Purpose: The purposes were to assess the functional recovery of those who survived a prolonged intensive care unit (ICU) stay by reporting the proportion who were able to ambulate independently at hospital discharge and also to examine if the time duration between admission and when the patient first stood impacted on their capacity to ambulate at discharge.

Materials And Methods: A retrospective review was conducted of medical records of ICU patients in 2007 to 2008, who were mechanically ventilated for 168 hours or more, and survived their acute care stay. Main outcome measures were (1) ambulation status before admission and at time of hospital discharge and (2) time between admission to the ICU and when the patient first stood.

Because cancer care requires a multifaceted approach, providing useful and timely information to people with colorectal cancer may be fragmented and inconsistent. Our interest was in examining what has and has not captured the attention of researchers speaking to the information needs of people with colorectal cancer. We followed Arksey and O'Malley's framework for the methodology of scoping review.

The aim of hyperinflation in the ventilated intensive care unit patient is to increase oxygenation, reverse lung collapse and clear sputum. The efficacy and consistency of manual hyperventilation is well supported in the literature, but there is limited published evidence supporting hyperventilation utilising a ventilator. Despite this, a recent survey established that almost 40% of Australian tertiary intensive care units utilise ventilator hyperinflation.

Painful patellar crepitus is a potential complication in up to 14% of patients following posterior-stabilized (PS) total knee arthroplasty (TKA). A recent clinical study identified influential patient and surgical variables by comparing a group of crepitus patients with controls matched for age, sex, and body mass index. The purpose of our study was to evaluate effects of variables identified as significant in the clinical study, including patellar ligament length, femoral component flexion, patellar button size, and position of the joint line, on contact between the quadriceps tendon and the PS femoral component.

Background: Falling among adults in acute care is an important problem with falls rates in tertiary hospitals ranging from 2% to 5%. Factors that increase the risk of falling, such as advanced age, altered mental status, medications that act on the central nervous system and poor mobility, often characterise individuals who survive a prolonged intensive care unit (ICU) admission.

Purpose: To measure the incidence of falls and describe the characteristics of fallers among intensive care survivors.

Purpose: Malnutrition and psychological distress are associated with poorer outcomes following treatment for colorectal cancer. Screening for issues such as malnutrition, depression, and anxiety is being adopted in some oncology settings, but its effectiveness or the relationship between these risk factors in this population are not well understood.

Methods: A retrospective chart review was conducted of 836 health assessment forms provided to colorectal cancer patients referred to an outpatient oncology clinic.

Although use of modular femoral components in revision total hip arthroplasty (THA) is widely accepted, many still question the need for modular versatility in primary THA. This study examined a large cohort of primary THA patients implanted with a modular S-ROM femoral component (DePuy Orthopaedics, Warsaw, Indiana) to determine the percentage of hips in which the surgeon changed version of the femoral component to increase the intraoperative stability of the THA construct and/or to maximize hip range of motion without impingement.In a group of 1000 routine, primary THAs, femoral component version was changed in 479 hips (47.

We designed and built a novel, miniature gas chromatograph (mGC) to use exhaled breath to estimate blood ethanol concentrations that may offer GC quality sensitivity and specificity, but with portability, reduced size, and decreased cost. We hypothesized that the mGC would accurately estimate the serum ethanol concentration using exhaled breath. Human subjects (n = 8) were dosed with ethanol employing the Widmark criteria, targeting a blood concentration of 0.

Objective: To determine if 1) angularly stable devices created by compressing ("locking") proximal locking screws to intramedullary nails using end caps or compression screws or 2) increasing the number of proximal screws from two to three increases the stiffness of intramedullary constructs that stabilize proximal third tibia fractures in a nonosteopenic bone model.

Methods: Four proximal locking screw configurations were examined in a synthetic composite tibia model with a 2-cm gap simulating a comminuted proximal third tibia fracture with no bony contact: 1) two proximal screws not compressed to the nail; 2) one of two proximal screws compressed to the nail; 3) two proximal screws compressed to the nail; and 4) three proximal screws with only the most proximal screw compressed to the nail. An 11-mm tibial nail with two distal locking screws was used.

Background: Total knee arthroplasty (TKA) in patients with skeletal dysplasias is particularly challenging as a result of the anatomic variances and substantial bony deformities. Little has been written regarding technical considerations that should be made when performing TKA in skeletal dysplasia.

Questions/purposes: We describe special operative considerations that must be made when performing TKA on patients with skeletal dysplasia, including implant selection and ligamentous balancing.
