Feasibility and safety of hyperthermic intra-peritoneal chemotherapy in patients with ovarian cancer and chronic kidney disease.

Objective: This study aimed to compare perioperative outcomes and progression-free and overall survival in patients with chronic kidney disease (CKD) versus those without after hyperthermic intra-peritoneal chemotherapy (HIPEC) for ovarian cancer.

Methods: This is a retrospective, single-institution cohort study of patients with ovarian cancer treated with HIPEC at the Cleveland Clinic from January 2009 to December 2022. All patients received HIPEC with cisplatin and renal protection with mannitol and furosemide.

Patterns of Isoform Variation for N Gene Subgenomic mRNAs in Betacoronavirus Transcriptomes.

The nucleocapsid (N) protein is the most expressed protein in later stages of SARS-CoV-2 infection with several important functions. It is translated from a subgenomic mRNA (sgmRNA) formed by template switching during transcription. A recently described translation initiation site (TIS) with a CTG codon in the leader sequence (TIS-L) is out of frame with most structural and accessory genes including the N gene and may act as a translation suppressor.

Phylogenetic signal in primate tooth enamel proteins and its relevance for paleoproteomics.

Ancient tooth enamel, and to some extent dentin and bone, contain characteristic peptides that persist for long periods of time. In particular, peptides from the enamel proteome (enamelome) have been used to reconstruct the phylogenetic relationships of fossil taxa. However, the enamelome is based on only about 10 genes, whose protein products undergo fragmentation in vivo and post mortem.

Smooth Muscle Myosin Heavy Chain Expression in Nodal and Extranodal Follicular Dendritic Cell Sarcoma.

Follicular dendritic cell sarcoma (FDCS) is a rare neoplasm requiring a high index of suspicion, especially on small biopsies. Smooth muscle myosin heavy chain (SMMHC) is a common immunohistochemical (IHC) stain that has been reported to mark normal nodal follicular dendritic cells (FDCs). We hypothesize that SMMHC can be a sensitive marker for FDCS and aim to compare its performance with established markers of FDCS.

Cost-Benefit Analysis of Various Management Algorithms for Suspected Choledocholithiasis.

The goal of our study is to evaluate the safest, efficient, and most cost-effective way to manage suspected choledocholithiasis. This retrospective study evaluated adult patients with suspected choledocholithiasis based on labs and imaging at a single institution between 2017 and 2022 and characterized them into 1 of 3 groups based on their management pathway: (1) ERCP-first, (2) MRCP-first, or (3) surgery-first with possible intraoperative cholangiogram pending laboratory trend. Our primary outcome was hospital length of stay.
