Abstract

Background Anal fissure (AF) is a common, painful disease that strongly affects patients’ quality of life, however, no scoring system to assess the severity of AF is available in the literature. The aim of this study was to set up and validate a reliable scoring system to quantify the severity of AF, to be used in prospective trials comparing the efficacy and the outcomes of surgical or medical treatments. Methods The study was conducted on patients with acute or chronic AF and a control group in a tertiary centre for coloproctology in June 2020–September 2020. Two researchers independently carried out a structured interviewer-led questionnaire at two different time points (T1/T2). The questionnaire consisted of five items selected according to the most commonly reported symptoms for AF: the item pain, was scored from 0 to 10 using a visual analogue scale, and quality of life, duration of pain, use of painkillers, and bleeding were scored from 1 to 5 using Likert-scale questions. The scoRing systEm for AnaL fIsSurE (REALISE) score was the sum of the points. Patients with AF and a control group of patients with haemorrhoids, anal fistula, or obstructed defecation syndrome entered the study. Main outcome measures were reliability, inter-/intraobserver agreement, and repeatability. Results One hundred and fifty well-matched patients (75 with AF and 75 controls) were enrolled. A significant difference was found between the mean REALISE score for patients with AF and controls (p r = 0.99). The coefficient of repeatability was 1.45 in T1 and 1.18 in T2. Conclusions The REALISE score may have an important role in the assessment and management of AF, in grading the severity of AF and comparing results of different treatments.

Abstract

One of the most controversial issues surrounding laparoscopic sleeve gastrectomy is the development of gastroesophageal reflux disease following surgery. The aim of the study was to evaluate the occurrence of gastroesophageal reflux disease after laparoscopic sleeve gastrectomy and to analyze patients' weight loss, comorbidities, and quality of life after surgery.The clinical records of 52 patients submitted to laparoscopic sleeve gastrectomy between January and November 2018, with 3 years of follow-up, were retrospectively reviewed. At the end of the follow-up period, the patients underwent screening endoscopy, and those with postoperative esophagitis were submitted to endoscopic biopsies and pH-impedance monitoring (MII-pH). The presence of gastroesophageal reflux disease symptoms was assessed using the modified clinical DeMesteer score questionnaire. The Bariatric Analysis and Reporting Outcome System score and 36-Item Short Form Health Survey were used to assess the postoperative quality of life.In the preoperative work-up, only 7.6% of patients had signs of esophagitis at esophagogastroduodenoscopy, whilst at 3-year follow-up, 50% of them had endoscopic signs of gastroesophageal reflux disease. Twenty-one out of 26 patients with signs of esophagitis agreed to undergo MII-pH. The median DeMesteer score questionnaire was 4.5, with only 4 patients (19%) exhibiting a value greater than the pH cut-off value (14.72), indicative of gastroesophageal reflux disease. MII-pH data analysis showed the presence of gastroesophageal reflux disease in 5 patients. An excellent outcome on the Bariatric Analysis and Reporting Outcome System score was reported in 50% of patients, and all 8 domains from the 36-Item Short Form Health Survey improved significantly.This study showed an improvement in these patients' quality of life and the limited refluxogenic nature of laparoscopic sleeve gastrectomy at 3-year follow-up when diagnosis of gastroesophageal reflux disease is based on the Lyon consensus.

Abstract

Background The development of fast internet connection has stimulated different types of video-assisted teaching programs. However, a remote mentoring with the proctor not on site has never been reported in bariatric surgery. We described our experiences with remote telementoring for laparoscopic sleeve gastrectomy. Methods A qualified general surgeon at the beginning of his bariatric practice performed a series of 8 laparoscopic sleeve gastrectomies (LSG) while tutored by an experienced bariatric surgeon connected from a different city through a specific videoconferencing platform. Data on demographics at baseline, operative time, hospital stay, intraoperative early, and late complications were collected. Results Mean age and BMI of patients were 36.9 ± 9.6 years old and 41.8 ± 1.7 kg/m2. All procedures were carried out without conversion to open or complications. Mean operative time was 112.4 ± 21.9 min while the hospital stay was 3.5 ± 0.5 days. Operative time significantly decreased after the fourth operation. Conclusions Remote coaching appears to be possible and safe for LSG.

Abstract

Background The incidence of the highly morbid and potentially lethal gangrenous cholecystitis was reportedly increased during the COVID-19 pandemic. The aim of the ChoCO-W study was to compare the clinical findings and outcomes of acute cholecystitis in patients who had COVID-19 disease with those who did not. Methods Data were prospectively collected over 6 months (October 1, 2020, to April 30, 2021) with 1-month follow-up. In October 2020, Delta variant of SARS CoV-2 was isolated for the first time. Demographic and clinical data were analyzed and reported according to the STROBE guidelines. Baseline characteristics and clinical outcomes of patients who had COVID-19 were compared with those who did not. Results A total of 2893 patients, from 42 countries, 218 centers, involved, with a median age of 61.3 (SD: 17.39) years were prospectively enrolled in this study; 1481 (51%) patients were males. One hundred and eighty (6.9%) patients were COVID-19 positive, while 2412 (93.1%) were negative. Concomitant preexisting diseases including cardiovascular diseases (p p p = 0.005) were significantly more frequent in the COVID-19 group. Markers of sepsis severity including ARDS (p p p p p p p p p Conclusions The incidence of gangrenous cholecystitis is higher in COVID patients compared with non-COVID patients admitted to the emergency department with acute cholecystitis. Gangrenous cholecystitis in COVID patients is associated with high-grade Clavien-Dindo postoperative complications, longer hospital stay and higher mortality rate. The open cholecystectomy rate is higher in COVID compared with non -COVID patients. It is recommended to delay the surgical treatment in COVID patients, when it is possible, to decrease morbidity and mortality rates. COVID-19 infection and gangrenous cholecystistis are not absolute contraindications to perform laparoscopic cholecystectomy, in a case by case evaluation, in expert hands. Graphical abstract

Abstract

Background/objectives: Reports about the implementation of recommendations from acute pancreatitis guidelines are scant. This study aimed to evaluate, on a patient-data basis, the contemporary practice patterns of management of biliary acute pancreatitis and to compare these practices with the recommendations by the most updated guidelines. Methods: All consecutive patients admitted to any of the 150 participating general surgery (GS), hepatopancreatobiliary surgery (HPB), internal medicine (IM) and gastroenterology (GA) departments with a diagnosis of biliary acute pancreatitis between 01/01/2019 and 31/12/2020 were included in the study. Categorical data were reported as percentages representing the proportion of all study patients or different and well-defined cohorts for each variable. Continuous data were expressed as mean and standard deviation. Differences between the compliance obtained in the four different subgroups were compared using the Mann-Whitney U, Student's t, ANOVA or Kruskal-Wallis tests for continuous data, and the Chi-square test or the Fisher's exact test for categorical data. Results: Complete data were available for 5275 patients. The most commonly discordant gaps between daily clinical practice and recommendations included the optimal timing for the index CT scan (6.1%, χ2 6.71, P = 0.081), use of prophylactic antibiotics (44.2%, χ2 221.05, P < 0.00001), early enteral feeding (33.2%, χ2 11.51, P = 0.009), and the implementation of early cholecystectomy strategies (29%, χ2 354.64, P < 0.00001), with wide variability based on the admitting speciality. Conclusions: The results of this study showed an overall poor compliance with evidence-based guidelines in the management of ABP, with wide variability based on the admitting speciality. Study protocol registered in ClinicalTrials.Gov (ID Number NCT04747990).

Abstract

Postoperative bleeding is a common complication after endoscopic polypectomy, particularly after endoscopic mucosal resection (EMR) of large non-pedunculated polyps, despite prophylactic clipping can reduce its occurrence. Cyanoacrylate glue has recently been proposed as a useful tool in reducing bleeding in surgery because of its adhesive and haemostatic properties. The aim of this study is to evaluate the usefulness of endoscopic application of a modified cyanoacrylate glue in the prevention of early or delayed post EMR bleeding. This is a pilot study. Inclusion criteria were patients between 18 and 75 years old affected by sessile or flat colonic polyps larger than 2 cm. Patients enrolled in the study were randomized in two groups: group A (EMR) and group B (EMR with the application of 0.3 ml of N-butyl-2-cyanoacrylate + methacryloxysulfolane—Glubran 2®). Fifteen patients in both group A and B were enrolled. There were no intraoperative complications but haemostatic clipping was necessary in 3 patients in each group because of active bleeding. Delayed (after 24 h) bleeding occurred in two patients (13.3%) in group A requiring hospital readmission and re-do endoscopy with apposition of haemostatic clips. No case of bleeding was recorded in group B (p = 0.48). The results of this pilot study suggest a potential role of local spray application of Glubran®2 in reducing post-procedural bleeding.

Abstract

Debridement is the process of removal of necrotic and infected tissue to clean a wound or burn and expedite healing. Proteases such as papain, bromelain, and collagenase that promote debridement by degrading proteins in the dead tissue are in use today. However, the only method to measure debriding efficacy in vitro is the fluorescent monitoring of the digestion of an Artificial Wound Eschar (AWE) substrate. This AWE substrate contains a pellet of only three eschar matrix proteins collagen, elastin, and fibrin which do not account for the complexity and the composition of necrotic tissue. Here, we describe an ex vivo method using dry necrotic full thickness human skin and ortho-phthalaldehyde (OPA), a molecule commonly used for sensitive fluorimetric protein detection to monitor debridement activity. We advocate this simple yet sensitive approach to detect debridement efficacy that can readily be used commercially to benchmark products prior to in vivo testing.

Abstract

Patient: Female, 60-year-old Final Diagnosis: Pneumatosis intestinalis Symptoms: Abdominal pain Medication:— Clinical Procedure: — Specialty: Surgery Objective: Rare co-existance of disease or pathology Background: Hepatic portal venous gas (HPVG) associated with pneumatosis intestinalis (PI) can be indicative of several diseases, including inflammatory bowel disease (IBD), infective and obstructive gastrointestinal conditions, and also potentially life-threatening situations such as mesenteric ischemia. Case Report: A 60-year-old female patient came to our attention with evidence at computed tomography (CT) scan of gas in the portal vein and bowel walls with no sign of ischemia. General tenderness of the abdomen with absence of bowel sounds was detected at the physical examination. An exploratory laparotomy was performed with evidence of mesenteric ischemia. Conclusions: Emergency surgery should be indicated when CT signs of PI and HPVG occur along with a clinical situation strongly suggestive of bowel ischemia, even with no radiological sign of this critical condition.

Abstract

A cancer cell-targeting fluorescent sensor has been developed to image mobile Zn2+ by introducing a biotin group. It shows a highly selective response to Zn2+in vitro, no toxicity in cellulo and images 'mobile' Zn2+ specifically in cancer cells. We believe this probe has the potential to help improve our understanding of the role of Zn2+ in the processes of cancer initiation and development.

Abstract

A single-nucleotide polymorphism (SNP) in exon 4 results in expression of either arginine (72R) or proline (72P) at codon 72 of p53. We demonstrate that the in vitro response of cells exposed to anticancer agents is strongly influenced by this SNP in wild-type p53. In inducible systems and in cells expressing the endogenous protein, expression of 72P wild-type p53 results in a predominant G1 arrest, with only a minor apoptosis, at drug concentrations causing extensive apoptosis in cells expressing the 72R wild-type variant. The superior apoptosis-inducing activity of the 72R form correlates with more efficient induction of specific apoptosis-associated genes, and is maximal in the presence of serine 46 (S46). In vivo, the outcome of chemo-radiotherapy of squamous carcinomas is more favourable in cancers retaining a wild-type 72R allele, such cases having higher response rates and longer survival than those with wild-type 72P. Together, these results reveal that this SNP is an important determinant of response to anticancer agents in cells expressing wild-type p53. Analysis of complete p53 genotype (mutation and SNP) merits detailed investigation as a simple means for prediction of treatment response and survival in clinical oncology.

Abstract

The insulin/insulin-like growth factor (IGF) signaling pathway to mTOR is essential for the survival and growth of normal cells and also contributes to the genesis and progression of cancer. This signaling pathway is linked with regulation of mitochondrial function, but how is incompletely understood. Here we show that IGF-I and insulin induce rapid transcription of the mitochondrial pyrimidine nucleotide carrier PNC1, which shares significant identity with the essential yeast mitochondrial carrier Rim2p. PNC1 expression is dependent on PI-3 kinase and mTOR activity and is higher in transformed fibroblasts, cancer cell lines, and primary prostate cancers than in normal tissues. Overexpression of PNC1 enhances cell size, whereas suppression of PNC1 expression causes reduced cell size and retarded cell cycle progression and proliferation. Cells with reduced PNC1 expression have reduced mitochondrial UTP levels, but while mitochondrial membrane potential and cellular ATP are not altered, cellular ROS levels are increased. Overall the data indicate that PNC1 is a target of the IGF-I/mTOR pathway that is essential for mitochondrial activity in regulating cell growth and proliferation.

Abstract

Uncontrolled hedgehog (HH)/glioma-associated oncogene (GLI) and WNT/β-catenin signaling are important events in the genesis of many cancers including skin cancer and are often implicated in tumor progression, invasion, and metastasis. However, because of the complexity and context dependency of both pathways, little is known about HH and WNT interactions in human carcinogenesis. In the current study, we provide evidence of HH/glioma-associated oncogene family zinc finger 2 (GLI2)-WNT/β-catenin signaling crosstalk in human keratinocytes. Overexpression of GLI2ΔN in human keratinocytes resulted in cytoplasmic accumulation and nuclear relocalization of β-catenin in vitro and in 3D organotypic cultures, accompanied by upregulation of WNT genes. Induction of GLI2ΔN enhanced the β-catenin-dependent transcriptional activation and the subsequent activation of β-catenin target genes including cyclin-D1. Additionally, GLI2 overexpression was associated with decreased E-cadherin protein levels; increased expression of SNAIL, matrix metalloproteinase 2, and integrin β1; and increased cell invasion in 3D organotypic cultures. Invasion was reduced by WNT inhibition, thus unveiling the direct role of GLI2/WNT crosstalk in cell invasion. We show that GLI2 overexpression supported long-term epidermal regeneration in 3D organotypic cultures, and resulted in the manifestation of an undifferentiated basal/stem cell-associated phenotype in human keratinocytes. Both these observations are consistent with the role of β-catenin and SNAIL in epidermal stem cell maintenance. This work suggests that GLI2 is a regulator of β-catenin and provides insights into its role in tumorigenesis.

Abstract

Intact p73 function is shown to be an important determinant of cellular sensitivity to anticancer agents. Inhibition of p73 function by dominant-negative proteins or by mutant p53 abrogates apoptosis and cytotoxicity induced by these agents. A polymorphism encoding either arginine (72R) or proline (72P) at codon 72 of p53 influences inhibition of p73 by a range of p53 mutants identified in squamous cancers. Clinical response following cisplatin-based chemo-radiotherapy for advanced head and neck cancer is influenced by this polymorphism, cancers expressing 72R mutants having lower response rates than those expressing 72P mutants. Polymorphism in p53 may influence individual responsiveness to cancer therapy.

Abstract

The impermeability of the cell plasma membrane is a major obstacle to intracellular delivery of large hydrophilic molecules, such as many kinds of drugs. This contribution describes a general-purpose delivery system that employs the membrane fusion capacity of enveloped viruses to circumvent cell impermeability. Vesicles were generated from the plasma membrane of HEp-2 cells, a human cell line host for the Newcastle disease virus (NDV). They could be loaded with a fluorescent, high molecular weight dye (FITC/dextran, MW 70 KDa) or with the enzyme ribonuclease A (MW 14 KDa). These vesicles were found to fuse and deliver their lumen contents to cultured HEp-2 cells in the presence of NDV virions. When ribonuclease was employed as the encapsulated solute, viral replication was inhibited and death of the infected cells was accelerated. Implications and possible applications of this technique in antiviral therapy are discussed.

Abstract

The nucleoside analogue 4-thiothymidine has shown great potential in vitro as a photosensitiser for the photodynamic therapy of numerous cancer cell lines. However, the limited penetrating power of UV-A radiation, to which it responds, raises doubts as to its practical usefulness in clinical applications. We addressed this issue by studying the penetration extent of topical thiothymidine and the antiproliferative effect of its combination with UV-A radiation on ex vivo basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) skin cancer biopsies, and normal skin. Our results show that both the intralesional concentration of the drug and the intensity of UV-A radiation are sufficient to activate the molecule and cause extensive death by apoptosis of the malignant cells. Normal skin biopsies were not significantly affected by the treatment.

Abstract

One of the most frequently mutated genes in human cancers, tumour suppressor p53 (TP53), can induce cell-cycle arrest and apoptosis. The apoptotic function of p53 is tightly linked to its tumour-suppression function and the efficacy of many cancer therapies depends on this. The identification of a new family of proteins, known as ASPPs (ankyrin-repeat-, SH3-domain- and proline-rich-region-containing proteins), has led to the discovery of a novel mechanism that selectively regulates the apoptotic function, but not the cell-cycle-arrest function, of p53, and gives an insight into how p53 responds to different stress signals. ASPPs might be new molecular targets for cancer therapy.

Abstract

The E2F family of transcription factors regulates the expression of a number of genes whose products are involved in cell cycle control, DNA replication and apoptosis. We show here that E2F-1 binds in vivo the promoters of ASPP1 and ASPP2 genes, two activators of p53-mediated apoptosis, E2F-1, E2F-2 and E2F-3 all activate the isolated ASPP1 and ASPP2 promoters. Overexpression or deregulation of E2F-1 increased the expression levels of ASPP1 and ASPP2 mRNA and proteins. The identification of ASPP1 and ASPP2 genes as transcriptional targets of E2F provides another mechanism by which E2F cooperates with p53 to induce apoptosis.

Abstract

We have previously shown that ASPP1 and ASPP2 are specific activators of p53; one mechanism by which wild-type p53 is tolerated in human breast carcinomas is through loss of ASPP activity. We have further shown that 53BP2, which corresponds to a C-terminal fragment of ASPP2, acts as a dominant negative inhibitor of p53 (ref. 1). Hence, an inhibitory form of ASPP resembling 53BP2 could allow cells to bypass the tumor-suppressor functions of p53 and the ASPP proteins. Here, we characterize such a protein, iASPP (inhibitory member of the ASPP family), encoded by PPP1R13L in humans and ape-1 in Caenorhabditis elegans. iASPP is an evolutionarily conserved inhibitor of p53; inhibition of iASPP by RNA-mediated interference or antisense RNA in C. elegans or human cells, respectively, induces p53-dependent apoptosis. Moreover, iASPP is an oncoprotein that cooperates with Ras, E1A and E7, but not mutant p53, to transform cells in vitro. Increased expression of iASPP also confers resistance to ultraviolet radiation and to cisplatin-induced apoptosis. iASPP expression is upregulated in human breast carcinomas expressing wild-type p53 and normal levels of ASPP. Inhibition of iASPP could provide an important new strategy for treating tumors expressing wild-type p53.

Abstract

We identified a family of proteins termed ASPP. ASPP1 is a protein homologous to 53BP2, the C-terminal half of ASPP2. ASPP proteins interact with p53 and specifically enhance p53-induced apoptosis but not cell cycle arrest. Inhibition of endogenous ASPP function suppresses the apoptotic function of endogenous p53 in response to apoptotic stimuli. ASPP enhance the DNA binding and transactivation function of p53 on the promoters of proapoptotic genes in vivo. Two tumor-derived p53 mutants with reduced apoptotic function were defective in cooperating with ASPP in apoptosis induction. The expression of ASPP is frequently downregulated in human breast carcinomas expressing wild-type p53 but not mutant p53. Therefore, ASPP regulate the tumor suppression function of p53 in vivo.

Abstract

Abnormal Sonic Hedgehog signalling leads to increased transcriptional activation of its downstream effector, glioma 2 (GLI2), which is implicated in the pathogenesis of a variety of human cancers. However, the mechanisms underlying the tumorigenic role of GLI2 remain elusive. We demonstrate that overexpression of GLI2-β isoform, which lacks the N-terminal repressor domain (GLI2ΔN) in human keratinocytes is sufficient to induce numerical and structural chromosomal aberrations, including tetraploidy/aneuploidy and chromosomal translocations. This is coupled with suppression of cell cycle regulators p21WAF1/CIP1 and 14-3-3σ, and strong induction of anti-apoptotic signalling, resulting in a reduction in the ability to eliminate genomically abnormal cells. Overexpression of GLI2ΔN also rendered human keratinocytes resistant to UVB-mediated apoptosis, whereas inhibition of B-cell lymphoma 2 (BCL-2) restored endogenous (genomic instability (GIN)) and exogenous (UVB) DNA damage-induced apoptosis. Thus, we propose that ectopic expression of GLI2 profoundly affects the genomic integrity of human epithelial cells and contributes to the survival of progenies with genomic alterations by deregulating cell cycle proteins and disabling the apoptotic mechanisms responsible for their elimination. This study reveals a novel role for GLI2 in promoting GIN, a hallmark of human tumors, and identifies potential mechanisms that may provide new opportunities for the design of novel forms of cancer therapeutic strategies.
