This supports the need to reconsider the commonly used "hard" clinical endpoints to evaluate therapeutic trials in GERD.
Response to a trial of proton pump inhibitors (PPIs) is currently accepted as a first step in the management of gastroesophageal reflux disease (GERD). However, information on the diagnostic performance of the PPI test is limited.
The aim of this study was to determine the diagnostic accuracy of the PPI test in GERD and noncardiac chest pain (NCCP) and to assess the test performance in erosive reflux disease (ERD) and nonerosive reflux disease (NERD).
Web of Science, Cochrane Controlled Register of Trials (CENTRAL), and MEDLINE were searched for studies reporting the diagnostic accuracy of the PPI test in adult patients with typical GERD and NCCP who underwent evaluation using an accepted reference standard, from January 1, 1950, through February 1, 2021. Subgroup analyses were performed, and the risk of bias was assessed with the Quality Assessment of Diagnostic Accuracy Studies-2 tool.
Nineteen studies (GERD=11, NCCP=8) involving 1691 patients were included. In GERD, the PPI test had 79% pooled sensitivity [95% confidence interval (CI), 72%-84%], and 45% pooled specificity (95% CI, 40%-49%). In NCCP, pooled sensitivity and specificity were 79% (95% CI, 69%-86%) and 79% (95% CI, 69%-86%), respectively. In ERD, the PPI test had 76% pooled sensitivity (95% CI, 66%-84%) and 30% pooled specificity (95% CI, 8%-67%). In NERD, the PPI test had 79% pooled sensitivity (95% CI, 70%-86%) and 50% pooled specificity (95% CI, 39%-61%).
The PPI test was sensitive in GERD but with suboptimal specificity. The test performed better in GERD-related NCCP. Diagnostic accuracy was comparable in ERD and NERD.

We sought to document patient perceptions in 2021 regarding colonoscopy experience and potential deterrents to repeat colonoscopy.
Bowel preparation has been previously considered by patients to be the worst part of a colonoscopy.
We conducted a prospective survey of consecutive patients age 18 years and older who had just completed colonoscopy at 2 outpatient endoscopy centers at a tertiary academic hospital. The short survey was conducted in the recovery area. The main outcome measure was patient perceptions of the worst part of their colonoscopy experience and which factor would most deter them from a future colonoscopy.
Four hundred patients completed the survey of 405 approached. Average patient age was 64 years, and 48% were women. Seventy-five percent of patients used low-volume preparations. Bowel preparation was considered the worst part of colonoscopy by 71% of patients. Women were more likely to choose laxatives as the worst part of a colonoscopy. Bowel preparation was chosen most often (55%) as the most likely deterrent to a future colonoscopy. There were minimal differences in responses between those receiving low-volume versus high-volume (4 L) preparations.
Bowel preparation remains the worst part of the colonoscopy experience for patients, and the most likely deterrent to future colonoscopy.

Pancreatic cancer (PC) is the third leading cause of cancer death. Obesity can increase the risk of PC by up to 50%. Studies have shown racial and gender disparities in PC, however, there is a paucity of such information in obese PC patients.
The aim of this study was to (1) evaluate the incidence and prevalence of obesity among PC patients in the United States over the last 15 years, and (2) determine if variation exists in the demographic of obese PC patients over the last 15 years. It is hoped that this information could be used to assist in primary prevention and early detection of PC.
A population-based retrospective analysis in IBM Explorys, a pooled, national, deidentified database of 63 million patients from 300 hospitals in the United States. Patient populations were identified using SNOMED and ICD codes. Cochrane-Armitage testing was performed to analyze trends in obesity among PC. Subgroup analysis for gender, age, race, and mortality rate were assessed.
The percentage of obese patients with PC increased over the 15-year period (2.5% to 8.5%, P<0.0001). Rates of obesity among PC patients increased among females (P=0.0004), individuals under age 65 years (P=0.0002), and all races, but especially for African Americans (P=0.0007) and those in minority groups.
Awareness of disparities in PC and applying targeted care to those at increased risk are essential to improve future outcomes, including increased health care access and recruitment in research studies for minority groups.

Biomechanical platelet activation is incompletely understood and is a potential mechanism behind antiplatelet medication resistance. Although it has been demonstrated that antiplatelet drugs suppress the growth of abdominal aortic aneurysms (AAA) in patients, we found that a certain degree of platelet reactivity persisted in spite of aspirin therapy, urging us to consider additional antiplatelet therapeutic targets. Transcriptomic profiling of platelets from patients with AAA revealed upregulation of a signal transduction pathway common to olfactory receptors, and this was explored as a mediator of AAA progression. Healthy platelets subjected to D-flow ex vivo, platelets from patients with AAA, and platelets in murine models of AAA demonstrated increased membrane olfactory receptor 2L13 (OR2L13) expression. A drug screen identified a molecule activating platelet OR2L13, which limited both biochemical and biomechanical platelet activation as well as AAA growth. This observation was further supported by selective deletion of the OR2L13 ortholog in a murine model of AAA that accelerated aortic aneurysm growth and rupture. These studies revealed that olfactory receptors regulate platelet activation in AAA and aneurysmal progression through platelet-derived mediators of aortic remodeling.Identifying predictive biomarkers at early stages of inflammatory arthritis is crucial for starting appropriate therapies to avoid poor outcomes. Monocytes (MOs) and macrophages, largely associated with arthritis, are contributors and sensors of inflammation through epigenetic modifications. In this study, we investigated associations between clinical features and DNA methylation in blood and synovial fluid (SF) MOs in a prospective cohort of patients with early inflammatory arthritis. DNA methylation profiles of undifferentiated arthritis (UA) blood MOs exhibited marked alterations in comparison with those from healthy donors. We identified additional differences both in blood and SF MOs after comparing patients with UA grouped by their future outcomes, i.e., good versus poor. Patient profiles in subsequent visits revealed a reversion toward a healthy level in both groups, those requiring disease-modifying antirheumatic drugs and those who remitted spontaneously. Changes in disease activity between visits also affected DNA methylation, which was partially concomitant in the SF of UA and in blood MOs of patients with rheumatoid arthritis. AZD4547 FGFR inhibitor Epigenetic similarities between arthritis types allow a common prediction of disease activity. Our results constitute a resource of DNA methylation-based biomarkers of poor prognosis, disease activity, and treatment efficacy for the personalized clinical management of early inflammatory arthritis.HIV-1 vaccine efforts are primarily directed toward eliciting neutralizing antibodies (nAbs). However, vaccine trials and mother-to-child natural history cohort investigations indicate that antibody-dependent cellular cytotoxicity (ADCC), not nAbs, correlate with prevention. The ADCC characteristics associated with lack of HIV-1 acquisition remain unclear. Here, we examine ADCC and nAb properties in pretransmission plasma from HIV-1-exposed infants and from the corresponding transmitting and nontransmitting mothers' breast milk and plasma. Breadth and potency (BP) were assessed against a panel of heterologous, nonmaternal variants. ADCC and neutralization sensitivity were estimated for the strains in the infected mothers. Infants who eventually acquired HIV-1 and those who remained uninfected had similar pretransmission ADCCBP. Viruses circulating in the transmitting and nontransmitting mothers had similar ADCC susceptibility. Infants with higher pretransmission ADCCBP and exposure to more ADCC-susceptible strains were less likely to acquire HIV-1. In contrast, higher preexisting infant neutralization BP and greater maternal virus neutralization sensitivity did not associate with transmission. Infants had higher ADCCBP closer to birth and in the presence of high plasma IgG relative to IgA levels. Mothers with potent humoral responses against their autologous viruses harbored more ADCC-sensitive strains. ADCC sensitivity of the exposure variants and preexisting ADCCBP influenced mother-to-child HIV-1 transmission during breastfeeding. Vaccination strategies that enhance ADCC are likely insufficient to prevent HIV-1 transmission because some strains may have low ADCC susceptibility.
Aim of this paper is to present a guide for translating to practice an evidence-based set of Quality Criteria and Recommendations (QCR) to promote the implementation of policies and practices in the field of health promotion, disease prevention and care for people with chronic diseases.
The guide is based on real-world experiences of eight European pilot actions using QCR as a framework for practice design, development, implementation, monitoring and evaluation. All partners implemented their respective practices by following the same agreed process.
The implementation method was summarized in seven steps where each of one outline a particular phase of the process. The guide provides a step-by-step tutorial for the implementation of QCR.
Practical experiences from the pilot actions show the potential value of using the QCR in designing and implementing practices to improve the quality of care for people with chronic diseases.

This work aims to identify policies implemented for healthy food environments in Italy within The Healthy Food Environment Policy Index (Food-EPI) project.
Food-EPI tool, which includes two components, thirteen domains and fifty good practice indicators, was adapted for the Italian context. Evidence for implementation was gathered and summarized for all fifty indicators from data sources such as governmental websites, non-government organizations publications and websites and via direct contact with Government officials.
The highest level of evidence was found within five domains food composition (2/2 indicators), labelling (3/4), promotion (4/5), provision (4/5) and leadership (5/5). The domains with less identified evidence were food prices (1/4), food in retail (0/4), trade and investment (0/2) and platforms and interaction (1/4).
The evidence summarization and the upcoming stakeholders' meeting to rate the level of implementation for each indicator in Italy have the potential to improve Government commitment to shape healthier food environments.
