Campus source to sink wastewater surveillance of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2).

Wastewater-based surveillance (WBS) offers an aggregate, and cost-effective approach for tracking infectious disease outbreak prevalence within communities, that provides data on community health complementary to individual clinical testing. This study reports on a 16-month WBS initiative on a university campus in England, UK, assessing the presence of SARS-CoV-2 in sewers from large buildings, downstream sewer locations, raw wastewater, partially treated and treated effluents. Key findings include the detection of the Alpha (B.1.1.7) variant in wastewater, with 70 % of confirmed campus cases correlating with positive wastewater samples. Notably, ammonium nitrogen (NH4-N) levels showed a positive correlation (ρ = 0.543, p < 0.01) with virus levels at the large building scale, a relationship not observed at the sewer or wastewater treatment works (WWTW) levels due to dilution. The WWTW was compliant to wastewater standards, but the secondary treatment processes were not efficient for virus removal as SARS-CoV-2 was consistently detected in treated discharges. Tools developed through WBS can also be used to enhance traditional environmental monitoring of aquatic systems. This study provides a detailed source-to-sink evaluation, emphasizing the critical need for the widespread application and improvement of WBS. It showcases WBS utility and reinforces the ongoing challenges posed by viruses to receiving water quality.

Infected pancreatic necrosis-Current trends in management.

Acute necrotizing pancreatitis is a common gastrointestinal disease requiring hospitalization and multiple interventions resulting in higher morbidity and mortality. Development of infection in such necrotic tissue is one of the sentinel events in natural history of necrotizing pancreatitis. Infected necrosis develops in around 1/3rd of patients with necrotizing pancreatitis resulting in higher mortality. So, timely diagnosis of infected necrosis using clinical, laboratory and radiological parameters is of utmost importance. Though initial conservative management with antibiotics and organ support system is effective in some patients, a majority of patients still requires drainage of the collection by various modalities. Mode of drainage of infected pancreatic necrosis depends on various factors such as the clinical status of the patient, location and characteristics of collection and availability of the expertise and includes endoscopic, percutaneous and minimally invasive or open surgical approaches. Endoscopic drainage has proved to be a game changer in the management of infected pancreatic necrosis in the last decade with rapid evolution in procedure techniques, development of novel metal stent and dedicated necrosectomy devices for better clinical outcome. Despite widespread adoption of endoscopic transluminal drainage of pancreatic necrosis with excellent clinical outcomes, peripheral collections are still not amenable for endoscopic drainage and in such scenario, the role of percutaneous catheter drainage or minimally invasive surgical necrosectomy cannot be understated. In a nutshell, the management of patients with infected pancreatic necrosis involves a multi-disciplinary team including a gastroenterologist, an intensivist, an interventional radiologist and a surgeon for optimum clinical outcomes.

Intravenous Hemin, a potential heme oxygenase-1 activator, does not protect from post-ERCP acute pancreatitis in humans: Results of a randomized multicentric multinational placebo-controlled trial.

OBJECTIVE: Hemin, a heme oxygenase 1 activator has shown efficacy in the prevention and treatment of acute pancreatitis in mouse models. We conducted a randomized controlled trial (RCT) to assess the protective effect of Hemin administration to prevent post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) in patients at risk. METHODS: In this multicenter, multinational, placebo-controlled, double-blind RCT, we assigned patients at risk for PEP to receive a single intravenous dose of Hemin (4 mg/kg) or placebo immediately after ERCP. Patients were considered to be at risk on the basis of validated patient- and/or procedure-related risk factors. Neither rectal NSAIDs nor pancreatic stent insertion were allowed in randomized patients. The primary outcome was the incidence of PEP. Secondary outcomes included lipase elevation, mortality, safety, and length of stay. RESULTS: A total of 282 of the 294 randomized patients had complete follow-up. Groups were similar in terms of clinical, laboratory, and technical risk factors for PEP. PEP occurred in 16 of 142 patients (11.3%) in the Hemin group and in 20 of 140 patients (14.3%) in the placebo group (p = 0.48). Incidence of severe PEP reached 0.7% and 4.3% in the Hemin and placebo groups, respectively (p = 0.07). Significant lipase elevation after ERCP did not differ between groups. Length of hospital stay, mortality and severe adverse events rates were similar between groups. CONCLUSION: We failed to detect large improvements in PEP rate among participants at risk for PEP who received IV hemin immediately after the procedure compared to placebo.

The impact of a multidisciplinary team approach on the management of focal pancreatic lesions: a single tertiary center experience.

Background: Multidisciplinary team (MDT) meetings aim to optimize patient management. We evaluated the impact of MDT discussions on the management and diagnosis of focal pancreatic lesions in a single tertiary center. Methods: All patients with an initial diagnosis of solid or cystic pancreatic lesion discussed in our institution's MDT meeting on pancreatic diseases between January 1, 2020, and December 31, 2021, were included. The impact of MDT discussion on patient management, defined as a modification of the initially proposed therapeutic plan after MDT discussion, as well as the criteria leading to this modification, were the primary outcomes. Impact on diagnosis was the secondary outcome. Results: A total of 522 patients were included. Of these, 185 (35.4%) and 337 (64.6%) had an initial diagnosis of cystic or solid lesion, respectively. The most common referral query was regarding the management plan (349/522; 66.9%). Endoscopy was the procedure most often proposed before MDT discussion (109/522; 20.9%). Overall, the MDT discussion led to modification of the management plan in 377/522 patients (72.2%), with a statistically significant difference between cystic and solid lesions (63.2% vs. 77.2%; P<0.001). Management modifications were mainly driven by revision of cross-sectional radiological images. MDT discussion led to modification of the diagnosis in 92/522 patients (17.6%), with a significant difference regarding cystic lesions (35.7% vs. 7.7%; P<0.001). Conclusion: MDT discussion impacts the management of patients with cystic and solid pancreatic lesions, leading to a modification of the initially proposed management in two-thirds of them, mainly through revision of cross-sectional imaging.

Using Endoscopy in the Diagnosis of Pancreato-Biliary Cancers.

Pancreatic cancer and cholangiocarcinoma are life threatening oncological conditions with poor prognosis and outcome. Pancreatic cystic lesions are considered precursors of pancreatic cancer as some of them have the potential to progress to malignancy. Therefore, accurate identification and classification of these lesions is important to prevent the development of invasive cancer. In the biliary tract, the accurate characterization of biliary strictures is essential for providing appropriate management and avoiding unnecessary surgery. Techniques have been developed to improve the diagnosis, risk stratification, and management of pancreato-biliary lesions. Endoscopic ultrasound (EUS) and associated techniques, such as elastography, contrasted-enhanced EUS, and EUS-guided needle confocal laser endomicroscopy, may improve diagnostic accuracy. In addition, intraductal techniques applied during endoscopic retrograde cholangiopancreatography (ERCP), such as new generation cholangioscopy and in vivo cellular evaluation through probe-based confocal laser endomicroscopy, can increase the diagnostic yield in characterizing indeterminate biliary strictures. Both EUS-guided and intraductal approaches can provide the possibility for tissue sampling with new tools, such as needles, biopsies forceps, and brushes. At the molecular level, novel biomarkers have been explored that provide new insights into diagnosis, risk stratification, and management of these lesions.

Household Social Needs, Emotional Functioning, and Stress in Low-Income Latinx Children and their Mothers.

Latinx families may be particularly vulnerable to emotional dysfunction, due to higher rates of economic hardship and complex social influences in this population. Little is known about the impact of environmental stressors such as unmet social needs and maternal stress on the emotional health of Latinx children from low-income families. We conducted secondary analyses using survey and biomarker data from 432 Latinx children and mothers collected in a separate study. We used binomial and multinomial logistic regression to test if household social needs, or maternal perceived stress or hair cortisol concentration (HCC), predicted child measures of emotional functioning or child HCC, independent of relevant sociodemographic factors. Approximately 40% of children in the sample had symptoms consistent with emotional dysfunction, and over 37% of households reported five or more social needs. High perceived maternal stress predicted higher odds of child emotional dysfunction (OR = 2.15; 95% CI [1.14, 4.04]; p = 0.01), and high maternal HCC was positively associated with high child HCC (OR = 10.60; 95% CI [4.20, 26.74]; p < 0.01). Most individual household social needs, as well as the level of household social need, were not independently associated with child emotional dysfunction or child HCC. Our findings begin to define a framework for understanding emotional health, stress, and resilience when caring for Latinx children and mothers living with high levels of social need, and the need for integrated mental health and social needs screening and interventions in settings that serve this population.

COVID-19's Still-Urgent Lessons of Structural Inequality and Child Health in the United States.

COVID-19's lessons on structural inequality should have been painful and embarrassing to all of us. These daily experiences of an unacceptable status quo among US children are still with us in a post-COVID America. Addressing the multi-sectoral factors that undermine the nation...s health should remain urgent priorities for all health professionals.

Performance and safety of motorized spiral enteroscopy: a systematic review and meta-analysis.

BACKGROUND AND AIMS: The introduction of motorized spiral enteroscopy (mSE) into clinical practice holds diagnostic and therapeutic potential for small-bowel investigations. This systematic review and meta-analysis aims to evaluate the performance of this modality in diagnosing and treating small-bowel lesions. METHODS: A systematic search of MEDLINE, Cochrane, and ClinicalTrials.gov databases were performed through September 2022. The primary outcome was diagnostic success, defined as the identification of a lesion relative to the indication. Secondary outcomes were successful therapeutic manipulation, total enteroscopy rate (examination from the duodenojejunal flexion to the cecum), technical success (passage from the ligament of Treitz or ileocecal valve for anterograde and retrograde approach, respectively), and adverse event rates. We performed meta-analyses using a random-effects model, and the results are reported as percentages with 95% confidence intervals (CIs). RESULTS: From 2016 to 2022, 9 studies (959 patients; 42% women; mean age >45 years; 474 patients [49.4%] investigated for mid-GI bleeding/anemia) were considered eligible and included in analysis. The diagnostic success rate of mSE was 78% (95% CI, 72-84; I2 = 78.3%). Considering secondary outcomes, total enteroscopy was attempted in 460 cases and completed with a rate of 51% (95% CI, 30-72; I2 = 96.2%), whereas therapeutic interventions were successful in 98% of cases (95% CI, 96-100; I2 = 79.8%) where attempted. Technical success rates were 96% (95% CI, 94-97; I2 = 1.5%) for anterograde and 97% (95% CI, 94-100; I2 = 38.6%) for retrograde approaches, respectively. Finally, the incidence of adverse events was 17% (95% CI, 13-21; I2 = 65.1%), albeit most were minor adverse events (16%; 95% CI, 11-20; I2 = 67.2%) versus major adverse events (1%; 95% CI, 0-1; I2 = 0%). CONCLUSIONS: mSE provides high rates of diagnostic and therapeutic success with a low prevalence of severe adverse events.

Social Needs and Acculturation as Predictors of Emotional Problems and Perceived Stress Among Latinx Mothers with Low Income.

Associations between household social needs, acculturation, and emotional health remain understudied, particularly among Latinx mothers. We analyzed baseline survey data from 455 Latinx mothers in a previous study. Using multinomial regression, we examined whether emotional problems and perceived stress were associated with household social needs and acculturation. Almost half the sample reported four or more household social needs. Social needs cumulatively and independently predicted increased odds of frequent emotional problems or perceived stress. Lower acculturation predicted lower odds of frequent emotional problems. There is increased risk for emotional problems and stress in low-income Latinx mothers who experience high social need. Integrated social service and mental health care models may be one way to improve health outcomes. More research is needed to understand how clinical settings can leverage unique cultural protective factors to address the social and emotional health needs of Latinx mothers.

Efficacy of pharmacologic treatment for treating gastrointestinal angiodysplasias-related bleeding: a systematic review and meta-analysis.

INTRODUCTION: We evaluated the efficacy of pharmacologic treatments for patients with overt or occult bleeding due to gastrointestinal angiodysplasias (GIADs). METHODS: A systematic computer-aided literature search across Medline, Cochrane, Scopus and Embase databases was performed. Studies evaluating pharmacologic treatments for patients presenting with GIADs-related overt or occult bleeding were included. Post-treatment rebleeding was the primary outcome. Need for red blood cells (RBC) transfusion, post-treatment hemoglobin levels and adverse events rate comprised secondary outcomes. Results are presented as odds ratio (OR), mean difference (MD) or pooled rates (%) with 95% confidence intervals (95%CI). RESULTS: Four types of pharmacologic treatment were identified (25 studies): somatostatin analogs, hormonal therapy, thalidomide and angiogenesis inhibitors. Pharmacologic treatment of any kind led to significantly reduced bleeding episodes [OR (95% CI), 0.08 (0.04-0.18)]. No pharmacologic treatment was superior to others ( P = 0.46). Overall, pooled rebleeding rate post-treatment was 34% (26-43%). Similarly, significantly fewer patients required RBC transfusion during the post-treatment period [0.03 (0.03-0.07)], with no differences among various treatments ( P = 0.83), yielding an overall pooled transfusion rate of 33% (19-46%). Administration of pharmacological treatment led to significant improvement in terms of hemoglobin levels [MD (95% CI), 3.21 g/dL (2.42-3.99)]. The pooled rate of adverse events was 32% (22-42%). CONCLUSION: In patients with GIADs administration of any pharmacologic treatment significantly decreases rebleeding episodes and transfusions leading to higher hemoglobin values. One-third of them experience at least one adverse event related to the treatment.

Improving Children's Behavior in Seven Sessions: A Randomized Controlled Trial of Parent-Child Care (PC-CARE) for Children Aged 2-10 Years.

Parent-Child Care (PC-CARE) is a brief intervention for children with externalizing behaviors designed to address issues with their access to and retention in treatment. A growing evidence base of open trials and comparison studies support PC-CARE's benefits, but no randomized controlled trials (RCTs) of its effectiveness exist. The current study presents the first RCT of PC-CARE, a 7-session dyadic parenting intervention (trial number removed for blind review). Participants included a racially/ethnically diverse sample of 49 children (29% female) aged 2-10 years and their caregivers. Participants were randomly assigned to PC-CARE or waitlist control. Families participating in PC-CARE showed greater reductions in children's externalizing behaviors, improvements in children's adaptive skills, declines in parental stress, and increases in parents' positive communication skills, compared to families on the waitlist. The results of this first RCT of PC-CARE support the effectiveness of this brief intervention in improving children's behaviors.

Endoscopic internal drainage of complex bilomas and biliary leaks by transmural or transpapillary/transfistulary access.

BACKGROUND AND AIMS: Bilomas most frequently result from postoperative bile leaks. The endoscopic conventional treatment is sphincterotomy ± stent placement. In complex cases, such as altered anatomy or failure of conventional treatment, transpapillary/transfistulary (TP/TF) drainage or EUS-guided transmural drainage (EUS-TD) may obviate additional biliary surgery. This study reports our experience with treating biloma secondary to refractory biliary leak with TP/TF drainage or EUS-TD and evaluates the safety and outcomes associated with this approach. METHODS: This observational study focused on consecutive patients managed for biliary leakage (diagnosis based on imaging and/or bile outflow from a surgical drain) at a tertiary care hospital (2007-2017). TP/TF drainage was performed by double-pigtail stent(s) placement to drain the biloma through the leak during ERCP. For EUS-TD, plastic stent(s) were placed under EUS control. Primary outcomes were a composite of clinical success (patient free of sepsis after percutaneous drain removal and, in patients with benign disease, removal of all endoscopically placed stents, without need for reintervention) and biloma regression (<3 cm) at last follow-up. RESULTS: Thirty patients (men, 57%; median age, 55 years) were included. Most biliary leaks resulted from cholecystectomy (27%) and hepatectomy (50%). Initial EUS-TD and TP/TF drainage were performed in 14 (47%) and 16 (53%) patients, respectively. At last follow-up (median, 33.2 months), clinical success and primary outcome were achieved in 70.4% of patients (EUS-TD, 75%; TP/TF, 67%). Additional surgery was necessary in 1 patient. Rate of serious adverse events was 23% (7/30), of which 13% (4/30) were procedure related. There were 4 deaths during the course of treatment, 2 of which were related to endoscopic interventions (hemorrhage and fibrillation). CONCLUSIONS: TP/TF drainage or EUS-TD is technically feasible with high clinical success and may avoid the need for additional surgery in complex cases or in patients with altered anatomy.

Differential Use of Pediatric Video Visits by a Diverse Population During the COVID-19 Pandemic: A Mixed-Methods Study.

Objective: To describe and explore pediatric ambulatory video visit use by patient characteristics during the coronavirus disease 2019 (COVID-19) pandemic. Methods: We conducted an explanatory sequential mixed methods study with integration at the design and methods level. Phase 1 was a cross-sectional analysis of general and specialty pediatric ambulatory encounters to profile the use of video visits by patient characteristics. We performed descriptive analyses for each variable of interest and estimated a multivariable logistic regression model to analyze factors associated with the odds of having a video visit. Phase 2 was a qualitative exploration using semi-structured interviews with healthcare team members to understand the contextual factors influencing video visit usage. We used an interview guide to solicit information related to general perceptions about ambulatory video visits, reactions to the quantitative phase data, and strategies for optimizing equitable reach of video visits. Data were analyzed using a combination of deductive and inductive analysis. Results: Among the 5,464 pediatric ambulatory encounters completed between March 11 and June 30, 2020, 2,127 were video visits. Patient factors associated with lower odds of having a video visit rather than an in-person visit included being Spanish-speaking (aOR 0.27, 95% CI 0.20-0.37) and other non-English-speaking (aOR 0.50, 95% CI 0.34-0.75) in comparison to English-speaking. Patients with public insurance also had a lower odds of having a video visit in comparison to privately insured patients (aOR 0.77, 95% CI 0.67-0.88). Qualitative interviews identified five solution-based themes: (1) Promoting video visits in a way that reaches all patient families; (2) Offering video visits to all patient families; (3) Mitigating digital literacy barriers; (4) Expanding health system resources to support families' specific needs; and (5) Engaging and empowering health system personnel to expand video visit access. Conclusion: We identified differences in pediatric ambulatory video visit use by patient characteristics, with lower odds of video visit use among non-English-speaking and publicly insured patients. The mixed-methods approach allowed for the perspectives of our interview participants to contextualize the finding and lead to suggestions for improvement. Both our findings and the approach can be used by other health systems to ensure that all patients and families receive equal video visit access.

Curriculum for ERCP and endoscopic ultrasound training in Europe: European Society of Gastrointestinal Endoscopy (ESGE) Position Statement.

The European Society of Gastrointestinal Endoscopy (ESGE) has recognized the need to formalize and enhance training in endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound (EUS). This manuscript represents the outcome of a formal Delphi process resulting in an official Position Statement of the ESGE and provides a framework to develop and maintain skills in ERCP and EUS. This curriculum is set out in terms of the prerequisites prior to training; recommended steps of training to a defined syllabus; the quality of training; and how competence should be defined and evidenced before independent practice. 1: Trainees should be competent in gastroscopy prior to commencing training. Formal training courses and the use of simulation in training are recommended. 2: Trainees should keep a contemporaneous logbook of their procedures, including key performance indicators and the degree of independence. Structured formative assessment is encouraged to enhance feedback. There should be a summative assessment process prior to commencing independent practice to ensure there is robust evidence of competence. This evidence should include a review of a trainee's procedure volume and current performance measures. A period of mentoring is strongly recommended in the early stages of independent practice. 3: Specifically for ERCP, all trainees should be competent up to Schutz level 2 complexity (management of distal biliary strictures and stones > 10 mm), with advanced ERCP requiring a further period of training. Prior to independent practice, ESGE recommends that a trainee can evidence a procedure volume of > 300 cases, a native papilla cannulation rate of ≥ 80 % (90 % after a period of mentored independent practice), complete stones clearance of ≥ 85 %, and successful stenting of distal biliary strictures of ≥ 90 % (90 % and 95 % respectively after a mentored period of independent practice). 4: The progression of EUS training and competence attainment should start from diagnostic EUS and then proceed to basic therapeutic EUS, and finally to advanced therapeutic EUS. Before independent practice, ESGE recommends that a trainee can evidence a procedure volume of > 250 cases (75 fine-needle aspirations/biopsies [FNA/FNBs]), satisfactory visualization of key anatomical landmarks in ≥ 90 % of cases, and an FNA/FNB accuracy rate of ≥ 85 %. ESGE recognizes the often inadequate quality of the evidence and the need for further studies pertaining to training in advanced endoscopy, particularly in relation to therapeutic EUS.
