Respiratory complications are important causes of mortality in severe acute pancreatitis. We analyzed the pleuropulmonary complications that occurred in a series f 63 patients with severe acute pancreatitis. The most frequent were respiratory failure (52.4%) and bronchopulmonary infection (33.3%), both associated with sepsis and a high mortality rate. The initial laboratory workup included serial arterial blood gases and chest roentgenogram within the first 24 hours. The latter was useful to predict mortality. The tracheobronchial cultures isolated only enteral bacteriae. We conclude that pleuropulmonary complications are clearly related to the outcome of severe acute pancreatitis, specially when associated to sepsis.

Background And Aims: In cirrhosis, some patients display acute encephalopathy without hyperammonemia (NonHep E) which is not considered as overt hepatic encephalopathy (OHE). We aimed to assess the prevalence and characteristics of NonHep E and OHE in cirrhotic patients displaying acute encephalopathy, assess their respective prognosis and compare it to other causes of acute decompensation (AD) with/without hyperammonemia.
Approach And Results: We conducted a retrolective analysis from a prospective cohort of patients hospitalized for AD.

Amidst the ongoing COVID-19 pandemic, the imperative of our time resides in crafting stratagems of utmost precision to confront the relentless SARS-CoV-2 and quell its inexorable proliferation. A paradigm-shifting weapon in this battle lies in the realm of nanoparticles, where the amalgamation of cutting-edge nanochemistry begets a cornucopia of inventive techniques and methodologies designed to thwart the advances of this pernicious pathogen. Nanochemistry, an artful fusion of chemistry and nanoscience, provides a fertile landscape for researchers to craft innovative shields against infection.

The study aims to explain the discourse of the collective subject of adult and elderly men about the experience of long COVID. Qualitative research, derived from a national multicenter clinical-virtual observatory involving 92 adult men, between 2022 and 2023 in Brazil. IRaMuTeQ software was used (data processing), the Collective Subject Discourse technique (analysis) and socio-anthropological references of the disease experience (interpretation).

At this stage in the COVID-19 pandemic, most infections are "breakthrough" infections that occur in individuals with prior severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) exposure. To refine long-term vaccine strategies against emerging variants, we examined both innate and adaptive immunity in breakthrough infections. We performed single-cell transcriptomic, proteomic, and functional profiling of primary and breakthrough infections to compare immune responses from unvaccinated and vaccinated individuals during the SARS-CoV-2 Delta wave.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and influenza viruses lead to severe respiratory illnesses and death in humans, exacerbated in individuals with underlying health conditions, remaining substantial global public health concerns. Here, we developed a bivalent replication-incompetent single-cycle pseudotyped vesicular stomatitis virus vaccine that incorporates both a prefusion-stabilized SARS-CoV-2 spike protein lacking a furin cleavage site and a full-length influenza A virus neuraminidase protein. Vaccination of K18-hACE2 or C57BL/6J mouse models generated durable levels of neutralizing antibodies, T cell responses, and protection from morbidity and mortality upon challenge with either virus.
