Clinical outcomes in a U.S. registration study of a new EDOF intraocular lens with a nondiffractive design.

Purpose: To evaluate the effectiveness and safety of the DFT015 intraocular lens (IOL) (AcrySof IQ Vivity Extended Vision) compared with an aspheric monofocal control IOL (AcrySof IQ model SN60WF).

Setting: 11 investigation sites in the U.S.

Multicountry clinical outcomes of a new nondiffractive presbyopia-correcting IOL.

Purpose: To evaluate the effectiveness and safety of a new presbyopia-correcting intraocular lens (IOL) with a nondiffractive design, DFT015, compared with an aspheric monofocal IOL, SN60WF.

Setting: 19 investigational sites in 4 countries: Australia, Canada, Spain, and the United Kingdom.

Design: Prospective, randomized, parallel-group, controlled, assessor- and patient-masked clinical study.

Visual Demand and Acuity Reserve of Chinese versus English Newspapers.

Significance: This study suggests that Chinese newspaper characters are more legible than English newspaper letters. Characters in Chinese newspapers have higher acuity reserve than English newspapers.

Purpose: The purpose of this study was to evaluate visual demand and acuity reserve for Chinese newspapers in comparison with published data on U.

Urban and rural differences in older drivers' failure to stop at stop signs.

Our purpose was to determine visual and cognitive predictors for older drivers' failure to stop at stop signs. 1425 drivers aged between ages 67 and 87 residing in Salisbury Maryland were enrolled in a longitudinal study of driving. At baseline, the participants were administered a battery of vision and cognition tests, and demographic and health questionnaires.

Specialist discrimination of toxic exposure severity at a poison control center.

Background: Perceived severity has been shown to affect decision-making processes in telephone triage. However, the accuracy of specialists in poison information's (SPIs') perceptions of severity of poison exposures is unknown.

Objective: The purpose of this study was to describe the ability of SPIs to predict severity of medical outcome on the basis of the information obtained during the initial poison control center's phone call.

Visual and cognitive deficits predict stopping or restricting driving: the Salisbury Eye Evaluation Driving Study (SEEDS).

Purpose: To determine the visual and other factors that predict stopping or restricting driving in older drivers.

Methods: A group of 1425 licensed drivers aged 67 to 87 years, who were residents of greater Salisbury, participated. At 1 year after enrollment, this group was categorized into those who had stopped driving, drove only within their neighborhood, or continued to drive beyond their neighborhood.

SAS macros for testing statistical mediation in data with binary mediators or outcomes.

Background: Statistical mediation is an important tool in behavioral health sciences, but it has been confined primarily to continuous variables. As prevention studies become increasingly common, more often the mediator or outcome is binary. Recent work by D.

Poison control center communication and impact on patient adherence.

Objective: This project explored the communication processes associated with poison control center calls.

Methods: In this preliminary study, we adapted the Roter Interaction Analysis System to capture staff-caller dialogue. This involved case selection, wherein adherence and non-adherence cases were selected; call linkage to medical records, where case records were linked with voice recordings; and application of Roter Interaction Analysis System to calls.

Matching waveform audio files with toxicall data: Record linkage in a poison control center.

Analysis of coded communications and electronic patient record data present a unique opportunity for nursing knowledge discovery, the integration of communication content with clinical data. However, joint analysis of coded communications and clinical data depends on the ability to link waveform audio files with patient records. A procedure has been developed to link waveform audio files with Toxicall patient records, using date/time stamps and station identification numbers.
