Objective: Splenectomy is regularly performed in total and distal pancreatectomy due to technical reasons, lymph node dissection and radicality of the operation. However, the spleen serves as an important organ for competent immune function, and its removal is associated with an increased incidence of cancer and a worse outcome in some cancer entities (Haematologica 99:392-398, 2014; Dis Colon Rectum 51:213-217, 2008; Dis Esophagus 21:334-339, 2008). The impact of splenectomy in pancreatic cancer is not fully resolved (J Am Coll Surg 188:516-521, 1999; J Surg Oncol 119:784-793, 2019).

Built-in selection or confounder bias? Dynamic Landmarking in matched propensity score analyses.

BMC Med Res Methodol

December 2024

German Diabetes Center, Leibniz Center for Diabetes Research, Institute for Biometrics and Epidemiology, Heinrich-Heine-University Düsseldorf, Düsseldorf, Germany.

Background: Propensity score matching has become a popular method for estimating causal treatment effects in non-randomized studies. However, for time-to-event outcomes, the estimation of hazard ratios based on propensity scores can be challenging if omitted or unobserved covariates are present. Not accounting for such covariates could lead to treatment estimates, differing from the estimate of interest.

Incentive salience theory both explains the directional component of motivation (in terms of cue attraction or "wanting") and its energetic component, as a function of the strength of cue attraction. This theory characterizes cue- and reward-triggered approach behavior. But it does not tell us how behavior can show enhanced vigor under reward uncertainty, when cues are inconsistent or resources hidden.

Background: Immune checkpoint inhibitors (ICIs) are an important therapeutic pillar in metastatic urothelial carcinoma (mUC). The occurrence of immune-related adverse events (irAEs) appears to be associated with improved outcomes in observational studies. However, these associations are likely affected by immortal time bias and do not represent causal effects.

The CoA thioester of 2-(carboxymethyl)cyclohexane-1-carboxylic acid has been identified as a metabolite in anaerobic naphthalene degradation by the sulfate-reducing culture N47. This study identified and characterised two acyl-CoA dehydrogenases (ThnO/ThnT) and an intramolecular CoA-transferase (ThnP) encoded within the substrate-induced thn operon, which contains genes for anaerobic degradation of naphthalene. ThnP is a CoA transferase belonging to the family I (Cat 1 subgroup) that catalyses the intramolecular CoA transfer from the carboxyl group of 2-(carboxymethyl)cyclohexane-1-carboxyl-CoA to its carboxymethyl moiety, forming 2-carboxycyclohexylacetyl-CoA.
