Article Synopsis
  • Obesity triggers inflammation in the body by activating specific immune cells called adipose tissue macrophages (ATMs), shifting their types from beneficial to harmful.
  • In healthy individuals, ATMs in fat tissue generally promote tissue health (M2 type), but in obese people, there’s an increase in inflammatory ATMs (M1 type), especially in subcutaneous fat (SAT).
  • The study identified key markers for these macrophage types and found that while the overall count of beneficial ATMs increased in SAT of obese individuals, changes in visceral fat (VAT) were more complex, with a mix of both harmful and helpful macrophages present.

Background And Objective: Diabetes mellitus can affect the lungs, in its various structures and functions. Current research is being conducted to establish the clinical impact of hyperglycaemia on lung function. The objective of this study is to determine if the glycaemic state (euglycaemic, prediabetes or diabetes) is associated with a decrease in lung volume, determined by spirometry.

Aims: To assess the prevalence of autoantibodies (Aab) to insulin (IAA), glutamic acid decarboxylase 65 (GADA) and insulinoma antigen 2 (IA-2A), as well as human leukocyte antigen (HLA) class II alleles, in first degree relatives (FDR) of Mexican patients with type 1 diabetes (T1D), and to explore whether these parameters mirror the low incidence of T1D in the Mexican population.

Methods: Aab titers were determined by ELISA in 425 FDR, 234 siblings, 40 offspring and 151 parents of 197 patients with T1D. Typing of HLA-DR and -DQ alleles was performed in 41 Aab-positive FDR using polymerase chain reaction with allele-specific oligotyping.

Background: Metabolic syndrome is a condition that predisposes to cardiovascular disease and diabetes mellitus. In addition, it can have effects over neoplastic pathologies, liver and pulmonary function. Our objective is to analyze the effect of the metabolic syndrome and its components on pulmonary function.

Unlabelled: Hyperuricemia leads to insulin resistance, whereas insulin resistance decreases renal excretion of uric acid, both mechanisms link elevated serum uric acid with metabolic syndrome. The aim of this study is to evaluate the probability for the development of metabolic syndrome in low-income young adults with hyperuricaemia.

Methods: We evaluated 103 patients less than 40 years of age, from a low-income population, and without history of cardiovascular disease, in all of them the presence of metabolic syndrome was assessed in accordance with the International Diabetes Federation criteria.

Background: Type 2 diabetes mellitus is commonly associated with hypertension; the standard oral glucose load is an independent risk factor for cardiovascular disease. The aim of this research is to show the prevalence of abnormal glucose tolerance in hypertensive patients with normal fasting glucose.

Methods: We enrolled 65 hypertensive non diabetic patients with fasting glucose < 100 mg/dL.

Background: Because hypertension and depression share common pathways, it is possible that each disease has an impact on the natural history of the other.

Objective: To determinate whether depression influences blood pressure control in hypertensive patients.

Methods: Forty hypertensive patients undergoing antihypertensive treatment, excluding beta-blockers and central-acting agents, self-measured their blood pressure several times a day for three days using a validated, commercially available device.

Two major subsets of human Mo are identified based on CD14 and CD16 expression: the classical CD16(-) Mo and the minor CD14(+)CD16(+) Mo. In vitro studies suggested distinct function and differentiation potential for each cell population. However, the in vivo relevance of these findings remains unclear.

Introduction: Adiponectin is secreted from adipose tissue and exhibits a protective effect against cardiovascular disease; plasma adiponectin concentrations are decreased in type 2 diabetic and in hypertensive patients.

Objective: The aim of this study was to compare the effect of trandolapril (T) and its fixed-dose combination with verapamil (FDTV) on adiponectin levels in hypertensive type 2 diabetic patients.

Methods: A total of 40 type 2 diabetic patients with never-treated hypertension were randomly assigned to two groups.

Article Synopsis
  • - The study focuses on the connection between circulating soluble adhesion molecules and atherosclerosis in hypertensive type-2 diabetic patients, highlighting the significant role of inflammation.
  • - Researchers measured levels of three molecules (VCAM-1, ICAM-1, E-selectin) and examined the thickness of carotid arteries to assess atherosclerosis in 30 patients.
  • - Results showed a notable correlation between ICAM-1 levels and carotid artery thickness, suggesting ICAM-1 may be a key factor in atherosclerosis among this patient group, while VCAM-1 and E-selectin showed no correlation.

A 39-year-old patient diagnosed two years previously with Marfan Syndrome (MS) and thoraco-abdominal aneurysm, both presented with the following symptoms: occasional mild effort dyspnea and thoracic pain. The patient started her current illness at 28 weeks of pregnancy with an exacerbation of a deep, oppressive thoracic pain and orthopnea. The echocardiogram showed a 10 cm diameter aortic aneurysm with involvement of the aortic root, tho-racoabdominal and dissection.

Background And Aim: Endothelial dysfunction in hypertensive type-2 diabetic patients is associated with increased levels of circulating soluble adhesion molecules (SAM). SAM participate in the development of diabetic macroangiopathy and microangiopathy. The aim of this study was to compare the effect of trandolapril (T) and its fixed-dose combination with verapamil (FDTV) on SAM levels in hypertensive type-2 diabetic patients.

Background: Endothelial dysfunction is a common feature in type 2 diabetic patients and is associated with inflammation, increased levels of circulating soluble adhesion molecules, and urinary albumin excretion. The aim of this study was to evaluate the role of circulating soluble adhesion molecules in the development of albuminuria.

Material/methods: Thirty normotensive type-2 diabetic patients and 30 non-diabetic normotensive subjects were studied.

Article Synopsis
  • About 70% of patients with high blood pressure require multiple medications for control, and a two-drug therapy is recommended for those with stage 2 hypertension.
  • This study assessed the effectiveness and safety of a fixed-dose combination of trandolapril and verapamil in 40 Mexican patients who were not adequately managed on their existing single-drug treatment.
  • Results indicated a significant reduction in blood pressure, with 75% of patients achieving their target levels, and the treatment was generally well-tolerated with minimal side effects.

This paper sought to determine if the fixed-dose combination of trandolapril and verapamil is effective in the treatment of hypertensive obese patients resistant to monotherapy. Thirty-six hypertensive obese patients uncontrolled by monotherapy were given the combination of trandolapril-verapamil (2/180 mg) for 12 weeks. Before and after taking the drug, they self-measured their blood pressure.

Objective: To compare the effect of fixed-dose trandolapril-verapamil (FDTV) with that of trandolapril on proteinuria in normotensive, type 2 diabetic patients.

Research Design And Methods: A total of 60 normotensive, type 2 diabetic patients with 24-h proteinuria >300 mg were randomly assigned to two groups for open-label treatment. One group received 2 mg trandolapril/180 mg verapamil FDTV once daily; the other group received 2 mg trandolapril once daily.
