Surgery for chronic pyothorax after failed amplatzer closure of bronchopleural fistula.

Background: Post-pneumonectomy bronchopleural fistula (BPF) is a life-threatening event whose treatment is not standardized.

Case Presentation: We report the management of a 28-year-old patient with a 3-year history of BPF complicating right pneumonectomy for congenital emphysema. Despite closure by an Amplatzer device, the patient had chronic pyothorax and severely deteriorated general health and quality of life.

In situ detection of individual classical MHC-I gene products in cancer.

Tumor-specific HLA class I expression is required for cytotoxic T-cell elimination of cancer cells expressing tumor-associated or neo-antigens. Cancers downregulate antigen presentation to avoid adaptive immunity. The highly polymorphic nature of the genes encoding these proteins, coupled with quaternary-structure changes after formalin fixation, complicate detection by immunohistochemistry.

Long-term mortality of Dutch COVID-19 patients admitted to the intensive care medicine: a retrospective analysis from a national quality registry.

Objective: To describe the 12-month mortality of Dutch COVID-19 intensive care unit patients, the total COVID-19 population and various subgroups on the basis of the number of comorbidities, age, sex, mechanical ventilation, and vasoactive medication use.

Methods: We included all patients admitted with COVID-19 between March 1, 2020, and March 29, 2022, from the Dutch National Intensive Care (NICE) database. The crude 12-month mortality rate is presented via Kaplan-Meier survival curves for each patient subgroup.

Solution biophysics identifies lipid nanoparticle non-sphericity, polydispersity, and dependence on internal ordering for efficacious mRNA delivery.

Lipid nanoparticles (LNPs) are the most advanced delivery system currently available for RNA therapeutics. Their development has accelerated since the success of Patisiran, the first siRNA-LNP therapeutic, and the mRNA vaccines that emerged during the COVID-19 pandemic. Designing LNPs with specific targeting, high potency, and minimal side effects is crucial for their successful clinical use.

Approaches for extracting daily dosage from free-text prescription signatures in heart failure with reduced ejection fraction: a comparative study.

Objective: To compare various methods for extracting daily dosage information from prescription signatures (sigs) and identify the best performers.

Materials And Methods: In this study, 5 daily dosage extraction methods were identified. Parsigs, RxSig, Sig2db, a large language model (LLM), and a bidirectional long short-term memory (BiLSTM) model were selected.
