Dansyl Emits from a PICT Excited State.

Two derivatives of dansyl (1-dimethylamino-5-naphthalenesulfonyl) in which the amino group is constrained in a ring are prepared as neopentyl esters. Their photophysical behavior is compared with that of the dansyl ester. The solvatochromism and quantum yields are similar for all three.

Implant Removal After Internal Fixation of a Femoral Neck Fracture: Effects on Physical Functioning.

Objectives: The effect of implant removal after internal fixation of a femoral neck fracture on physical functioning was analyzed. Characteristics of patients who had their implant removed were studied, as it is currently unknown from which type of patients implants are removed and what effect removal has on function.

Design: Secondary cohort study alongside a randomized controlled trial.

Reliability, validity, and responsiveness of the Western Ontario and McMaster Universities Osteoarthritis Index for elderly patients with a femoral neck fracture.

Background: The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) has been extensively evaluated in groups of patients with osteoarthritis, yet not in patients with a femoral neck fracture. This study aimed to determine the reliability, construct validity, and responsiveness of the WOMAC compared with the Short Form-12 (SF-12) and the EuroQol 5D (EQ-5D) questionnaires for the assessment of elderly patients with a femoral neck fracture.

Methods: Reliability was tested by assessing the Cronbach alpha.

Cumulative incidence and treatment of non-simultaneous bilateral femoral neck fractures in a cohort of one thousand two hundred and fifty patients.

Purpose: In the Netherlands, over 20,000 patients sustain a hip fracture yearly. A first hip fracture is a risk factor for a second, contralateral fracture. Data on the similarity of the treatment of bilateral femoral neck fractures is only scarcely available.

Functional outcome after successful internal fixation versus salvage arthroplasty of patients with a femoral neck fracture.

Objectives: To determine patient independency, health-related and disease-specific quality of life (QOL), gait pattern, and muscle strength in patients after salvage arthroplasty for failed internal fixation of a femoral neck fracture.

Design: Secondary cohort study to a randomized controlled trial.

Setting: Multicenter trial in the Netherlands, including 14 academic and nonacademic hospitals.

Femoral neck shortening after internal fixation of a femoral neck fracture.

This study assesses femoral neck shortening and its effect on gait pattern and muscle strength in patients with femoral neck fractures treated with internal fixation. Seventy-six patients from a multicenter randomized controlled trial participated. Patient characteristics and Short Form 12 and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores were collected.

Adherence to a femoral neck fracture treatment guideline.

Purpose: In 2007 the Dutch Surgical Society published a clinical practice guideline for the treatment of hip fracture patients, based on the best available international evidence at that time. We investigated to what extent treatment of femoral neck fracture patients in the Netherlands corresponded with these guidelines, and determined differences in patient characteristics between the treatment groups.

Methods: All femoral neck fracture patients treated in 14 hospitals between February 2008 and August 2009 were included.

Central coordination as an alternative for local coordination in a multicenter randomized controlled trial: the FAITH trial experience.

Background: Surgeons in the Netherlands, Canada and the US participate in the FAITH trial (Fixation using Alternative Implants for the Treatment of Hip fractures). Dutch sites are managed and visited by a financed central trial coordinator, whereas most Canadian and US sites have local study coordinators and receive per patient payment. This study was aimed to assess how these different trial management strategies affected trial performance.

The epidemic of hip fractures: are we on the right track?

Background: Hip fractures are a public health problem, leading to hospitalization, long-term rehabilitation, reduced quality of life, large healthcare expenses, and a high 1-year mortality. Especially older adults are at greater risk of fractures than the general population, due to the combination of an increased fall risk and osteoporosis. The aim of this study was to determine time trends in numbers and incidence rates of hip fracture-related hospitalizations and admission duration in the older Dutch population.

Surviving a site audit: tips for good clinical practice in an implant trial.

The number of clinical trials involving implants for trauma and orthopedic surgery is increasing. The International Conference on Harmonization-Good Clinical Practice (ICH-GCP) guideline has been developed in order to assure that the rights, safety, and well-being of trial subjects (i.e.
