Acute Pancreatitis Revealing a Diagnosis of Diffuse Large B-Cell Lymphoma.

Acute pancreatitis is a common gastroenterological condition that can occur due to several causes. While not required for diagnosis, imaging is often performed and may reveal unexpected findings such as pancreatic masses. Malignancies such as lymphoma are uncommon causes of acute pancreatitis, especially as the initial presentation of malignancy. We present a case of a young patient with acute pancreatitis caused by diffuse large B-cell lymphoma with extranodal disease secondarily involving the pancreas. Our case highlights the importance of keeping a broad differential for acute pancreatitis and considering rare etiologies such as pancreatic lymphoma in patients without another obvious culprit.

Daydreaming and grandiose delusions: development of the Qualities of Daydreaming Scale.

BACKGROUND: Daydreaming may contribute to the maintenance of grandiose delusions. Repeated, pleasant and vivid daydreams about the content of grandiose delusions may keep the ideas in mind, elaborate the details, and increase the degree of conviction in the delusion. Pleasant daydreams more generally could contribute to elevated mood, which may influence the delusion content. AIMS: We sought to develop a brief questionnaire, suitable for research and clinical practice, to assess daydreaming and test potential associations with grandiosity. METHOD: 798 patients with psychosis (375 with grandiose delusions) and 4518 non-clinical adults (1788 with high grandiosity) were recruited. Participants completed a daydreaming item pool and measures of grandiosity, time spent thinking about the grandiose belief, and grandiose belief conviction. Factor analysis was used to derive the Qualities of Daydreaming Scale (QuOD) and associations were tested using pairwise correlations and structural equation modelling. RESULTS: The questionnaire had three factors: realism, pleasantness, and frequency of daydreams. The measure was invariant across clinical and non-clinical groups. Internal consistency was good (alpha-ordinals: realism=0.86, pleasantness=0.93, frequency=0.82) as was test-retest reliability (intra-class coefficient=0.75). Daydreaming scores were higher in patients with grandiose delusions than in patients without grandiose delusions or in the non-clinical group. Daydreaming was significantly associated with grandiosity, time spent thinking about the grandiose delusion, and grandiose delusion conviction, explaining 19.1, 7.7 and 5.2% of the variance in the clinical group data, respectively. Similar associations were found in the non-clinical group. CONCLUSIONS: The process of daydreaming may be one target in psychological interventions for grandiose delusions.

TACTICS VR Stroke Telehealth Virtual Reality Training for Health Care Professionals Involved in Stroke Management at Telestroke Spoke Hospitals: Module Design and Implementation Study.

BACKGROUND: Stroke management in rural areas is more variable and there is less access to reperfusion therapies, when compared with metropolitan areas. Delays in treatment contribute to worse patient outcomes. To improve stroke management in rural areas, health districts are implementing telestroke networks. The New South Wales Telestroke Service provides neurologist-led telehealth to 23 rural spoke hospitals aiming to improve treatment delivery and patient outcomes. The training of clinical staff was identified as a critical aspect for the successful implementation of this service. Virtual reality (VR) training has not previously been used in this context. OBJECTIVE: We sought to develop an evidence-based VR training module specifically tailored for stroke telehealth. During implementation, we aimed to assess the feasibility of workplace deployment and collected feedback from spoke hospital staff involved in stroke management on training acceptability and usability as well as perceived training impact. METHODS: The TACTICS VR Stroke Telehealth application was developed with subject matter experts. During implementation, both quantitative and qualitative data were documented, including VR use and survey feedback. VR hardware was deployed to 23 rural hospitals, and use data were captured via automated Wi-Fi transfer. At 7 hospitals in a single local health district, staff using TACTICS VR were invited to complete surveys before and after training. RESULTS: TACTICS VR Stroke Telehealth was deployed to rural New South Wales hospitals starting on April 14, 2021. Through August 20, 2023, a total of 177 VR sessions were completed. Survey respondents (n=20) indicated a high level of acceptability, usability, and perceived training impact (eg, accuracy and knowledge transfer; mean scores 3.8-4.4; 5=strongly agree). Furthermore, respondents agreed that TACTICS VR increased confidence (13/18, 72%), improved understanding (16/18, 89%), and improved awareness (17/18, 94%) regarding stroke telehealth. A comparison of matched pre- and posttraining responses revealed that training improved the understanding of telehealth workflow practices (after training: mean 4.2, SD 0.6; before training: mean 3.2, SD 0.9; P<.001), knowledge on accessing stroke telehealth (mean 4.1, SD 0.6 vs mean 3.1, SD 1.0; P=.001), the awareness of stroke telehealth (mean 4.1, SD 0.6 vs mean 3.4, SD 0.9; P=.03), ability to optimally communicate with colleagues (mean 4.2, SD 0.6 vs mean 3.7, SD 0.9; P=.02), and ability to make improvements (mean 4.0, SD 0.6 vs mean 3.5, SD 0.9; P=.03). Remote training and deployment were feasible, and limited issues were identified, although uptake varied widely (0-66 sessions/site). CONCLUSIONS: TACTICS VR Stroke Telehealth is a new VR application specifically tailored for stroke telehealth workflow training at spoke hospitals. Training was considered acceptable, usable, and useful and had positive perceived training impacts in a real-world clinical implementation context. Additional work is required to optimize training uptake and integrate training into existing education pathways.

Outcomes of Cold Snare Endoscopic Mucosal Resection of Nonampullary Duodenal Adenomas ≥1 cm: A Multicenter Study.

BACKGROUND AND AIMS: Endoscopic mucosal resection (EMR) with use of electrocautery (conventional EMR) has historically been used to remove large duodenal adenomas, however, use of electrocautery can predispose to adverse events including delayed bleeding and perforation. Cold snare EMR (cs-EMR) has been shown to be safe and effective for removal of colon polyps, but data regarding its use in the duodenum is limited. The aim of this study is to evaluate the efficacy and safety of cs-EMR for nonampullary duodenal adenomas ≥1 cm. METHODS: This was a multicenter retrospective study of patients with nonampullary duodenal adenomas ≥1 cm who underwent cs-EMR between October 2014 and May 2023. Patients who received any form of thermal therapy were excluded. Primary outcomes were technical success and rate of recurrent adenoma. Secondary outcomes were adverse events and predictors of recurrence. RESULTS: A total of 125 patients underwent resection of 127 nonampullary duodenal adenomas with cs-EMR. Follow up data was available in 89 cases (70.1%). The recurrent adenoma rate was 31.5% (n=28). Adverse events occurred in 3.9% (n=5) with four cases of immediate bleeding (3.1%) and one case of delayed bleeding (0.8%). There were no cases of perforation. The presence of high-grade dysplasia was found to be an independent predictor of recurrence (OR: 10.9 [95% CI: 1.1-102.1], p=0.036). CONCLUSION: This retrospective multicenter study demonstrates that cs-EMR for nonampullary duodenal adenomas is safe and technically feasible with an acceptable recurrence rate. Future prospective studies are needed to directly compare outcomes of cs-EMR with conventional and underwater EMR.

Primary Pancreatic Liposarcoma: An Unexpected Cause of a Pancreatic Mass.

Liposarcoma is the most common type of soft-tissue sarcoma and typically occurs in the extremities or retroperitoneum. Primary liposarcoma of the pancreas is exceedingly rare, with only 10 cases reported since 1979. We present a patient who was incidentally discovered to have a pancreatic mass on imaging, which was ultimately diagnosed as dedifferentiated pancreatic liposarcoma. We review the clinical and histologic features of pancreatic liposarcoma in this case and in the 10 previously reported cases to increase awareness and knowledge of this rare disease.

Cold snare endoscopic mucosal resection for colon polyps: a systematic review and meta-analysis.

BACKGROUND: Cold snare endoscopic mucosal resection (CS-EMR) can reduce the risks associated with electrocautery during colon polyp resection. Data on efficacy are variable. This systematic review and meta-analysis aimed to estimate the pooled efficacy and safety rates of CS-EMR. METHODS: We conducted a comprehensive literature search of multiple databases, from inception to March 2023, for studies addressing outcomes of CS-EMR for colon polyps. The weighted pooled estimates with 95 %CIs were calculated using the random effects model. I2 statistics were used to evaluate heterogeneity. RESULTS: 4137 articles were reviewed, and 16 studies, including 2592 polyps in 1922 patients (51.4 % female), were included. Overall, 54.4 % of polyps were adenomas, 45 % were sessile serrated lesions (SSLs), and 0.6 % were invasive carcinomas. Polyp recurrence after CS-EMR was 6.7 % (95 %CI 2.4 %-17.4 %, I2  = 94 %). The recurrence rate was 12.3 % (95 %CI 3.4 %-35.7 %, I2  = 94 %) for polyps ≥ 20 mm, 17.1 % (95 %CI 4.6 %-46.7 %, I2  = 93 %) for adenomas, and 5.7 % (95 %CI 3.2 %-9.9 %, I2  = 50 %) for SSLs. The pooled intraprocedural bleeding rate was 2.6 % (95 %CI 1.5 %-4.5 %, I2  = 51 %), the delayed bleeding rate was 1.5 % (95 %CI 0.8 %-2.7 %, I2  = 18 %), and no perforations or post-polypectomy syndromes were reported, with estimated rates of 0.6 % (95 %CI 0.3 %-1.3 %, I2  = 0 %) and 0.6 % (95 %CI 0.3 %-1.4 %, I2  = 0 %), respectively. CONCLUSION: CS-EMR demonstrated an excellent safety profile for colon polyps, with variable recurrence rates based on polyp size and histology. Large prospective studies are needed to validate these findings.

Influence of depression and interpersonal support on adherence to antiretroviral therapy among people living with HIV.

BACKGROUND: Poor adherence and under-utilization of antiretroviral therapy (ART) services have been major setbacks to achieving 95-95-95 policy goals in Sub-Saharan Africa. Social support and mental health challenges may serve as barriers to accessing and adhering to ART but are under-studied in low-income countries. The purpose of this study was to examine the association of interpersonal support and depression scores with adherence to ART among persons living with HIV (PLWH) in the Volta region of Ghana. METHODS: We conducted a cross-sectional survey among 181 PLWH 18 years or older who receive care at an ART clinic between November 2021 and March 2022. The questionnaire included a 6-item simplified ART adherence scale, the 20-item Center for Epidemiologic Studies Depression Scale (CES-D), and the 12-item Interpersonal Support Evaluation List-12 (ISEL-12). We first used a chi-squared or Fisher's exact test to assess the association between these and additional demographic variables with ART adherence status. We then built a stepwise multivariable logistic regression model to explain ART adherence. RESULTS: ART adherence was 34%. The threshold for depression was met by 23% of participants, but it was not significantly associated with adherence in multivariate analysis(p = 0.25). High social support was reported by 48.1%, and associated with adherence (p = 0.033, aOR = 3.45, 95% CI = 1.09-5.88). Other factors associated with adherence included in the multivariable model included not disclosing HIV status (p = 0.044, aOR = 2.17, 95% CI = 1.03-4.54) and not living in an urban area (p = 0.00037, aOR = 0.24, 95% CI = 0.11-0.52). CONCLUSION: Interpersonal support, rural residence, and not disclosing HIV status were independent predictors of adherence to ART in the study area.

Use of the endoscopic powered resection device for the management of scarred polyps.

Background and Aims: The endoscopic powered resection (EPR) device (EndoRotor, Interscope Inc, Northbridge, Mass, USA) is a novel nonthermal device that can be used for polyp and tissue removal in the GI tract. Here, we review the EPR device and illustrate its use for resection of scarred or fibrotic lesions in the GI tract. Methods: In this article and accompanying video, we describe the EPR device features, provide step-by-step instructions for device setup, and review case examples in which the EPR device was used for scarred polyp resection. We also review the current literature describing the use of the EPR device for scarred or challenging polyps. Results: Four lesions with scarring or fibrosis were successfully resected with the EPR device, either with the EPR device alone or as an adjunct to conventional resection methods. No adverse events occurred. A follow-up endoscopy was available in 1 case, which demonstrated no endoscopic or histologic evidence of residual or recurrent lesion. Conclusions: The endoscopic powered resection device can be used alone or as an adjunct to facilitate resection of lesions with significant fibrosis or scarring. This device serves as a useful addition to endoscopists' toolbox in the management of scarred lesions where other modalities might be technically challenging to use.

Performance of a Provider-Assigned Functional Outcome Score in Critically Ill Children.

OBJECTIVES: Determine agreement between Pediatric Cerebral Performance Category (PCPC) scores integrated into clinical workflow and traditional investigator-assigned scores. DESIGN: Longitudinal study. SETTING: A single-center quaternary-care academic institution. SUBJECTS: Children admitted to the PICU between November 2019 and April 2020. INTERVENTIONS: Providers assigned PCPC scores as part of daily workflow. Investigators assigned scores using retrospective chart review. MEASUREMENTS AND MAIN RESULTS: Of 803 patients admitted to the PICU, 782 survived and were included. Admission and discharge scores were recorded in 95% and 90% of patients, respectively. Agreement between provider- and investigator-assigned scores was excellent, with a weighted kappa of 0.87 (95% CI, 0.84-0.90) and 0.80 (95% CI, 0.76-0.84) for admission and discharge. CONCLUSIONS: Provider-assigned PCPC scores, documented as standard of care, are largely concordant with retrospective investigator-assigned scores. Measurement of cognitive functional status can be successfully integrated into daily provider workflow for use in the clinical, quality improvement, and research arenas.

The Difficulties of Grandiose Delusions: Harms, Challenges, and Implications for Treatment Engagement.

BACKGROUND AND HYPOTHESIS: Grandiose delusions may entail difficult responsibilities and detrimental actions for patients. Recognition of these consequences by patients may provide an avenue for engagement in treatment. Furthermore, when patients carry out actions within the delusional system ("immersion behaviors") or spend considerable time thinking about their grandiose beliefs this may contribute to the persistence of the grandiosity and further harmful consequences. We, therefore, investigated grandiose-related subjective harm, immersion behaviors, and perseverative thinking. STUDY DESIGN: A cross-sectional study with 798 patients with psychosis (375 of whom had grandiose delusions) and 4518 nonclinical adults. Factor analyses using data from participants scoring highly on grandiosity were used to form 3 scales: subjective harm from exceptional experiences questionnaire; immersion behaviors questionnaire; and thinking about exceptional experiences questionnaire. Associations with grandiosity were tested using structural equation modeling. STUDY RESULTS: A total of 268 (77.9%) patients with grandiose delusions identified grandiose-related harms in the past 6 months and 199 (55.1%) wanted help. Immersion behaviors and perseverative thinking were highly prevalent, and explained 39.5% and 20.4% of the variance in grandiosity, respectively. Immersion behaviors and perseverative thinking were significantly associated with subjective harm, even when severity of grandiosity was controlled. Requests for help were associated with higher levels of subjective harm, use of immersion behaviors, and perseverative thinking but not severity of grandiosity. CONCLUSIONS: Acting on grandiose delusions, including harmful behaviors and excessive thinking about grandiose delusions, may be routes for clinicians to engage patients in treatment. This could be a starting point for targeted psychological interventions for grandiose delusions.

Analysis of Reported Adverse Events Associated with Over-the-Scope Endoscopic Suturing System: an FDA MAUDE Database Study.

PURPOSE: The over-the-scope endoscopic suturing system (ESS) (OverStitch™) is one of the most widely utilized endoscopic suturing systems in current clinical practice; however, data on the adverse events associated with this device is scarce. Our study aims to evaluate the adverse events and complications associated with the over-the-scope ESS using the FDA's Manufacturer and User Facility Device Experience (MAUDE) database. MATERIALS AND METHODS: We analyzed the post-marketing surveillance data from the FDA MAUDE database for the over-the-scope ESS from January 2008 through June 2022. RESULTS: Eighty-three reports were filed from January 2008 to June 2022. Adverse events were classified as device-related complications and patient-related adverse events. Seventy-seven device-related issues and 87 patient adverse events were identified. The most common device-related issue was difficulty to remove after deployment (n=12, 15.58%) followed by mechanical problem (n=10, 12.99%), mechanical jam (n=9, 11.69%), or entrapment of device (n=9, 11.69%). Of the 87 patient-related adverse events, the most common was perforation (n=19; 21.84%), followed by device embedded in tissue or plaque (n=10; 11.49%), and abdominal pain (n=8; 9.20%). Of the 19 patients who experienced perforation, two required open surgical repair and one required laparoscopic surgical repair. CONCLUSION: The overall adverse events from the over-the-scope ESS remain acceptable as evidenced by the number of reported cases since 2008. However, it is important to note that adverse event rates might increase as the use of the device increases; therefore, it is essential for endoscopists to be aware of the potential common and rare adverse events associated with the use of the over-the-scope ESS device.

The Scottish COVID Cancer Immunity Prevalence Study: A Longitudinal Study of SARS-CoV-2 Immune Response in Patients Receiving Anti-Cancer Treatment.

BACKGROUND: Cancer and anti-cancer treatment (ACT) may be risk factors for severe SARS-CoV-2 infection and limited vaccine efficacy. Long-term longitudinal studies are needed to evaluate these risks. The Scottish COVID cancer immunity prevalence (SCCAMP) study characterizes the incidence and outcomes of SARS-CoV-2 infection and vaccination in patients with solid tumors undergoing ACT. This preliminary analysis includes 766 patients recruited since May 2020. METHODS: Patients with solid-organ cancers attending secondary care for active ACT consented to the collection of routine electronic health record data and serial blood samples over 12 months. Blood samples were tested for total SARS-CoV-2 antibody. RESULTS: A total of 766 participants were recruited between May 28, 2020 and October 31, 2021. Most received cytotoxic chemotherapy (79%). Among the participants, 48 (6.3%) were tested positive for SARS-CoV-2 by PCR. Infection rates were unaffected by ACT, largely aligning with the local population. Mortality proportion was not higher with a recent positive SARS-CoV-2 PCR (10.4% vs 10.6%). Multivariate analysis revealed lower infection rates in vaccinated patients regardless of chemotherapy (HR 0.307 [95% CI, 0.144-0.6548]) or immunotherapy (HR 0.314 [95% CI, 0.041-2.367]) treatment. A total of 96.3% of patients successfully raised SARS-CoV-2 antibodies after >2 vaccines. This was independent of the treatment type. CONCLUSION: This is the largest on-going longitudinal real-world dataset of patients undergoing ACT during the early stages of the COVID-19 pandemic. This preliminary analysis demonstrates that patients with solid tumors undergoing ACT have high protection from SARS-CoV-2 infection following COVID-19 vaccination. The SCCAMP study will evaluate long-term COVID-19 antibody trends, focusing on specific ACTs and patient subgroups.

Five Year Analyses of Vegetation Response to Restoration using Rock Detention Structures in Southeastern Arizona, United States.

Rock detention structures (RDS) are used in restoration of riparian areas around the world. The purpose of this study was to analyze the effect of RDS installation on vegetation in terms of species abundance and composition. We present the results from 5 years of annual vegetation sampling which focused on short term non-woody vegetation response within the riparian channel at 3 restoration sites across southeastern Arizona. We examined the potential ways that RDS can preserve native species, encourage wetland species, and/or introduce nonnative species using a Control-Impact-Paired-Series study design. Species composition and frequency were measured within quadrats and zones on an annual basis. Multivariate bootstrap analyses were performed, including Bray-Curtis dissimilarity index and non-metric multidimensional scaling ordination. We found that response to RDS was variable and could be related to the level of degradation or proximity to groundwater. The non-degraded site did not show a response to RDS and the severely degraded site showed a slight increase in vegetation frequency, but the moderately degraded site experienced a significant increase. At the moderately degraded site, located between two historic ciénegas (desert wetlands), species composition shifted and nonnative species invaded, dominating the vegetation increase at this location. At the severely degraded site, pre-existing wetland species frequency increased in response to the installation of RDS. These findings extend the understanding of RDS effects on vegetation, provide scenarios to help land and water resource managers understand potential outcomes, and can assist in optimizing success for restoration projects.
