Point-of-care ultrasound can make the difference in patients with heart failure at primary care.

Background: Primary healthcare centers (PHC) play a pivotal role in the first-line management of patients with diabetes and hypertension, major risk factors for heart failure (HF) development. Point-of-care cardiac ultrasound (POCUS), integrated as an extension of the physical examination, holds significant potential to enhance diagnostic accuracy and clinical management in this setting.

Objectives: Evaluate the impact of POCUS on clinical decision-making in patients with HF and at risk of developing HF in PHC and compare POCUS findings with clinical assessment alone, conventional echocardiography, and electrocardiogram results.

A Portuguese expert panel position paper on the management of heart failure with preserved ejection fraction - Part II: Unmet needs and organization of care in Portugal.

In Portugal, a 15.2% prevalence of heart failure with preserved ejection fraction (HFpEF) was recently identified among those aged ≥50 years. HFpEF represents 90% of Portuguese heart failure patients.

PRIMARY-HF: Heart Failure Screening in Primary Care using Point-of-Care.

Introduction: Heart failure is a major health challenge with high morbidity and socioeconomic burden, especially when diagnosis is delayed. In primary care, HF detection can be challenging due to symptoms overlapping with other conditions, limited access to diagnostic tools, and resource constraints. This study explores the use of natriuretic peptides (NT-proBNP) and point-of-care ultrasound (POCUS) with artificial intelligence integration as tools to improve HF screening and management in primary care.

A Portuguese expert panel position paper on the management of heart failure with preserved ejection fraction - Part I: Pathophysiology, diagnosis and treatment.

Heart failure (HF) with preserved ejection fraction (HFpEF) affects more than 50% of HF patients worldwide, and more than 70% of HF patients aged over 65. This is a complex syndrome with a clinically heterogeneous presentation and a multifactorial pathophysiology, both of which make its diagnosis and treatment challenging. A Portuguese HF expert panel convened to address HFpEF pathophysiology and therapy, as well as appropriate management within the Portuguese context.

Moving the needle towards the democratization of echocardiography: a case report.

Background: Echocardiography has been traditionally performed in echo labs and the potential benefits of its use by primary care physicians (PCPs) are still unexplored. We present a case where POCUS (point-of-care ultrasound) was used as a complement of physical examination by a family doctor, allowing a prompt clinical decision in a heart failure (HF) patient.

Case Summary: An 85-year-old woman, living independently, asks her family doctor for a home consultation due to increasing dyspnoea.

Trimethylation of histone 3 at lysine 4 in cryopreserved bovine embryos produced in vivo with sexed semen.

The production rates of viable embryos using sexed semen through the conventional methodologies of multiple ovulation and embryo transfer are generally not satisfactory. However, the cryopreservation of these embryos is considered efficient. Knowledge of epigenetics can provide new tools or allow for adapting new protocols that could enhance the efficiency of reproductive biotechnologies.

Chemical composition and extraction yield of the extract of Origanum vulgare obtained from sub- and supercritical CO2.

In this work sub- and supercritical CO(2) were used to obtain extracts from two origanum samples, one commercial, and another cultivated under agronomic control. The experiments were performed in the temperature range of 293-313 K and from 100 to 200 bar in pressure, employing around 26 g of origanum samples. Results show that the commercial sample provides a higher yield of extract if compared to the other sample.

The effects of temperature and pressure on the characteristics of the extracts from high-pressure CO(2) extraction of Majorana hortensis Moench.

The aim of this work is to assess the influence of temperature and pressure (solvent density) on the characteristics of the essential oil obtained from high-pressure carbon dioxide extraction of marjoram (commercial marjoram samples available in the free market and Majorana hortensis Moench, cultivated in South Brazil under rigorous agronomic conditions). The extracts were analyzed in terms of the liquid yield (extract/raw material, wt/wt) and distribution of volatile chemical components. The experiments were performed in a laboratory-scale unit using the dynamic method in the temperature range of 293.
