BACKGROUND: Postoperative adverse events are known to increase length of stay and cost. However, research on how adverse events affect patient flow and operational performance has been relatively limited to date. Moreover, there is paucity of studies on the use of simulation in understanding the effect of complications on care processes and resources. In hospitals with scarcity of resources, postoperative complications can exert a substantial influence on hospital throughputs. METHODS: This paper describes an evaluation method for assessing the effect of complications on patient flow within a cardiac surgical department...

BACKGROUND: Providing nursing teams with feedback on quality measurements is used as a quality improvement instrument in healthcare organizations worldwide. Previous research indicated contradictory results regarding the effect of such feedback on both nurses' well-being and performance. OBJECTIVES: Building on the Job Demands-Resources model this study explores: (1) whether and how nurses' perceptions of feedback on quality measurements (as a burdening job demand or rather as an intrinsically or extrinsically motivating job resource) are respectively related to nurses' well-being and performance; and (2) whether and how team reflection influences nurses' perceptions...

The use of tissue-engineered bone constructs is an appealing strategy to overcome drawbacks of autografts for the treatment of massive bone defects. As a model organism, the mouse has already been widely used in bone-related research. Large diaphyseal bone defect models in mice, however, are sparse and often use bone fixation which fills the bone marrow cavity and does not provide optimal mechanical stability. The objectives of the current study were to develop a critical-size, segmental, femoral defect in nude mice...

OBJECTIVES: The annual incidence of hip fracture is 620 000 in the European Union. The cost of this clinical problem has been estimated at 1.75 million disability-adjusted life years lost, equating to 1.4% of the total healthcare burden in established market economies. Recent guidance from The National Institute for Health and Clinical Excellence (NICE) states that research into the clinical and cost effectiveness of total hip arthroplasty (THA) as a treatment for hip fracture is a priority...

The diagnosis of ankle osteoarthritis (OA) is increasing as a result of advancements in non-invasive imaging modalities such as magnetic resonance imaging, improved arthroscopic surgical technology and heightened awareness among clinicians. Unlike OA of the knee, primary or age-related ankle OA is rare, with the majority of ankle OA classified as post-traumatic (PTOA). Ankle trauma, more specifically ankle sprain, is the single most common athletic injury, and no effective therapies are available to prevent or slow progression of PTOA...

BACKGROUND: Liver metastasis is common in patients with oesophageal cancer. The effect of operative intervention for post-operative solitary liver metastasis from oesophageal squamous cell carcinoma (ESCC) has not previously been examined. This research was to compare the effect of surgery and non-surgical therapy in patients with post-operative solitary liver metastasis from ESCC. METHODS: We retrospectively analysed the clinical data of 69 consecutive patients with solitary hepatic metastasis who had undergone oesophagectomy for ESCC and were subsequently referred to the First Affiliated Hospital of Zhengzhou University from January 2005 to December 2013...

A trophic ulcer is a pressure ulcer caused by external trauma to a part of the body that is compromised due to disease, vascular insufficiency, or loss of afferent nerve fibers. Spinal dysraphism (ie, neural tube defects [NTD]) such as meningomyelocele is a risk factor for developing these ulcers in adults and pediatric patients. Information regarding the occurrence of trophic ulcers in pediatric patients with NTD is lacking. A review of the English-language literature on skin/neuropathic ulcers in patients with NTDs, irrespective of study design, published between 1975 and 2014, was undertaken using the PubMed database...

BACKGROUND: Over 300 million patients undergo surgery worldwide each year. Postoperative morbidity - particularly respiratory complications - are most frequent and severe among high-risk patients undergoing major abdominal surgery. However, standard treatments, like physiotherapy or supplemental oxygen, often fail to prevent these. Preliminary research suggests that prophylactic continuous positive airways pressure (CPAP) can reduce the risk of postoperative respiratory complications...

OBJECTIVE: A novel nerve cuff electrode with embedded magnets was fabricated and developed. In this study, a pair of magnets was fully embedded and encapsulated in a liquid crystal polymer (LCP) substrate to utilize magnetic force in order to replace the conventional installing techniques of cuff electrodes. In vitro and in vivo experiments were conducted to evaluate the feasibility of the magnet-embedded nerve cuff electrode (MENCE). Lastly, several issues pertaining to the MENCE such as the cuff-to-nerve diameter ratio, the force of the magnets, and possible concerns were discussed in the discussion section...

Bariatric surgery is the most robust treatment for extreme obesity. The impact of preoperative medical weight management sessions designed, in theory, with the primary goal of promoting preoperative weight loss, is unclear. This paper reviews studies that have investigated the relationship between preoperative weight loss and bariatric surgical outcomes, both with respect to postoperative weight loss and complications. We conclude that the most robust of preoperative interventions has not been implemented or evaluated in a manner which would conclusively assess the value of this element of care...

The potential advantages of contemporary MoM THA implants include less volumetric wear with subsequent reduction of polyethylene wear-induced osteolysis and greater component stability with use of large-diameter femoral heads. However, there have been concerns regarding significantly elevated revision rates in MoM THA due to MoM-related complications such as adverse local tissue reaction (pseudotumour) formation. The increased failure rate in MoM hip arthroplasty is associated with the generation of biologically active, nanometer sized metal particles from the MoM bearing surfaces and taper junctions, which result in the development of a localized, adverse periprosthetic soft tissue response...

BACKGROUND: Giant Cell Tumor is considered a benign, local and aggressive tumor. Although considered a benign bone tumor, it is still the subject of discussion and research because of the associated local bone destruction, as well as high rates of recurrence and distant metastases. Options are being developed for both surgical techniques and adjuvant therapies. AIMS: The present study evaluated the administration of cryotherapy via a pressurized-spray technique in giant cell tumors of the bone...

Hyperglycaemia following surgical and anaesthetic stress is a well-established entity which might have undesirable clinical consequences in known diabetics. We encountered a rare event where an undiagnosed diabetic patient developed ketoacidosis in the immediate post-operative period which was her initial presenting symptom of deranged glucoregulation. Presumably, the stress induced by surgery and anaesthesia lead to the genesis of this event. We discuss the management of this case. In addition, we highlight the importance of glycosylated haemoglobin as a subject of future research in identifying such "at risk" patients and for stratifying the risk of hyperglycaemic complications in perioperative settings...

Importance: Intermittent claudication (IC) is the most common presentation of infrainguinal peripheral artery disease. Both medical and revascularization interventions for IC aim to increase walking comfort and distance, but there is inconclusive evidence of the comparative benefit of revascularization given the possible risk of limb loss. Objective: To compare the effectiveness of a medical (walking program, smoking cessation counseling, and medications) vs revascularization (endovascular or surgical) intervention for IC in the community, focusing on outcomes of greatest importance to patients...
