Abstract Constrictive pericarditis is a rare disease. Localized constrictive pericarditis leading to bilateral pleural effusion is more difficult to recognize, and the diagnostic procedure can be ambiguous. Here, we report two patients diagnosed with localized constrictive pericarditis who presented with bilateral pleural effusion. A thorough work‐up showed that the pleural effusion was nonspecific, as was the pathology of the pleura. One patient had a history of pericardial effusion 2 years ago, and the other had undergone surgery for an anterior mediastinum teratoma. Pericardial scarring was found on their chest CT scans. The patients underwent pericardiectomy, and localized pericardial thickening was excised. The bilateral pleural effusion was effectively cured, and the patients showed satisfactory recovery on follow‐up. Physicians should be aware of localized pericarditis leading to bilateral pleural effusion, and pericardiectomy is an effective diagnostic and therapeutic procedure.

Transgenic modification of silkworms has the potential to engineer new silks with a wider range of properties. Here, the authors engineered the expression of the outer layer sericin SER3 in the inner fibroin layer generating a new silk with higher production efficiency and resistance to alkaline conditions.

AimTo uncover the effect of GLP-1 receptor agonists (GLP-1 RAs) on the visceral- and hepatic fat content of adults.MethodsPubMed, EMBASE, Cochrane Library, and Web of Science were searched from inception until November 2022. Randomized controlled trials (RCTs) of GLP-1Ras was extracted, including reports of effects on visceral adipose tissue and hepatic fat content in individuals with type 2 diabetes, non-type 2 diabetes, NAFLD (non-alcoholic fatty liver disease), and non-NAFLD. Meta-analyses used random-effects models.Results1736 individuals in the 30 qualified RCTs were included, comprising 1363 people with type 2 diabetes and 318 with NFLD. GLP-1 RAs reduced visceral adipose tissue (standard mean difference [SMD] = -0.59, 95% CI [-0.83, -0.36], PConclusionsLP-1 RAs significantly reduce visceral- and liver fat content in adults.
