Somatic A-to-I RNA-edited RHOA isoform 2 specific-R176G mutation promotes tumor progression in lung adenocarcinoma.

Adenosine-to-inosine (A-to-I) RNA editing is the most common posttranscriptional editing to create somatic mutations and increase proteomic diversity. However, the functions of the edited mutations are largely underexplored. To identify novel targets in lung adenocarcinoma (LUAD), we conducted a genome-wide somatic A-to-I RNA editing analysis of 23 paired adjacent normal and LUAD transcriptomes and identified 26,280 events, including known nonsynonymous AZIN1-S367G and novel RHOAiso2 (RHOA isoform 2)-R176G, tubulin gamma complex associated protein 2 (TUBGCP2)-N211S, and RBMXL1-I40 M mutations.

PrtA immunization fails to protect against pulmonary and invasive infection by Streptococcus pneumoniae.

Background: Streptococcus pneumoniae is a respiratory pathogen causing severe lung infection that may lead to complications such as bacteremia. Current polysaccharide vaccines have limited serotype coverage and therefore cannot provide maximal and long-term protection. Global efforts are being made to develop a conserved protein vaccine candidate.

Modified single-port non-intubated video-assisted thoracoscopic decortication in high-risk parapneumonic empyema patients.

Background: Parapneumonic empyema patients with coronary artery disease and reduced left ventricular ejection fraction are risky to receive surgical decortication under general anesthesia. Non-intubated video-assisted thoracoscopy surgery is successfully performed to avoid complications of general anesthesia. We performed single-port non-intubated video-assisted flexible thoracoscopy surgery in an endoscopic center.

Video-assisted thoracoscopic surgery for recurrent pneumothorax in pulmonary lymphangioleimyomatosis with tuberous sclerosis complex.

Pneumothorax in pulmonary lymphangioleiomyomatosis (LAM) with tuberous sclerosis complex (TSC) is a difficult condition to manage. Video-assisted thoracoscopic surgery (VATS) may play a role in diagnosis and treatment of this situation. We present a case of right recurrent pneumothorax due to LAM with TSC in whom VATS was performed for pathological diagnosis and mechanical pleurodesis.

Late gastric incarceration 20 years after penetrating chest trauma.

The diagnosis of diaphragmatic injury in trauma patients is a challenge for surgeons. Misdiagnosis is common and can only be corrected when patients present with symptoms of diaphragmatic hernia. We report a rare case of delayed traumatic diaphragmatic hernia masquerading as empyema 20 years after lower chest penetrating trauma.
