Extended offset stems are infrequently required in anterior approach total hip arthroplasty and low usage does not compromise stability.

Introduction: Extended offset (EO) stems are commonly used in posterior approach (PA) total hip arthroplasty (THA), but usage rates and complications are not well studied with anterior approach (AA) THA. This study evaluated usage rates, radiographic outcomes and complications following AA THA between patients receiving EO stems and a matched cohort receiving standard offset (SO) stems.

Materials And Methods: This retrospective review evaluated 1515 consecutive AA THA performed between 2014 and 2021.

Complications following single-stage bilateral total knee arthroplasty and unilateral procedures: experience of a high-volume community hospital.

Introduction: The safety of single-stage bilateral total knee arthroplasty (SSBTKA) compared to unilateral total knee arthroplasty (TKA) remains controversial. The present study compares the 90-day postoperative complications encountered following SSBTKA and unilateral TKA in an unselected cohort of patients performed at a high-volume community hospital.

Materials And Methods: The perioperative electronic medical records of an unselected consecutive cohort of 1032 patients (1345 knees) having undergone unilateral or SSBTKA were reviewed.

Do older patients fare worse following unilateral or single stage bilateral total knee arthroplasty?

Introduction: The safety and benefits of single stage bilateral total knee arthroplasty (SSBTKA) among older patients as compared to unilateral TKA remains controversial. This study aimed to evaluate the influence of age and comorbidities on complications and early outcomes for unilateral and BTKA in patients over and under 70 years of age.

Materials And Methods: This prospective study compared postoperative complications and early patient-reported outcomes at 6 weeks of 142 unilateral TKA patients (N = 75, ≤ 70; N = 67, > 70) and 89 SSBTKA patients (N = 48, ≤ 70; N = 41, > 70).

Validation and Comparison of Nutrient Intakes from Two Dietary Questionnaires Developed for the Multiethnic Cohort Study.

Background: Quantitative food frequency questionnaires (QFFQs) are often used to measure dietary intakes in large cohort studies but the impact of updating these questionnaires over time is not often examined.

Objective: This study compared nutrient intakes estimated from two different QFFQs to each other and to intakes calculated from three 24-hour dietary recalls (24HDRs).

Design: This study used a cross-sectional design.

Dietary choline and betaine intakes vary in an adult multiethnic population.

Choline and betaine are important nutrients for human health, but reference food composition databases for these nutrients became available only recently. We tested the feasibility of using these databases to estimate dietary choline and betaine intakes among ethnically diverse adults who participated in the Multiethnic Cohort (MEC) Study. Of the food items (n = 965) used to quantify intakes for the MEC FFQ, 189 items were exactly matched with items in the USDA Database for the Choline Content of Common Foods for total choline, choline-containing compounds, and betaine, and 547 items were matched to the USDA National Nutrient Database for Standard Reference for total choline (n = 547) and 148 for betaine.

Evaluating the feasibility of utilizing the Automated Self-administered 24-hour (ASA24) dietary recall in a sample of multiethnic older adults.

The ASA24 is a web application which enables the collection of self-administered dietary recalls thus utilizing technology to overcome some of the limitations of traditional assessment methodologies. Older adults, particularly those from certain ethnic groups may have less access to and may be less receptive to technology. This research sought to determine the level of access to the internet as well as evaluate the feasibility of using a web-based alternative dietary data collection method in older, multiethnic adults.

A comparison of two systems for entering and assessing dietary data for a research study.

To reduce the cost of analyzing dietary data for research studies, we evaluated the accuracy of an entry and assessment system that could be used by trained food and nutrition professionals who did not routinely perform this type of task. We compared intakes from 24-hour recalls for 175 adult women and 185 schoolchildren using two methods for entry of dietary data. For the standard method, registered dietitians who routinely evaluate dietary data entered the recalls using a professional data entry program, RapidCalc.
