Background/aims: Although pylorus-preserving gastrectomy (PPG) is performed as a function preserving surgery, patients sometimes suffer from postoperative stasis of the gastric contents after the procedure. Preservation of blood flow and both celiac and pyloric branches of the vagal nerve may decrease the incidence of the stasis.
Methodology: Patients who underwent PPG at the Cancer Institute Hospital between April 2005 and December 2007 were included in the study. Early surgical results and the incidence of stasis were investigated and compared between patients in whom the celiac branch had been preserved (PPG-CBP group) and those in whom it had not (PPG-nCBP group).
Results: Patients in the PPG-nCBP group had a higher body mass index than patients in the PPG-CBP group (23.9 vs. 22.3 kg/m2; p=0.004), as well as a longer operation time (249.3 vs. 227.0 min; p=0.010). There was no significant difference in the incidence of stasis between the groups (13% vs. 8%; p=0.523).
Conclusions: There was no correlation between preservation of the celiac branch and the incidence of stasis in the first 30 days after PPG. A large randomized control trial investigating both short- and long-term outcomes after PPG is required to elucidate the primary cause of postoperative stasis.

T-branch by partial deployment technique in the endovascular repair of complex aortic and thoracoabdominal aneurysms with narrow or severe angulated para-visceral aorta.
J Vasc Surg
January 2025
Vascular Surgery, University of Bologna, DIMEC, Bologna, Italy; Vascular Surgery Unit, IRCCS Sant'Orsola, Bologna, Italy.
Introduction/aim: The partial deployment technique (PDT) is an unconventional option of T-branch deployment to allow target arteries (TAs) cannulation/stenting from the upper arm access, in case of narrow (NPA: <25mm) or severely angulated (APA: >60°) aorta. Aim of this study was to report outcomes of the endovascular repair of complex aortic (c-AAAs) and thoracoabdominal (TAAAs) aneurysms by T-branch and PDT.
Methods: All consecutive patients underwent urgent endovascular repair of c-AAAs and TAAAs by T-branch (Cook-Medical, Bloomington, IN, US) and PDT from 2021 to 2023 were analyzed.
Fortuitous discovery of a superior and posterior pancreaticoduodenal artery originating from the right branch of the hepatic artery during cadaver dissection.

Introduction: The duodeno-pancreatic region is a highly vascularized area. The superior and posterior pancreaticoduodenal artery is a vessel primarily originating from the gastroduodenal artery. It exhibits rare anatomical variations, such as its emergence from the right branch of the hepatic artery, which we fortuitously identified during a cadaver dissection.

Article Synopsis
- Prolamins found in wheat, barley, and rye are linked to health issues like celiac disease and wheat allergies, pushing the need for gluten-free alternatives like rice flour, though its products are not as high-tech.
- Adding low-fat desiccated coconut flour and xanthan gum to rice flour significantly improves the quality and properties of gluten-free cakes, impacting viscosity, moisture, and texture.
- The study successfully optimized a gluten-free cake recipe, achieving improved sensory qualities (taste, texture, etc.) through careful ratios of rice flour, coconut flour, and xanthan gum, validated by strong statistical models.
Outcome of Single Versus Dual Antiplatelet Therapy After Complex Endovascular Aortic Repair.

Clinic for Vascular and Endovascular Surgery, Medical Faculty and University Hospital Düsseldorf, Heinrich-Heine-University, Düsseldorf, Germany. Electronic address:
Introduction: Despite the widespread use of branched (bEVAR) and fenestrated endovascular aortic repair (fEVAR) for complex aortic pathologies, there are no reliable recommendations regarding postsurgery antiplatelet therapy. We therefore evaluated the outcome of single (SAPT) and dual antiplatelet therapy (DAPT) following fEVAR and bEVAR.
Methods: A total of 63 patients from two German centers treated for complex aortic pathologies were included in this retrospective study.
A common form of dominant human IFNAR1 deficiency impairs IFN-α and -ω but not IFN-β-dependent immunity.
J Exp Med

Autosomal recessive deficiency of the IFNAR1 or IFNAR2 chain of the human type I IFN receptor abolishes cellular responses to IFN-α, -β, and -ω, underlies severe viral diseases, and is globally very rare, except for IFNAR1 and IFNAR2 deficiency in Western Polynesia and the Arctic, respectively. We report 11 human IFNAR1 alleles, the products of which impair but do not abolish responses to IFN-α and -ω without affecting responses to IFN-β. Ten of these alleles are rare in all populations studied, but the remaining allele (P335del) is common in Southern China (minor allele frequency ≈2%).
