Background: The frequency of EoE has been increasing in Northern Hemisphere cohorts, yet there is a scarcity of data in our region. Regional climatic factors, and lifestyle habits may influence the presentation of EoE, and appropriate management is crucial to prevent complications. WIth this is mind we undertook the first comprehensive multisite study of EoE in Australasian children.

Web-based methods are crucial for researchers with nationally representative research objectives but without the resources of larger organizations. The web mode is appealing because it is inexpensive relative to in-person and telephone modes, and it affords a high level of privacy.

Study Design And Setting: The pilot interventions occurred from April 27, 2020, to August 3, 2020.
Objective: To evaluate trends in etiology and outcomes of neonatal liver failure (NLF) over 30 years retrospectively at a single institution.
Study Design: Inclusion criteria for this retrospective cohort study were babies presenting at a chronological age of ≤28 days between 1991 and 2020 with prothrombin time ≥20 seconds and biochemical liver injury. Demographics, etiology, laboratory investigations, need for extrahepatic organ support, acute kidney injury, and intervention with liver transplant (LT) were recorded.
The American Family Health Study (AFHS) collected family health and fertility data from a national probability sample of persons aged 18-49 between September 2021 and May 2022, using web and mail exclusively. In July 2022, we surveyed AFHS respondents and gauged their willingness to become part of a national web panel that would create novel longitudinal data on these topics. We focus on predictors of willingness to participate, identifying the potential selection bias that this type of approach may introduce.

The technique was pioneered on large national surveys, but the tools can also be applied on the smaller-scale surveys most commonly used by sociologists. We demonstrate responsive survey design in a small-scale, list-based sample survey of students on the topic of sexual misconduct.

The typical presentation usually includes a drug rash with eosinophilia and systemic symptoms (DRESS syndrome). Cases are typically mild and self-limiting, requiring supportive care only.

The design of the mailings is crucial to the success of the survey. We address the question of how to design invitation mailings that can grab potential respondents' attention and sway them to be interested in the survey in a short window of time.

Rapid detection and prompt treatment are critical; however, the only reliable method of diagnosis and monitoring is endoscopic graft biopsies. The required regular anesthetics are particularly problematic in children, and non-invasive strategies are needed.

Missing survey responses pose challenges to study conclusions. We describe missingness in All of Us baseline surveys.

This study analyzed data from an existing Internet panel of older people (age 50 and greater) who were offered participation into a momentary study (n = 3,169), which made it possible to compute uptake and to compare many characteristics of participation status. Momentary studies present participants with brief surveys multiple times a day over several days; these surveys ask about immediate or recent experiences.

For large national surveys that require household (HH) screening to determine survey eligibility, cost-efficient screening methods that do not include in-person visits need additional evaluation and testing. A new study, known as the American Family Health Study (AFHS), recently initiated data collection with a national probability sample, using a sequential mixed-mode mail/web protocol for push-to-web US HH screening (targeting persons aged 18-49 years).

Ownership of a bank account is an objective measure and should be relatively easy to elicit via survey questions. Yet, depending on the interview mode, the wording of the question and its placement within the survey may influence respondents' answers. The Health and Retirement Study (HRS) asset module, as administered online to members of the Understanding America Study (UAS), yielded substantially lower rates of reported bank account ownership than either a single question on ownership in the Current Population Survey (CPS) or the full asset module administered to HRS panelists (both interviewer-administered surveys).

The ongoing, national Monitoring the Future (MTF) panel study has traditionally used mailed paper surveys. In 2018, MTF experimented with a web-push data collection design for young adults ages 19-30, concluding that the web-push design improved response rates and did not change substance use estimates after controlling for sociodemographic characteristics (Patrick et al.
View Article and Find Full Text PDFLongitudinal surveys traditionally conducted by interviewers are facing increasing pressures to explore alternatives such as sequential mixed-mode designs, which start with a cheaper self-administered mode (online) then follow up using more expensive methods such as telephone or face-to-face interviewing. Using a designed experiment conducted as part of the 2018 wave of the Health and Retirement Study (HRS) in the US, we compare a sequential mixed-mode design (web then telephone) with the standard telephone-only protocol. Using an intent-to-treat analysis, we focus on response quality and response distributions for several domains key to HRS: physical and psychological health, financial status, expectations and family composition.

To date, EHCs have primarily been designed for face-to-face or telephone survey interviewing, and few calendar tools have been developed for more private, self-administered modes of data collection. Web surveys offer benefits in terms of both self-administration, which can reduce social desirability bias, and timeliness.

Methods: We review nine patients from the commencement of our transplantation program in 1986 up to 2020 assessing demographics, prognosis, and outcome measures.
Purpose: To measure the rate of recall of study participation and study attrition in survivors of acute respiratory distress syndrome(ARDS).
Materials/methods: In this ancillary study of the Re-evaluation of Systemic Early neuromuscular blockade(ROSE) trial, we measured the rate of study participation recall 3 months following discharge and subsequent study attrition at 6 months. We compared patient and hospital characteristics, and long-term outcomes by recall.
Background And Purpose: When planning and delivering radiotherapy, ideally bolus should be in direct contact with the skin surface. Varying air gaps between the skin surface and bolus material can result in discrepancies between the intended and delivered dose. This study assessed a three-dimensional (3D) printed flexible bolus to determine whether it could improve conformity to the skin surface, reduce air gaps, and improve planning target volume coverage, compared to a commercial bolus material, Superflab.
