Article Synopsis
  • Nosocomial pneumonia, which is a lung infection that people can get while in the hospital, leads to higher rates of sickness and death and costs a lot to treat, especially in ICUs (Intensive Care Units).
  • Most cases of this type of pneumonia happen in patients on ventilators, which helps them breathe.
  • The PneumoINSPIRE study is looking at how this pneumonia is diagnosed and treated in ICUs from over 20 countries to gather important information about it and improve future care.

Article Synopsis
  • Omentin-1 is an adipokine with anti-inflammatory properties that plays a significant role in sepsis, and its levels were studied in critically ill patients to assess their relationship with disease severity and prognosis.
  • Patients with sepsis showed markedly elevated serum omentin-1 levels compared to healthy controls, which increased further after one week, with higher levels noted in those with septic shock and in nonsurvivors.
  • The study concluded that elevated omentin-1 levels at sepsis onset and after one week are independent predictors of 28-day mortality, highlighting its potential as a marker for assessing sepsis severity.

Oxidative stress is considered pivotal in the pathophysiology of sepsis. Oxidants modulate heat shock proteins (Hsp), interleukins (IL), and cell death pathways, including apoptosis. This multicenter prospective observational study was designed to ascertain whether an oxidant/antioxidant imbalance is an independent sepsis discriminator and mortality predictor in intensive care unit (ICU) patients with sepsis ( = 145), compared to non-infectious critically ill patients ( = 112) and healthy individuals ( = 89).

Pulmonary hypertension (PH) development remains a significant cardiovascular complication of haemoglobinopathies, severely affecting the morbidity and mortality of such patients. According to the 5th World Symposium on PH, PH related with chronic haemolytic anaemias is classified in group 5, mainly due to the multifactorial pathophysiology of PH in this patient population. There are no clear guidelines regarding the management of PH in patients with haemoglobinopathies; the use of specific pulmonary arterial hypertension (PAH) therapy in patients with β-thalassaemia and PH is based on data derived from other forms of PH, expert opinion and small series or case reports.

Many pathophysiologic processes of pulmonary arterial hypertension (PAH), namely, excess vasoconstriction, vascular remodeling and in situ thrombosis, involve the coagulation cascade, and more specifically, platelets. The aim of this study was to globally assess coagulation processes in PAH, by using non-conventional hemostatic tests, along with markers of platelet activation and endothelial dysfunction. We studied 44 new PAH patients (22 with idiopathic PAH and 22 with connective tissue disease) and 25 healthy controls.

In light of the accumulating evidence on the negative predictive value of soluble urokinase plasminogen activator receptor (suPAR), a group of experts from the fields of intensive care medicine, emergency medicine, internal medicine and infectious diseases frame a position statement on the role of suPAR in the screening of patients admitted to the emergency department. The statement is framed taking into consideration existing publications and our own research experience. The main content of this statement is that sUPAR is a non-specific marker associated with a high negative predictive value for unfavourable outcomes; levels < 4 ng/ml indicate that it is safe to discharge the patient, whereas levels > 6 ng/ml are an alarming sign of risk for unfavourable outcomes.

Ventilator-associated tracheobronchitis (VAT) is an infection commonly affecting mechanically ventilated intubated patients. Several studies suggest that VAT is associated with increased duration of mechanical ventilation (MV) and length of intensive care unit (ICU) stay, and a presumptive increase in healthcare costs. Uncertainties remain, however, regarding the cost/benefit balance of VAT treatment.

Antimicrobial agents are currently the mainstay of treatment for bacterial infections worldwide. However, due to the increased use of antimicrobials in both human and animal medicine, pathogens have now evolved to possess high levels of multi-drug resistance, leading to the persistence and spread of difficult-to-treat infections. Several current antibacterial agents active against Gram-positive bacteria will be rendered useless in the face of increasing resistance rates.
