Introduction In general surgery, open abdomen treatment (OAT) is used to treat abdominal compartment syndrome (ACS) and sepsis, often after a primary surgical procedure associated with complications. The results achieved in this patient population may depend on factors that are yet unknown. This study evaluates independent patient-related prognostic factors after OAT. Methods 38 clinical parameters and survival data of 165 consecutive general surgery patients after OAT were entered into a prospective database according to a defined algorithm in order to analyse the underlying surgical pathology, predictors of survival and important aspects of OAT-related morbidity...

Background Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal cancers with high risk of relapse even after curative-intended resection. There are no evidence-based recommendations for surveillance in actual guidelines. Given this situation and as a basis for prospective studies, we wanted to determine the current practice of surveillance after pancreatic cancer resection in German institutions. Methods A web-based questionnaire was sent in 2015 to 300 German institutions (hospitals, outpatient clinics, and private practices) experienced in the care of patients with PDAC...

The incidence of lateral patella dislocations is high, particularly in young females. Beside traumatic cases, many patients present with specific anatomical factors that predispose to lateral patella dislocations (torsional abnormalities of the femur or the tibia, trochlea dysplasia, patella alta, etc). It is of utmost importance to correct those pathologic factors during concomitant procedures as isolated reconstructions of the medial patellofemoral ligament would fail in the presence of severe anatomic risk factors...

Dog bite injuries are common and the head and neck is most frequently involved in pediatric patients. In severe cases, the combination of crushing, tearing, and puncturing can result in scalp avulsion. Currently, microsurgical replantation of the avulsed scalp remains the gold standard but may not always be possible. The authors present their treatment algorithm with 2 patient examples. In Patient 1, the scalp was deemed unsuitable for replantation due to extensive soft tissue injury; in Patient 2, the scalp was not available on presentation...

Articular cartilage injury can result in chondrocyte loss and diminishment of specialised extracellular matrix, which can progress to an osteoarthritic (OA) phenotype. Stem cells have emerged as a favourable approach for articular cartilage regeneration. Identification of miRNAs which influence stem cell fate offers new approaches for application of miRNAs to regenerate articular cartilage. Skeletal stem cells (SSCs) isolated from human bone marrow were cultured as high density micromass' using TGF-β3 to induce chondrogenesis...

Despite enormous progress in the field of pain management over the recent years, pain continues to be a highly prevalent medical condition worldwide. In the developing countries, pain is often an undertreated and neglected aspect of treatment. Awareness issues and several misconceptions associated with the use of analgesics, fear of adverse events - particularly with opioids and surgical methods of analgesia - are major factors contributing to suboptimal treatment of pain. Untreated pain, as a consequence, is associated with disability, loss of income, unemployment and considerable mortality; besides contributing majorly to the economic burden on the society and the health care system in general...

In this study, Bayes' theorem was used to determine the probability of a patient having Lyme disease (LD), given a positive test result obtained using commercial test kits in clinically diagnosed patients. In addition, an algorithm was developed to extend the theorem to the two-tier test methodology. Using a disease prevalence of 5%-75% in samples sent for testing by clinicians, evaluated with a C6 peptide enzyme-linked immunosorbent assay (ELISA), the probability of infection given a positive test ranged from 26...

REVIEW
Keith C Meyer, Catherine A Decker
Pulmonary fibrosis is associated with a number of specific forms of interstitial lung disease (ILD) and can lead to progressive decline in lung function, poor quality of life, and, ultimately, early death. Idiopathic pulmonary fibrosis (IPF), the most common fibrotic ILD, affects up to 1 in 200 elderly individuals and has a median survival that ranges from 3 to 5 years following initial diagnosis. IPF has not been shown to respond to immunomodulatory therapies, but recent trials with novel antifibrotic agents have demonstrated lessening of lung function decline over time...

Neurological injuries such as stroke can lead to proprioceptive impairment. For an informed diagnosis, prognosis, and treatment planning, it is essential to be able to distinguish between healthy performance and deficits following the neurological injury. Since there is some evidence that proprioception declines with age and stroke occurs predominantly in the elderly population, it is important to create a healthy reference model in this specific age group. However, most studies investigate age effects by comparing young and elderly subjects and do not provide a model within a target age range...

Performing randomised comparative clinical trials in radiation oncology remains a challenge when new treatment modalities become available. One of the most recent examples is the lack of phase III trials demonstrating the superiority of intensity-modulated radiation therapy in most of its current indications. A new paradigm is developing that consists in the mining of large databases to answer clinical or translational issues. Beyond national databases (such as SEER or NCDB), that often lack the necessary level of details on the population studied or the treatments performed, electronic health records can be used to create detailed phenotypic profiles of any patients...

Most algorithms for type 2 diabetes mellitus (T2DM) do not recommend treatment escalation until glycated haemoglobin (HbA1c) fails to reach the recommended target of 7% (53 mmol/mol) within approximately 3 months on any treatment regimen ('treat to failure'). Clinical inertia and/or poor adherence to therapy contribute to patients not reaching glycaemic targets when managed according to this paradigm. Clinical inertia exists across the entire spectrum of anti-diabetes therapies, although it is most pronounced when initiating and optimizing insulin therapy...

Bi-clustering is a widely used data mining technique for analyzing gene expression data. It simultaneously groups genes and samples of an input gene expression data matrix to discover bi-clusters that relevant samples exhibit similar gene expression profiles over a subset of genes. The discovered bi-clusters bring insights for categorization of cancer subtypes, gene treatments and others. Most existing bi-clustering approaches can only enumerate bi-clusters with constant values. Gene interaction networks can help to understand the pattern of cancer subtypes, but they are rarely integrated with gene expression data for exploring cancer subtypes...

The mainstay for the current treatment of severe aortic stenosis includes surgical aortic valve replacement (SAVR) and transcatheter aortic valve implantation (TAVI). In patients with high operative risk TAVI is established as first line therapy. New data on intermediate and low risk groups demonstrate at least non-inferiority of TAVI against SAVR, and in the near future a consistently rising number of transcatheter procedures may be anticipated. The purpose of this review is to outline the decision making process, hence to illustrate the diagnostic algorithm and to provide criteria for a differentiated approach against the background of recent data...

BACKGROUND: Intrathecal drug delivery is an attractive option to circumvent the blood-brain barrier for pain management through its increased efficacy of pain relief, reduction in adverse side effects, and cost-effectiveness. Unfortunately, there are limited guidelines for physicians to choose infusion or drug pump settings to administer therapeutic doses to specific regions of the spine or the brain. Although empiric trialing of intrathecal drugs is critical to determine the sustained side effects, currently there is no inexpensive in vitro method to guide the selection of spinal drug delivery parameters...
