Background: Extended gastrectomy allows a complete tumor excision in patients with advanced gastric cancer.
Aim: To compare the surgical results of extended (ER) and non-extended gastrectomy (NER) among patients with gastric cancer, and determine factors associated with complications and mortality.
Material And Methods: Review of medical records of patients with gastric cancer who underwent complete resection between 2002 and 2008 in an oncological hospital. Demographics, patient-related and therapeutic features were compared between groups, and independent factors were established with multivariate analysis.
Results: Seventy four patients, (44 men, median age 62 years) underwent an ER and 103 patients, (56 men, median age 61 years) a NER. Specifically, ER included splenectomy alone in 27 patients, splenectomy associated with other procedure in 24, partial esophagectomy in 18, distal pancreatectomy in 13, hemicolectomy in 8, total esophagectomy in 7, partial hepatectomy in 4, and adrenalectomy in 1. Postoperative complications were observed in 19 patients treated with an ER (26%) and in 11 patients treated with a NER (11%), p < 0.05. Serious complications were higher in patients who underwent an ER compared with NER (6 patients (8%) vs. 4 (4%), respectively) p < 0.05. In the same way, mortality was higher in patients treated with ER when it was compared with NER (4 patients (5%) vs two (2%), respectively), p < 0.05. ER and serum albumin levels were independent factors associated to a higher risk of mortality and rate of complications.
Conclusions: ER was associated with a higher rate of general and severe complications, and mortality.

Are patients with Parkinson's disease impaired in the recognition of emotion's authenticity?
J Neuropsychol

In recognising emotions expressed by others, one can make use of both embodied cognition and mechanisms that do not necessarily require activation of the limbic system, such as evoking from memory the meaning of morphological features of the observed face. Instead, we believe that the recognition of the authenticity of an emotional expression is primarily based on embodied cognition, for which the mirror system would play a significant role. To verify this hypothesis, we submitted 20 parkinsonian patients and 20 healthy control subjects to the Emotional Authenticity Recognition test, a novel test using dynamic stimuli to evaluate the ability to recognise emotions and their authenticity.

Specific determinants associated with Uropathogenic (UPEC) causing recurrent cystitis are still poorly characterized. Using strains from a previous clinical study (Vitale study, clinicaltrials.gov, identifier NCT02292160) the aims of this study were (i) to describe genomic and phenotypic traits associated with recurrence using a large collection of recurrent and paired sporadic UPEC isolates and (ii) to explore within-host genomic adaptation associated with recurrence using series of 2 to 5 sequential UPEC isolates.

While tumor organoids have revolutionized cancer research by recapitulating the cellular architecture and behaviors of real tumors in vitro, their lack of functional vasculature hinders their attainment of full physiological capabilities. Current efforts to vascularize organoids are struggling to achieve well-defined vascular networks, mimicking the intricate hierarchy observed in vivo, which restricts the physiological relevance particularly for studying tumor progression and response to therapies targeting the tumor vasculature. An innovative vascularized patient-derived tumor organoids (PDTOs)-on-a-chip with hierarchical, tumor-specific microvasculature is presented, providing a versatile platform to explore tumor-vascular dynamics and antivascular drug efficacy.

Diagnostic wandering and delayed management are major issues in rare diseases. Here, we report a new Next-Generation Phenotyping (NGP) model for diagnosing Coffin Siris syndrome (CSS) on clinical photographs among controls and distinguish the different genotypes. This retrospective and prospective study, conducted from 1998 to 2023, included frontal and lateral pictures of confirmed CSS.

Abutment contours, position, tissue thickness, and volume are all key parameters for the successful restoration of implants in the aesthetic zone. This is particularly true for patients with high smile lines and high aesthetic expectations. This narrative review will provide a synopsis of the known science of implant abutments and peri-implant tissues in this area and cover specialised techniques, materials, and protocols to improve outcomes with increased predictability.
