  • Ventilator-associated pneumonia (VAP) frequently affects patients with severe COVID-19 who are on mechanical ventilation, prompting this study to examine how corticosteroids might influence VAP risk.
  • A multicenter study analyzed data from 545 patients in 36 ICUs to determine if corticosteroid use impacted VAP incidence, finding that the relationship varied after 48 hours of mechanical ventilation.
  • Overall, no significant link was established between corticosteroid treatment and VAP, though the effect seemed to shift over time during the ICU stay.

Background: Coronavirus disease 2019 (COVID-19) can be associated with life-threatening organ dysfunction due to septic shock, frequently requiring intensive care unit (ICU) admission, respiratory and vasopressor support. Therefore, clear clinical criteria are pivotal for early recognition of patients more likely to need prompt organ support. Although most patients with severe COVID-19 meet the Sepsis-3.

Sepsis is a life-threatening syndrome characterized by a dysregulated host response to an infection that may evolve rapidly into septic shock and multiple organ failure. Management of sepsis relies on the early recognition and diagnosis of infection and the providing of adequate and prompt antibiotic therapy and organ support. A novel protein biomarker, the pancreatic stone protein (PSP), has recently been studied as a biomarker of sepsis and the available evidence suggests that it has a higher diagnostic performance for the identification of infection than the most used available biomarkers and adds prognostic value.

Article Synopsis
  • - This study aimed to compare the incidence of invasive pulmonary aspergillosis (IPA) in critically ill patients with COVID-19 versus those with influenza, using data from a large European cohort that included over 1,000 patients on mechanical ventilation for pneumonia.
  • - Results showed that the incidence of putative IPA was significantly lower in the COVID-19 group (2.5%) compared to the influenza group (6%), indicating that COVID-19 patients had a reduced risk for this fungal infection.
  • - The study also found that having putative IPA was linked to increased 28-day mortality and longer ICU stays, affirming its severity, but overall the incidence of IPA was low across both patient groups.

The Armenian highlands encompasses rugged and environmentally diverse landscapes and is characterized by a mosaic of distinct ecological niches and large temperature gradients. Strong seasonal fluctuations in resource availability along topographic gradients likely prompted Pleistocene hominin groups to adapt by adjusting their mobility strategies. However, the role that elevated landscapes played in hunter-gatherer settlement systems during the Late Pleistocene (Middle Palaeolithic [MP]) remains poorly understood.

Community-acquired pneumonia (CAP) is a leading cause of morbidity and mortality despite adequate antibiotic therapy. It is the single most common cause of infection-related mortality in the United States. An exaggerated host inflammatory response can potentially be harmful to both the lung and host, and has been associated with treatment failure and mortality.

Purpose Of Review: The successful treatment of surgical fungal infections depends of a timely and adequate source control alongside with the use of prompt systemic antifungals. The main challenge of antifungal use in critically ill surgical patients is to find a balance between rational versus indiscriminate use in order to accomplish an antifungal stewardship program.

Recent Findings: Surgical fungal infections represent an important burden in the daily clinical activity in many ICUs.

Quality surgical practice is a fundamental subject in health institutions, and it is important to understand the structural and organizational conditions of the operating room (OR). The present exploratory study sought to understand the motivations that underlie the choice of surgeons for the best healthcare unit to perform surgery, as well as the characteristics of those professionals regarding age, years of work experience, and sex. A questionnaire survey was administered to a convenience sample of 99 surgeons, 67.

Ventilator-associated pneumonia (VAP) is a common infection in intensive care units (ICUs) but its clinical definition is neither sensitive nor specific and lacks accuracy and objectivity. New defining criteria were proposed in 2013 by the National Healthcare Safety Network (NHSN) in order to more accurately conduct surveillance and track prevention progress. Although there is a consistent trend towards a decrease in VAP incidence during the last decade, significant differences in VAP rates have been reported and are persistently lower in NHSN and other American reports (0.

Biomarkers as C-reactive protein (CRP) and procalcitonin (PCT) emerged as tools to help clinicians to diagnose infection and to properly initiate and define the duration of antibiotic therapy. Several randomized controlled trials, including adult critically ill patients, showed that PCT-guided antibiotic stewardship was repeatedly associated with a decrease in the duration of antibiotic therapy with no apparent harm. There are however some relevant limitations in these trials namely the low rate of compliance of PCT-guided algorithms, the high rate of exclusion (without including common clinical situations and pathogens) and the long duration of antibiotic therapy in control groups.

Background: Post-traumatic stress disorder (PTSD) may be associated with chronic immune dysregulation and a proinflammatory state. Among HIV-infected individuals, PTSD is associated with greater morbidity and mortality, but the association with immune dysfunction has not been evaluated. This study explores the association between PTSD and selected markers of inflammation and immune activation in a cohort of HIV-infected, virally-suppressed individuals.

Influenza pneumonia is associated with high number of severe cases requiring hospital and intensive care unit (ICU) admissions with high mortality. Systemic steroids are proposed as a valid therapeutic option even though its effects are still controversial. Heterogeneity of published data regarding study design, population demographics, severity of illness, dosing, type and timing of corticosteroids administered constitute an important limitation for drawing robust conclusions.
