Laryngopharyngeal reflux (LPR) symptoms are often present in patients with Gastroesophageal reflux disease (GERD). Whereas antireflux surgery (ARS) provides predictably excellent results in patients with typical GERD, those with atypical symptoms have variable outcomes. The goal of this study was to characterize the response of LPR symptoms to antireflux surgery. Patients who underwent ARS between January 2009 and May 2020 were prospectively identified from a single institutional database. Patient-reported information on LPR symptoms was collected at standardized time points (preoperative and 2 weeks, 8 weeks, and 1 year postoperatively) using a validated Reflux Symptom Index (RSI) questionnaire. Patients were grouped by preoperative RSI score: ≤ 13 (normal) and > 13 (abnormal). Baseline characteristics were compared between groups using chi-square test or t-test. A mixed effects model was used to evaluate improvement in RSI scores. One hundred and seventy-six patients fulfilled inclusion criteria (mean age 57.8 years, 70% female, mean BMI 29.4). Patients with a preoperative RSI ≤ 13 (n = 61) and RSI > 13 (n = 115) were similar in age, BMI, primary reason for evaluation, DeMeester score, presence of esophagitis, and hiatal hernia (p > 0.05). The RSI > 13 group had more female patients (80 vs 52%, p = 30) had the best response to ARS. When analyzing individual symptoms, the most likely to improve included heartburn, hoarseness, and choking. In our study population, patients with LPR symptoms achieved a rapid and durable response to antireflux surgery. Those with higher preoperative RSI scores experienced the greatest improvement. Our data suggest that antireflux surgery is a viable treatment option for this patient population.

INTRODUCTION: pH impedance testing is the most sensitive diagnostic test for detecting gastroesophageal reflux disease (GERD). The literature remains inconclusive on which preoperative pH impedance testing parameters are associated with an improvement in heartburn symptoms after anti-reflux surgery. The objective of this study was to evaluate which parameters on preoperative pH impedance testing were associated with improved GERD health-related quality of life (GERD-HRQL) following surgery. METHODS: Data from a single institution foregut database were used to identify patients with reflux symptoms who underwent anti-reflux surgery between 2014–2020. Acid and impedance parameters were extracted from preoperative pH impedance studies. GERD-HRQL was assessed pre- and postoperatively with a questionnaire that evaluated heartburn, dysphagia, and the impact of acid blocking medications on daily life. Patient characteristics, fundoplication type, and four pH impedance parameters were included in a multivariable linear regression model with improvement in GERD-HRQL as the outcome. RESULTS: We included 108 patients (59 Nissen and 49 Toupet fundoplications), with a median follow-up time of one year. GERD-HRQL scores improved from 22.4 (SD±10.1) preoperatively to 4.2 (±6.2) postoperatively. In multivariable analysis, a normal preoperative acid exposure time (p=0.01) and Toupet fundoplication (vs. Nissen; p=0.03) were independently associated with greater improvement in GERD-HRQL. CONCLUSIONS: Of the four pH impedance parameters that were investigated, a normal preoperative acid exposure time was associated with greater improvement in quality of life after anti-reflux surgery. Further investigation into the critical parameters on preoperative pH impedance testing using a multi-institutional cohort is warranted.

BackgroundAntibiotics are not recommended for treatment of acute uncomplicated bronchitis (AUB), but are often prescribed (85% of AUB visits within the Veterans Affairs nationally). This quality improvement project aimed to decrease antibiotic prescribing for AUB in community-based outpatient centres from 65% to MethodsFrom January to December 2018, community-based outpatient clinics’ 6 months’ average of prescribed antibiotics for AUB and upper respiratory infections was 63% (667 of 1054) and 64.6% (314 of 486) when reviewing the last 6 months. Seven plan–do–study–act (PDSA) cycles were implemented by an interprofessional antimicrobial stewardship team between January 2019 and March 2020. Balancing measures were a return patient phone call or visit within 4 weeks for the same complaint. Χ2 tests and statistical process control charts using Western Electric rules were used to analyse intervention data.ResultsThe AUB antibiotic prescribing rate decreased from 64.6% (314 of 486) in the 6 months prior to the intervention to 36.8% (154 of 418) in the final 6 months of the intervention. No change was seen in balancing measures. The largest reduction in antibiotic prescribing was seen after implementation of PDSA 6 in which 14 high prescribers were identified and targeted for individualised reviews of encounters of patients with AUB with an antimicrobial steward.ConclusionsOperational implementation of successful stewardship interventions is challenging and differs from the traditional implementation study environment. As a nascent outpatient stewardship programme with limited resources and no additional intervention funding, we successfully reduced antibiotic prescribing from 64.6% to 36.8%, a reduction of 43% from baseline. The most success was seen with targeted education of high prescribers.

Heller myotomy (HM) has historically been considered the gold standard treatment for achalasia. Peroral endoscopic myotomy (POEM) is a less-invasive procedure and offers a quicker recovery. Although some studies have compared short-term outcomes of HM and POEM, predictors of long-term dysphagia resolution remain unclear. The objective of this study was to evaluate patient-reported outcomes for achalasia patients who underwent either POEM or HM over a 9-year period. Data from our single academic institutional foregut database were used to identify achalasia patients who underwent HM or POEM from 2009 to 2018. Electronic health record data were reviewed to obtain patient characteristics and operative data. Achalasia severity stages were established for each patient using esophagram findings from an attending radiologist blinded to the procedure type. Postoperative outcomes were assessed via telephone for patients with at least 9 months of follow-up using Eckardt dysphagia scores. Patient age, sex, type of operation, and duration of follow-up were included in a multivariable linear regression model with Eckardt score as the outcome. Our cohort included 141 patients (97 HM and 44 POEM). Eighty-two patients completed a phone survey at the 9 months or greater time interval (response rate = 58%). Mean Eckardt scores were 2.98 and 2.53 at a median follow-up of 3 years and 1 year for HM and POEM patients, respectively (an Eckardt score ≤ 3 is considered a successful myotomy). Lower stages of achalasia on esophagram (e.g., Stage 0 vs. Stage 4) were associated with greater dysphagia improvement. On multivariable analysis, operative approach was not associated with a statistically significant difference in dysphagia outcomes. POEM and HM were associated with similar rates of dysphagia resolution for achalasia patients at a median of 2 years of follow-up. Both procedures appear to be durable options for achalasia treatment.

Chemical injuries from household products cause significant morbidity and mortality annually in pediatric patients. We present a rare case of a 21-month-old male with significant esophageal and cutaneous chemical burns secondary to non-accidental trauma. Given the unique challenges associated with multiple burn types we describe this case and provide a current review of the literature on the management of these potentially devastating injuries.

Background High-value healthcare focuses on improving healthcare to produce cost effective care, however limited information on the role of advanced practice registered nurses (APRNs) exists. Purpose This descriptive report describes APRN-led initiatives implemented as part of a national collaborative promoting the Choosing Wisely® campaign and high-value care measures. Method An APRN national collaborative focuses on developing and implementing high-value care initiatives. Monthly calls, podcasts, and a file sharing platform are used to facilitate the work of the national collaborative. Findings A total of 16 APRN teams from 14 states are participating and have implemented a number of initiatives to reduce unnecessary testing and treatments, promote appropriate antibiotic use, and promote optimal clinical practices such as mobility for hospitalized elderly patients, among others. Discussion A national collaborative has proven to be a successful way to engage APRN teams to focus on targeting high-value care and promoting evidence-based practices in clinical care.

Spirulina may increase people’s ability to resist mental and physical fatigue. This study tested that hypothesis in a randomized, double blinded, placebo controlled study in men. After 1 week, a 3 g/day dose of spirulina produced a small, but statistically significant increase in exercise output (Kcals consumed in 30 min exercise on a cross trainer machine). A mathematical based mental fatigue test showed improved performance 4 h after the first time of supplementation as well as 8 weeks later. Similarly, a subjective survey for a sense of physical and mental fatigue showed improvement within 4 h of the first supplementation as well as 8 weeks later. These results show that spirulina intake can affect fatigue in men.

Background 18F-fluorodeoxyglucose positron emission tomography (18F-FDG-PET) is widely used in diagnostic cancer imaging. However, the use of 18F-FDG in PET-based imaging is limited by its specificity and sensitivity. In contrast, anti-TAG (tumor associated glycoprotein)-72 monoclonal antibodies are highly specific for binding to a variety of adenocarcinomas, including colorectal cancer. The aim of this preliminary study was to evaluate a complimentary determining region (CDR)-grafted humanized CH2-domain-deleted anti-TAG-72 monoclonal antibody (HuCC49deltaCH2), radiolabeled with iodine-124 (124I), as an antigen-directed and cancer-specific targeting agent for PET-based imaging. Methods HuCC49deltaCH2 was radiolabeled with 124I. Subcutaneous tumor implants of LS174T colon adenocarcinoma cells, which express TAG-72 antigen, were grown on athymic Nu/Nu nude mice as the xenograft model. Intravascular (i.v.) and intraperitoneal (i.p.) administration of 124I-HuCC49deltaCH2 was then evaluated in this xenograft mouse model at various time points from approximately 1 hour to 24 hours after injection using microPET imaging. This was compared to i.v. injection of 18F-FDG in the same xenograft mouse model using microPET imaging at 50 minutes after injection. Results At approximately 1 hour after i.v. injection, 124I-HuCC49deltaCH2 was distributed within the systemic circulation, while at approximately 1 hour after i.p. injection, 124I-HuCC49deltaCH2 was distributed within the peritoneal cavity. At time points from 18 hours to 24 hours after i.v. and i.p. injection, 124I-HuCC49deltaCH2 demonstrated a significantly increased level of specific localization to LS174T tumor implants (p = 0.001) when compared to the 1 hour images. In contrast, approximately 50 minutes after i.v. injection, 18F-FDG failed to demonstrate any increased level of specific localization to a LS174T tumor implant, but showed the propensity toward more nonspecific uptake within the heart, Harderian glands of the bony orbits of the eyes, brown fat of the posterior neck, kidneys, and bladder. Conclusions On microPET imaging, 124I-HuCC49deltaCH2 demonstrates an increased level of specific localization to tumor implants of LS174T colon adenocarcinoma cells in the xenograft mouse model on delayed imaging, while 18F-FDG failed to demonstrate this. The antigen-directed and cancer-specific 124I-radiolabled anti-TAG-72 monoclonal antibody conjugate, 124I-HuCC49deltaCH2, holds future potential for use in human clinical trials for preoperative, intraoperative, and postoperative PET-based imaging strategies, including fused-modality PET-based imaging platforms.
