Main-Duct Intraductal Papillary Mucinous Neoplasm Complicated by a Pancreaticogastric Fistula and a Pancreaticocholedocal Fistula.

Intraductal papillary mucinous neoplasms (IPMNs) of the pancreas are a spectrum of benign to malignant epithelial neoplasms that are characterized by papillary proliferation, duct dilation, and cyst formation. A rare complication of IPMNs is fistula formation into adjacent organs such as the duodenum, biliary system, and stomach. Here, we report a case of IPMN with a pancreaticobiliary fistula and pancreaticogastric fistula. An 84-year-old woman with early Alzheimer's disease was diagnosed with IPMN of the pancreas. She deferred surgery given her age and remained asymptomatic for five years until presenting with cholangitis. She had been further evaluated and was found to have a pancreaticobiliary fistula, which was treated with biliary stent placement. Her subsequent admission involved the formation of a new pancreaticogastric fistula. This case highlights potential complications of excess mucin production from unresected IPMNs and demonstrates a guarded prognosis in elderly patients.

Comparison of no stent fixation, endoscopic suturing, and a novel over-the-scope clip for stent fixation in preventing migration of fully covered self-expanding metal stents: a retrospective comparative study (with video).

BACKGROUND AND AIMS: Endoscopic suturing and over-the-scope clips (OTSCs) are used to prevent migration of fully covered self-expandable metal stents (FCSEMSs). Recently, a dedicated OTSC was developed for securing FCSEMSs. Our primary aim was to compare the frequency of stent migration without stent fixation versus fixation with suturing or OTSCs, and out secondary aims were to compare clinical success, procedure duration, and adverse events. METHODS: A retrospective cohort study evaluated the outcome of stent placement throughout the entire GI tract from 2013 to 2021. Stent migration was determined as stent displacement ≥2 cm endoscopically or radiographically. Clinical success was defined as resolution of indication at follow-up. RESULTS: Four hundred thirty-three procedures were performed, 239 (55%) without fixation, 140 (32%) with suturing, and 54 (12%) with OTSCs. Stent migration rates were 62% without fixation, 57% with suturing, and 35% with OTSCs (P = .013). The median time to stent migration was 3 weeks without fixation, 5 weeks with suturing, and 6 weeks with OTSCs (P = .023). The clinical success rate was 43%. The median procedure time for OTSCs was shorter compared with suturing (42 vs 68 minutes, P = .002). Adverse event rates trended toward being lowest with OTSCs at 9% compared with 21% without fixation and 18% with suturing (P > .05). CONCLUSIONS: OTSCs for stent fixation were found to have significantly lower migration rates compared with no fixation and suturing. Moreover, OTSCs were associated with decreased overall procedure time and total costs per procedure while trending to be associated with fewer adverse events.

Risk Factors for Posttransplantation Mortality in Recipients With Grade 3 Acute-on-Chronic Liver Failure: Analysis of a North American Consortium.

Although liver transplantation (LT) yields survival benefit for patients with acute-on-chronic liver failure grade 3 (ACLF-3), knowledge gaps remain regarding risk factors for post-LT mortality. We retrospectively reviewed data from 10 centers in the United States and Canada for patients transplanted between 2018 and 2019 and who required care in the intensive care unit prior to LT. ACLF was identified using the European Association for the Study of the Liver-Chronic Liver Failure (EASL-CLIF) criteria. A total of 318 patients were studied, of whom 106 (33.3%) had no ACLF, 61 (19.1%) had ACLF-1, 74 (23.2%) had ACLF-2, and 77 (24.2%) had ACLF-3 at transplantation. Survival probability 1 year after LT was significantly higher in patients without ACLF (94.3%) compared with patients with ACLF (87.3%; P = 0.02), but similar between ACLF-1 (88.5%), ACLF-2 (87.8%), and ACLF-3 (85.7%; P = 0.26). Recipients with ACLF-3 and circulatory failure (n = 29) had similar 1-year post-LT survival (82.3%) compared with patients with ACLF-3 without circulatory failure (89.6%; P = 0.32), including those requiring multiple vasopressors. For patients transplanted with ACLF-3 including respiratory failure (n = 20), there was a trend toward significantly lower post-LT survival (P =  0.07) among those with respiratory failure (74.1%) compared with those without (91.0%). The presence of portal vein thrombosis (PVT) at LT for patients with ACLF-3 (n = 15), however, yielded significantly lower survival (91.9% versus 57.1%; P < 0.001). Multivariable logistic regression analysis revealed that PVT was significantly associated with post-LT mortality within 1 year (odds ratio, 7.3; 95% confidence interval, 1.9-28.3). No correlation was found between survival after LT and the location or extent of PVT, presence of transjugular intrahepatic portosystemic shunt, or anticoagulation. LT in patients with ACLF-3 requiring vasopressors yields excellent 1-year survival. LT should be approached cautiously among candidates with ACLF-3 and PVT.

Invasive Colloid Carcinoma and the role of Ki-67 and HER2 - Two case reports.

Mucinous carcinoma (also termed colloid carcinoma) of the breast accounts for 1%-6% of all breast cancer and is considered to have a good relative prognosis. The most common mammographic appearance of pure mucinous carcinoma is a high-density mass with circumscribed margins and on sonographic examination an isoechoic round mass with circumscribed margins. We report 2 cases of invasive mucinous carcinoma, in which one patient showed an intermediate recurrence risk based on Ki-67 and human epidermal growth factor receptor 2 negativity, while the other showed a low Ki-67 recurrence risk and human epidermal growth factor receptor 2 positive. We also review the literature on Ki-67 and human epidermal growth factor receptor 2 and explore the roles of these molecular markers in mucinous carcinomas.

Long-term telemental health prevention interventions for youth: A rapid review.

INTRODUCTION: This rapid review identifies and summarizes the effectiveness of preventative telemental health interventions. It investigates studies conducted between 2010 and 2016 that improve mood and anxiety with long-term follow-up. METHODS: A literature search of three major databases was performed by four reviewers. After citation tracing, 3604 studies were discovered, and twenty of these met the inclusion criteria. Data from the papers were abstracted, assessed for quality, and effect sizes were calculated. RESULTS: Salient information was discussed using the Behavioural Vaccine Model of mental illness prevention. This included key concepts such as efficacy, duration of benefits, sociocultural relevance, professional guidance, peer-to-peer support, adherence, delivery and safety. CONCLUSION: This review suggests there are clear prolonged benefits to using technology in youth mental illness prevention. Although this is a rapidly growing area of investigation in countries around the globe, there is still a dearth of research with long-term follow-up. Future studies should aim to boost engagement by increasing motivational guidance in order to recruit at-risk youth of all demographics into these promising intervention programs.
