Acrylamide in alternative snacks to potato: A review.

The snack food market has been changing to keep up with the growing demand for healthier products and, as a result, alternative products to traditional potato chips have been emerging to provide health-related benefits. Extrusion, frying, and baking are the main techniques used worldwide in the processing of snacks and are among the main reasons for the formation of toxic compounds induced by heat, such as acrylamide. This contaminant is formed during thermal processing in foods heated at high temperatures and rich in carbohydrates.

Diagnostic Performance of MRI and FDG PET/CT for Preoperative Locoregional Staging of Colon Cancer: Systematic Review and Meta-Analysis.

CT is the standard-of-care test for preoperative locoregional staging of colon cancer (CC) but has limited diagnostic performance. More accurate preoperative staging would guide selection among expanding patient-tailored treatment options. The purpose of this study was to evaluate through systematic review the diagnostic performance of MRI for T and N staging and that of FDG PET/CT for N staging in the locoregional staging of CC.

Thermal Contaminants in Coffee Induced by Roasting: A Review.

Roasting is responsible for imparting the main characteristics to coffee, but the high temperatures used in the process can lead to the formation of several potentially toxic substances. Among them, polycyclic aromatic hydrocarbons, acrylamide, furan and its derivative compounds, α-dicarbonyls and advanced glycation end products, 4-methylimidazole, and chloropropanols stand out. The objective of this review is to present a current and comprehensive overview of the chemical contaminants formed during coffee roasting, including a discussion of mitigation strategies reported in the literature to decrease the concentration of these toxicants.

Patient selection for urgent endoscopic retrograde cholangio-pancreatography by endoscopic ultrasound in predicted severe acute biliary pancreatitis (APEC-2): a multicentre prospective study.

Objective: Routine urgent endoscopic retrograde cholangiopancreatography (ERCP) with endoscopic biliary sphincterotomy (ES) does not improve outcome in patients with predicted severe acute biliary pancreatitis. Improved patient selection for ERCP by means of endoscopic ultrasonography (EUS) for stone/sludge detection may challenge these findings.

Design: A multicentre, prospective cohort study included patients with predicted severe acute biliary pancreatitis without cholangitis.

The mechanism of macroautophagy: The movie.

This animated movie presents the mechanism of macroautophagy, hereafter autophagy, by showing the molecular features of the formation of autophagosomes, the hallmark organelle of this intracellular catabolic pathway. It is based on our current knowledge and it also illustrates how autophagosomes can recognize and eliminate selected cargoes.

Aggressive fluid hydration plus non-steroidal anti-inflammatory drugs versus non-steroidal anti-inflammatory drugs alone for post-endoscopic retrograde cholangiopancreatography pancreatitis (FLUYT): a multicentre, open-label, randomised, controlled trial.

Background: Pancreatitis is the most common complication of endoscopic retrograde cholangiopancreatography (ERCP). Prophylactic rectal administration of non-steroidal anti-inflammatory drugs (NSAIDs) is considered as standard of care to reduce the risk of post-ERCP pancreatitis. It has been suggested that aggressive hydration might further reduce this risk.

Surface charge modulation of rifampicin-loaded PLA nanoparticles to improve antibiotic delivery in Staphylococcus aureus biofilms.

Background: After the golden age of antibiotic discovery, bacterial infections still represent a major challenge for public health worldwide. The biofilm mode of growth is mostly responsible for chronic infections that current therapeutics fail to cure and it is well-established that novel strategies must be investigated. Particulate drug delivery systems are considered as a promising strategy to face issues related to antibiotic treatments in a biofilm context.

Molecular Dynamics Studies of Poly(Lactic Acid) Nanoparticles and Their Interactions with Vitamin E and TLR Agonists PamCSK and PamCSK.

Poly(lactic acid) (PLA) nanoparticles (NPs) are widely investigated due to their bioresorbable, biocompatible and low immunogen properties. Interestingly, many recent studies show that they can be efficiently used as drug delivery systems or as adjuvants to enhance vaccine efficacy. Our work focuses on the molecular mechanisms involved during the nanoprecipitation of PLA NPs from concentrated solutions of lactic acid polymeric chains, and their specific interactions with biologically relevant molecules.

Fluid hydration to prevent post-ERCP pancreatitis in average- to high-risk patients receiving prophylactic rectal NSAIDs (FLUYT trial): study protocol for a randomized controlled trial.

Background: Post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) is the most common complication of ERCP and may run a severe course. Evidence suggests that vigorous periprocedural hydration can prevent PEP, but studies to date have significant methodological drawbacks. Importantly, evidence for its added value in patients already receiving prophylactic rectal non-steroidal anti-inflammatory drugs (NSAIDs) is lacking and the cost-effectiveness of the approach has not been investigated.

Colicky pain and related complications after cholecystectomy for mild gallstone pancreatitis.

Background: Same-admission cholecystectomy is advised after gallstone pancreatitis to prevent recurrent pancreatitis, colicky pain and other complications, but data on the incidence of symptoms and complications after cholecystectomy are lacking.

Methods: This was a prospective cohort study during the previously published randomized controlled PONCHO trial on timing of cholecystectomy after mild gallstone pancreatitis. Data on healthcare consumption and questionnaires focusing on colicky pain and biliary complications were obtained during 6 months after cholecystectomy.

USP7 inhibition alters homologous recombination repair and targets CLL cells independently of ATM/p53 functional status.

The role of deubiquitylase ubiquitin-specific protease 7 (USP7) in the regulation of the p53-dependent DNA damage response (DDR) pathway is well established. Whereas previous studies have mostly focused on the mechanisms underlying how USP7 directly controls p53 stability, we recently showed that USP7 modulates the stability of the DNA damage responsive E3 ubiquitin ligase RAD18. This suggests that targeting USP7 may have therapeutic potential even in tumors with defective p53 or ibrutinib resistance.

Same-admission versus interval cholecystectomy for mild gallstone pancreatitis (PONCHO): a multicentre randomised controlled trial.

Background: In patients with mild gallstone pancreatitis, cholecystectomy during the same hospital admission might reduce the risk of recurrent gallstone-related complications, compared with the more commonly used strategy of interval cholecystectomy. However, evidence to support same-admission cholecystectomy is poor, and concerns exist about an increased risk of cholecystectomy-related complications with this approach. In this study, we aimed to compare same-admission and interval cholecystectomy, with the hypothesis that same-admission cholecystectomy would reduce the risk of recurrent gallstone-related complications without increasing the difficulty of surgery.

Which Lymph Nodes Contain Metastases in Colon Cancer Patients? A Retrospective Histopathological Evaluation of 156 Patients.

Background: We hypothesized that a reliable N0 status can be established by sampling and evaluating the largest lymph nodes in the resected large-bowel specimen of patients with colon cancer.

Patients And Methods: This was a retrospective analysis of all surgical colon cancer patients treated between 2008 and 2010, excluding those who had received neoadjuvant treatment. We analyzed the relationship between lymph node size and the presence of metastasis.

Lymph Node Yield in Colon Cancer: Individuals Can Make the Difference.

Aim: To investigate the influence of individual surgeons and pathologists on examining an adequate (i.e. ≥10) number of lymph nodes in colon cancer resection specimens.

PFI-1, a highly selective protein interaction inhibitor, targeting BET Bromodomains.

Bromo and extra terminal (BET) proteins (BRD2, BRD3, BRD4, and BRDT) are transcriptional regulators required for efficient expression of several growth promoting and antiapoptotic genes as well as for cell-cycle progression. BET proteins are recruited on transcriptionally active chromatin via their two N-terminal bromodomains (BRD), a protein interaction module that specifically recognizes acetylated lysine residues in histones H3 and H4. Inhibition of the BET-histone interaction results in transcriptional downregulation of a number of oncogenes, providing a novel pharmacologic strategy for the treatment of cancer.

Laparoscopic partial cholecystectomy for the difficult gallbladder: a systematic review.

Background: In the setting of difficult dissection of Calot's triangle during laparoscopic cholecystectomy, conversion is commonly advocated. An alternative approach aimed at preventing bile duct injury is laparoscopic partial cholecystectomy (LPC). The safety and efficacy of this procedure are unclear.

The impact of maternal age on the effects of prenatal alcohol exposure on attention.

Background: Prenatal exposure to alcohol has a variety of morphologic and neurobehavioral consequences, yet more than 10% of women continue to drink during pregnancy, placing their offspring at risk for fetal alcohol spectrum disorders (FASD). Identification of at-risk pregnancies has been difficult, in part, because the presence and severity of FASD are influenced by factors beyond the pattern of alcohol consumption. Establishing maternal characteristics, such as maternal age, that increase the risk of FASD is critical for targeted pregnancy intervention.

Validation of the Functional Status II questionnaire in the assessment of extremely-low-birthweight infants.

Aim: The increased survival of infants born at extremely low birthweight (ELBW) has been associated with significant morbidity, including higher rates of neurodevelopmental disability. However, formalized testing to evaluate these problems is both time-consuming and costly. The revised Functional Status questionnaire (FS-II) was designed to assess caregivers' perceptions of the functional status of children with chronic diseases.

Spontaneous bilateral internal carotid artery dissection.

Spontaneous internal carotid artery dissection is not an uncommon cause of ischaemic stroke in younger patients, but multiple cervical arterial dissections at presentation are uncommon. Recurrence of dissection in a previously normal artery is common. In this case report we review the history, clinical findings and management of a 42-year-old woman who presented with stroke and Horner syndrome and was found to have spontaneous bilateral internal carotid artery dissection.
