RESUMEN
INTRODUCTION: This study examined the effects of a large-scale flipped learning (FL) approach in an undergraduate course of Digestive System Diseases. METHODS: This prospective non-randomized trial recruited 404 students over three academic years. In 2016, the course was taught entirely in a Traditional Lecture (TL) style, in 2017 half of the course (Medical topics) was replaced by FL while the remaining half (Surgical topics) was taught by TL and in 2018, the whole course was taught entirely by FL. Academic performance, class attendance and student's satisfaction surveys were compared between cohorts. RESULTS: Test scores were higher in the FL module (Medical) than in the TL module (Surgical) in the 2017 cohort but were not different when both components were taught entirely by TL (2016) or by FL (2018). Also, FL increased the probability of reaching superior grades (scores >7.0) and improved class attendance and students' satisfaction. CONCLUSION: The holistic FL model is more effective for teaching undergraduate clinical gastroenterology compared to traditional teaching methods and has a positive impact on classroom attendances.

OBJECTIVES: Despite Centers for Disease Control and Prevention guidelines on adult opioid prescribing, there is a paucity of evidence and no guidelines to inform opioid prescribing in pediatrics. To develop guidelines on pediatric prescribing, it is imperative to evaluate current practice on opioid use. The objectives were to describe prescribing patterns of opioids for acute pain at a children's hospital and to compare clinical characteristics of patients who received less or greater than 3 days. METHODS: A retrospective review of oral opioid analgesics prescribed for acute pain at a tertiary care children's hospital emergency department and urgent care from January 1, 2017, to December 31, 2017. Patients younger than 22 years who received an opioid prescription upon discharge were included. Patients with hematology/oncology or chronic pain diagnosis were excluded. RESULTS: Opioids were prescribed for a median of 2.2 days (interquartile range, 1.4-3.0 days). Most opioids were prescribed for ≤3 days (1326; 79.3%), and there were 44 (2.6%) prescriptions for >7 days. Twenty-two opioid formulations were prescribed. Single-ingredient oxycodone was the most commonly prescribed (877; 52.5%); there were 724 (43.3%) acetaminophen combination products. Common diagnoses were orthopedic (973; 58.2%), surgery/burn/trauma (195; 11.7%), and ear/nose/throat (143; 8.6%). Patients who received >3 days of opioids were younger (P < 0.001), and there was no differences in sex, ethnicity, insurance, or provider qualifications. CONCLUSIONS: Overall, prescribing patterns for the duration of opioid analgesics were ≤3 days, with a median of 2 days. There was a large range of days prescribed, with variations in prescribing characteristics among patients and providers.

BACKGROUND: The management of acute gastrointestinal hemorrhage (GIH) is focused on early resuscitation through 2 large-bore intravenous (2LBIV) catheters, although adherence to this recommendation is low. LOCAL PROBLEM: Of 100 patients hospitalized with GIH in 2017, only 14 received 2LBIV access. The goal of this study was to improve this measure. METHODS: A multidisciplinary team used the DMAIC (define, measure, analyze, improve, and control) framework to perform a quality improvement initiative. INTERVENTIONS: The team used quality tools including a stakeholder survey, swimlane diagram, and fishbone diagram. The first intervention involved education of the hospitalists directing admissions, and the second intervention involved education of emergency department (ED) physicians and nurses regarding the importance of 2LBIV placement. RESULTS: Following the second intervention, there was a substantial increase in 2LBIV placement to 37 of 86 (43%). CONCLUSIONS: Carefully directed education of ED physicians and nurses with monthly feedback was effective in improving appropriate intravenous placement in patients with GIH.

This study investigates the effect of addition of tannic acid on nisin encapsulated in chitosan matrices. Composite materials were prepared using a mild, environmentally friendly procedure, ionotropic gelation of chitosan by sodium tripolyphosphate in the presence of nisin (N) at different concentrations. In two parallel sets of preparations, tannic acid (TA) was added at 10:1 and 5:1 N:TA, respectively. The obtained particles were characterized by FTIR, SEM, size, zeta potential, encapsulation efficiency, loading capacity, and ratio of residual free amino groups. The kinetics of nisin release from the particles was studied to assess the role of TA as a potential modulator thereof. Its addition resulted in enhanced release, higher at lower N:TA ratio. An additional benefit was that TA, a strong antioxidant, imparted antioxidant activity to the composites. Antimicrobial turbidimetric tests were performed against one gram-positive bacterium (Staphylococcus aureus) and two gram-negative bacteria (Escherichia coli and Pseudomonas aeruginosa), all relevant for the food, pharmaceutical, and cosmetic industries. All the composites showed synergistic effects against all the bacteria tested. The positive coaction was stronger against the gram-negative species. This is remarkable since nisin by itself has not known activity against them.

BACKGROUND: Currently, there is a shortage of males holding faculty positions in schools of nursing. Minimal research has been conducted to address the shortage of male faculty. PURPOSE: The purpose of this study was to identify factors related to recruitment and retention of men in the faculty role. METHODS: In this multisite descriptive design, 242 male faculty completed the electronic Nurse Educator Recruitment and Retention Survey. RESULTS: Top strategies regarding attraction to the role were opportunity to work with students and to help shape the nursing profession, and nurse faculty role modeling. Top recruitment strategies were increased salaries, employee benefits, having discussions with students, and flexibility in working hours. Retention strategies reported were a positive work environment and support from administration. CONCLUSION: The factors identified from this study are essential for the recruitment and retention of men in faculty roles.

OBJECTIVE: Pediatric patients with sleep-disordered breathing (SDB) and obesity are at risk for opioid-induced respiratory depression. Although monitoring in the inpatient setting allows for early recognition of opioid-related adverse events, there is far less vigilance after ambulatory surgery as patients are discharged home. Guidelines for proper opioid dosing in these pediatric subsets have not been established. We sought to determine if at-risk children were more likely to receive doses of opioids outside the recommended range. METHODS: Baseline opioid prescribing data for all outpatient surgery patients receiving an opioid prescription between January 2019 and June 2020 were retrospectively reviewed. Patients with SDB or obesity were identified. To obtain more information about prescribing practices, we analyzed patient demographics, size descriptors used for calculations, and prescription characteristics (dose, duration, and prescribing surgical service). RESULTS: A total of 4674 patients received an opioid prescription after outpatient surgery. Of those, 173 patients had SDB and 128 were obese. Surgical subspecialties rendering most of the opioid prescriptions included otolaryngology and orthopedics. Obese patients were more likely (64%) to be prescribed opioids using ideal weight at higher mg/kg doses (>0.05 mg/kg; 83.3%; p < 0.0001). When providers used actual body weight, lower mg/kg doses were more likely to be used (53.7%; p < 0.0001). No prescriptions used lean body mass. CONCLUSIONS: Overweight/obese children were more likely to receive opioid doses outside the recommended range. Variability in prescribing patterns demonstrates the need for more detailed guidelines to minimize the risk of opioid-induced respiratory complications in vulnerable pediatric populations.
RESUMEN
Management of acute pain in children is fundamental to our practice. Its myriad benefits include reduced suffering, improved patient satisfaction, more rapid recovery, and a reduced risk of developing postsurgical chronic pain. Although a multimodal analgesic approach is now routinely used, informed and judicious use of opioid receptor agonists remains crucial in this treatment paradigm, as long as the benefits and risks are fully understood. Further, an ongoing public health response to the current opioid crisis is required to help prevent new cases of opioid addiction, identify opioid-addicted individuals, and ensure access to effective opioid addiction treatment, while at the same time continuing to safely meet the needs of patients experiencing pain.

OBJECTIVE: To investigate the statistical measures of the performance of 2 interventions: a) early sepsis identification by a computerized sepsis "sniffer" algorithm (CSSA) in the emergency department (ED) and b) human decision to activate a multidisciplinary early resuscitation sepsis and shock response team (SSRT). METHODS: This study used a prospective and historical cohort study design to evaluate the performance of two interventions. INTERVENTION: A computerized sepsis sniffer algorithm (CSSA) to aid in early diagnosis and a multidisciplinary sepsis and shock response team (SSRT) to improve patient care by increasing compliance with Surviving Sepsis Campaign (SSC) bundles. RESULTS: The CSSA yielded a sensitivity of 100% (95% CI, 99.13-100%) and a specificity of 96.2% (95% CI, 95.55-96.45%) to identifying sepsis in the ED (Table 1). The SSRT resource was activated appropriately in 34.1% (86/252) of patients meeting severe sepsis or septic shock criteria; the SSRT was inappropriately activated only three times in sepsis-only patients. In 53% (134/252) of cases meeting criteria for SSRT activation, the critical care team was consulted as opposed to activating the SSRT resource. CONCLUSION: Our two-step machine-human interface approach to patients with sepsis utilized an outstandingly sensitive and specific electronic tool followed by more specific human decision-making.

OBJECTIVE: To reduce door-to-angiographic reperfusion (DTR) time to 120 minutes for patients presenting with acute ischemic stroke attributed to anterior circulation large-vessel occlusion amenable to endovascular mechanical thrombectomy. PATIENTS AND METHODS: Patients treated with mechanical thrombectomy before (April 10, 2015, through April 11, 2016) and after (April 12, 2016, through May 10, 2017) implementation of a multitiered notification system were studied. Lean process mapping was used to assess inefficiencies with multidisciplinary triage. A 3-tiered paging platform, which rapidly alerts essential personnel of the acute ischemic stroke team at advancing decision points, was introduced. RESULTS: Sixty-two patients were analyzed before and after implementation (34 vs 28, respectively). Following intervention, DTR time was reduced by 43 minutes (mean DTR, 170 minutes vs 127 minutes; P=.02). At 90-day follow up, 5 of the 28 patients in the postintervention cohort (19%) had excellent neurologic outcomes, defined as a modified Rankin Scale score of 0, compared to 0 of 34 (0%) in the preintervention cohort (P=.89). Reductions were also seen in the length of stay on the neurocritical care service (mean, 6 vs 3 days; P=.006), and total hospital charges for combined groups (mean, $100,083 vs $161,458; P<.001). CONCLUSION: The multitiered notification system was a feasible solution for improving DTR within our institution, resulting in reductions of overall DTR time, neurocritical care service length of stay, and total hospital charges.
RESUMEN
Traditional slit-based spectrometers have an inherent trade-off between spectral resolution and throughput that can limit their performance when measuring diffuse sources such as light returned from highly scattering biological tissue. Recently, multielement fiber bundles have been used to effectively measure diffuse sources, e.g., in the field of spatially offset Raman spectroscopy, by remapping the source (or some region of the source) into a slit shape for delivery to the spectrometer. Another approach is to change the nature of the instrument by using a coded entrance aperture, which can increase throughput without sacrificing spectral resolution.In this study, two spectrometers, one with a slit-based entrance aperture and the other with a coded aperture, were used to measure Raman spectra of an analyte as a function of the optical properties of an overlying scattering medium. Power-law fits reveal that the analyte signal is approximately proportional to the number of transport mean free paths of the scattering medium raised to a power of -0.47 (coded aperture instrument) or -1.09 (slit-based instrument). These results demonstrate that the attenuation in signal intensity is more pronounced for the slit-based instrument and highlight the scattering regimes where coded aperture instruments can provide an advantage over traditional slit-based spectrometers.

Gastroesophageal reflux disease (GERD) is a chronic, recurrent disease that affects nearly 19 million people in the US. The mainstay of therapy for GERD is acid suppression. Proton pump inhibitors (PPIs) are the most effective medication for both initial treatment and maintenance therapy of GERD. Pantoprazole, a first-generation PPI, was approved by the FDA in 2000 for the treatment of erosive esophagitis associated with GERD. It has been used in more than 100 different countries worldwide. It is one of the few PPIs available in multiple forms: a delayed-release oral capsule, oral suspension, and intravenous. Pantoprazole been shown to improve acid reflux-related symptoms, heal esophagitis, and improve health-related quality of life more effectively than histamine-2 receptor antagonists. Evaluated in over 100 clinical trials, pantoprazole has an excellent safety profile, is as efficacious as other PPIs, and has a low incidence of drug interactions. It has also been shown to be safe and effective in special patient populations, such as the elderly and those with renal or moderate liver disease.
RESUMEN
Endoscopic retrograde cholangiopancreatography is an important tool in the diagnosis and treatment of pancreatobiliary diseases. A critical step in this procedure is deep cannulation of the bile duct as failure of cannulation generally results in an aborted procedure and failed intervention. Expert endoscopists usually achieve a high rate of successful cannulation while those less experienced typically have a much lower rate and a greater incidence of complications. Prolonged attempts at cannulation can result in significant morbidity to patients, anxiety for endoscopists, unnecessary radiation exposure and inefficient patient care. Here we review the most common endoscopic techniques used to achieve selective biliary cannulation. Pharmacologic aids to cannulation are also discussed briefly in this review.
