This study investigated the relative contributions of medial temporal lobe (MTL) integrity and frontal lobe functions in behavioral variant frontotemporal dementia (bvFTD), Alzheimer’s disease (AD), and mild cognitive impairment (MCI). We assessed 300 participants using neuropsychological memory tests—Free and Cued Selective Reminding Test (FCSRT), Brief Visuospatial Memory Test-Revised—and MTL volumetry. Propensity score matching examined which subtests were most influenced by frontal functions. Principal component analysis and ridge regression explored the relationship between MTL volumes and memory tests across groups. Significant differences in memory tests and MTL volumes followed the pattern: controls > MCI > bvFTD > AD. AD showed greater impairment than bvFTD in FCSRT Total ( p = .013), Retention ( p = .016), and Free Recall ( p = .009). Correlations between MTL volumes and memory tests were strongest in MCI ( r = –.58), followed by AD ( r = –.36), controls ( r = –.35), and non-significant in bvFTD ( r = –.21). After propensity score matching, several group differences were no longer significant, including cued tasks, delayed recall, and retention. These findings support a continuum of frontal and MTL contributions to memory deficits. AD is primarily marked by MTL-related impairments, which are less pronounced in bvFTD. MTL volumetry influence on these memory tests in MCI underscores their utility in detecting subtle MTL-dependent memory dysfunction.

Peptic ulcers are not the most common complication in gastrointestinal mucosa, but these defects stand out as being the complication with the highest mortality rate. Several scoring systems based on clinical and biochemical parameters, such as the Boey and PULP scoring system have been developed to predict the probability of mortality. In this study, a data mining process is performed in the medical data available, in order to evaluate how the scoring systems perform when trying to predict mortality and patients' state complication. Furthermore, the presented paper studies the two scoring systems presented to define which one outperforms the other. On one hand PULP scoring allows a better mortality prediction achieving, above a 90% accuracy. One the other hand, regarding complications, the Boey system achieves better results leading to a better prediction when it comes to predicting patients' state complication.
