Additive inclusion in plastic life cycle assessments, part II: Review of additive inventory data trends and availability.

Plastic additives are as essential as polymers to the production and performance of plastic materials. Additive content can vary in composition and functionality depending on the product, producer, application, and production method. Such variation may be a barrier to achieving high-quality recycling and planning for plastic circular economy futures.

Five-Year Outcomes from a Prospective Study on Safety and Efficacy of Phasix ST Mesh Use at the Hiatus During Paraesophageal Hernia Repair.

Background: Laparoscopic paraesophageal hernia (PEH) repair has a high hernia recurrence rate. The aim of this study was to assess the 5-year hernia recurrence rate after PEH repair using a combination of bioresorbable mesh and advanced surgical techniques to address tension as needed in a prospective group of patients.

Study Design: In 2016, a prospective database was established for 50 patients undergoing primary, elective PEH repair with a new bioresorbable mesh (Phasix ST).

Updated Markov Model to Determine Optimal Management Strategy for Patients with Paraesophageal Hernia and Symptoms, Cameron Ulcer, or Comorbid Conditions.

Background: The current paradigm of watchful waiting (WW) in people 65 years or older with an asymptomatic paraesophageal hernia (PEH) is based on a now 20-year-old Markov analysis. Recently, we have shown that elective laparoscopic hernia repair (ELHR) provides an increase in life-years (L-Ys) compared with WW in most healthy patients aged 40 to 90 years. However, elderly patients often have comorbid conditions and may have complications from their PEH such as Cameron lesions.

Missed Opportunities: the Timing and Frequency of Screening Colonoscopy in Patients That Develop Esophageal Adenocarcinoma.

Introduction: Screening colonoscopy (SC) is widely accepted and has been shown to decrease the rate of colorectal cancer death. Guidelines and acceptance of screening for Barrett's esophagus (BE) are less established despite the fact that esophageal adenocarcinoma (EA) remains the fastest increasing cancer in the USA. The aim of this study was to assess the timing and frequency of SC in patients ultimately found to have EA and to evaluate the presence of symptoms and risk factors that might have prompted an esophagogastroduodenoscopy (EGD) and potentially earlier diagnosis of the EA.

Baseline plasma proinsulin response to glucose for predicting therapeutic response to otelixizumab in recent-onset type 1 diabetes.

Aims: In recent-onset type 1 diabetes, clamp-derived C-peptide predicts good response to anti-CD3. Elevated proinsulin and proinsulin/C-peptide ratio (PI/CP) suggest increased metabolic/inflammatory beta cell burden. We reanalyzed trial data to compare the ability of baseline acutely glucose-stimulated proinsulin, C-peptide and PI/CP to predict functional outcome.

Elective Laparoscopic Paraesophageal Hernia Repair Leads to an Increase in Life Expectancy Over Watchful Waiting in Asymptomatic Patients: An Updated Markov Analysis.

Objective: The aim of this study was to perform an updated Markov analysis to determine the optimal management strategy for patients with an asymptomatic paraesophageal hernia (PEH): elective laparoscopic hernia repair (ELHR) versus watchful waiting (WW).

Background: Currently, it is recommended that patients with an asymptomatic PEH not undergo repair based on a 20-year-old Markov analysis. The current recommendation might lead to preventable hospitalizations for acute PEH-related complications and compromised survival.

Tumor differentiation impacts response to neoadjuvant therapy and survival in patients with esophageal adenocarcinoma.

Objective: The current staging system for esophageal adenocarcinoma only considers tumor grade in early tumors. The aim of this study was to evaluate the impact of tumor differentiation on response to neoadjuvant chemoradiotherapy and survival in patients with locally advanced esophageal adenocarcinoma.

Methods: This was a multi-institution retrospective review of all patients with esophageal cancer who underwent neoadjuvant chemoradiotherapy followed by esophagectomy from January 2010 to December 2017.

Early emergency department discharge for intermediate heart score patients presenting for chest pain.

Study Objective: The use of the HEART score to risk stratify patients for short-term major adverse cardiac events in the emergency department (ED) setting is well established. Although discharge to home for low-risk HEART score patients is widely accepted as safe practice, there are limited outcomes data on moderate-risk HEART score patients discharged to home. We investigated the safety of discharging moderate-risk HEART score patients to home from the ED with established early cardiology follow-up.

Diaphragmatic relaxing incisions for complex hiatal reconstruction: longer-term follow-up confirms safety, efficacy and rare complications.

Background: Tension is an important factor in hernia repairs. Relaxing incisions to reduce tension are common with ventral hernia repairs, and techniques for relaxing incisions also exist for the hiatus. The aim of this study was to update our original experience with a diaphragm relaxing incision (DRI) in a larger group of patients with longer follow-up.

Prognostic value of left ventricular global constructive work in patients with cardiac amyloidosis.

Purpose: The aim of the present study was to evaluate the role of ejection fraction (EF), left ventricular (LV) global longitudinal strain (LVGLS) and global constructive work (GCW) as prognostic variables in patients with cardiac amyloidosis (CA).

Methods: CA patients were retrospectively identified between 2015 and 2021 at a tertiary care hospital. Comprehensive clinical, biochemical, and imaging evaluation including two-dimensional (2D) echocardiography with myocardial work (MW) analysis was performed.

The Nissen-Hill Hybrid Repair: Experience With the First 500.

Introduction: A new repair for gastroesophageal reflux and hiatal hernia, the Nissen-Hill hybrid repair, was developed to combine the relative strengths of its component repairs with the aim of improved durability. In several small series, it has been shown to be safe, effective, and durable for paraesophageal hernia, Barrett esophagus, and gastroesophageal reflux disease. This study represents our experience with the first 500 consecutive repairs for all indications.

Multicenter randomized controlled trial comparing forceps biopsy sampling with wide-area transepithelial sampling brush for detecting intestinal metaplasia and dysplasia during routine upper endoscopy.

Background And Aims: Intestinal metaplasia (IM) in the esophagus is a potentially premalignant mucosal change. The aim of this study was to compare the frequency of IM detection during upper endoscopy by forceps biopsy sampling (FB) versus wide-area transepithelial sampling (WATS) brush.

Methods: Patients presenting for upper endoscopy for foregut symptoms or surveillance of Barrett's esophagus (BE) at 9 centers in the United States were randomized to either FB or WATS.

Performance of Abbott Alinity hq hematology analyzer for automated cell counting of body fluids.

Introduction: Body fluid cell counting and differentiation provide essential information for diagnosis and monitoring of diverse pathologies. We evaluated the performance of the newly launched Abbott Alinity hq hematology analyzer for automated cell counting in body fluids and compared red blood cell (RBC) and total nucleated cell (TNC) counts with the Cell-Dyn Sapphire automated hematology analyzer. Differential counts were compared with microscopic differentiation on cytocentrifuged preparations.

Can We Identify Patients Appropriate for Same-Day Discharge After Laparoscopic Fundoplication?

Patients, surgeons, and payers are interested in reducing hospital length of stay. Outpatient laparoscopic fundoplication (LF) can be done safely and cost effectively. There is low acceptance of this practice due to fear of readmission and patient dissatisfaction.

High Resolution Manometry in a Functioning Fundoplication - Establishing a Standard Profile: Retrospective Chart Review.

Objective: The aim of this study was to provide a full HRM data set in patients with a normal functioning fundoplication.

Background: The Chicago classification was devised to correlate HRM values to the clinical status of patients with swallowing disorder. However, it is unclear whether those values are applicable after fundoplication as the literature is sparse.

POEM: clinical outcomes beyond 5 years.

Background: The short-term success of peroral endoscopic myotomy (POEM) is well documented but the durability of the operation is questioned. The aim of this study was to evaluate the clinical outcomes of the POEM procedure for esophageal motility disorders in a large cohort in which all patients had at least 5 years of follow-up.

Methods: All patients from a single center who underwent a POEM between October 2010 and September 2014 were followed for long-term clinical outcomes.

The Development and Natural History of Hiatal Hernias: A Study Using Sequential Barium Upper Gastrointestinal Series.

Objective: The aim of this study was to use barium upper gastrointestinal series (UGI) to evaluate the development and natural history of a hiatal hernia.

Summary Of Background Data: Hiatal hernias are common but the natural history of sliding and paraesophageal type hernias is poorly understood.

Methods: We reviewed UGI reports from 1987 to 2017 using a word scanning software program to identify individuals that had a hiatal hernia.

Safety and efficacy of magnetic sphincter augmentation dilation.

Background: The magnetic sphincter augmentation device (MSA) provides effective relief of gastroesophageal reflux symptoms. Dysphagia after MSA implantation sometimes prompts endoscopic dilation. The manufacturer's instructions are that it be performed 6 or more weeks after implantation under fluoroscopic guidance to not more than 15 mm keeping 3 or more beads closed.

Adequacy of EGD Reporting: a Review of 100 Reports from 100 Endoscopists.

Introduction: Esophagogastroduodenoscopy (EGD) is commonly performed in patients with gastroesophageal reflux disease (GERD). An EGD report should document pertinent findings such as esophagitis, a columnar-lined esophagus (CLE), the location of the squamo-columnar and gastroesophageal junctions, the size and type of a hiatal hernia and the number and location of any biopsies. The aim of this study was to evaluate how commonly these findings were noted in the EGD reports of patients referred for antireflux surgery.
