all these complications.CONCLUSION In conclusion,the occurrence of CVD complications following pregnancy termination is infrequently documented in the existing literature.In this review,the most common CVD complication following MTP was noted to be IE and TTC.

Advanced glycation end products:Key mediator and therapeutic target of cardiovascular complications in diabetes

The incidence of type 2 diabetes mellitus is growing in epidemic proportions and has become one of the most critical public health concerns.Cardiovascular complications associated with diabetes are the leading cause of morbidity and mortality.The cardiovascular diseases that accompany diabetes include angina,myocardial infarction,stroke,peripheral artery disease,and congestive heart failure.Among the various risk factors generated secondary to hyperglycemic situations,advanced glycation end products(AGEs)are one of the important targets for future diagnosis and prevention of diabetes.In the last decade,AGEs have drawn a lot of attention due to their involvement in diabetic pathophysiology.AGEs can be derived exogenously and endogenously through various pathways.These are a nonhomogeneous,chemically diverse group of compounds formed nonenzymatically by condensation between carbonyl groups of reducing sugars and free amino groups of protein,lipids,and nucleic acid.AGEs mediate their pathological effects at the cellular and extracellular levels by multiple pathways.At the cellular level,they activate signaling cascades via the receptor for AGEs and initiate a complex series of intracellular signaling resulting in reactive oxygen species generation,inflammation,cellular proliferation,and fibrosis that may possibly exacerbate the damaging effects on cardiac functions in diabetics.AGEs also cause covalent modifications and cross-linking of serum and extracellular matrix proteins;altering their structure,stability,and functions.Early diagnosis of diabetes may prevent its progression to complications and decrease its associated comorbidities.In the present review,we recapitulate the role of AGEs as a crucial mediator of hyperglycemia-mediated detrimental effects in diabetes-associated complications.Furthermore,this review presents an overview of future perspectives for new therapeutic interventions to ameliorate cardiovascular complications in diabetes.

Maternal-Fetal Pregnancy Complications of in Minors Raped with or without Physical Restraint in Eastern Democratic Republic of Congo

Introduction: Pregnancy resulting from rape is a public health and sexual and reproductive health issue, especially among minors. Rape can be perpetrated with or without physical restraint. The objective of the present study is to highlight the prevalence of physical coercion leading to pregnancy and the associated maternal-fetal complications. Methodology: This was a comparative descriptive and analytical cross-sectional study of complications associated with post-rape pregnancy by physical restraint among minors who were treated at the General Reference Hospital of Panzi over a two-year period from June 2020 to June 2022. A total of 140 minor survivors of violence with pregnancy were included in the study. Data were collected using a questionnaire, coded and analyzed in Excel and XLSTAT version 2014. Results: The prevalence of physical constraints was 65%. After mulltivariate analyses, denial of pregnancy (ORa: 9.64 95% CI: 1.1 - 81.2;p-value: 0.0370), attempted abortion (ORa: 56.1 95% CI: 1.5 - 2027.6;p-value: 0.0278) and agitation during delivery (ORa: 88.7 95% CI: 4.5 - 1715;p-value: 0.0030) were the complications associated with pregnancy in minors who experienced physical restraint rape. In addition, BMI was a factor in reducing the risk of physical restraint rape at the ORa of 0.5054 [0.3;0.8];p 0.006). Conclusion: Pregnancy among minors is a reality and occurs in a situation of physical coercion in the eastern Democratic Republic of Congo. These pregnancies are often associated with complications that require an intensive management system since they can jeopardize the maternal-fetal prognosis of minors.

Asymmetric dimethylarginine, a biomarker of cardiovascular complications in diabetes mellitus

Cardiovascular(CV) complications are an essential causal element of prospect in diabetes mellitus(DM), with carotid atherosclerosis being a common risk factor for prospective crisis of coronary artery diseases and/or cerebral infarction in DM subjects. From another point of view, asymmetric dimethylarginine(ADMA) has been established as an inhibitor of endogenous nitric oxide synthesis and the relationship between ADMA and arteriosclerosis has been reported. In our study with 87 type 2 DM(T2DM) patients, we have examined whether ADMA and other CV risk factors are the useful predictors of DMCV complications. After the measurement of the respective CV risk factors, we have followed the enrolled T2 DM patients for 5 years. We have finally analyzed 77 patients. DMCV complications developed in 15 cases newly within 5 years, and 4 cases recurred. The concentrations of ADMA in plasma were markedly more elevated in 19 DM patients with CV complications than in 58 DM patients without CV complications. Urinary albumin(U-Alb), mean intimal-medial thickness(IMT) and ankle brachial index(ABI) were also higher in patients with CV complications. Multiple regression analyses showed that U-Alb had an influence on the high level of ADMA(standardized β = 6.59, P = 0.00014) independently of age, systolic BP, fibrinogen, mean IMT, plaque score, and ABI. The review indicates what is presently known regarding plasma ADMA that might be a new and meaningful biomarker of CV complications in DM subjects.

Prevention of macrovascular complications in patients with type 2 diabetes mellitus: Review of cardiovascular safety and efficacy of newer diabetes medications

Lack of conclusive beneficial effects of strict glycemic control on macrovascular complications has been very frustrating for clinicians involved in care of patients with diabetes mellitus (DM). Highly publicized controversy surrounding cardiovascular (CV) safety of rosiglitazone resulted in major changes in United States Food and Drug Administration policy in 2008 regarding approval process of new antidiabetic medications, which has resulted in revolutionary data from several large CV outcome trials over the last few years. All drugs in glucagon-like peptide-1 receptor agonist (GLP-1 RA) and sodium-glucose cotransporter-2 (SGLT-2) inhibitor classes have shown to be CV safe with heterogeneous results on CV efficacy. Given twofold higher CV disease mortality in patients with DM than without DM, GLP-1 RAs and SGLT-2-inhibitors are important additions to clinician’s armamentarium and should be second line-therapy particularly in patients with T2DM and established atherosclerotic CV disease or high risks for CV disease. Abundance of data and heterogeneity in CV outcome trials results can make it difficult for clinicians, particularly primary care physicians, to stay updated with all the recent evidence. The scope of this comprehensive review will focus on all major CV outcome studies evaluating CV safety and efficacy of GLP-1 RAs and SGLT-2 inhibitors.

Risk of cardiovascular,cardiac and arrhythmic complications in patients with non-alcoholic fatty liver disease

Non-alcoholic fatty liver disease(NAFLD)has emerged as a public health problem of epidemic proportions worldwide.Accumulating clinical and epidemiological evidence indicates that NAFLD is not only associated with liver-related morbidity and mortality but also with an increased risk of coronary heart disease(CHD),abnormalities of cardiac function and structure(e.g.,left ventricular dysfunction and hypertrophy,and heart failure),valvular heart disease(e.g.,aortic valve sclerosis)and arrhythmias(e.g.,atrial fibrillation).Experimental evidence suggests that NAFLD itself,especially in its more severe forms,exacerbates systemic/hepatic insulin resistance,causes atherogenic dyslipidemia,and releases a variety of pro-inflammatory,pro-coagulant and pro-fibrogenic mediators that may play important roles in the pathophysiology of cardiac and arrhythmic complications.Collectively,these findings suggest that patients with NAFLD may benefit from more intensive surveillance and early treatment interventions to decrease the risk for CHD and other cardiac/arrhythmic complications.The purpose of this clinical review is to summarize the rapidly expanding body of evidence that supports a strong association between NAFLD and cardiovascular,cardiac and arrhythmic complications,to briefly examine the putative biological mechanisms underlying this association,and to discuss some of the current treatment options that may influence both NAFLD and its related cardiac and arrhythmic complications.

Frequency of the Cardiovascular Complications during the Chronic Renal Insufficiency with the Service of Nephrology of the National Hospital Donka

Introduction: Cardiovascular disease has become a major concern for the nephrologist as it is the leading cause of morbidity and mortality in patients with chronic kidney disease, and affects all stages of the disease, including the earliest stages of the disease. The goal of this work was to determine the frequency of cardiovascular complications during chronic kidney failure. Patients and methods: This was a six-month, descriptive cross-sectional study from March 01 to August 31, 2018. It covered all patients with chronic kidney disease hospitalized in the ward during the study period. Included were all chronic kidney failure patients with at least one cardiac and/or vascular complication diagnosed either on clinical examination, and/or paraclinical examination (Electrocardiogram or cardiac ultrasound, vessel echodoppler, scan). Results: During the study period, 84 out of 378 patients or 22.22% had at least one cardiovascular complication. Cardiovascular complications were hypertrophy of the left ventricle with 49/84 (44 at Electrocardiogram and 5 at cardiac echodoppler), valvulopathy with 33.33%, stroke with 50% of cases, obliterating arterial disease of the lower limbs 25%, hypokinetic dilated cardiomyopathy with 9/36 cases and pericarditis with 2/36. Conclusion: Cardiovascular complications affect both sexes and all ages. They were dominated by enlarged left ventricle, valvulopathy and dilated cardiomyopathy.

Comparing the incidence of major cardiovascular events and severe microvascular complications in patients with type 2 diabetes mellitus:A systematic review and meta-analysis

BACKGROUND Type 2 diabetes mellitus(T2DM)causes both macrovascular and microvascular complications.However,currently,selection of glycemic measures and their thresholds to diagnose T2DM,and efficacy outcomes in evaluation of anti-diabetic drugs is predominantly informed by the relation of T2DM to microvascular complications.We can be severely mistaken on T2DM by neglecting macrovascular complications which are generally more severe,if they also occur more commonly than microvascular complications.AIM To compare the incidence of major cardiovascular events(MACEs)and severe microvascular complications(SMICs)in T2DM patients.METHODS MEDLINE,EMBASE,and Cochrane Central Register of Controlled Trials were searched from inception to September 2017.Cohort studies or trials of T2DM patients aged 18 years or older that reported incidence of both MACEs and SMICs were included.MACEs were defined as nonfatal myocardial infarction and stroke,and cardiovascular death,while SMICs included serious retinopathy,nephropathy and diabetic disorder.The relative risk(RR)was estimated as the incidence of MACEs divided by that of SMICs in same patients and combined with meta-analysis in a random-effect model.RESULTS Twelve studies with a total of 16 cohorts and 387376 patients were included,and the combined RR was 2.02(95%CI:1.46–2.79).The higher incidence of MACEs remained in various subgroup and sensitivity analyses.CONCLUSION Patients with T2DM are much more likely to develop MACEs than SMICs.By taking more serious consequences and relatively higher incidence into consideration,macrovascular complications deserve more emphasis in developing the diagnostic criteria of T2DM and in evaluating the efficacy of antidiabetic drugs.

Prevelance of Pregnancy Complications among Women Aged 15 - 49 in Oğuzeli, Turkey

As maternal deaths have decreased worldwide, increasing attention has been placed on the study of severe obstetric complications, such as hemorrhage, eclampsia, and obstructed labor, to identify where improvements can be made in maternal health. The objective of this study was to determine pregnancy complications and prenatal care among women aged 15 - 49 in Oğuzeli, Turkey, and to provide data for prevention in the field. This descriptive, cross-sectional study was conducted between February and May 2013 in Oğuzeli distinct, Turkey. The total women registered to family doctors in Oğuzeli was listed and, 470 women were selected using a stratified and simple random sampling technique. Pregnancy complications were asked for the last pregnancy of each women. Of the women, 23.9% (n = 109) declared that they experienced pregnancy complications during their pregnancies. The most frequent problems were anemia (11.1%) hypertension (3.7%) and diabetes mellitus (2.4%) respectively. Women having chronic diseases before their pregnancy were more likely to have pregnancy complications compared to healthy women (p = 0.005). The mean number of prenatal care among women having pregnancy complications was 5.47 ± 3.57, while it was 3.84 ± 3.00 among healthy women (p = 0.000). Women having chronic diseases should be handled carefully and, pregnancy should be delayed until the chronic disease’s remission. Family planning in primary care is the key measure to archive this. Early diagnosis of hypertension among young women is highly important for the women’s and infants’s health during pregnancy, and for the women’s future heath. During prenatal care, women should be trained about correct eating habits and activity.

Birth outcomes and pregnancy complications of women with uterine leiomyoma—a population-based case-control study

Objective Uterine leiomyoma is not a rare pathological condition in pregnant women;thus the aim of the study was to evaluate the recent progress in the treatment of these pregnant women on the basis of the association of leiomyoma in pregnancy (LP) with pregnancy complications and birth outcomes including structural birth defects, i.e. congenital abnormalities (CA) in the offspring. Design Cases with CA and matched controls without CA in the population-based Hungarian Case-Control Surveillan- ce System of Congenital Abnormalities (HCC SCA) were evaluated. Only women with prospectively and medically recorded LP in prenatal maternity logbook and medically recorded birth outcomes (gestational age, birth weight, CA) were included to the study. Setting the HCCSCA, 1980-1996 contained 22,843 cases with CA and 38,151 matched controls without CA. Population Hungarian pregnant women and their informative offspring: live births, stillbirths and prenatally diagnosed malformed fetuses. Methods Comparison of birth outcomes of ca- ses with matched controls and pregnancy com- plications of pregnant women with or without LP. Main outcome measures Pregnancy complications, mean gestational age at delivery and birth weight, rate of preterm birth, low birthweight, CA. Results A total of 34 (0.15%) cases had mothers with LP compared to 71 (0.19%) controls. There was a higher incidence of threatened abortion, placental disorders, mainly abruption placentae and anaemia in mothers with LP. There was no significantly higher rate of preterm birth in the newborns of women with LP but their mean birth weight was higher and it associated with a higher rate of large birthweight newborns. A higher risk of total CA was not found in cases born to mothers with LP (adjusted OR with 95% CI = 0.7, 0.5-1.1), the spe- cified groups of CAs were also assessed versus controls, but a higher occurrence of women with LP was not revealed in any CA group. Con- clusions Women with LP have a higher risk of threatened abortion, placental disorders and anaemia, but a higher rate of adverse birth outcomes including CAs was not found in their offspring.

Pregnancy complications effect on the nickel content in maternal blood,placenta blood and umbilical cord blood during pregnancy

BACKGROUND Nickel(Ni)may accumulate in the human body and has biological toxicity and carcinogenicity.Ni has an extensive impact on the health of pregnant women and fetuses during gestation.AIM To evaluate Ni exposure in pregnant women in Kunming,Yunnan Province,China;to describe the distribution of Ni in the maternal-fetal system and placental barrier function;and to investigate the effect of Ni exposure on fetal health in mothers with pregnancy complications.METHODS Seventy-two pregnant women were selected using a case-control design.The women were divided into two groups:The control group(no disease;n=29)and the disease group[gestational diabetes(GDM),hypertensive disorder complicating pregnancy(HDCP),or both;n=43].The pregnant women in the disease group were further divided as follows:14 cases with GDM(GDM group),13 cases with HDCP(HDCP group)and 16 cases with both GDM and HDCP(disease combination group).Basic information on the pregnant women was collected by questionnaire survey.Maternal blood,placenta blood and cord blood were collected immediately after delivery.The Ni content in paired samples was determined using inductively coupled plasma mass spectrometry.RESULTS Compared to the control group,age was higher and body mass index was greater in pregnant women in the disease groups(28.14±2.54 vs 28.42±13.89,P<0.05;25.90±3.86 vs 31.49±5.30,P<0.05).The birth weights of newborns in the HDCP group and the control group were significantly different(2.52±0.74 vs 3.18±0.41,P<0.05).The content of Ni in umbilical cord blood in the entire disease group was higher than that in the control group(0.10±0.16 vs 0.05±0.07,P<0.05).CONCLUSION In the maternal-fetal system of women with pregnancy complications,the barrier effect of the placenta against Ni is weakened,thus affecting healthy growth of the fetus in the uterus.

Diabetes, sleep apnea, obesity and cardiovascular disease: Why not address them together?

Obesity, sleep apnea, diabetes and cardiovascular diseases are some of the most common diseases encountered by the worldwide population, with high social and economic burdens. Significant emphasis has been placed on obtaining blood pressure, body mass index, and placing importance on screening for signs and symptoms pointing towards cardiovascular disease. Symptoms related to sleep, or screening for sleep apnea has been overlooked by cardiac, diabetic, pulmonary and general medicine clinics despite recommendations for screening by several societies. In recent years, there is mounting data where obesity and obstructive sleep apnea sit at the epicenter and its control can lead to improvement and prevention of diabetes and cardiovascular complications. This editorial raises questions as to why obstructive sleep apnea screening should be included as yet another vital sign during patient initial inpatient or outpatient visit.

PROPHYLACTIC AND THERAPEUTIC EFFECTS OF ACUPUNCTURE ON SIMPLE OBESITY COMPLICATED BY CARDIOVASCULAR DISEASES

In order to understand the prophylactic-therapeutic effects of acupuncture and moxibustion insimple obesity complicated by cardiovascular diseases,we have observed in 102 cases the changesof pathogenetic and hazardous factors and the regulating function of vegetative nerves oncardiovascular activities.The results showed that the therapeutic effect of acupuncture andmoxibustion was good with a total effective rate of 88.24%.At the same time,acupuncture andmoxibustion were found to have a benign conversion effect on the loin hip ratio(the pathogeneticfactor),the arteriosclerotic index(the hazardous factor),and the vegetative nerve function ofregulating the heart and blood vessels(the equilibrium indices of the vegetative nervous system).All this suggests that acupuncture is a treatment of choice for obesity and an important methodof preventing and treating complicating cardiovascular diseases.

Diabetic patients with chronic kidney disease: Non-invasive assessment of cardiovascular risk

The prevalence and burden of diabetes mellitus and chronic kidney disease on global health and socioeconomic development is already heavy and still rising.Diabetes mellitus by itself is linked to adverse cardiovascular events,and the presence of concomitant chronic kidney disease further amplifies cardiovascular risk.The culmination of traditional(male gender,smoking,advanced age,obesity,arterial hypertension and dyslipidemia)and non-traditional risk factors(anemia,inflammation,proteinuria,volume overload,mineral metabolism abnormalities,oxidative stress,etc.)contributes to advanced atherosclerosis and increased cardiovascular risk.To decrease the morbidity and mortality of these patients due to cardiovascular causes,timely and efficient cardiovascular risk assessment is of huge importance.Cardiovascular risk assessment can be based on laboratory parameters,imaging techniques,arterial stiffness parameters,ankle-brachial index and 24 h blood pressure measurements.Newer methods include epigenetic markers,soluble adhesion molecules,cytokines and markers of oxidative stress.In this review,the authors present several non-invasive methods of cardiovascular risk assessment in patients with diabetes mellitus and chronic kidney disease.

J24924 possesses cardiovascular and renal protective effects on pristane-induced lupus through inhibition of RhoA/Rho kinase pathway in mice

OBJECTIVE To explore whether J24924could prevent the development of pristane-induced lupus in a mouse model,and whether it could protect renal and lower the cardiovascular risk.METHODS The effect of J24924 was assessed in female BALB/c mice intraperitoneal injected with 0.5 m L of pristane,and serum autoantibodies were tested every month,blood pressure wasmeasured every 2 months,while serum inflammatory markers,spleen pathologic characteristics,renal injury and vascular function were observed at 6 month.RESULTS J24924 could decrease serum autoantibodies and serum inflammatory markers in the SLE mice and improved the spleen pathologic characteristics,and at the same time improved the renal injury and decreased inflammatory responses in kidneys,reduced blood pressure and improved vascular endothelial function.Western blotting assays revealed that inhibition for the activation of NF-κB and Rho/ROCKs signaling pathways and the downstream signaling molecules might be the potential mechanisms of J24924.CONCLUSION Our findings suggestthat therapy of J24924 may be a strategy to prevent SLE and ameliorate associated kidney and cardiovascular complications.

Post-Procedure Mortality after Cardiovascular Treatment Procedures in Patients with Pneumoconiosis

Pneumoconiosis (PNC) is a major occupational disease that develops as a result of occupational exposure to dust via inhalation. In addition to its harmful effects on the respiratory system, PNC can increase vulnerability to coronary heart disease (CHD)—the leading cause of death in the United States and in the world. Currently, two types of cardiovascular intervention procedures for CHD treatment are percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG). The objective of this study was to investigate comparative effectiveness of the two major cardiovascular intervention procedures—PCI and CABG—in PNC patients with CHD. Data from 1094 hospitalizations of adult patients with PNC and CHD (CHD-PNC patients) and 534,120 hospi-talizations of CHD patients without PNC (CHD-nonPNC) were investigated. Adjusted odds ratios for in-hospital death in relation to the type of procedure, adjusted for patient socio-demographic and clinical characteristics and hospital characteristics, were calculated using multivariable logistic regression. Men constituted 97.8% of CHD-PNC patients and 68.6% of CHD-nonPNC patients. Within the CHD-PNC group, crude (unadjusted) in-hospital mortality after CABG and PCI did not differ significantly (1.35% vs. 2.00%, p = 0.425) and remained insignificant in the multivariable analysis, adjusted for patient and hospital characteristics (adjusted OR = 0.714, 95% CI 0.220 - 2.323, p = 0.576). But in the CHD-nonPNC group, in-hospital mortality after CABG was significantly higher than after PCI both in crude analysis (2.83% vs. 1.28%,

Risk Factors of Postpartum Cardiovascular Disease in Patients with Gestational Diabetes Mellitus

Objective:To investigate the risk factors of postpartum cardiovascular disease in patients with gestational diabetes mellitus(GDM).Methods:From December 2020 to December 2021,pregnant women who underwent 75-g oral glucose tolerance test(OGTT)between 24 and 28 weeks of gestation and were diagnosed with GDM were selected as the research subjects.These women were followed-up after delivery.Results:The average fasting plasma glucose(FPG)levels of these women were 6.25±1.36 mmol/L before discharge and 5.01±1.45 mmol/L at 42 days after delivery;the average 2-hour plasma glucose(2hPG)levels were 11.23±2.01 mmol/L before discharge and 7.98±1.23 mmol/L at 42 days after delivery;the average insulin levels were 8.36±1.98 mmol/L before discharge and 2.98±1.36 mmol/L at 42 days after delivery.There were 46 patients with postpartum cardiovascular disease,with an incidence rate of 22.89%.Conclusion:By improving the postpartum management of patients,the weight of GDM patients can be better controlled,their insulin sensitivity can be increased,and the occurrence of glucose and lipid metabolism disorders can be reduced.

Research progress on the correlation between metabolic-associated fatty liver disease and cardiovascular disease

Metabolisc-associated fatty liver disease(MAFLD)is a multi-system disease in which cardiovascular disease plays an important role and is considered the main cause of death.Notably,cardiovascular disease events in young patients with MAFLD have attracted extensive attention.This article reviews the research progress on the correlation between MAFLD and cardiovascular disease.
