The novel SARS-CoV-2 introduced several new inflammatory conditions including SARS-CoV-2-associated rhabdomyolysis and viral myositis. We present a 22-year-old man who noted a week of cough followed by myalgias, dark-colored urine, and decreased oral intake. He was found to have acute nontraumatic rhabdomyolysis after an acutely positive SARS-CoV-2 test. Initial creatine kinase (CK) level was above the reference range as were liver enzymes reflective of muscle breakdown. Treatment involved fluid resuscitation and pain control, with close monitoring of kidney, liver, and skeletal markers over five days of hospitalization till there was clinical and symptomatic improvement.

UNASSIGNED: Antibiotics frequently induce abnormal liver function. Omadacycline is a novel aminomethylcycline antibiotic, which shows potent activity against Gram-positive and Gram-negative aerobic, anaerobic, and atypical (including Legionella pneumophila) bacteria. Of note, omadacycline is tolerable in most patients with liver impairment. However, evidence regarding the application of omadacycline in patients with Legionella pneumophila pneumonia after experiencing liver dysfunction is scarce.
UNASSIGNED: The current study reported 6 cases of patients with Legionella pneumophila pneumonia receiving omadacycline as subsequent antibiotics after experiencing liver dysfunction.
UNASSIGNED: These 6 cases were admitted to the hospital for pneumonia and received antibiotic therapy, including piperacillin-tazobactam, imipenem, meropenem, and moxifloxacin. After receiving these antibiotics, increased liver enzymes were noted. Although hepatoprotective therapy (such as magnesium isoglycyrrhizinate and glutathione) was given, the liver function was still abnormal. According to metagenomic next-generation sequencing, these patients were diagnosed with Legionella pneumophila pneumonia. Considering the abnormal liver function, the antibiotic therapy was switched to omadacycline-containing antibiotic therapy. After that, liver function was improved, and the infection was ameliorated. Ultimately, all patients discharged from the hospital, including 2 patients who achieved complete clinical symptomatic improvement and 4 patients who achieved partial clinical symptomatic improvement.
UNASSIGNED: This study emphasizes the successful treatment of switching to omadacycline after experiencing abnormal liver function in patients with Legionella pneumophila pneumonia. This study suggests that omadacycline may serve as an optional antibiotic for patients with Legionella pneumophila pneumonia, especially when occurring liver dysfunction. However, more clinical studies are required to validate our findings.

As the pediatric patient with right pulmonary artery agenesis (PAA) matured, she progressively presented symptoms of pulmonary hypertension and hemoptysis. There is limited clinical literature on this condition, and currently, there is no consensus regarding its diagnosis and treatment. This article presents a case study of a 16-year-old female patient with right pulmonary artery hypoplasia, providing a comprehensive summary and analysis of her developmental progression, pathology, diagnosis, and treatment.

This report describes a male in his late 20s who presented with a 2-month history of recurrent haemoptysis and chest pain. A chronic infection, such as tuberculosis, was suspected. He had undergone surgical resection of an intrapericardial hydatid cyst in the past. His blood investigations showed peripheral eosinophilia, and his chest X-ray showed a cystic oval lesion in the left upper zone. A CT pulmonary angiogram revealed filling defects in the bilateral segmental and subsegmental arteries with a cystic lesion in the left upper lobe. Further workup, including bronchoalveolar lavage culture and MRI of the thorax, confirmed the diagnosis of a hydatid cyst of pulmonary echinococcosis. This case illustrates the presentation of multisystemic echinococcosis in a young male with no other risk factors, initially treated with surgical resection and antihelminthic therapy. The disease later recurred, which required prolonged medications, which brought the patient into remission.

Convalescent plasma was proposed for passive immunization against COVID-19; but so far there are conflicting results and still open questions. However, besides antibodies, other plasma proteins may be good candidates for further research and application. Thromboinflammation frequently complicates severe COVID-19, and classical anticoagulants like heparins seem to have limited effect. The natural protease inhibitors antithrombin III (ATIII), α1-antitrypsin (α1-AT) and α2-macroglobulin (α2-M), which are found decreased in severe COVD-19, play a crucial role in prothrombotic and inflammatory pathways. While ATIII and α1-AT are licensed as commercially prepared therapeutic concentrates, there is no preparation of α2-M available. The diagnostic, prognostic, and even therapeutic potential of plasma protease inhibitors should be further explored.

The recent rise in artificial intelligence systems, such as ChatGPT, poses a fundamental problem for the educational sector. In universities and schools, many forms of assessment, such as coursework, are completed without invigilation. Therefore, students could hand in work as their own which is in fact completed by AI. Since the COVID pandemic, the sector has additionally accelerated its reliance on unsupervised \'take home exams\'. If students cheat using AI and this is undetected, the integrity of the way in which students are assessed is threatened. We report a rigorous, blind study in which we injected 100% AI written submissions into the examinations system in five undergraduate modules, across all years of study, for a BSc degree in Psychology at a reputable UK university. We found that 94% of our AI submissions were undetected. The grades awarded to our AI submissions were on average half a grade boundary higher than that achieved by real students. Across modules there was an 83.4% chance that the AI submissions on a module would outperform a random selection of the same number of real student submissions.

UNASSIGNED: Chlamydia abortus pneumonia is very rare in normal people. At present, there is a lack of clinical data on the clinical characteristics and diagnosis and treatment experience of patients with this type of infection. Our team had recently treated 7 cases of these patients. This study aims to comprehensively summarize and analyze the clinical characteristics and treatment methods of Chlamydia abortus pneumonia, and to provide clinical evidence for the diagnosis and treatment of Chlamydia abortus pneumonia.
UNASSIGNED: Clinical data were retrospectively collected from patients diagnosed with Chlamydia abortus pneumonia through metagenomic next-generation sequencing (mNGS) at the Department of Pulmonary and Critical Care Medicine, Meizhou People\'s Hospital.
UNASSIGNED: Seven patients with Chlamydia abortus pneumonia reported a history of poultry exposure, experiencing fever alongside respiratory or digestive symptoms. Marked elevation of blood inflammation markers, accompanied by hypoproteinemia and liver damage, was observed. Chest CT scans revealed pneumonia and pleural effusion. Chlamydia abortus was detected in blood or bronchoalveolar lavage fluid (BALF) through mNGS, often co-occurring with Chlamydia psittaci or other bacteria infections. Notably, Doxycycline demonstrated efficacy in treating Chlamydia abortus.
UNASSIGNED: Chlamydia abortus infection is a zoonotic disease, particularly among individuals with a history of poultry exposure, and mNGS emerges as a reliable diagnostic tool for its detection. Chlamydia abortus infection manifests with systemic and lung inflammation, effectively addressed through Doxycycline therapy.

Mediastinal tumors are exceedingly rare during fetal development, presenting significant diagnostic challenges and potentially leading to severe outcomes such as stillbirth or metastatic disease if not promptly identified and managed. Pleuropulmonary blastomas are primitive mesenchymal tumors often linked to mutations in the DICER1 gene, indicating a hereditary pattern associated with other common adult neoplasms with dominant inheritance. This report describes a case involving a 20-year-old Caucasian woman whose pregnancy was complicated by a stillbirth in the second trimester. Initial suspicions of a mediastinal tumor arose from blood tests and ultrasound examinations during pregnancy surveillance. However, the definitive diagnosis of a type II pleuropulmonary blastoma was established through a pathological examination at autopsy. This case underscores the complexities of diagnosing fetal mediastinal tumors and contributes to the sparse literature on neonatal pleuropulmonary blastomas. Our comprehensive review of the differential diagnoses and literature emphasizes the unique characteristics of pleuropulmonary blastoma and its similarities to other soft tissue sarcomas, enhancing understanding of their clinical and genetic profiles.

Granulocyte colony-stimulating factor (G-CSF)-producing lung tumours are rare, with their imaging features and effective treatments remaining elusive. Similarly, mesenchymal-epithelial transition (MET) exon 14 skipping mutations are also uncommon. Herein, we report a case of G-CSF-producing lung adenocarcinoma positive for a MET exon 14 skipping mutation, mimicking lung abscess. A 61-year-old man presented with cough and high fever. Contrast-enhanced chest computed tomography revealed a mass with a cavity and internal fluid accumulation. The patient initially underwent diagnostic treatment for a lung abscess but was ultimately diagnosed with lung adenocarcinoma positive for a MET exon 14 skipping mutation. Following tepotinib therapy, the primary lesion shrank, and serum G-CSF levels decreased, leading to a diagnosis of G-CSF-producing lung cancer. G-CSF-producing lung tumours can present imaging findings that mimic lung abscesses. Tepotinib therapy may be effective for patients with MET exon 14 skipping mutation, including those with G-CSF-producing lung cancer.

A popliteal venous aneurysm (PVA) is a rare vascular disorder. We report a case of PVA discovered through further evaluation of sudden cardiac arrest (CA) caused by a pulmonary embolism (PE). It is well-known that PVA causes PE; however, there are few reports of PVA causing CA. A tangential aneurysmectomy and lateral venorrhaphy were performed. The patient\'s postoperative course was uneventful. When contrast-enhanced computed tomography is performed to search for the cause of CA, PVA should be considered and thus, screening below the knee is recommended. At 1-year follow-up, there were no complications.
