RESUMEN
Purpose: Holmium laser enucleation of the prostate (HoLEP) showed higher efficacy than transurethral resection for treating benign prostatic hyperplasia (BPH). The present study aims to report the outcome of BPH treatment by HoLEP in a tertiary center. Patients and Methods: An observational prospectively collected data for consecutive symptomatic BPH patients undergoing HoLEP between January 2020 and December 2021. Demographic and perioperative data were collected with the International Prostate Symptom Score (IPSS), quality of life, peak flow rate (Qmax), residual urine postvoid residual (PVR), and prostate-specific antigen (PSA) changes, in addition to perioperative and late adverse events. Results: One hundred patients were included with a median age of 73 years (range 65-80). The IPSS improved by 80% postoperatively (25 vs. 5, P < 0.001). Similarly, Qmax significantly improved. Seven patients were found to have incidental prostate cancer. No patient needed a perioperative blood transfusion. Compared to its preoperative values, follow-up PSA has been reduced by 75% (P < 0.001). Urethral stricture and bladder neck contracture were noted in < 2% of the patients. Conclusions: HoLEP is feasible for all prostate sizes and a safe and effective treatment for BPH patients; our results are consistent with the reported data in the literature regarding functional outcomes, complication rates, and urinary incontinence rates.
RESUMEN
BACKGROUND: Risk stratification assessment of patients with non-ST elevation acute coronary syndrome (NSTE ACS) plays an important role in optimal management and defines the patient's prognosis. This study aimed to evaluate the ability of CHA2DS2-VASc-HSF score (comprising of the components of the CHA2DS2-VASc score with a male instead of female sex category, hyperlipidemia, smoking, and family history of coronary artery disease respectively) to predict the severity and complexity of CAD and its efficacy in stratification for major adverse cardiovascular events (MACE) in patients with NSTE ACS without known atrial fibrillation. METHODS: This study included 200 patients (males 72.5%, mean age 55.8 ± 10.1 years) who were admitted with NSTE ACS. CHA2DS2-VASC-HSF score was calculated on admission. Patients were classified into three groups according to their CHA2DS2-VASC-HSF score: low score group (< 2; 29 patients), intermediate score group (2-4; 83 patients), and high score group (≥ 5; 88 patients). Coronary angiography was conducted and the Syntax score (SS) was calculated. Clinical follow-up at 6 months of admission for the development of MACE was recorded. RESULTS: SS was significantly high in the high CHA2DS2-VASc-HSF score group compared with low and intermediate score groups. CHA2DS2-VASc-HSF score had a significant positive strong correlation with syntax score (r = 0.64, P < 0.001). Smoking, vascular disease, hyperlipidemia, and CHA2DS2-VASc-HSF score were independent predictors of high SS. For the prediction of severe and complex CAD, CHA2DS2-VASc-HSF score had a good predictive power at a cut-off value ≥ 5 with a sensitivity of 86% and specificity of 65%. Hypertension, vascular disease, high SS, and CHA2DS2-VASc-HSF score were independent predictors of MACE. CHA2DS2-VASC-HSF score ≥ 4 was identified as an effective cut-off point for the development of MACE with 94% sensitivity and 70% specificity. CONCLUSIONS: CHA2DS2-VASC-HSF score is proposed to be a simple bedside score that could be used for the prediction of the severity and complexity of CAD as well as a risk stratification tool for the development of MACE in NSTE ACS patients.

Background and study aims The prognosis for pancreatic cancer remains poor. Molecular diagnostics and customized therapies are becoming increasingly important in clinical routine. Patient-derived, predictive model systems such as organoids have the potential to substantially increase the depth of information from biopsy material by functional and molecular characterization. We compared the extent to which the use of fine-needle aspiration needles (FNA, 22G) or fine-needle biopsy needles (FNB, 22G) influences the generation of pancreatic cancer patient-derived organoids (PDOs) to establish endoscopic standards of organoid technology. Patients and methods Endoscopic ultrasound (EUS)-guided punctures by EUS-FNA and EUS-FNB of pancreatic masses highly suspicious for adenocarcinoma (detected by computed tomography and/or magnetic resonance imaging) were prospectively evaluated. Consecutive patients received EUS-FNA and EUS-FNB in a randomized order without the need to exchange the needle shaft (only the inner needle type (FNA/-B) was exchanged) between the passes. With each needle type, the specimens for histological analysis and for PDOs were obtained separately. Results Fifty patients were enrolled in the study. Histology revealed malignancy in 42 of 50 cases (84%). In total PDOs were generated from 17 patients (34%). Of these, nine were established by FNB only, two by FNA only, and six by both FNA and FNB. Histology revealed malignancy in 13 of 17 PDO cases (76%). In two histologically false-negative cases, PDOs could be established. Conclusions EUS-FNB was superior to EUS-FNA in terms of successful generation of PDOs, although it failed to show statistical significance.
RESUMEN
BACKGROUND: It is unknown whether the existence of severe bystander damage will affect left ventricular (LV) healing following primary percutaneous coronary intervention (PPCI). The aim of the present analysis was to follow LV recovery using 2D speckle tracking echocardiography (2-D STE) in cases with single versus multiple vessel disease with acute myocardial infarction (AMI) who underwent PPCI and to assess major adverse cardiovascular events (MACEs) within 3 months. PATIENTS AND METHODS: This work was conducted at Assiut University Heart Hospital. Of 1026 screened subjects with AMI needing PPCI and assessed for eligibility, only 89 cases fulfilled the inclusion criteria. They were classified into Group A: single vessel and Group B: multiple vessel (≥ 2 vessels) disease. Their data were obtained on admittance and after 90 days. RESULTS: In group A compared to group B, there was a statistically preferable value at baseline in the global longitudinal strain- Apical 2 chamber (GLS-A2C) (-12.05 ± 3.57 vs. -10.38 ± 3.92, P = 0.039). At follow-up, the improvement was in all 2-D STE variables, including GLS-long axis (GLS-LAX) (-13.09 ± 3.84 vs.-10.75 ± 3.96, P = 0.006), GLS- apical 4 chamber (GLS-A4C) (-13.23 ± 3.51 vs.-10.62 ± 4.08, P = 0.002), GLS-A2C (-13.85 ± 3.41 vs-10.93 ± 3.97, P < 0.001) and GLS- average (GLS-AVG, P = 0.001). There was a considerable negative correlation between the recovery of LV performance and the existence of multi-vessel lesions (P = 0.009). There was no variance between the groups regarding MACEs. CONCLUSIONS: Patients with single vessel lesions who underwent PPCI to the culprit lesion had better recovery of LV function than those with multi-vessel (≥ 2 vessels) lesions who underwent PPCI to the culprit lesion only. The presence of multivessel involvement was an independent risk factor for deterioration in GLS. TRIAL REGISTRATION: Registered in clinical trial, clinicalTrial.gov ID NCT04103008 (25/09/2019).

BACKGROUND: Development of esophageal strictures is common after the total laryngectomy of head and neck cancer patients. While endoscopic techniques like dilatation by balloon or Salvary bougies are well established, risk factors and pathophysiology for development of refractory strictures are less well understood. OBJECTIVE: To evaluate risk factors associated with occurrence and recurrence of total-laryngectomy-associated esophageal strictures in head and neck cancer patients. METHODS: We analyzed retrospectively a cohort of 170 head and neck squamous cell carcinoma patients, who underwent total laryngectomy between 2007 and 2017. The outcome measure was laryngectomy-associated proximal esophageal stricture needing an endoscopic dilatation by using a balloon or Savary dilators. RESULTS: Of the 170 patients in the cohort, 32 (18.8%) developed strictures. Mean time between surgery and first endoscopic intervention was 24.4 months. Significant predictive factors were age ≥ 65 (p=0.017), nodal status N> 1 (p=0.003), continued alcohol abuse after surgery (p=0.005) and diabetes mellitus (p=0.005). In a subgroup, 17 of 32 patients developed refractory strictures and needed more than three dilatations to relieve dysphagia. Postoperative mean (p=0.016) and maximum (p=0.015) C-reactive protein (CRP) were predictive for refractory strictures. CONCLUSION: Symptomatic strictures occurred in 18.8% of the cases. Age, nodal status N>1, continued alcohol abuse and diabetes mellitus were predictive factors. For refractory stenosis (>3 dilatations needed) mean and maximum postoperative CRP were predictive. This may indicate that systemic inflammatory response post-surgery is involved in the stricture formation process.

INTRODUCTION: The identification of risk factors for precursor lesions of colorectal cancer (CRC) holds great promise in the context of prevention. With this study, we aimed to identify patient characteristics associated with colorectal polyps (CPs) and polyp features of potential malignant progression. Furthermore, a potential association with gut microbiota in this context was investigated. METHODS: In this single-center study, a total of 162 patients with CPs and 91 control patients were included. Multiple variables including information on lifestyle, diet, serum parameters, and gut microbiota, analyzed by 16S-rRNA gene amplicon sequencing and functional imputations (Picrust2), were related to different aspects of CPs. RESULTS: We observed that elevated serum alkaline phosphatase (AP) levels were significantly associated with the presence of high-grade dysplastic polyps. This association was further seen for patients with CRC. Thereby, AP correlated with other parameters of liver function. We did not observe significant changes in the gut microbiota between patients with CP and their respective controls. However, a trend toward a lower alpha-diversity was seen in patients with CRC. Interestingly, AP was identified as a possible clinical effect modifier of stool sample beta diversity. DISCUSSION: We show for the first time an increased AP in premalignant CP. Furthermore, AP showed a significant influence on the microbial composition of the intestine. Relatively elevated liver enzymes, especially AP, may contribute to the detection of precancerous dysplastic or neoplastic changes in colorectal lesions. The association between elevated AP, premalignant CP, and the microbiome merits further study.

INTRODUCTION: Cold snare polypectomy (CSP) is a safe and effective procedure for small colorectal polyps ≤9 mm. There are only limited data regarding CSP of larger neoplastic lesions. This study evaluated the efficacy and safety of CSP for polyps between 10 and 15 mm in size. METHODS: In this prospective single-arm observational pilot study, patients with a least one polyp 10-15 mm were included. These polyps were preferably removed by CSP using a dedicated hybrid snare. The primary outcome was the histological complete resection rate (CRR) determined by pathologically negative margins of the specimen and no neoplastic tissue obtained from biopsies of the resection site margin. Secondary outcomes were en bloc resection rate, failure of CSP, and incidence of adverse events. RESULTS: A total of 61 neoplastic polyps were removed from 39 patients. Overall CRR was 80.3% (49/61). CSP was feasible in 78.7% (48/61) of polyps and the CRR in this group was 85.4% (41/48). When CSP failed (13/61; 21.3%), lesions were successfully resected by immediate HSP using the same snare with a CRR of 61.5% (8/13) in this group. One patient presented delayed hemorrhage after HSP of a polyp but successful hemostasis was achieved with two hemoclips. No other adverse events occurred. No recurrence was seen on follow-up colonoscopy in cases with incomplete resected polyps. CONCLUSION: CSP seems to be efficient and safe in removing colorectal polyps up to 15 mm. A hybrid snare seems to be particularly advantageous for these polyps as it allows immediate conversion to HSP if CSP might fail in larger polyps. This trial is registered at ClinicalTrials.gov (NCT04464837).

The runt-related transcription factor-1 (RUNX1) gene with its lncRNA RUNXOR are recently becoming a research focus in various diseases, specifically immune-related diseases as they are implicated in multiple pathways. Interestingly, their role in multiple sclerosis (MS) remains unstudied. The present study explored the role of RUNXOR/RUNX1 in the development and progression of MS and investigated their possible mechanism of action. We measured the serum expression levels of lncRNA RUNXOR, as well as RUNX1, microtubule associated protein 2 (MAP2), nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF) mRNAs in 30 healthy controls and 120 MS patients subdivided into 4 groups: 30 clinically isolated syndrome patients, 30 relapsing-remitting MS (RRMS) patients in relapse, 30 RRMS patients in remission and 30 secondary progressive MS patients. Additionally, we measured the serum protein levels of RUNX1, MAP2, NGF, BDNF and interleukin-10 (IL-10). All measured RNA expression levels were markedly downregulated and, consequently, the protein levels of RUNX1, MAP2, NGF, BDNF and IL-10 were significantly decreased in MS patients compared to healthy controls. Moreover, the levels of the measured parameters varied significantly within the MS groups. According to receiver-operating-characteristic (ROC) curve and logistic regression analyses, lncRNA RUNXOR, RUNX1 mRNA and its protein levels were predictors of disease progression, in addition to RUNX1 mRNA exhibiting a diagnostic potential. Altogether, this study suggests the implication of the RUNXOR-RUNX1 axis in MS development, progression, and increased MS-related disability, and highlights the potential utility of the studied parameters as promising diagnostic/prognostic biomarkers for MS.

BACKGROUND: Risk stratification and recommendation for surgery for intraductal papillary mucinous neoplasm (IPMN) are currently based on consensus guidelines. Risk stratification from presurgery histology is only potentially decisive owing to the low sensitivity of fine-needle aspiration. In this study, we developed and validated a deep learning-based method to distinguish between IPMN with low grade dysplasia and IPMN with high grade dysplasia/invasive carcinoma using endoscopic ultrasound (EUS) images. METHODS: For model training, we acquired a total of 3355 EUS images from 43 patients who underwent pancreatectomy from March 2015 to August 2021. All patients had histologically proven IPMN. We used transfer learning to fine-tune a convolutional neural network and to classify "low grade IPMN" from "high grade IPMN/invasive carcinoma." Our test set consisted of 1823 images from 27 patients, recruiting 11 patients retrospectively, 7 patients prospectively, and 9 patients externally. We compared our results with the prediction based on international consensus guidelines. RESULTS: Our approach could classify low grade from high grade/invasive carcinoma in the test set with an accuracy of 99.6â% (95â%CI 99.5â%-99.9â%). Our deep learning model achieved superior accuracy in prediction of the histological outcome compared with any individual guideline, which have accuracies between 51.8â% (95â%CI 31.9â%-71.3â%) and 70.4â% (95â%CI 49.8-86.2). CONCLUSION: This pilot study demonstrated that deep learning in IPMN-EUS images can predict the histological outcome with high accuracy.

Background and study aims Endoscopic ultrasound-guided gastroenterostomy (EUS-GE) with lumen-apposing metal stents (LAMS) appears to be a promising intervention in management of gastroduodenal out obstruction (GOO), particularly for patients for whom surgery is high risk or in a palliative setting. This study aimed to evaluate the technical feasibility, procedure-associated adverse events (AEs), and clinical outcome of direct "free hand" EUS-GE. Patients and methods This retrospective two-center study included patients who underwent direct "free hand" EUS-GE (April 2017 to March 2021) investigating technical success (correctly placed LAMS), clinical outcome (successful oral nutrition), and management of procedure-associated AEs. "Free hand" was defined as the use of the electrocautery enhanced stent delivery system alone without additional guidewire-assistance for EUS-GE creation. Results Forty-five patients (58â% women/42â% men; mean age 65 years) with malignant (nâ=â39), benign (nâ=â4) or unclear (nâ=â2) GOO underwent direct "free hand" EUS-GE. The technical success rate was 98â% (44/45). Of the patients, 95% (42/44) had less vomiting and increased ability to tolerate oral food intake after the intervention. In one patient, a second EUS-GE was necessary to achieve sufficient clinical improvement. Procedure-associated AEs were observed in 24â% (11/45) of cases including stent misplacement (nâ=â7), leakage (nâ=â1), development of a gastrojejunocolic fistula (nâ=â1), and bleeding (nâ=â2), which could be all managed endoscopically. Conclusions Direct EUS-GE has a favorable risk-benefit profile for patients with GOO, showing high technical success rates, manageable AEs, and rapid symptom relief.
RESUMEN
Background: Liver cancer is the deadliest malignancy among common tumors. It is the top cause of cancer-related deaths in Egypt, and it is characterized by increasing occurrence among the population. The objective of this study was to determine the outcome of pre-treatment of IQGAP1-shRNA on induced mouse hepatocellular carcinoma model and evaluate the potency of this IQGAP1-shRNA plasmid to recover hepatic cancer as a new tool of cancer therapy. Therefore, we will use RNA interference (RNAi) technology to silence IQGAP1 oncogene to completely recover the chemically induced models for hepatic cancer by designing short RNAi specific for IQGAP1 gene in HCC cells in vivo and construct new vectors suitable for this purpose. We assigned mice into three groups: the first negative control group (NC) was injected with saline, the second control group was injected with shRNA (shNC), the third positive control group was injected with diethylnitrosamine (DENAA), and the fourth group was treated with the IQGAP1-shRNA prior to its exposure to DENA. Results: Our results revealed that the treated group with IQGAP1-shRNA with DENA developed very few cases of hepatic cancer when compared with the positive control group. The positive control group exhibited significant increases in the liver function level as well as a decrease in serum albumin levels when compared to both the treated and the negative control groups. The altered levels of the serum α-fetoprotein as well as of the tumor necrosis factor-alpha, and interleukin-4 in DENA-treated mice were significantly ameliorated by IQGAP1-shRNA administration. Flow cytometer analyses have indicated that the silencing of IQGAP1 cannot significantly modulate DENA-induced apoptosis in the circulating blood cells. Moreover, the elevated mRNA expression levels of IQGAP1, IQGAP3, KRas, HRas, interleukin-8, nuclear factor kappa B, caspase-3, caspase-9 and Bcl-2, were significantly decreased by the IQGAP1-shRNA treatment. However, the IQGAP2, DR4, DR5, p53 and BAX genes were found to be significantly up-regulated post-therapy. In agreement with these findings, IQGAP1-shRNA was able to modulate the DENA-induced histological changes in the mice liver which were represented by severe necrosis and hydropic degenerative changes. Conclusion: Our study revealed that IQGAP1-shRNA was able to preserve hepatocyte integrity and the liver histological architecture through the regulation of the expression of IQGAPs, Ras, TRAILs and IL-8 receptors, as well as of pro-apoptotic and anti-apoptotic genes. Therefore, the silencing of IQGAP1 could be part of a promising therapeutic strategy against hepatic cancer.
RESUMEN
BACKGROUND: Depression is a common problem in women in childbearing years due to burdens of motherhood and building a family. Few studies estimate the prevalence of antepartum depression compared to those in the postpartum period. AIM: To estimate the prevalence and the severities of peripartum depression and major depressive disorder and their predictors. METHODS: This is a longitudinal observation study. It included 200 women scoring ≥ 13 with the Edinburgh Postpartum Depression Scale, indicating presence of symptoms of depression. They had a gestational age of ≥ 6 wk and did follow-ups until the 10th week to 12th weeks postpartum. Information of women's reactions to life circumstances and stressors during the current pregnancy were gathered from answers to questions of the designed unstructured clinical questionnaire. Severities of depression, anxiety, and parenting stress were determined by the Beck Depre-ssion Inventory, State-Trait Anxiety Inventory for Adults, and Parenting Stress Index-Short Form, respectively. Psychiatric interviewing was done to confirm the diagnosis of major depression. Measuring the levels of triiodothronine (T3), thyroxine (T4), and thyroid stimulating hormone (TSH) was done in both antepartum and postpartum periods. RESULTS: Out of 968 (mean age = 27.35 ± 6.42 years), 20.66% (n = 200) of the patients had clinically significant symptoms of depression and 7.44% had major depression. Previous premenstrual dysphoria, post-abortive depression, and depression unrelated to pregnancy and were reported in 43%, 8%, and 4.5% of the patients, respectively. Psychosocial stressors were reported in 15.5% of the patients. Antepartum anxiety and parenting stress were reported in 90.5% and 65% of the patients, respectively. Postpartum T3, T4, and TSH levels did not significantly differ from reference values. Regression analysis showed that anxiety trait was a predictor for antepartum (standardized regression coefficients = 0.514, t = 8.507, P = 0.001) and postpartum (standardized regression coefficients = 0.573, t = 0.040, P = 0.041) depression. Antepartum depression (standardized regression coefficients = -0.086, t = -2.750, P = 0.007), and parenting stress (standardized regression coefficients = 0.080, t = 14.34, P = 0.0001) were also predictors for postpartum depression. CONCLUSION: Results showed that 20.66% of the patients had clinically significant symptoms of depression and 7.44% had major depression. Anxiety was a predictor for antepartum and postpartum depression. Antepartum depression and parenting stress were also predictors for postpartum depression.
RESUMEN
Coastal civil infrastructure is vulnerable to the effects of climate change. Hurricane storm surge and coastal flooding can cause significant hydrostatic and hydrodynamic loads on structures while saltwater intrusion (SWI) may lead to deterioration of foundations. The effects of saltwater intrusion due to Sea Level Rise (SLR) on the foundations of buildings and other civil infrastructure is poorly understood. Such damages may not be detected in a timely fashion nor be insured, leading to significant and unanticipated expenses for building owners. In this study, we evaluate the impact of SWI due to various SLR scenarios on the corrosion of reinforcement in foundations of nearly 137,000 residential buildings in low-lying areas surrounding Mobile Bay, AL. We find that the potential for costly damage is significant. Under an extreme SLR scenario, the annual expected repair costs for the foundations of the studied homes may reach as much as US$90 million by 2100.

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for coronavirus disease-2019 (COVID-19). Elderly subjects, obese, and patients with chronic illnesses, are the most affected group. HDL has pleiotropic physiological functions that are affected with alteration(s) in its structure. Main text: Inflammation whether septic, immune, or other affects HDL structure and function. COVID-19 is associated with systemic immune-inflammation due to cytokine surge. Viral interaction with erythrocytes and hemoglobin-related compounds (may cause anemia and hypoxia) and other factors may affect HDL function. Trials have been conducted to resume HDL functions using peptide preparation, nutritional, and herbal elements. Conclusions: In this review article, I'll discuss the use of reconstituted HDL (rHDL), Apo-A1 mimetic peptide D-4F, ω-3 polyunsaturated fatty acids, and the powdered roots and/or extract of Saussurea lappa (costus) to avoid comorbidity and mortality of COVID-19 in patients with chronic illness or elderly-age mortality.
RESUMEN
Background: Acute myeloid leukemia (AML) is of heterogeneous pathogenesis and caused by alterations of multiple genes. CircRNAs act as oncogenes or tumor suppressors in numerous tumors and could be novel diagnostic and prognostic biomarkers. Few studies had incorporated circRNAs in AML. Aim of the Work: Assessment of circANXA2, circ0075001, and circFBXW7 gene expressions in AML patients. Evaluation of their relations with clinical, cytogenetic, and overall survival outcome to emphasize their diagnostic role and prognostic impact. Methods: This study was carried out on 120 subjects (66 AML patients and 54 controls). All subjects were subjected to gene expressions assay for circANXA2, circ0075001, circFBXW7 by quantitative real-time polymerase chain reaction. Results: Prominent overexpression of circANAX2 and circ0075001 in patients than control (P < 0.001), whereas circFBXW7 was markedly downregulated in patients than in control (P < 0.001). Moreover, circANXA2 with AUC 0.824, P <0.001, had a sensitivity of 74.24%, specificity 88.89% whereas circ0075001 with AUC 0.855, P < 0.001, had the highest sensitivity of 83.33% and specificity 79.63%, and circFBXW7 with AUC 0.826, P < 0.001, had a sensitivity of 75.76% and specificity 74.07% in the distinction of AML patients from controls. Additionally, we find out that high expression of circANXA2 and circ0075001 correlated significantly with splenomegaly, hepatomegaly, less differentiated FAB subtypes (M5, M7), short overall survival, and had an adverse cytogenetic pattern. Conclusion: CircANXA2, circ0075001, and circFBXW7 gene expressions could serve as potential diagnostic biomarkers for AML disease. Moreover, CircANXA2 and circ0075001 exert poor prognostic effects on AML patients.
RESUMEN
BACKGROUND AND GOALS: Risk stratification for the need for therapeutic endoscopy and prediction of mortality in patients with upper gastrointestinal bleeding (UGIB) can be assessed by several scores. However, current scores are not validated for variceal bleeding and Intensive Care Unit (ICU) patients. The aim of this study was to evaluate potential parameters for the prediction of UGIB and patient outcomes. PATIENTS AND STUDY METHODS: In this monocenter retrospective observational study, data from all esophagogastroduodenoscopies (EGD) between November 2014 and February 2020 with suspected hemorrhage in our ICU were evaluated. RESULTS: Out of 345 included EGD, 42.3% of UGIB was diagnosed. 51.9% needed endoscopic intervention. Overall, 52.3% of included patients with UGIB died. Logistic regression showed that preceding variceal or non-variceal UGIB (p < .001), serum lactate (p = .001), heart rate (HR) (p = .005), and blood transfusions (p = .001) were significant predictors of UGIB. Previous UGIB (p < .001), male sex (p = .015), known varices (p < .001), serum albumin (p = .19) and use of catecholamines (p = .040) were significant predictors for the need of endoscopic intervention. Higher mortality was significantly associated with the usage of steroids (p < .001), malignant preconditions (p = .021), serum albumin (p = .020) and prolonged PTT (partial thromboplastin time) (p = .001). CONCLUSIONS: We were able to identify additional parameters that had previously not been included in existing scores to predict the risk of UGIB, the need for therapeutic endoscopy and mortality in ICU patients. Therefore, an extension of these scores is necessary. Further validation of identified parameters in multicenter trials is needed to improve risk scores for ICU patients.

The role of emergency shockwave lithotripsy (SWL) in persistent pain control in patients with ureteral stones is not well established. The aim of this study is to evaluate efficacy as well as the predicting variables for successful early SWL patients with symptomatic ureteral stones. Eighty-six patients with a persistent renal colic secondary to single ureteral stone (6-12 mm) were prospectively enrolled in this study. SWL was performed within 24 h of the onset of flank pain. Pain control and stone-free rate after emergency SWL session were 58.1% and 44.2%, respectively. Seven patients required post-SWL ureteroscopy and ureteral stent placement for uncontrolled pain. The overall 3-month stone-free rate after SWL monotherapy was 83.7%. On multivariate analysis, predictors for pain relief after emergency SWL were lower Hounsfield (HU) stone density, mild hydronephrosis (HN) at presentation and presentation during the first colic episode. Lower HU stone density was the single predictor of successful stone clearance after single emergency SWL session on multivariate analysis. In conclusion, early SWL is feasible and effective in management of ureteral stones presented by renal colic with low HU.

BACKGROUND: Malignant tumors of the esophagus are the sixth leading cause of cancer-related deaths worldwide. Postoperative leakage of the esophago-gastrostomy leads to mediastinal sepsis, which is still associated with a high morbidity and mortality rate. The aim of this study was to describe the endoscopic view of the different severity grades of an anastomotic leakage. METHODS: Patients Between June 2016 and September 2018, 144 patients were operated upon in the Department of Surgery, University of Munich, Germany. Among these patients, 34 (23.6%) presented with a leakage of the anastomosis. Endoscopy In this retrospective analysis, the focus is to describe different patterns of leakage of the anastomosis. RESULTS: We studied 34 patients in whom post-esophagectomy leakage of the anastomosis was detected and treated with an endoluminal vacuum sponge system. The leakage healed in 26 of 29 patients (success rate 89.7%). With the increasing severity of leakage, the treatment time and the in-hospital mortality correspondingly increased. Furthermore, the incidence of the development of a fistula to the tracheobronchial system increased with higher grades of leakage. CONCLUSIONS: Exact descriptions of leakage are necessary to compare the cases and to prove post-treatment improvement. This is, to our knowledge, the first publication to present a leakage grading score in patients after esophagectomy including reconstruction with a gastric tube. This new grading system needs to be tested in further analyses, with a special focus on prospective analysis.

OBJECTIVE: To evaluate the effect of performing laparoscopic ovarian drilling [LOD] before proceeding to in vitro fertilization [IVF] or intracytoplasmic sperm injection [ICSI] on the cycle outcomes in polycystic ovarian syndrome [PCOS] patients with high antimullerian hormone [AMH] levels. STUDY DESIGN: A retrospective case-control study. PATIENTS AND METHODS: The study was conducted in the Fertility Care Unit in our University Hospital. The participants of the study were PCOS women with high serum AMH levels [≥ 7 ng/ml] who were subjected to IVF/ICSI. Women who underwent LOD in the preceding 3 months before IVF/ICSI [study group; n = 76] were compared with a control group of women who did not undergo LOD [control group; n = 71]. RESULTS: Total gonadotropin consumption and the number of stimulation days were significantly lower with LOD [P = 0.026 and 0.010, respectively]. Oocyte maturity rate was significantly higher with LOD [P = 0.028]. The incidence of severe OHSS was significantly lower with LOD [P = 0.026]. No significant difference between both groups in the pregnancy and implantation rates. CONCLUSION: The LOD before IVF/ICSI in PCOS patients with high AMH [≥ 7 ng/ml] has the benefits of reduction in gonadotropins consumption and stimulation days with an increase in the percentage of collected mature oocytes and decrease in the incidence of severe OHSS; however, it seems not to improve the pregnancy and implantation rates.

OBJECTIVE: We aimed to investigate the signalling crosstalk of TNF-related apoptosis-inducing ligand, TRAIL death receptors, tumour protein p53, and programmed cell death (PDCD5) with IQGAPs. Also, we targeted the crosstalk between IQGAPs genes with decoy receptors, nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB), and interleukins -8 (IL-8) and its receptor genes in a designed model of hepatocellular carcinoma induced in male Balb/c mice. METHODS: The presence of HCC was confirmed by histological and morphological alterations. In parallel to the incidence of hepatic cancer, we found lung, heart, and kidney cancer after treatment with DEN. RESULTS: Our results show that the expression of mRNA of IQGAP1, TRAIL decoy receptors, NF-κB, and IL-8 genes was elevated in hepatocellular carcinoma, as compared to normal liver tissue, while their expression was further up-regulated by increasing the dose of diethylnitrosamine. The expression of IQGAP2, TRAIL death receptors, p53, and PDCD5 was significantly down-regulated in HCC (pË0.05). For confirmation of gene expression, protein levels of both IQGAP1 and P53 were measured by western blot analysis, which showed that diethylnitrosamine enhanced protein expression of IQGAP1 and diminished that of p53. CONCLUSION: IQGAPs have a direct signaling relationship with p53, IL-8, and TRAIL family. This interaction is recognized as a key signalling pathway for hepatocellular carcinogenesis.
