New Hydrogels Nanocomposites Based on Chitosan, 2-Formylphenylboronic Acid, and ZnO Nanoparticles as Promising Disinfectants for Duodenoscopes Reprocessing. Polymers (Basel) 2023; 15:2669. [PMID: 37376315 DOI: 10.3390/polym15122669] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2023] [Revised: 06/09/2023] [Accepted: 06/12/2023] [Indexed: 06/29/2023] Open
Abstract
New hydrogels nanocomposites, based on iminoboronate hydrogels and ZnO nanoparticles (ZnO-NPs), were obtained and characterised in order to develop a new class of disinfectants able to fight the nosocomial infections produced by duodenoscopes investigation procedures. The formation of the imine linkages between chitosan and the aldehyde was demonstrated using NMR and FTIR spectroscopy, while the supramolecular architecture of the developed systems was evaluated via wide-angle X-ray diffraction and polarised optical microscopy. The morphological characterisation of the systems via scanning electron microscopy revealed the highly porous structure of the materials, in which no ZnO agglomeration could be observed, indicating the very fine and homogenous encapsulation of the nanoparticles into the hydrogels. The newly synthetised hydrogels nanocomposites was proven to have synergistic antimicrobial properties, being very efficient as disinfectants against reference strains as: Enterococcus faecalis, Klebsiella pneumoniae, and Candida albicans.

Severe Acute Pancreatitis Treated with Negative Pressure Wound Therapy System: Influence of Laboratory Markers. J Clin Med 2023; 12:jcm12113721. [PMID: 37297916 DOI: 10.3390/jcm12113721] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2023] [Revised: 05/21/2023] [Accepted: 05/24/2023] [Indexed: 06/12/2023] Open
Abstract
(1) Background: An open abdomen is a serious medical condition that requires prompt and effective treatment to prevent complications and improve patient outcomes. Negative pressure therapy (NPT) has emerged as a viable therapeutic option for temporary closure of the abdomen, offering several benefits over traditional methods. (2) Methods: We included 15 patients with pancreatitis who were hospitalized in the I-II Surgery Clinic of the Emergency County Hospital "St. Spiridon" from Iasi, Romania, between 2011-2018 and received NPT. (3) Results: Preoperatively, the mean IAP level was 28.62 mmHg, decreasing significantly postoperatively to 21.31 mmHg. The mean level of the highest IAP value recorded in pancreatitis patients treated with VAC did not differ significantly by lethality (30.31 vs. 28.50; p = 0.810). In vacuum-treated pancreatitis patients with a IAP level > 12, the probability of survival dropped below 50% during the first 7 days of stay in the ICU, so that after 20 days the probability of survival was approximately 20%. IAP enters the determinism of surgery with a sensitivity of 92.3% and a specificity of 99%, the cut-off value of IAP being 15 mmHg. (4) Conclusions: The timing of surgical decompression in abdominal compartment syndrome is very important. Consequently, it is vital to identify a parameter, easy to measure, within the reach of any clinician, so that the indication for surgical intervention can be made judiciously and without delay.

Clostridium difficile Infections in an Emergency Surgical Unit from North-East Romania. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:medicina59050830. [PMID: 37241061 DOI: 10.3390/medicina59050830] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/09/2023] [Revised: 04/19/2023] [Accepted: 04/23/2023] [Indexed: 05/28/2023]
Abstract
Background and Objectives: Colitis with Clostridium difficile is an important health problem that occurs with an intensity that varies between mild and severe. Surgical interventions are required only in fulminant forms. There is little evidence regarding the best surgical intervention in these cases. Materials and Methods: Patients with C. difficile infection were identified from the two surgery clinics from the 'Saint Spiridon' Emergency Hospital Iași, Romania. Data regarding the presentation, indication for surgery, antibiotic therapy, type of toxins, and post-operative outcomes were collected over a 3-year period. Results: From a total of 12,432 patients admitted for emergency or elective surgery, 140 (1.12%) were diagnosed with C. difficile infection. The mortality rate was 14% (20 cases). Non-survivors had higher rates of lower-limb amputations, bowel resections, hepatectomy, and splenectomy. Additional surgery was necessary in 2.8% of cases because of the complications of C. difficile colitis. In three cases, terminal colostomy was performed and as well as one case with subtotal colectomy with ileostomy. All patients who required the second surgery died within the 30-day mortality period. Conclusions: In our prospective study, the incidence was increased both in cases of patients with interventions on the colon and in those requiring limb amputations. Surgical interventions are rarely required in patients with C. difficile colitis.

Gut Microbiota in Chronic Kidney Disease: From Composition to Modulation towards Better Outcomes-A Systematic Review. J Clin Med 2023; 12:jcm12051948. [PMID: 36902734 PMCID: PMC10003930 DOI: 10.3390/jcm12051948] [Citation(s) in RCA: 10] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2023] [Revised: 02/22/2023] [Accepted: 02/27/2023] [Indexed: 03/06/2023] Open
Abstract
BACKGROUND A bidirectional kidney-gut axis was described in patients with chronic kidney disease (CKD). On the one hand, gut dysbiosis could promote CKD progression, but on the other hand, studies reported specific gut microbiota alterations linked to CKD. Therefore, we aimed to systematically review the literature on gut microbiota composition in CKD patients, including those with advanced CKD stages and end-stage kidney disease (ESKD), possibilities to shift gut microbiota, and its impact on clinical outcomes. MATERIALS AND METHODS We performed a literature search in MEDLINE, Embase, Scopus, and Cochrane databases to find eligible studies using pre-specified keywords. Additionally, key inclusion and exclusion criteria were pre-defined to guide the eligibility assessment. RESULTS We retrieved 69 eligible studies which met all inclusion criteria and were analyzed in the present systematic review. Microbiota diversity was decreased in CKD patients as compared to healthy individuals. Ruminococcus and Roseburia had good power to discriminate between CKD patients and healthy controls (AUC = 0.771 and AUC = 0.803, respectively). Roseburia abundance was consistently decreased in CKD patients, especially in those with ESKD (p < 0.001). A model based on 25 microbiota dissimilarities had an excellent predictive power for diabetic nephropathy (AUC = 0.972). Several microbiota patterns were observed in deceased ESKD patients as compared to the survivor group (increased Lactobacillus, Yersinia, and decreased Bacteroides and Phascolarctobacterium levels). Additionally, gut dysbiosis was associated with peritonitis and enhanced inflammatory activity. In addition, some studies documented a beneficial effect on gut flora composition attributed to synbiotic and probiotic therapies. Large randomized clinical trials are required to investigate the impact of different microbiota modulation strategies on gut microflora composition and subsequent clinical outcomes. CONCLUSIONS Patients with CKD had an altered gut microbiome profile, even at early disease stages. Different abundance at genera and species levels could be used in clinical models to discriminate between healthy individuals and patients with CKD. ESKD patients with an increased mortality risk could be identified through gut microbiota analysis. Modulation therapy studies are warranted.

Risk Predictors of Advanced Fibrosis in Non-Alcoholic Fatty Liver Disease. Diagnostics (Basel) 2022; 12:2136. [PMID: 36140537 PMCID: PMC9498120 DOI: 10.3390/diagnostics12092136] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2022] [Revised: 08/22/2022] [Accepted: 08/29/2022] [Indexed: 11/16/2022] Open
Abstract
The assessment of fibrosis in chronic liver diseases using non-invasive methods is an important topic in hepatology. The aim of this study is to identify patients with non-alcoholic fatty liver disease (NAFLD) and advanced liver fibrosis by establishing correlations between biological/ultrasound markers and non-invasively measured liver stiffness. This study enrolled 116 patients with non-alcoholic fatty liver disease, which were evaluated clinically, biologically, and by ultrasound. Liver fibrosis was quantified by measuring liver stiffness by shear wave elastography (SWE). Multiple correlation analysis of predictors of liver fibrosis identified a number of clinical, biological, and ultrasound parameters (BMI, blood glucose, albumin, platelet count, portal vein diameter, bipolar spleen diameter) that are associated with advanced liver fibrosis in patients with non-alcoholic fatty liver disease. The correlations between the degree of liver fibrosis and the risk values of some serological and ultrasound markers obtained in our study could be useful in clinical practice for the identification of advanced fibrosis in patients with NAFLD.

Endoscopic Management of Biliary Strictures after Orthotopic Liver Transplantation: A Single Center Experience Study. Diagnostics (Basel) 2022; 12:diagnostics12051221. [PMID: 35626376 PMCID: PMC9140460 DOI: 10.3390/diagnostics12051221] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2022] [Revised: 04/17/2022] [Accepted: 05/12/2022] [Indexed: 12/04/2022] Open
Abstract
Background and Aim. Endoscopic therapy is the method of choice in the management of biliary strictures after orthotopic liver transplantation (OLT). Even though the mainstay approach for OLT stricture complications is represented by consecutive procedures of multiple plastic stents (MPS) insertion, a valuable alternative is the use of fully covered self-expandable metal stents (FCSEMS). The aim of the study was to compare MPS with FCSEMS used in the management of OLT biliary strictures, in terms of clinical outcomes and complications. Material and Methods. This is a retrospective, single-center study conducted between February 2014 and November 2019 in the Clinical Emergency Hospital of Bucharest, Romania. We enrolled all consecutive patients who developed biliary strictures after OLT and were treated by endoscopic retrograde cholangiopancreatography (ERCP) either with MPS or FCSEMS. Results. Thirty-six patients were included in the study, 27 patients had MPS and nine patients had FCSEMS. 106 ERCP procedures were performed and 159 stents were inserted. The mean number of ERCP procedures required per patient was significantly higher for MPS than for FCSEMS (3.34 ± 1.46 vs. 2.11 ± 0.33, p < 0.001). In the FCSEMS group only one patient had three procedures, due to stent migration. Difficult cannulation was encountered in 22 patients, 18 patients from MPS group and four patients from FCSEMS group. Dilation was performed in 20 (77%) MPS patients and in four FCSEMS patients (44%). Overall, we used 159 stents for stricture resolution, 149 plastic stents and 10 FCSEMS. Mean number of stents inserted was significantly lower in the FCSEMS group compared to MPS group (1.16 ± 0.40 vs. 5.73 ± 2.64, p < 0.001). Conclusions. Stricture resolution using FCSEMS is comparable to MPS and even has some advantages. In line with prior studies, FCSEMS are effective, with fewer complications and similar outcome compared to plastic stents. Other particular aspects should be further assessed, especially long-term follow up of FCSEMS and their cost efficiency.

Magnesium-A Potential Key Player in Inflammatory Bowel Diseases? Nutrients 2022; 14:nu14091914. [PMID: 35565881 PMCID: PMC9102374 DOI: 10.3390/nu14091914] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2022] [Revised: 04/28/2022] [Accepted: 04/29/2022] [Indexed: 02/05/2023] Open
Abstract
The altered magnesium status in inflammatory bowel disease (IBD) patients may have a significant clinical imprint considering its role in cell signaling and genomic stability, as well as its involvement in IBD patients' fatigue. Our study pioneers the investigation of magnesium hair concentration patterns in an adult population of IBD patients. The hair magnesium concentration in IBD patients is compared to healthy controls in order to identify correlations between the magnesium status and relevant parameters related to disease activity, psychological status, and sleep quality. We report a significantly lower hair magnesium concentration within the IBD group compared to healthy controls (95%CI: 0.006-0.062; p = 0.017) and lower levels in CD compared to UC (95%CI: -0.061--0.002; p = 0.038). We identified a borderline statistical significance between the hair magnesium concentration and UC disease activity (95%CI; -0.679-0.008; p = 0.055) and a significantly lower magnesium concentration in patients who reported increased sleep latency (95%CI -0.65--0.102; p = 0.011) or decreased sleep duration (95%CI -0.613--0.041; p = 0.028). Our results advance several hypotheses with substantial clinical impact to be confirmed in future studies. Magnesium levels appear to be modified in IBD patients, which suggests it either plays a primary role in disease pathophysiology or a is result of the disease's evolution. Magnesium could be used in predictive models for clinical/subclinical disease activity. Moreover, magnesium supplementation may improve IBD evolution and sleep quality for patients with a deficit of this mineral. However, confirmatory evidence-based studies are needed to generate specific dosing, time of supplementation, and optimum monitoring of magnesium status in IBD patients.

Abstract
Micronutrient deficiencies can arise in various conditions, including inflammatory bowel diseases (IBD), and diagnosing these deficiencies can be challenging in the absence of specific clinical signs. The aim of this study was to evaluate the status of various trace elements hair concentration in IBD patients compared to a healthy control group and to identify potential correlations between the micronutrient status and relevant parameters related to disease activity. The concentrations of iron, magnesium, calcium, zinc, copper, manganese, selenium and sulfur in the hair of 37 IBD patients with prior diagnosed IBD (12 Crohn's disease and 25 ulcerative colitis) and 31 healthy controls were evaluated by Energy Dispersive X-Ray spectroscopy (EDX). Significant differences in hair concentration profile of studied trace elements were identified for IBD patients compared to healthy controls. A significantly decreased hair concentration of iron, magnesium, calcium and selenium and a significantly increased sulfur hair concentration were observed in IBD patients at the time of evaluation. A decreased hair calcium concentration (r = -0.772, p = 0.003) and an increased sulfur concentration (r = 0.585, p = 0.046) were significantly correlated with disease activity. Conclusion: Hair mineral and trace elements evaluation may contribute to a proper evaluation of their status in IBD patients and improving the management of nutritional status of IBD patients.

Abstract
BACKGROUND The outbreak of the coronavirus disease 2019 (COVID-19) has led to significant changes in endoscopy units worldwide, with potential impact on patients' welfare as well as on endoscopy training. We aimed to assess the real-life impact of COVID-19 on the endoscopy unit in a tertiary care center from Romania. METHODS A 6.5-month period during the COVID-19 pandemic was compared to a similar period from 2019. RESULTS A 6.2-fold decrease of endoscopic procedures was noted. Colonoscopies were reduced from 916 to 42, p < 0.001; flexible sigmoidoscopies from 189 to 14, p = 0.009; upper gastrointestinal (GI) endoscopies from 2269 to 401, p = 0.006; and ERCP from 234 to 125, p < 0.001. The percentage of emergency procedures increased (38.8% vs. 26.2%, p < 0.001), as well as the rate of endoscopies performed for upper GI bleeding (42.5% vs. 24.4%, respectively, p < 0.001). The detection of cancers was considerably reduced (57 compared to 249, p = 0.001). There were fewer complications and higher success rates (7.6% vs. 19.2%, p < 0.001, and 94.2% vs. 90.7%, respectively). Fellows participation was also reduced from 90% to 40.9% (p < 0.001). CONCLUSIONS The COVID-19 pandemic has significantly altered the workflow of the endoscopy unit, lowering the number of procedures performed and potentially compromising the early detection of cancers.

Abstract
The novel COVID-19 infection has spread all over the world and is still generating a lot of issues at different levels. There is a lack of control in disease early diagnosis and rapid evolution, which impacts both the medical and the economic system. Young gastroenterologists should adapt to overcome current difficulties and continue their life and general training. This is a multi-center national study, which aims to assess the general perspective of young gastroenterologists (residents and young specialists) from six university centers in Romania regarding their current training and the psychological effect the pandemic has on their life and job. An online survey with 58 items was distributed using Google Forms, and quality of life and anxiety were assessed. The validated instruments 15D (for assessing the health-related quality of life) and endler multidimensional anxiety scales (EMAS-for assessing anxiety) were used. All analyses were performed using SPSS 25. Of the 174 gastroenterologists approached, 96 (response rate of 55%) responded. A majority of the respondents were residents in gastroenterology (64%), and 40.6% were male. The pandemic influenced the number of examined patients as well as young gastroenterologists' endoscopy training. Health-related quality of life was negatively associated with the level of anxiety generated by the cognitive component of anxiety as a state, the new and ambiguity of the state, and how threatened the respondent felt. The level of anxiety was moderate (median = 51), and no difference was found between the physicians working in a designated hospital or not. General caution should be considered for young gastroenterologists' training, and continuous observation should be done to ensure better mental health on the current evolution. These findings would need to be verified in larger-sample studies and in different types of specialties.

Abstract
Background and Objectives: Over the last years, inflammatory bowel disease (IBD) has been reported on a high incidence in pediatric populations and has been associated with numerous extraintestinal manifestations, making its management a real challenge for the pediatric gastroenterologist. Dermatological manifestations in IBD are either specific, related to the disease activity or treatment-associated, or non-specific. This literature review aims to identify and report the dermatological manifestations of IBD in children, the correlation between their appearance and the demographical characteristics, the relationship between these lesions and disease activity, and to highlight the impact of dermatological manifestations on an IBD treatment regime. Materials and Methods: A systemic literature review was performed, investigating articles and case reports on dermatological manifestations in children with IBD starting from 2005. A total of 159 potentially suitable articles were identified and after the exclusion process, 75 articles were selected. Results: The most common dermatological manifestations reported in pediatric IBD are erythema nodosum and pyoderma gangrenosum. More rare cases of metastatic Crohn’s disease, epidermolysis bullosa acquisita, small-vessel vasculitis, necrotizing vasculitis, leukocytoclastic vasculitis, cutaneous polyarteritis nodosa, and Sweet’s syndrome have been reported. Oral manifestations of IBD are divided into specific (tag-like lesions, mucogingivitis, lip swelling with vertical fissures, aphthous stomatitis, and pyostomatitis vegetans) and non-specific. IBD treatment may present with side effects involving the skin and mucosa. Anti-tumor necrosis factor agents have been linked to opportunistic skin infections, psoriasiform lesions, and a potentially increased risk for skin cancer. Cutaneous manifestations such as acrodermatitis enteropathica, purpuric lesions, and angular cheilitis may appear secondary to malnutrition and/or malabsorption. Conclusions: The correct diagnosis of dermatological manifestations in pediatric IBD is of paramount importance because of their impact on disease activity, treatment options, and a patient’s psychological status.

Abstract
BACKGROUND AND AIMS The coexistence of RAS and BRAF mutations is extremely rare, occurring in approximately 0.05% of patients with metastatic colorectal cancer (mCRC). Starting from a case presentation, this review aims to examine the prevalence, clinical, histopathological and molecular features of tumors with concomitant mutations. METHODS Case report and systematic review. We performed a systematic literature search in PubMed and EMBASE using the following MeSH terms: "coexistence" OR "concomitant" AND "RAS" AND "BRAF" AND "colorectal cancer" from the inception of the databases onwards. RESULTS We present the case of a 53-year-old man diagnosed with metastatic rectal adenocarcinoma with both a KRAS and a BRAF mutation. The review included eleven papers reporting on a total of 30 mCRC cases with concomitant RAS and BRAF mutations. The male/female ratio was 11/5. The average age was 58.5 years. The tumor was located in nine cases on the right colon and in two cases in the left colon. 43.3% of subjects had liver metastases, and 6.6% had lung metastases. Next-generation sequencing (NGS) was used in 36.6% of cases and polymerase chain reaction (PCR) in 16.6% of cases. KRAS mutations were present in 83.3% of patients and NRAS mutations in 16.6% of patients. Survival could be assessed in 10 patients and the median was 21.1 months (about 30% lower than the survival in the general mCRC population). CONCLUSION The results of this systematic review suggest the need to design a cohort study (either prospective or retrospective) to better characterize the patients with concomitant RAS and BRAF mutations and to establish the optimal treatment for this rare situation.

Abstract
BACKGROUND Endoscopic retrograde cholangiopancreatography (ERCP) has been one of the most intensely studied endoscopic procedures due to its overall high complication rates when compared to other digestive endoscopy procedures. The safety and outcome of such procedures have been linked to multiple procedure- or patient-related risk factors. The aim of our study is to evaluate whether the morphology of the major duodenal papilla influences the ERCP outcomes and complication rates. METHODS A total of 322 patients with a native papilla have been included in the study over an eight month period. Morphology of the papilla has been classified into normal papilla and four anatomical variations (Type I-IV). All patients have been prospectively monitored over a 15 day period after ERCP. Procedural outcomes and complication rates have been registered. RESULTS Morphology of the papilla influences both overall complication rates (95%CI, p = 0.0066) and post-ERCP pancreatitis rates (95%CI, p = 0.01001) in univariate analysis. Type IV papillae have proven to be independent risk factors for post-ERCP pancreatitis in multivariate analysis (OR = 12.176, 95%CI, p = 0.005). Type I papillae have been significantly linked to difficult cannulation (AUC = 0.591, 95%CI, p = 0.008); Conclusions: In the monitored cohort morphology of the major duodenal papilla has significantly influenced both ERCP outcomes and post-procedural complication rates.

Abstract
BACKGROUND AND OBJECTIVES The laparoscopic gastric plication (LGP) is a restrictive bariatric procedure, still under investigation, considered to be an alternative to laparoscopic sleeve gastrectomy (LSG). The aim of the present study was to compare the outcome of LGP with the results of LSG. Materials and Methods: The study was conducted on a total of 100 patients, from which 50 patients underwent LGP and other 50 patients had the LSG operation. To analyze the effectiveness of both procedures total weight loss (%TWL), change in body mass index ( BMI) and percentage of excess weight loss (%EWL) were measured and calculated for four distinct timelines: 6 months, 12 months, 24 months and 36 months after the procedure. Comorbidities were evaluated based on clinical and laboratory investigation. Results: Starting from 6 months after surgery, weight reduction was statistically significant in favor of the LSG group, with the highest differences found after two and three years postoperatively (p=0.0001). No differences were found between the two procedures in terms of compliance or improvement of the main comorbidities. Conclusions: As compared to LSG, LGP has similar outcomes in terms of the length of hospitalization, major complications and improvement of the main comorbidities. LSG procedure was found to be superior in terms of medium- to long-term weight reduction. LGP is a technique that may provide better results in obese patients with a lower BMI (less than 40 kg/m2).

Abstract
Flexible digestive endoscopes are used for the management of various conditions with hundreds of thousands of therapeutic procedures performed worldwide each year. Duodenoscopes are indispensable tools for the delivery of minimally invasive vital care of numerous pancreaticobiliary disorders. Despite the fact that nosocomial infections after endoscopic retrograde cholangiopancreatography (ERCP) have always been among the most frequently cited postprocedural complications, recent emergence of duodenoscope-transmitted multiple drug-resistant bacterial infections has led to intense research and debate yet with no clearly delineated solution. Duodenoscope-transmitted nosocomial infections have become one of the most visible topics in the recent literature. Hundreds of high-impact articles have therefore been published in the last decade. This review article discusses how such infections were seen in the past and what is the current situation in both research and practice and thus tries to solve some of the unanswered questions for the future. With the persistence of nosocomial infections despite strict adherence to both manufacturer-issued reprocessing protocols and international guidelines and regulations, an urgent and proper microbiologically driven common action is needed for controlling such nosocomial worldwide threat.

Abstract
Obesity is a major cause of adipose tissue (AT) inflammation. Ghrelin (GHRL), through its growth hormone secretagogue receptor (GHS-R) present on adipose tissue macrophages (ATMs), could modulate AT inflammation.

Duodenoscope-Associated Infections beyond the Elevator Channel: Alternative Causes for Difficult Reprocessing. Molecules 2019; 24:molecules24122343. [PMID: 31242689 PMCID: PMC6631070 DOI: 10.3390/molecules24122343] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2019] [Revised: 06/21/2019] [Accepted: 06/25/2019] [Indexed: 02/05/2023] Open
Abstract
OBJECTIVES Duodenoscopes have been widely used for both diagnostic and therapeutic endoscopic retrograde cholangiopancreatography (ERCP) procedures, but recently, numerous outbreaks of multidrug-resistant organisms (MDRO) infections have been reported which has led to extensive research for their possible causes. Consequently, the aim of this study is to search for possible duodenoscope surface damages that could provide an alternative and plausible source of infections. MATERIALS AND METHODS In order to assess both outer and inner surfaces, a duodenoscope was dismantled and samples were taken from the outer resin polymer and from the air/water, elevator, and working (biopsy) channels that were characterized by FTIR, DSC, TGA, AFM, SEM techniques and the antimicrobial activity were tested. RESULTS Alterations were noticed on both the coating and working channel polymers, with external alterations increasing progressively from the proximal sample to the distal sample near the tip of the scope. However, the results showed that the coating surface was still efficient against bacterial adhesion. Changes in surface texture and also morphological changes were shown. CONCLUSIONS The study describes the impact of routine procedural use and reprocessing cycles on the duodenoscope, showing that these may possibly make it susceptible to bacterial contamination and MDRO biofilm formation due to difficult reprocessing of the altered surfaces.

Abstract
The ability of Berberis vulgaris bark extract (BVE) to improve the lipid profile was evaluated in an experimental model of dyslipidemia, along with its effects on liver and kidney functions. Fifty rats divided into five groups of ten animals each were fed with normal or lard-based diet and orally treated with 0.9% saline solution, atorvastatin (2.5 mg/kg per body weight) or extract of BVE (300 and 500 mg/kg/day) for eight weeks. Lipid profile, liver and renal functions were assessed in normal and diet-induced hypercholesterolemic rats. The results were compared between the groups treated with Berberis extract and the group without treatment, respectively that one treated with the standard drug (atorvastatin). Administration of BVE or atorvastatin significantly decreases the elevated serum lipid profile (p [0.05). The extract also protects against dyslipidemia-induced non-alcoholic fatty liver disease (NAFLD). The activities of the plant extract are dose dependent and it compares favorably with the standard drug atorvastatin. Variations in aspartate aminotransferase (AST), alanine aminotransferase (ALT), and urea level measurements were neither different between the two determinations nor between groups, but creatinine values decreased in rats in the BVE or atorvastatin-treated groups. The findings of the current study have suggested that BVE intake suppresses the accumulation of hepatic lipids and lipid parameters and reduce the risk of NAFLD. So, BVE can be useful in hypercholesterolemia.

Abstract
Choledocholithiasis may cause biliary obstruction which leads to hepatocellular injury. Oxidative stress has been proposed as a possible mechanism involved in this disorder. This study evaluates the oxidative stress burden in patients with choledocholithiasis and secondary cholestasis, before and after endoscopic sphincterotomy. Experimental part: Patients diagnosed with choledocholithiasis and secondary extrahepatic cholestasis were included in the study between January 1st 2016 and October 31st 2016. In all patients oxidative stress markers were collected within 2 hours before and 48 hours after therapeutic ERCP. Selected markers were superoxide dismutase (SOD), glutathione peroxidase (GPX) and malondialdehyde (MDA). The results were compared to those from a group of 40 healthy subjects. Significantly lower concentrations of SOD (p = 0.03) and GPX (p [ 0.0001) activities, associated with an increased level of MDA level (p [ 0.0001) were shown in patients before biliary clearance compared with the healthy control group. After ERCP the only oxidative stress parameter which showed improvement was the SOD specific activity (p = 0.037). This study shows that extrahepatic cholestasis secondary to choledocholithiasis is associated with increased oxidative stress status. After biliary clearance one oxidative stress marker was significantly improved (SOD), suggesting a possible antioxidant effect of such procedure.

Acetylcholinesterase Inhibitors Test Confirmed Myasthenia Gravis in Psychosis Remitted by Aripiprazole. REVISTA DE CHIMIE 2018.

Abstract
Myasthenia gravis (MG) is a chronic autoimmune neuromuscular disease affecting the neuromuscular junction and causes weakness in the skeletal muscles. The acetylcholine receptor is usually attacked in skeletal muscles, but other components of neuromuscular junction, such as muscle-specific receptor tyrosine kinase, may be affected. MG can be life-threatening when the respiratory muscles are involved. The first symptom in about 2 out of 3 cases is the damage of the extrinsic eye muscles. The condition is treatable, so an early recognition is needed. Although there have been reports of associations between psychosis and myasthenia gravis it is unclear if psychotic symptoms in MG are an integral part of the various manifestations of this disease, or are due to another co-occurring distinct disorder. Sometimes psychotic episodes could disguise the simptoms of myastenia gravis, and delay the diagnosis.

Abstract
Introduction of contrast agents as microbubbles and to improve ultrasound examination techniques has increased the rate of detection and characterization of liver lesions. Contrast-enhanced ultrasonography (CEUS) is a relatively new method of exploring the liver and diagnosing focal liver lesions (FLL). The aim of this study is to determine the efficiency of microbubbles used for CEUS in managing patients detected in conventional ultrasonography with FLL. We examined 84 patients with FLL, detected on conventional ultrasonography (US), during October 2012-September 2015. We performed contrast-enhanced ultrasonography, using sulphur hexafluoride as a contrast agent, and contrast-enhanced MRI to set the diagnosis. For 37 patients (44.1%) CEUS showed a malignity pattern of enhancement (according to the EFSUMB - European Federation of Societies for Ultrasound in Medicine and Biology- Guidelines 2012), while for 54 (64.3%) patients MRI set the diagnosis of malignity. CEUS detected fewer malignant lesions than MRI, in 20.1% of the cases MRI set de diagnosis. We need further studies in order to improve the quality of CEUS images and technique.
