Nasopharyngeal cancer (NPC) is a rare cancer type with a low five-year survival rate. Dysregulation of PYCR1 and miR-150-5p has been involved in the development of various cancers. However, the molecular mechanism of the miR-150-5p-PYCR1 axis in NPC remains unclear. ⋯ We clarified that miR-150-5p attenuated NPC tumorigenesis through reducing PYCR1 expression. This provides a new perspective of NPC involving both miR-150-5p and PYCR1 for the treatment of NPC.

Pneumothorax and Pneumomediastinum in COVID-19: A Case Series.
COVID- 19 has become a major pandemic affecting more than 11 million people worldwide. Common radiological manifestations of COVID-19 include peripheral based ground-glass or consolidative opacities; however, pneumothorax and pneumo-mediastinum are very rare manifestations; even more so within patients not on mechanical ventilation. We present a case series of 5 patients with COVID-19 who either presented with or developed spontaneous pneumothorax or pneumo-mediastinum within the course of hospitalization. ⋯ Spontaneous pneumothorax or pneumo-mediastinum may be an important late manifestation in COVID-19; even in spontaneously breathing patients. This may be related to development of cystic changes within the lung parenchyma. Although the clinical relevance of this finding is unknown; in our series, it portended a worse prognosis in the majority of patients.

The differential diagnosis of tuberculous pleural effusion (TPE) and parapneumonic pleural effusion (PPE) is challenging due to similar clinical manifestations and body fluid biochemical profiles. Thyroid hormone levels change in response to lymphocyte proliferation in the peripheral blood of patients with mycobacterial infections such as tuberculosis; therefore, this study aimed to investigate the utility of assessing thyroid hormone levels to aid in the differential diagnosis of TPE and PPE. ⋯ Increased FT3 and FT4 levels could potentially be used for the differential diagnosis of TPE and PPE.

Cervical cancer (CC) is the fourth most common gynecological malignancy globally. This suggests the need for improved markers for prognosis, better understanding of the molecular mechanism, and targets for therapy. The defective exocytosis pathway is proposed as bona fide drivers of carcinogenesis. This study aimed to identify the exocytosis pathway network and its contribution to CC. ⋯ In summary, we have identified the exocytosis pathway networks, candidate genes, and novel drugs for better management of CC.

The outcomes of patients with sudden cardiac arrest (SCA) and chronic obstructive pulmonary disease (COPD) are largely unknown. The purpose of this study was to assess mortality, trends, predictors, and outcomes in patients of SCA and COPD from a large inpatient administrative database. ⋯ SCA in settings of COPD may have high mortality when compared to patients with SCA and no concomitant COPD. Further research delving into potential mechanisms for SCA in COPD patients is warranted.
