Human Monkeypox Virus and Host Immunity: New Challenges in Diagnostics and Treatment Strategies.

The monkeypox virus (MPXV), responsible for human disease, has historically been limited to the African countries, with only a few isolated instances reported elsewhere in the world. Nevertheless, in recent years, there have been occurrences of monkeypox in regions where the disease is typically absent, which has garnered global interest. Within a period of less than four months, the incidence of MPXV infections has surged to over 48,000 cases, resulting in a total of 13 deaths. This chapter has addressed the genetics of the pox virus, specifically the human monkeypox virus, and its interaction with the immune systems of host organisms. The present chapter is skillfully constructed, encompassing diagnostic methodologies that span from traditional to developing molecular techniques. Furthermore, the chapter provides a succinct analysis of the therapeutic methods employed, potential future developments, and the various emerging difficulties encountered in illness management.

Citrus flavonoids and adhesion molecules: Potential role in the management of atherosclerosis.

Atherosclerosis as a chronic inflammatory disorder is accompanied with oxidative stress which causes a high morbidity and mortality. Adhesion molecules, including intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), P-selectin, and E-selectin, are amongst the most important contributors in atherosclerosis. In such cases, dietary interventions with functional foods containing natural antioxidant and anti-inflammatory constituents are of a great interest. Citrus fruits are rich sources of flavonoids as natural pigments with potent antioxidant and anti-inflammatory activities. This study aims to review current evidence regarding the role of citrus flavonoids in the management of atherosclerosis with a focus on their effect on adhesion molecules. Electronic databases including PubMed, Scopus, and Web of Science were searched with the names of adhesion molecules and flavonoids from inception until January 2023. The included articles highly support the beneficial effects of citrus flavonoids in preclinical models of atherosclerosis. Quercetin, naringin and naringenin, hesperidin and hesperetin, nobiletin, rutin, luteolin, apigenin, and kaempferol are the most common flavonoids in citrus fruits which could modulate adhesion molecules including ICAM-1, VCAM-1, E-selectin, and P-selectin. Additionally, markers of chronic inflammation such as interleukins, tumor necrosis factor-α, nuclear factor-κB, and nitric oxide signaling, as well as oxidative stress markers like superoxide dismutase and glutathione were all normalized upon administration of citrus flavonoids. Conclusively, this review confirms the modulatory role of flavonoids on adhesion molecules in atherosclerosis based on the preclinical evaluations. Thus, citrus fruits can be further studied in atherosclerotic patients regarding their activity in reducing adhesion molecules.

Can Hydrogen Water Enhance Oxygen Saturation in Patients with Chronic Lung Disease? A Non-Randomized, Observational Pilot Study.

BACKGROUND: Recently, chronic lung diseases have been found to be associated with marked inflammation and oxidative stress, which leads to fibrosis in the lungs and chronic respiratory failure. This study aims to determine if hydrogen-rich water (HRW) can enhance oxygen saturation among patients with chronic lung diseases. METHODS: Ten patients with chronic lung diseases due to COPD (n = 7), bronchial asthma (n = 2), and tuberculosis of the lung (n = 1) with oxygen saturation of 90-95% were provided high-concentration (>5 mM) HRW using H2-producing tablets for 4 weeks. Oxygen saturation was measured via oximeter and blood pressure via digital automatic BP recorder. RESULTS: HRW administration was associated with a significant increase in oxygen saturation (SpO2) and decrease in TBARS, MDA, and diene conjugates, with an increase in vitamin E and nitrite levels, compared to baseline levels. Physical training carried out after HRW therapy appeared to increase exercise tolerance and decrease hypoxia, as well as delay the need for oxygen therapy. CONCLUSION: Treatment with HRW in patients with hypoxia from chronic lung diseases may decrease oxidative stress and improve oxygen saturation in some patients. HRW therapy may also provide increased exercise tolerance in patients with chronic hypoxia, but further research is needed.

ASSESSMENT OF THE ASSOCIATION OF SEROTONIN TRANSPORTER GENE (5-HTTVNTR & 5-HTTLPR) POLYMORPHISM IN PATIENTS WITH FIBROMYALGIA SYNDROME.

OBJECTIVE: The aim: To study the clinical and the genetic association of 5-HTTVNTR and the 5-HTTLPR polymorphisms in women with FMS. PATIENTS AND METHODS: Materials and methods: 105 FMS patients and 105 controls were enrolled in the study. Polymerase chain method was used to analyse the 5-HTTLPR & 5-HTTVNTR gene polymorphism. The psychopathology status of the 105 FMS patients and 105 healthy controls was assessed using the Beck Depression Inventory (BDI) and the Symptom Checklist-90-Revised (SCL-90-R) questionnaires. RESULTS: Results: In FMS patients and controls, the 10/10, 10/12, and 12/12 genotypes of the 5-HTTVNTR polymorphism were found in 3.8% and 2.9%, 20% and 15.2%, and 76.28% and 81.90%, respectively. Additionally, the L/L, S/L, and S/S genotypes of the 5-HTTLPR polymorphism were found in 4.8% and 2.9%, 36.2% and 40%, 59% and 57.1%, in FMS patients and healthy controls, respectively. There were no significant differences in the frequency of genotypes between FMS patients and controls. There were no significant differences in the BDI and the SCL-90-R scores according to the serotonin transporter genotypes. CONCLUSION: Conclusions: We found no significant difference between 5-HTT gene polymorphism (5-HTTVNTR and 5-HTTLPR) and the psychiatric test results (P>0.05) in FMS patients. Hence, we conclude that serotonin gene polymorphism (5-HTTLPR & 5-HTTVNTR) is not associated with FMS in north Indian women. Our results suggests that the serotonin transporter polymorphism does not seem to be a susceptibility factor for FMS.

Role of de novo lipogenesis in inflammation and insulin resistance in Alzheimer's disease.

Patients with Alzheimer's disease (AD) display both peripheral tissue and brain insulin resistance, the later could be a potential risk factor for cognitive dysfunction. While certain degree of inflammation is required for inducing insulin resistance, underlying mechanism(s) remains unclear. Evidence from diverse research domains suggest that elevated intracellular fatty acids of de novo pathway can induce insulin resistance even without triggering inflammation; however, the effect of saturated fatty acids (SFAs) could be detrimental due the development of proinflammatory cues. In this context, evidence suggest that while lipid/fatty acid accumulation is a characteristic feature of brain pathology in AD, dysregulated de novo lipogenesis could be a potential source for lipid/fatty acid accumulation. Therefore, therapies aimed at regulating de novo lipogenesis could be effective in improving insulin sensitivity and cognitive function in patients with AD.

To Study the ß-Globin Haplotype Pattern of Descent of a Set of Linked Alleles Occurring on the Same Chromosome in the Northern Province of India.

OBJECTIVE: To study the five mutations commonly prevalent in North India, i.e., IVS-I-5 (G→C), 619 bp deletion, IVS-I-1 (G→T), codon 41/42 (-TTCT), and codon 8/9 (+G), in the beta thalassemia (ß-thalassemia) major children. The specific ß-thalassemia mutations of different haplotype patterns of the ß-globin gene cluster will also be determined. METHODS: A total of 125 children diagnosed with ß-thalassemia major visiting the Department of Pediatrics of King George's Medical University were involved in the study. As per the QIAamp (Qiagen, Hilden, Germany) manufacturer guidelines, genomic DNA was isolated from whole blood. To identify the haplotype pattern within the ß-globin gene cluster, the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis was used. The respective restriction endonucleases used were Hind III/GƔ, Hinc II/Ψß, Hinf I/ß, Ava II/ß, and BamHI for the haplotype analysis in the ß-globin pattern of descent of a set of linked alleles occurring on the same chromosome. RESULTS: Among the five common mutations, 73 patients had IVS-I-5 (G→C), 28 patients had 619 bp deletion, 17 patients had IVS-I-1 (G→T), five patients had Cd 41/42 (-TTCT), and two patients had Cd 8/9 (+G) mutations. Fifteen haplotypes (haplotypes 1-15) were identified in 125 ß-thalassemia major children. Among the five haplotypes observed in the IVS-I-5 (G→C) mutation, the H1 haplotype was most predominant with a frequency of 27.2%, followed by the H2, H4, H3, and H10 haplotypes in the given population. In 619 bp deletion, IVS-I-1 (G→T), codon 41/42, and codon 8/9, haplotype H9, H12, H11, and H5 were seen, respectively. CONCLUSION: ß-thalassemia was found to be the most common in the northern province of Uttar Pradesh. The linkage of ß-globin gene haplotypes with ß-thalassemia mutations was explored in the northern province of Uttar Pradesh. The population of different natives is being mixed up due to migration and industrialization. These were some reasons for the occurrence of haplotypic heterogeneity. This haplotype heterogeneity was correlated with the origin of these mutations found to be unlike the origin of common ones from different provinces.

UNRAVELING THE CLINICO-GENETIC ASSOCIATION OF CATECHOL-O-METHYLTRANSFERASE-RS4680 G>A GENE POLYMORPHISM IN WOMEN WITH FIBROMYALGIA SYNDROME.

OBJECTIVE: The aim: To determine the clinical and the genetic association of the COMT rs4680 SNP in women with FMS. PATIENTS AND METHODS: Materials and methods: Extracted DNA from peripheral blood samples were utilized as template for the PCR and RFLP analysis. RESULTS: Results: A significant difference was found in the distribution of the COMT genotype between FMS patients and controls (P<0.05). The frequency of GG, AG, AA genotypes were 12%, 72%, 21% in FMS patients and 32%, 62%, 11% in controls. The clinical features of FMS reveal that FIQR and the severity of pain measured by VAS were significantly associated with the COMT rs4680 SNP (P=0.042; P=0.016). The co-dominant model for GG verse v. AG genotype (P=0.004) and AG v. AA genotype (P=0.002) has shown to be high risk for FMS. An increased risk of FMS in the dominant model for (AG+AA) v. GG genotype (P=0.001) and no significant difference was found between (GG+AG) v. AA genotype (P=0.08) in the recessive model. The result indicated that A allele considerably increase the risk of FMS (P=0.004) in comparison to the G allele. CONCLUSION: Conclusions: AA genotype and A allele of the COMT rs4680 SNP were significantly associated with severity in FMS patients and also plays a significant role in the clinical manifestation of this disease.

High Exogenous Antioxidant, Restorative Treatment (Heart) for Prevention of the Six Stages of Heart Failure: The Heart Diet.

The exact pathophysiology of heart failure (HF) is not yet known. Western diet, characterized by highly sweetened foods, as well as being rich in fat, fried foods, red meat and processed meat, eggs, and sweet beverages, may cause inflammation, leading to oxidative dysfunction in the cardiac ultra-structure. Oxidative function of the myocardium and how oxidative dysfunction causes physio-pathological remodeling, leading to HF, is not well known. Antioxidants, such as polyphenolics and flavonoids, omega-3 fatty acids, and other micronutrients that are rich in Indo-Mediterranean-type diets, could be protective in sustaining the oxidative functions of the heart. The cardiomyocytes use glucose and fatty acids for the physiological functions depending upon the metabolic requirements of the heart. Apart from toxicity due to glucose, lipotoxicity also adversely affects the cardiomyocytes, which worsen in the presence of deficiency of endogenous antioxidants and deficiency of exogenous antioxidant nutrients in the diet. The high-sugar-and-high-fat-induced production of ceramide, advanced glycation end products (AGE) and triamino-methyl-N-oxide (TMAO) can predispose individuals to oxidative dysfunction and Ca-overloading. The alteration in the biology may start with normal cardiac cell remodeling to biological remodeling due to inflammation. An increase in the fat content of a diet in combination with inducible nitric oxide synthase (NOSi) via N-arginine methyl ester has been found to preserve the ejection fraction in HF. It is proposed that a greater intake of high exogenous antioxidant restorative treatment (HEART) diet, polyphenolics and flavonoids, as well as cessation of red meat intake and egg, can cause improvement in the oxidative function of the heart, by inhibiting oxidative damage to lipids, proteins and DNA in the cell, resulting in beneficial effects in the early stage of the Six Stages of HF. There is an unmet need to conduct cohort studies and randomized, controlled studies to demonstrate the role of the HEART diet in the treatment of HF.

Relationship Between Vitamin D Receptor Gene BsmI Polymorphism and Fibromyalgia Syndrome.

Purpose Vitamin D receptor (VDR) has been proposed as a possible marker for fibromyalgia syndrome (FMS). The purpose of this study is to characterize the expression pattern of BsmI polymorphism (rs1544410) in the VDR gene in women with FMS and the genotype-phenotype association. Methods A total of 105 FMS patients and 105 controls were included in this study. VDR gene BsmI polymorphism was assessed by polymerase chain reaction (PCR) and restriction fragment length polymerase (RFLP) method. Results There was no significant difference in the frequency distribution of both genotypes and alleles for VDR gene BsmI polymorphism between FMS patients and controls (p>0.05). The frequencies of BB, Bb, and bb in the VDR gene BsmI polymorphism were 19%, 43%, and 37% in patients, while in controls were 22.9%, 55.2%, and 21.9%. However, we did not find any significant association between the clinical symptoms of this disease and VDR BsmI genotypes among FMS patients (p>0.05). Conclusions The relationship between the VDR gene BsmI polymorphism and FMS could not be determined in this study. However, further studies with a larger sample size may be required to show a relation between the VDR gene BsmI polymorphism and FMS.

EVALUATION OF COVID-19 VACCINES EFFICACY IN IRAQI PEOPLES.

OBJECTIVE: The aim: The present study was carried out on patients recovered from COVID-19, including those patients who have taken vaccine and those who have not. PATIENTS AND METHODS: Materials and methods: The patients were recruited via an online panel and surveyed at different regions of Iraq from June 1, 2021, to August 30, 2021. RESULTS: Results: Our results demonstrated that the highest percentage of people recommended Pfizer vaccine followed by Sinopharm, while AstraZeneca vaccine was least recommended. CONCLUSION: Conclusions: The efficacy of different vaccines differed significantly; the highest effectiveness was observed with Pfizer vaccine followed by AstraZeneca and Sinopharm with effectiveness ranging from 94%, 89%, and 74%, respectively. Further, the highest percentage of re-infected patients was observed with Sinopharm vaccine followed by Astra Zeneca and Pfizer vaccine, respectively. Also, the highest percent of re-infection with masking used was seen in the case of Sinopharm vaccine followed by AstraZeneca and Pfizer vaccine. Although, we observed that post-vaccination symptoms were lowest than pre-vaccination symptoms, the percent of asymptomatic cases post-vaccination was highest than pre-vaccination cases for all vaccines.

Why and How the Indo-Mediterranean Diet May Be Superior to Other Diets: The Role of Antioxidants in the Diet.

The Seven Countries Study showed that traditional Japanese and Mediterranean diets are protective against cardiovascular diseases (CVDs). The Japanese diet is considered the healthiest because it provides Japanese populations with the highest longevity and health. DASH and Mediterranean-style diets are also considered healthy diets, although the Indo-Mediterranean-style diet may provide better protective effects among patients with CVDs compared to other diets. The concept of the Indo-Mediterranean type of diet was developed after examining its role in the prevention of CVDs in India, the value of which was confirmed by a landmark study from France: the Lyon Heart Study. These workers found that consuming an alpha-linolenic acid-rich Mediterranean-style diet can cause a significant decline in CVDs and all-cause mortality. Later in 2018, the PREDIMED study from Spain also reported that a modified Mediterranean-style diet can cause a significant decline in CVDs, type 2 diabetes mellitus (T2DM), and cancer. The Indo-Mediterranean diet may be superior to DASH and Mediterranean diets because it contains millets, porridge, and beans, as well as spices such as turmeric, cumin, fenugreek, and coriander, which may have better anti-inflammatory and cardioprotective effects. These foods are rich sources of nutrients, flavonoids, calcium, and iron, as well as proteins, which are useful in the prevention of under- and overnutrition and related diseases. It is known that DASH and Mediterranean-style diets have a similar influence on CVDs. However, the Indo-Mediterranean-style diet may be as good as the Japanese diet due to improved food diversity and the high content of antioxidants.

Pre-heart failure at 2D- and 3D-speckle tracking echocardiography: A comprehensive review.

Chronic heart failure (CHF) has different stages and includes pre-HF (PHF), a state of high risk of developing myocardial dysfunction and advanced CHF. Some major behavioral risk factors of PHF might predispose to biological risk factors such as obesity, diabetes mellitus, dyslipidemia, hypertension, myocardial infarction, and cardiomyopathy. These risk factors damage the myocytes leading to fibrosis, apoptosis, cardiac hypertrophy, along with alterations in cardiomyocyte' size and shape. A condition of physiological subcellular remodeling resulting into a pathological state might be developed, conducting to PHF. Both PHF and heart failure (HF) are associated with the activation of phospholipases and protease, mitochondrial dysfunction, oxidative stress and development of intra-cellular free Ca2+  [Ca2+ ]i overloading to an elevation in diastolic [Ca2+ ]i . Simultaneously, cardiac gene expression is activated leading to further molecular, structural and biochemical changes of the myocardium. The sub-cellular remodeling may be intimately involved in the transition of cardiac hypertrophy to heart failure. 2D- and 3D-speckle tracking echocardiography (STE) have been used to quantify regional alterations of longitudinal strain and area strain, through their polar projection, which permits a further assessment of both sites and degrees of myocardial damage. The examination of strain can identify sub-clinical cardiac dysfunction or cardiomyocyte remodeling. During remodeling of the myocardium cardiac strain is attenuated, therefore it is an indicator of disease assessment.

Dietary Approaches to Stop Hypertension via Indo-Mediterranean Foods, May Be Superior to DASH Diet Intervention.

Western-type diet with high salt and sugar, sedentary behavior, obesity, tobacco and alcoholism are important risk factors for hypertension. This review aims to highlight the role of western diet-induced oxidative stress and inflammation in the pathogenesis of hypertension and the role of various types of diets in its prevention with reference to dietary approaches to stop hypertension (DASH) diet. It seems that it is crucial to alter the western type of diet because such diets can also predispose all CVDs. Western diet-induced oxidative stress is characterized by excessive production of reactive oxygen species (ROS) with an altered oxidation-reduction (redox) state, leading to a marked increase in inflammation and vascular dysfunction. Apart from genetic and environmental factors, one important cause for differences in the prevalence of hypertension in various countries may be diet quality, deficiency in functional foods, and salt consumption. The role of the DASH diet has been established. However, there are gaps in knowledge about the role of some Indo-Mediterranean foods and Japanese foods, which have been found to decrease blood pressure (BP) by improving vascular function. The notable Indo-Mediterranean foods are pulses, porridge, spices, and millets; fruits such as guava and blackberry and vegetables, which may also decrease BPs. The Japanese diet consists of soya tofu, whole rice, in particular medical rice, vegetables and plenty of fish rich in fish oil, fish peptides and taurine that are known to decrease BPs. Epidemiological studies and randomized, controlled trials have demonstrated the role of these diets in the prevention of hypertension and metabolic diseases. Such evidence is still meager from Japan, although the prevalence of hypertension is lower (15-21%) compared to other developed countries, which may be due to the high quality of the Japanese diet. Interestingly, some foods, such as berries, guava, pumpkin seeds, carrots, soya beans, and spices, have been found to cause a decrease in BPs. Omega-3 fatty acids, fish peptide, taurine, dietary vitamin D, vitamin C, potassium, magnesium, flavonoids, nitrate and l-arginine are potential nutrients that can also decrease BPs. Larger cohort studies and controlled trials are necessary to confirm our views.

Altered pro-inflammatory and anti-inflammatory plasma cytokines levels in children with Down's syndrome: A meta-analysis.

BACKGROUND: Down syndrome (DS) is the commonest chromosomal anomalies at birth. DS is portrayed by the event of extra complete/deficient duplicate of chromosome number 21 (trisomy 21). Around the world, this disordered influencing roughly 1 out of 1000 infants. Pro-inflammatory and anti-inflammatory cytokines engaged with a few physiological procedures involving the guideline of inflammatory reactions. In DS kids, the creation of few important inflammatory and anti-inflammatory cytokines is altered. Different investigations shows that the cytokines are dysregulated in patients with DS. In this study, we led a meta-analysis to evaluate the connections of pro-inflammatory and anti-inflammatory cytokine changes in youngsters with DS patients. METHODOLOGY: We searched PubMed, Google and Web of Science for studies in exploring the association of pro-inflammatory and anti-inflammatory serum level with DS patients. Total 10 studies were included in the meta-analysis. The random effects were used to analyze the pooled data. All statistical tests were two-sided. RESULTS: High circulating level of serum MCP-1 was significantly associated with DS [Cohen's d = 143.91 95% confidence interval (CI) =110.38-177.43]. However, the other circulating cytokines IL-2 and IL-17 level were lower whereas IL-13 level was higher but not significantly different in DS as contrasted to healthy controls. The heterogeneity level was higher in IL-2, IL-13 and IL-17 cytokines. CONCLUSION: This meta-analysis shows that the higher circulating level of MCP-1 was associated with DS.

Molecular hydrogen as an adjuvant therapy may be associated with increased oxygen saturation and improved exercise tolerance in a COVID-19 patient.

Administration of molecular hydrogen dissolved in water to patient with COVID-19-like symptoms may improve oxygen levels and exercise capacity.

Association of KDR rs1870377 genotype with clopidogrel resistance in patients with post percutaneous coronary intervention.

BACKGROUND: Clopidogrel is an antiplatelet therapy that is widely used in pre and post percutaneous (PCI) coronary intervention procedures to prevent platelet aggregation and stent restenosis. However, there is a wide inter-individual variation in clopidogrel response and some patients showed resistance against the activity of Clopidogrel. Kinase insert domain receptor (KDR) gene is responsible for the transcription of vascular endothelial growth factor receptor 2 (VEGFR2) that plays a major role in the cardiovascular diseases (CVDs) and platelet aggregation. The aim of this study was to find out the association of KDR rs1870377 genotype with clopidogrel resistance (CR) in CVD patients, of Iraqi Arabic origin, hospitalized for elective PCI. MATERIALS AND METHODS: This study was a case-control study with a total of 324 PCI patients. Those patients were classified into 213 patients with non-clopidogrel resistant and 111 patients with CR, depending on the analysis of platelet activity phenotype after clopidogrel administration. KDR rs1870377 was genotyped for all patients using polymerase chain reaction-restriction fragment length polymorphism technique and confirmed by DNA Sänger sequencing through applying Biosystems Model (ABI3730x1). RESULTS: KDR rs1870377 SNP is strongly associated (Chi-sqaure, p vale <0.05) with CR under dominant, co-dominant and recessive models. Additionally, A allele in the rs1870377 SNP may have an impact on the serum levels of VEGFR2 and low density lipoprotein. CONCLUSIONS: KDR rs1870377 SNP is a potential genetic biomarker of CR among CVD patients of Iraqi Arabic origin. Further clinical studies, with larger sample, are required to confirm the findings of this study.

Anti-Atherosclerotic and Anti-Inflammatory Effects of Curcumin on Hypercholesterolemic Male Rabbits.

Curcumin has a potent antioxidant and anti-inflammatory properties that may suppress inflammatory component of atherosclerosis. It has been demonstrated that curcumin derivatives can reduce the formation of arterial fatty streaks in cholesterol-fed rabbits. Therefore in this study we evaluated the protective effects of Curcumin on the progression of atherosclerosis. 20 mature rabbits were included for this study; they were randomly divided into four groups each of 5. Group 1: (normal control) were fed corn pellets diet and tab water, group 2: (high cholesterol diet control) were kept on cholesterol rich diet (2% cholesterol) and tab water. Group 3: (cholesterol and rosuvastatin treated group) were kept on cholesterol rich diet (2% cholesterol) and 2.5 mg/kg/day Rosuvastatin dispersed in DW and given orally, group 4: (cholesterol and curcumin treated group) were kept on cholesterol rich diet (2% cholesterol) and 0.2% curcumin added with corn pellets. The study continued for 12 weeks then assessment of serum level of high sensitive C-reactive protein, ICAM1, VCAM1 and PCSK9 was carried out at the end of the study. Total antioxidant activity of curcumin was also determined. Histopathological examination of aortic tissues for atherosclerotic changes was also carried out. Atherogenic (cholesterol rich diet) induced an increment in serum level of TC, LDL, VLDL and TG with concomitant decrement in serum level of HDL and increased atherogenic index. Treatment with curcumin produced substantial reduction in serum TC, LDL, TG with no effect on HDL level thus decreased atherogenic index. Rabbits treated with curcumin showed a significant reduction in the serum level of high sensitive C-reactive protein, ICAM1, VCAM, PCSK9 serum expression and aortic total antioxidant capacity. Curcumin has a potent anti-inflammatory and anti- oxidant effects against atherosclerosis so exerts a protective role by decreasing lipid oxidation and inflammatory markers.

Effects of empagliflozin on proinflammatory cytokines and other coronary risk factors in patients with type 2 diabetes mellitus: A single-arm real-world observation.

OBJECTIVE: This single-arm real-world observation aims to examine the effects of empagliflozin (EMPA) on coronary risk factors among subjects with known diabetes. MATERIALS AND METHODS: Records of 63 subjects with type 2 diabetes mellitus, receiving EMPA were drawn for this study. Of 63 patients with diabetes, 6 were excluded, and the remaining 57 received EMPA (25 mg/day) for 24 weeks. Clinical data, dietary intakes, and physical activity were assessed by validated questionnaires. RESULTS: Treatment with EMPA was associated with significant decline in fasting and 2-hour post-prandial blood glucose and Hb1c indicating that this agent has potential antidiabetic effects. Pro-inflammatory cytokines; C-reactive protein, TNF-α, and interleukin-6 showed significant reduction after treatment with EMPA, compared to baseline levels. Apart from these changes, parameters of oxidative stress, thiobarbituric acid reactive substances, malondialdehyde, and diene conjugates as well as uric acid, showed a significant decline with an increase in antioxidant vitamins A, E, and C and beta-carotene as well as nitrite. There was a significant decline in serum uric acid, systolic and diastolic blood pressures, and angiotensin-converting enzyme (ACE), with a non-significant reduction in body weight and body mass index as well as in waist circumference of modest significance, after intervention of 12 weeks compared to baseline levels. Total cholesterol, VLDL cholesterol and triglycerides showed non-significant decline compared to baseline levels. CONCLUSION: It is possible that EMPA administration can cause a significant decline in pro-inflammatory cytokines along with blood glucose, Hb1c, oxidative stress, uric acid, blood pressures, and ACE with an increase in antioxidant vitamins and nitrite. Randomized, controlled intervention trials would be necessary to confirm our findings.

Effect of iron and folate supplementation on Pb levels in pregnant anemic women: a prospective study.

There are few reports revealing association between iron intake and environmental lead exposure during pregnancy. Therefore, the present study was undertaken to investigate the effect of iron supplementation on biochemical modulation of certain lead toxicity markers associated with pregnancy. Iron and folic acid supplementations were given to 250 pregnant anemic women (mild = 100, moderate = 100 and severe = 50) and 100 age matched nonanemic pregnant women as controls for 100 days. Lead (Pb) toxicity markers, enzymatic and nonenzymatic antioxidant were estimated as per standard protocols. The levels of Pb, serum transferrin receptors (sTfR), zinc protoporphyrin (ZPP), δ-aminolevulinic acid (δ-ALA, both in blood and urine) were found significantly increased in all pretreated subjects and these were decreased after oral iron supplementation. Iron-deficient pregnant women reflected a significant increase in lipid peroxide levels (LPO) and protein carbonyl levels (PC) which were found to be further increased after iron supplementation. The levels of iron (Fe), haemoglobin (Hb), ferritin, delta aminolevulinic acid dehydratase (δ-ALAD), catalase (CAT), superoxide dismutase (SOD), and reduced glutathione levels (GSH) were significantly decreased in pretreated groups and these parameters were found significantly increased in all supplemented subjects after treatment. Antioxidant vitamins viz. C and E were found significantly decreased in all post treated groups. Our observation suggests that recommended iron dose is not only effective for blood indices parameters, but it also decreases Pb concentrations in the blood during pregnancy. However, further studies with larger sample size are needed to confirm these findings.

Trimetazidine Improves the Outcome of EECP Therapy in Patients with Refractory Angina Pectoris.

INTRODUCTION: Cardiovascular disease (CAD) associated with death and disability remains a serious medical problem. In some patients the initial clinical coronary artery disease presentation is stable angina pectoris. AIM: The aim of the study was to evaluate the effect of EECP therapy with or without trimetazidine (TMZ) in patients with refractory angina via modulating peripheral monocyte expression of Toll like receptor2 (TLR2) and its downstream signaling. METHODS: This is a double-blind randomized prospective study in which 88 stable refractory angina patients allocated into two groups, Enhanced External Counter Pulsation (EECP) group: included 44 patients with stable refractory angina, and were treated with EECP-Therapy. TMZ-EECP group: included 44 patients with stable refractory angina, we gave TMZ 35 mg twice daily in addition to EECP-Therapy. RESULTS: TLR2 expression in peripheral monocyte investigated by flow cytometry and 8-iso-prostaglandin F2ß (8-iso-PGF2 ß), interleukin1ß (IL-1ß), heat shock protein 60 (HSP60) and monocytes chemoattractant protein-1(MCP-1) were also measured before the EECP-therapy and before giving TMZ to patients, and after 35 hours of EECP treatment (7 consecutive weeks). Inhibition in TLR2 expression in peripheral monocyte was observed among the EECP group (P<0.05). Inflammatory cytokine MCP-1 was remarkably decreased in both study groups but (heat shock protein 60 (HSP60), MCP-1 and interleukin-1ß (IL-1ß)) significantly decreased levels were observed among the TMZ-EECP group (P<0.05). Also, the oxidative stress biomarker 8-iso-prostaglandin F2ß (8-iso-PGF2ß) was decreased in both study groups but significantly decreased levels were observed among the TMZ-EECP group (P<0.05). TMZ and EECP therapy in patients with stable refractory angina remarkably decreased the inflammatory markers HSP60, MCP-1 and IL-1ß in serum levels also the decreased levels were found in serum levels of oxidative stress marker 8-iso-PGF2ß serum level. CONCLUSION: EECP-therapy decreased the expression of TLR2 on peripheral monocytes in patients with chronic stable refractory angina which yield improvement in the quality of patients' life by decreasing the frequency of angina episodes, decreasing the Short-acting nitrate use and change the exercise tolerance and distance.
