Extracorporeal Membrane Oxygenation Without Mechanical Ventilation for Recovery From Tracheal Repair.

Postoperative positive pressure ventilation (PPV) can contribute to failure of large intrathoracic airway repairs. We report a case of a 67-year-old woman with severe emphysema who presented with an unstable airway and mediastinitis after full-length transmural intrathoracic tracheal intubation injury. After repair, neither extubation nor PPV distal to the repair was feasible.

Comparative pathogenicity of entomopathogenic nematodes symbiotic bacteria- distinct intra- and inter-species variation.

This study aimed to achieve two main objectives: first, to determine whether the virulence factors of symbiotic bacteria of entomopathogenic nematodes (EPNs) against insect hosts are cell-associated or secreted, and to shed light on the underlying mechanisms of pathogenicity; and second, to identify and evaluate the standalone pathogenicity of symbiotic bacteria associated with entomopathogenic nematodes against Tenebrio molitor. Three bacterial species, Xenorhabdus nematophila (A41, SC, A18 and SF), Photorhabdus kayaii, and P. thracensis, were isolated and characterized via phylogenetic analysis of 16S-rRNA and gyrB genes.

COVID-19 vaccines: current and future challenges.

As of December 2020, around 200 vaccine candidates for Coronavirus Disease 2019 (COVID-19) are being developed. COVID-19 vaccines have been created on a number of platforms and are still being developed. Nucleic acid (DNA, RNA) vaccines, viral vector vaccines, inactivated vaccines, protein subunit vaccines, and live attenuated vaccines are among the COVID-19 vaccine modalities.

The relationship between internet addiction and lifestyle among high school students: A cross sectional in the west of Iran.

Excessive internet usage can precipitate internet addiction (IA), negatively impacting lifestyle behaviors, especially during adolescence. These warrants investigating associations between IA and lifestyle factors. To examine the relationship between IA and health-promoting lifestyle dimensions among Iranian high school students.

Pulmonary Embolism Following Lung Transplantation: Prevention and Management.

Thromboembolic events are the third leading cardiovascular diagnosis following stroke and myocardial infarction. In the United States, 300,000 to 600,000 people per year are diagnosed with venous thromboembolism, either deep venous thrombosis or pulmonary embolism (PE). Of those patients, thousands die from PE despite heightened vigilance and improved therapies.
