Surgery for an Uncommon Pathology: Pancreatic Metastases from Renal Cell Carcinoma-Indications, Type of Pancreatectomy, and Outcomes in a Single-Center Experience.

: The role of surgery in pancreatic metastases of renal cell carcinoma (PM_RCC) is highly controversial, particularly in the context of modern systemic therapies and the conflicting results of studies published so far. This study aims to explore a single surgical center experience (including mainly pancreatic resections) regarding the indications, the type of pancreatectomies, and early and long-term outcomes for PM_RCC. : The data of all patients with surgery for PM_RCC (from 1 January 2002 to 31 December 2023) were retrospectively assessed, and potential predictors of survival were explored.

Management of a Rare Case of Superior Mesenteric Artery Aneurysm Associated with a Pancreatic Cyst Complicated by Acute Rupture: A Case Report and Review of Literature.

Superior mesenteric artery aneurysms are a rare pathology, and rupture due to a pancreatic cyst in the context of alcohol-induced pancreatitis is an even rarer condition. The first line of treatment is usually an endovascular approach. We present the case of a 51-year-old male with alcohol-induced pancreatitis, diagnosed with a superior mesenteric artery aneurysm with active bleeding in close contact with a large pancreatic cyst.

Effect of Surface Roughness on the Electrochemical Behavior and Corrosion Resistance of TiTaNbZrAg Alloy with Different Amounts of Tantalum in Bulk Composition.

The corrosion behavior of the TiTaNbZrAg alloys with different amounts of tantalum (0%, 10% and 20%) and with distinct surface topography (smooth and rough) was investigated in phosphate buffer solution (PBS) for long-time immersion (1000 h). By this approach, we expect to bring about new insights into the influence of both the amount of Ta in the alloy composition and the surface topography on the corrosion behavior of the Ti-based alloys. The corrosion resistance was studied by Open Circuit Potential (OCP), Potentiodynamic Polarization (PP), and Electrochemical Impedance Spectroscopy (EIS).

The place of splenectomy in the therapeutic management of patients with infective endocarditis and splenic abscess: A single center experience and a literature review.

Introduction: Infective endocarditis(IE) has a low incidence, but it remains a serious disease with high mortality rates. Only 5 % of these patients will develop a splenic abscess, and the number of patients that have IE and a splenic abscess requiring surgery is low. The current guidelines recommend that splenectomy should be performed prior to valve replacement, but there is no strong evidence to support this statement and no evidence to clearly endorse the order in which the surgical interventions should be performed.

The Decline of Open, Laparoscopic, and Robotic Splenectomies: A Single Center Experience.

Splenectomy has been performed for various indications from haematological diseases to benign cysts and tumours, and for splenic traumatic injuries. However, there has been a steady decline in splenectomies in the last 20 years. The aim of this study is to establish the reasons behind this decline in splenectomy and to analyse them based on indication, type of splenectomy, and manner of approach (open, laparoscopic or robotic).

A Glimpse into the Role and Effectiveness of Splenectomy for Isolated Metachronous Spleen Metastasis of Colorectal Cancer Origin: Long-Term Survivals Can Be Achieved.

: Many papers exploring the role of resectioning metastases in colorectal cancer (CRC) have focused mainly on liver and lung sites, showing improved survival compared with non-resectional therapies. However, data about exceptional metastatic sites such as splenic metastases (SMs) are scarce. This paper aims to assess the role and effectiveness of splenectomy in the case of isolated metachronous SM of CRC origin.

Genetic variants affecting NQO1 protein levels impact the efficacy of idebenone treatment in Leber hereditary optic neuropathy.

Idebenone, the only approved treatment for Leber hereditary optic neuropathy (LHON), promotes recovery of visual function in up to 50% of patients, but we can neither predict nor understand the non-responders. Idebenone is reduced by the cytosolic NAD(P)H oxidoreductase I (NQO1) and directly shuttles electrons to respiratory complex III, bypassing complex I affected in LHON. We show here that two polymorphic variants drastically reduce NQO1 protein levels when homozygous or compound heterozygous.

Recessive TMOD1 mutation causes childhood cardiomyopathy.

Familial cardiomyopathy in pediatric stages is a poorly understood presentation of heart disease in children that is attributed to pathogenic mutations. Through exome sequencing, we report a homozygous variant in tropomodulin 1 (TMOD1; c.565C>T, p.

Short-term Outcome of Robotic and Laparoscopic Surgery for Gynecological Malignancies: A Single-center Experience.

Objectives: Minimally invasive surgery (MIS) has become the preferred option for many gynecologic pathologies since complication rate and postoperative recovery time have decreased considerably. Postoperative complications remain an important aspect when using the MIS approach, if they are not timely or accurately diagnosed and treated. The main aim of the study is to first assess their incidence, followed by identifying possible risk factors.

Propensity Score-Matched Analysis of Minimal Invasive Surgery versus Open Surgery for Colorectal Cancer in Older Patients.

Currently, surgeons deal with an older patient cohort, confronting new challenges brought by the raised life expectancy. This population is unrepresented in surgical trials; therefore, the optimal therapy is still a matter of debate. The efficacy of open versus minimal invasive management of colorectal cancer (CRC) in an elderly cohort is not clearly established.

Robotic or laparoscopic pelvic exenteration for gynecological malignancies: feasible options to open surgery.

Objective: To acknowledge that minimally invasive pelvic exenteration is a feasible alternative to open surgery and potentially identify prediction factors for patient outcome.

Methods: The study was designed as a retrospective single team analysis of 12 consecutive cases, set between January 2008 and January 2022.

Results: Six anterior and 6 total pelvic exenterations were performed.

Achalasia Treatment. Robotic Approach or Laparoscopy?

Nowadays the question persists whether to choose the endoscopic or surgical method as the first treatment of choice for achalasia. Another debate topic is about the differences between the outcomes of the two approaches of minimally invasive surgical treatment and their feasibility. Material and This retrospective observational study included 193 patients with achalasia treated between 2008 and 2021.

Quantitative Textual Analysis as a means to explore corporate interests in food safety.

The growing body of scholarship on the commercial determinants of health has, so far, mostly employed qualitative methods but this is now being complemented by a small, yet growing, corpus of quantitative studies. We illustrate the use of one such method, quantitative text analysis (QTA), in a case study of submissions to a public consultation on a draft scientific opinion by the European Food Safety Authority on the chemical acrylamide, demonstrating how this method can be used and insights that might be drawn from it. We use Wordscores as one example of QTA to illuminate the diverse positions taken by actors submitting comments and then assess whether the final policy documents moved towards or away from the positions taken by different stakeholders.

Anti-miR-93-5p therapy prolongs sepsis survival by restoring the peripheral immune response.

Sepsis remains a leading cause of death for humans and currently has no pathogenesis-specific therapy. Hampered progress is partly due to a lack of insight into deep mechanistic processes. In the past decade, deciphering the functions of small noncoding miRNAs in sepsis pathogenesis became a dynamic research topic.

Safety and Efficacy of Simultaneous Resection of Gastric Carcinoma and Synchronous Liver Metastasis-A Western Center Experience.

: Gastric cancer (GC) is often diagnosed in the metastatic stage. Palliative systemic therapy is still considered the gold standard, even for patients with resectable oligometastatic disease. The aim of the current study is to assess the potential benefit of up-front gastric and liver resection in patients with synchronous resectable liver-only metastases from GC (LMGC) in a Western population.

Molecular profile of the NF-κB signalling pathway in human colorectal cancer.

The development and progression of colorectal cancer (CRC) have been associated with inflammation processes that involve the overactivation of the NF-κB signalling pathway. The characterization of the NF-κB expression profile in CRC is an important topic since the suppression of NF-κB represents a potential therapeutic approach. In this study, we assessed the expression levels of 84 NF-κB-related genes in paired tumoral (T) and peritumoral (PT) tissues from 18 CRC patients and 18 normal colonic mucosae, and the expression levels of three miRNAs targeting the most dysregulated genes revealed by the case-control analysis.

Enhancement of the Catalytic Performance and Operational Stability of Sol-Gel-Entrapped Cellulase by Tailoring the Matrix Structure and Properties.

Commercial cellulase Cellic CTec2 was immobilized by the entrapment technique in sol-gel matrices, and sol-gel entrapment with deposition onto magnetic nanoparticles, using binary or ternary systems of silane precursors with alkyl- or aryl-trimethoxysilanes, at different molar ratios. Appropriate tailoring of the sol-gel matrix allowed for the enhancement of the catalytic efficiency of the cellulase biocatalyst, which was then evaluated in the hydrolysis reaction of Avicel microcrystalline cellulose. A correlation between the catalytic activity with the properties of the sol-gel matrix of the nanobiocatalysts was observed using several characterization methods: scanning electron microscopy (SEM), fluorescence microscopy (FM), Fourier transform infrared spectroscopy (FT-IR) and thermogravimetric analysis (TGA/DTA).

The seen and the unseen: Molecular classification and image based-analysis of gastrointestinal cancers.

Gastrointestinal cancers account for 22.5% of cancer related deaths worldwide and represent circa 20% of all cancers. In the last decades, we have witnessed a shift from histology-based to molecular-based classifications using genomic, epigenomic, and transcriptomic data.

Development of a Tailored Sol-Gel Immobilized Biocatalyst for Sustainable Synthesis of the Food Aroma Ester -Amyl Caproate in Continuous Solventless System.

This study reports the synthesis of a hybrid sol-gel material, based on organically modified silanes (ORMOSILs) with epoxy functional groups, and its application in the stabilization of lipase type B from (CalB) through sol-gel entrapment. The key immobilization parameters in the sol-gel entrapment of lipase using epoxysilanes were optimized by the design of numerous experiments, demonstrating that glycidoxypropyl-trimethoxysilane can allow the formation of a matrix with excellent properties in view of the biocatalytic esterifications catalyzed by this lipase, at an enzyme loading of 25 g/mol of silane. The characterization of the immobilized biocatalyst and the correlation of its catalytic efficiency with the morphological and physicochemical properties of the sol-gel matrix was accomplished through scanning electron microscopy (SEM), fluorescence microscopy (FM), as well as thermogravimetric and differential thermal analysis (TGA/DTA).

Endoscopic Retrograde Cholangiopancreatography in Acute Biliary Pancreatitis: Urgent vs. Delayed and the Outcome of Same-Admission Cholecystectomy.

Acute pancreatitis (AP) represents a major burden for the medical system, associating important morbidity and mortality rates. This paper is focused on debatable aspects of the management of biliary AP, namely indications, timing and outcomes of endoscopic retrograde cholangiopancreatography (ERCP) on the hand and, on the other hand, same-admission cholecystectomy as a preventive measure for recurrent disease. Material and methods: This is a retrospective study including 108 patients with biliary AP in whom ERCP was performed, treated in the Clinical Emergency Hospital of Bucharest between 2016 and 2020.

Combined Positive Score for Programmed Death Ligand-1 Expression and Inflammatory Microenvironment in Gastrointestinal Stromal Tumors.

: GISTs are the most frequent type of mesenchymal neoplasm of the digestive tract. The prognosis is mainly determined by tumor dimensions, mitotic rate and location, but other less well-documented factors can influence evolution and survival. The immune microenvironment and checkpoint molecule expression were proven to impact the prognosis in different types of cancer.
