In an analysis of a large cohort of subjects with IBD, we found a significant association between symptoms of depression or anxiety and clinical recurrence. Patients with IBD should therefore be screened for clinically relevant levels of depression and anxiety and referred to psychologists or psychiatrists for further evaluation and treatment.
BackgroundThe distinction between right-sided and left-sided colon cancer has recently received considerable attention due to differences regarding underlying genetic mutations. There is an ongoing debate if right- versus left-sided tumor location itself represents an independent prognostic factor. We aimed to investigate this question by using propensity score matching.MethodsPatients with resected, stage I - III colon cancer were identified from the Surveillance, Epidemiology, and End Results (SEER) database (2004–2012). Both univariable and multivariable Cox regression as well as propensity score matching were used.ResultsOverall, 91,416 patients (51,937 [56.8 %] with right-sided, 39,479 [43.2 %] with left-sided colon cancer; median follow-up 38 months) were eligible. In univariable analysis, patients with right-sided cancer had worse overall (hazard ratio [HR] = 1.32, 95 % CI:1.29–1.36, P < 0.001) and cancer-specific survival (HR = 1.26, 95 % CI:1.21–1.30, P < 0.001) compared to patients with left-sided cancer. After propensity score matching, the prognosis of right-sided carcinomas was better regarding overall (HR = 0.92, 95 % CI: 0.89 − 0.94, P < 0.001) and cancer-specific survival (HR = 0.90, 95 % CI:0.87 − 0.93, P < 0.001). In stage I and II, the prognosis of right-sided cancer was better for overall (HR = 0.89, 95 % CI:0.84–0.94 and HR = 0.85, 95 % CI:0.81–0.89) and cancer-specific survival (HR = 0.71, 95 % CI:0.64 − 0.79 and HR = 0.75, 95 % CI:0.70–0.80). Right- and left-sided colon cancer had a similar prognosis for stage III (overall: HR = 0.99, 95 % CI:0.95–1.03 and cancer-specific: HR = 1.04, 95 % CI:0.99–1.09).ConclusionsThis population-based analysis on stage I - III colon cancer provides evidence that the prognosis of localized right-sided colon cancer is better compared to left-sided colon cancer. This questions the paradigm from previous research claiming a worse survival in right-sided colon cancer patients.
Hemospray (Cook Medical, Winston-Salem, North Carolina, USA) is a hemostatic agent recently introduced for the management of upper gastrointestinal bleeding (GIB). To date, there is little experience with this fairly new hemostatic tool. The aim of this case series was to reflect the use and effectiveness of Hemospray as a treatment option in GIB in everyday clinical practice at two tertiary referral centers. Consecutive patients (n = 16) with active GIB of various origins were treated with Hemospray. Abstract:Hemospray (Cook Medical, Winston-Salem, North Carolina, USA) is a hemostatic agent recently introduced for the management of upper gastrointestinal bleeding (GIB). To date, small experience exists with this fairly new hemostatic tool. The aim of this case series was to reflect the use and effectiveness of Hemospray as treatment option in GIB in all-day clinical practise. Sixteen consecutive patients with active GIB of various origins were treated with Hemospray. The rate of successful initial hemostasis was 93.75% (as salvage therapy success rate 92.85%; as monotherapy success rate 100%). The rebleeding rate within 7 days was 12.5%.Only one patient failed also interventional radiology and had to undergo surgery as salvage therapy.Effectiveness of Hemospray in the management of GIB in various clinical situations is promising. Future multicenter randomized prospective trials for clearly defined bleeding situations are needed to increase the generalizability of case series.
Background and AimsLow-quality bowel preparation reduces efficacy of colonoscopy. We aimed to summarize effects of bowel preparation on detection of adenomas, advanced adenomas and colorectal cancer.MethodsA systematic literature search was performed regarding detection of colonic lesions after normal and low-quality bowel preparation. Reported bowel preparation quality was transformed to the Aronchick scale with its qualities “excellent”, “good”, “fair”, “poor”, and “insufficient” or “optimal” (good/excellent), “suboptimal” (fair/poor/insufficient), “adequate” (good/excellent/fair) and “inadequate” (poor/insufficient). We identified two types of studies: i) Comparative studies, directly comparing lesion detection according to bowel preparation quality, and ii) repeat colonoscopy studies, reporting results of a second colonoscopy after previous low-quality preparation.ResultsThe detection of early adenomas was reduced with inadequate vs. adequate bowel preparation (Odds Ratio (OR) 0.53, CI: 0.46–0.62, p<0.001). The advanced adenomas were affected less in comparison (0.74, CI: 0.62–0.87, p<0.001). The large number of subjects considered in the present meta-analysis resulted in smaller confidence intervals compared to earlier studies. Classifying the bowel-preparation quality as suboptimal vs. optimal led to the same qualitative conclusion (OR: 0.81, CI: 0.74–0.89, p<0.001 for early adenomas, OR: 0.94, CI: 0.87–1.01, n.s. for advanced adenomas). Bowel preparation was equally important for right-sided/ flat/ serrated vs. other lesions in most observational studies but more relevant in some repeat colonoscopy studies; data regarding carcinoma detection were insufficient.ConclusionInadequate bowel preparation affects detection of early colonic lesions stronger than advanced lesions.
Von Hippel-Lindau (VHL) disease is an autosomal dominantly inherited tumour predisposition syndrome with an incidence of 1:36,000 newborns, the estimated prevalence in Europe is about 1-9/100,000. It is associated with an increased risk of developing various benign and malignant tumours, thus affecting multiple organs at different time points in the life of a patient. Disease severity and diversity as well as age at first symptoms vary considerably, and diagnostic delay due to failure of recognition is a relevant issue. The identification of a disease-causing VHL germline mutation subsequently allows family members at risk to undergo predictive genetic testing after genetic counselling. Clinical management of patients and families should optimally be offered as an interdisciplinary approach. Prophylactic screening programs are a cornerstone of care, and have markedly improved median overall survival of affected patients. The aim of this review is to give an overview of the heterogeneous manifestations of the VHL syndrome and to highlight the diagnostic and therapeutic challenges characteristic for this orphan disease. A comprehensive update of the underlying genetic and molecular principles is additionally provided. We also describe how the St. Gallen VHL multidisciplinary group is organised as an example of interdisciplinary cooperation in a tertiary hospital in Switzerland.
Colonoscopy withdrawal time in unmonitored gastroenterologists is shorter than recommended and increases with awareness of monitoring. ADR significantly increases when gastroenterologists are aware of being monitored. Implementation of systematic monitoring, and analysis of withdrawal time and ADR for each endoscopist may help to increase the ADR.
L-Asparaginase is commonly used in combination chemotherapy of both pediatric and adult acute lymphoblastic leukemia. The majority of adverse effects are hypersensitivity reactions, but serious liver injury may also occur. It has been shown that treatment with L-asparaginase can be associated mainly with macrovesicular hepatic steatosis which may be accompanied by alterations in lipid metabolism. So far, the mechanism for liver injury associated with L-asparaginase is not known. We report here an adult patient who developed mixed liver injury and predominantly microvesicular hepatic steatosis while being treated with L-asparaginase for acute lymphoblastic leukemia. The patient developed liver failure and died due to multiorgan failure. Both impaired liver mitochondrial function and alterations in very-low-density lipoprotein metabolism and secretion are discussed as two possible mechanisms explaining the findings observed in this patient.
Background: Treatment of inflammatory bowel diseases (IBD) has tremendously improved during the last 20 years; however, a substantial fraction of patients does not respond to available therapies or lose response, and new strategies are needed. Summary: Two pharmacological principles have been successfully used for IBD treatment: inhibition of cellular signaling and interference with leukocyte trafficking. Besides tumor necrosis factor, interleukin (IL)-23 is a promising drug target, and antibodies for the combined inhibition of IL-23 and IL-12 (ustekinumab and briakinumab) or selective IL-23 inhibition (brazikumab, risankizumab, and mirikizumab) seem to be effective in Crohn's disease (CD) with emerging evidence also for ulcerative colitis (UC). Janus kinase (JAK) mediates intracellular signaling of a large number of cytokines. Tofacitinib is the first JAK inhibitor approved for
