Article Abstract
Echocardiographic measurements are used in critical care to evaluate volume status and cardiac performance. Mean systemic filling pressure and global heart efficiency measures intravascular volume and global heart function. This prospective study conducted in fifty haemodynamically stabilized, mechanically ventilated patients investigated relationships between static echocardiographic variables and estimates of global heart efficiency and mean systemic filling pressure. Results of univariate analysis demonstrated weak correlations between left ventricular end-diastolic volume index (r = 0.27, p = 0.04), right atrial volume index (rho = 0.31, p = 0.03) and analogue mean systemic filling pressure; moderate correlations between left ventricular ejection fraction (r = 0.31, p = 0.03), left ventricular global longitudinal strain (r = 0.36, p = 0.04), tricuspid annular plane systolic excursion (rho = 0.37, p = 0.01) and global heart efficiency. No significant correlations were demonstrated by multiple regression. Mean systemic filling pressure calculated with cardiac output measured by echocardiography demonstrated good agreement and correlation with invasive techniques (bias 0.52 ± 1.7 mmHg, limits of agreement -2.9 to 3.9 mmHg, r = 0.9, p < 0.001). Static echocardiographic variables did not reliably reflect the volume state as defined by estimates of mean systemic filling pressure. The agreement between static echocardiographic variables of cardiac performance and global heart efficiency lacked robustness. Echocardiographic measurements of cardiac output can be reliably used in calculation of mean systemic filling pressure.

Importance: Nitric oxide deficiency may contribute to exercise intolerance in patients with heart failure with preserved ejection fraction (HFpEF). Prior pilot studies have shown improvements in exercise tolerance with single-dose and short-term inorganic nitrate administration.
Objective: To assess the impact of chronic inorganic nitrate administration on exercise tolerance in a larger trial of participants with HFpEF.

Drug reaction with eosinophilia and systemic symptoms (DRESS syndrome) is a rare and potentially life-threatening condition. Symptoms typically manifest two to eight weeks after exposure to an offending agent, such as anticonvulsants and antibiotics. Clinical features include fever, morbilliform rash, eosinophilia, lymphadenopathy, and, in severe cases, multiorgan dysfunction, including interstitial nephritis, hepatitis, and pneumonitis.

Article Synopsis
- - Negative pressure breathing (NPBin) is a technique that lowers pressure in the respiratory tract during inhalation, aiming to boost blood flow to the heart and counteract fluid shifts in space.
- - This study analyzed the effects of NPBin for 25 minutes at pressure reductions of -10 to -25 cmHO, using various non-invasive measurement techniques to assess changes in circulation and respiration in healthy volunteers.
- - Results showed that NPBin increased tidal volume and decreased respiratory rate without significantly affecting overall minute ventilation, while circulatory parameters showed increased amplitude during breathing cycles, indicating a complex interaction between respiration and circulation.

Background: The term 'Missed Nursing Care' (MNC) refers to any aspect of nursing care that is not delivered, partially delivered, or delayed. MNC has significant negative consequences, including adverse patient outcomes, safety risks, and decreased job satisfaction. While extensively studied in hospitals, MNC in community healthcare settings, remains under-researched, especially in Italy.
