Background: Cardiovascular diseases (CVD) remain the leading cause of mortality worldwide. Medication adherence is an important issue in managing chronic CVD, directly influencing outcomes and healthcare costs.

Objectives: This systematic review, supported by the Brazilian Society of Cardiology, evaluates the impact of poor adherence to cardiovascular medications on critical clinical outcomes such as death and cardiovascular events.

Despite the noteworthy advancements and the introduction of new technologies in diagnostic tools for cardiovascular disorders, the electrocardiogram (ECG) remains a reliable, easily accessible, and affordable tool to use. In addition to its crucial role in cardiac emergencies, ECG can be considered a very useful ancillary tool for the diagnosis of many non-cardiac diseases as well. In this narrative review, we aimed to explore the potential contributions of ECG for the diagnosis of non-cardiac diseases such as stroke, migraine, pancreatitis, Kounis syndrome, hypothermia, esophageal disorders, pulmonary embolism, pulmonary diseases, electrolyte disturbances, anemia, coronavirus disease 2019, different intoxications and pregnancy.

Article Synopsis
  • - Optimal risk assessment for preventing cardiovascular issues remains difficult, with existing guidelines not effectively identifying many at-risk individuals, causing delays in necessary preventive measures until they experience serious events.
  • - Cardiovascular imaging is becoming essential for accurately categorizing patients by their risk profiles, which helps tailor treatment strategies for those with increased cardiovascular risks.
  • - Current treatment approaches for atherosclerotic cardiovascular disease (ASCVD) lack individualization; research shows significant variation in risks, emphasizing the need for personalized strategies and further studies to refine risk definitions and enhance treatment for high-risk subgroups.

Background And Objectives: This study aimed to identify CSF proteomic signatures characteristic of Parkinson disease (PD) and evaluate their clinical utility.

Methods: This observational study used data from the Parkinson's Progression Markers Initiative (PPMI), which enrolled patients with PD, healthy controls (HCs), and non-PD participants carrying , , and/or pathogenic variants (genetic prodromals) at international sites. Study participants were chosen from PPMI enrollees based on the availability of aptamer-based CSF proteomic data, quantifying 4,071 proteins, and classified as patients with PD without , , and/or pathogenic variants (nongenetic PD), HCs, patients with PD carrying the aforementioned pathogenic variants (genetic PD), or genetic prodromals.

The pathogenesis and clinical heterogeneity of Parkinson's disease (PD) have been evaluated from molecular, pathophysiological, and clinical perspectives. High-throughput proteomic analysis of cerebrospinal fluid (CSF) opened new opportunities for scrutinizing this heterogeneity. To date, this is the most comprehensive CSF-based proteomics profiling study in PD with 569 patients (350 idiopathic patients, 65 GBA + mutation carriers and 154 LRRK2 + mutation carriers), 534 controls, and 4135 proteins analyzed.

Article Synopsis
  • - A study in Brazil was conducted to evaluate how heart failure disease management program (DMP) components affect care and clinical decisions, involving cardiologists surveyed from various public and private centers.
  • - Results showed that public HF-DMPs provided significantly more dedicated services, educational programs, written discharge instructions, and multidisciplinary care compared to private DMPs; whereas, non-multidisciplinary programs had fewer educational initiatives and monitoring practices.
  • - The survey revealed that physicians often adjusted or started new medications primarily during patient hospitalizations, highlighting the importance of care settings in patient management.

Background: Observational studies have highlighted an association between serum uric acid (SUA) levels and cardiovascular risk factors. Despite the growing body of evidences, several studies were conducted in older individuals or in carriers of diseases susceptible to affect SUA levels and cardiometabolic risk markers.

Objective: To evaluate the relationship of SUA with body adiposity, metabolic profile, oxidative stress, inflammatory biomarkers, blood pressure and endothelial function in healthy young and middle-aged adults.

Objectives: Obstructive sleep apnea (OSA) is a risk factor for cardiovascular disease (CVD), the main cause of mortality in chronic kidney disease (CKD). Although the prevalence of OSA in patients with CKD has not been established, a few studies suggest that it is higher than in the general population, potentially increasing the risk for CVD. Obesity increases the risk, whereas sarcopenia has been suggested as a consequence of OSA in the general population.

Background: Omalizumab, a humanized recombinant monoclonal anti-IgE antibody, proved to be effective in patients with chronic spontaneous urticaria (CSU), including severe and treatment-refractory CSU. Here, we report omalizumab's effect on gene expression in skin biopsies from CSU patients enrolled in a double-blind, placebo-controlled study.

Methods: Chronic spontaneous urticaria patients (18-75 years) were randomized to either 300 mg omalizumab (n = 20) or placebo (n = 10) administered s.

Nutritional intervention for weight loss is one of the treatment options for obstructive sleep apnoea (OSA) in patients with overweight or obesity. However, the effects of moderate energy restriction on OSA severity are not yet known. The present study aimed to evaluate the effects of moderate energy restriction on OSA severity and CVD risk factors in obese patients with OSA.

Background: Eosinophilic esophagitis (EoE) is a chronic allergic disease with limited treatment options.

Objective: We evaluated QAX576, an mAb against IL-13, in the treatment of patients with EoE.

Methods: Patients (18-50 years) with proton pump inhibitor-resistant esophageal eosinophilia received intravenous QAX576 (6 mg/kg) or placebo (2:1) at weeks 0, 4, and 8 and were followed for 6 months.

Objective: To test whether long-term antihypertensive treatment with metoprolol succinate (a β₁-adrenoceptor blocker) or olmesartan medoxomil (an angiotensin II AT₁-receptor blocker) reverses microvascular dysfunction in hypertensive patients.

Methods: This study included 44 hypertensive outpatients and 20 age and sex-matched healthy controls. We used skin capillaroscopy to measure capillary density and recruitment at rest and during PORH.

Understanding the biological pathways critical for common neurofibromatosis type 1 (NF1) peripheral nerve tumours is essential, as there is a lack of tumour biomarkers, prognostic factors and therapeutics. We used gene expression profiling to define transcriptional changes between primary normal Schwann cells (n = 10), NF1-derived primary benign neurofibroma Schwann cells (NFSCs) (n = 22), malignant peripheral nerve sheath tumour (MPNST) cell lines (n = 13), benign neurofibromas (NF) (n = 26) and MPNST (n = 6). Dermal and plexiform NFs were indistinguishable.

Rationale: Global gene expression analysis provides a comprehensive molecular characterization of non-small cell lung cancer (NSCLC).

Objectives: To evaluate the feasibility of integrating expression profiling into routine clinical work-up by including both surgical and minute bronchoscopic biopsies and to develop a robust prognostic gene expression signature.

Methods: Tissue samples from 41 chemotherapy-naive patients with NSCLC and 15 control patients with inflammatory lung diseases were obtained during routine clinical work-up and gene expression profiles were gained using an oligonucleotide array platform (NovaChip; 34'207 transcripts).
