Introduction: Proportional Pulse Pressure (PPP) is a significant risk indicator in heart failure. PPP is a simple, inexpensive and easily measurable clinical index. This non-invasive test provides useful prognostic information for patients with heart failure with reduced ejection fraction (EF) particularly in those with an EF < 30% where lower proportional pulse pressure independently predicts mortality.
Methods: A prospective observational study involving 150 patients with reduced ejection fraction was done. Detailed history, clinical examination and parameters like pulse pressure, proportional pulse pressure were evaluated and correlated with ejection fraction.
Results: The mean age of the patients was 58.99 ± 11.03 years and the majority of the study participants (57.33 %) were between 45 and 65 years of age. The most common etiology of heart failure (HF) was coronary heart disease in this study (76%). Proportional Pulse pressure showed significant association with ejection fraction. The specificity for detecting heart failure was more for proportional pulse pressure and systolic blood pressure (95 % each).
Conclusion: Proportional Pulse Pressure may help to identify HF patients who present with low cardiac output, low ejection fraction, and worse prognosis. Our current observations reinforce the importance of clinically based skills that must not be forgotten when managing HF.

Fluid administration is widely used to treat hypotension in patients undergoing veno-venous extracorporeal membrane oxygenation (VV-ECMO). However, excessive fluid administration may lead to fluid overload can aggravate acute respiratory distress syndrome (ARDS) and increase patient mortality, predicting fluid responsiveness is of great significance for VV-ECMO patients. This prospective single-center study was conducted in a medical intensive care unit (ICU) and finally included 51 VV-ECMO patients with ARDS in the prone position (PP).

The Tibetan Plateau is home to numerous glaciers that are important for freshwater supply and climate regulation. These glaciers, which are highly sensitive to climatic variations, serve as vital indicators of climate change. Understanding glacier-fed hydrological systems is essential for predicting water availability and formulating climate adaptation strategies.

B-type natriuretic peptide (BNP) levels accurately reflect the degree of cardiac overload in heart failure. Considering cardiac morphology and intracardiac pressure, including the left ventricular end-systolic volume index (LVESVI) and left ventricular end-diastolic volume index (LVEDVI), is essential for cardiac overload assessment. These indexes influence plasma BNP levels, and high heart rate is likely associated with cardiac morphology.

Background: Delayed onset muscle soreness (DOMS) is a well-established phenomenon characterized by ultrastructural muscle damage that typically develops following unfamiliar or high-intensity exercise. DOMS manifests with a constellation of symptoms, including muscle tenderness, stiffness, edema, mechanical hyperalgesia, and a reduced range of joint motion. In recent years, the application of blood flow restriction (BFR) has garnered attention for its potential impact on DOMS.

Background: Previous research in adults has suggested that healthy dietary patterns could be an effective strategy for blood pressure (BP) control. However, during adolescence, the scientific literature examining this relationship is scarce and controversial since inverse and null associations have been reported. Thus, the aim of our study was to analyze the relationship between the level of adherence to the Mediterranean diet (MD) and consumption of fresh fruits and vegetables at baseline with changes in BP over a two-year period during adolescence.
