#1
Theodore W Kurtz, Stephen E DiCarlo, R Curtis Morris
The term "abnormal pressure natriuresis" refers to a subnormal effect of a given level of blood pressure (BP) on sodium excretion. It is widely believed that abnormal pressure natriuresis causes an initial increase in BP to be sustained. We refer to this view as the "pressure natriuresis theory of chronic hypertension." The proponents of the theory contend that all forms of chronic hypertension are sustained by abnormal pressure natriuresis, irrespective of how hypertension is initiated. This theory would appear to follow from "the three laws of long-term arterial pressure regulation" stated by Guyton and Coleman more than 3 decades ago...

The articulating components of artificial joints consist mainly of metals, ceramics, or polymers. Resulting abrasive wear particles can promote osteolysis and aseptic loosening of the endo-prosthetic implants. Ultra-high-molecular-weight-polyethylene is the material used most for bearing couples in total hip replacement. In the present study, three types of polyethylene (PE) liners varying in material composition, i.e., (1) conventional PE (C-PE), (2) sequentially cross-linked PE (SX-PE), (3) cross-linked PE blended with vitamin E (EX-PE) articulating with two types of femoral heads were used...

Salivation after stroke (sialorrhea, hypersalivation, ptyalism) can be caused by the overproduction or a lack of utilization of saliva. Patients after stroke often have sialorrhea as a result of dysphagia. Neurogenic dysphagia in acute period after stroke occurs in 25-65% of patients. The mortality rate among people with post-stroke dysphagia and tube feeding ranges from 20 to 24%. Patients who suffering from profuse salivation have difficulties with articulation and swallowing, bad breath, irritation and maceration of perioral area, contamination of clothing and bed linen...

BACKGROUND: Accredited exercise physiologists (AEPs) are emerging as essential members of allied health in the management of non-communicable chronic diseases. People diagnosed with severe mental illness (SMI) are at greater risk of cardiovascular diseases. Secure extended care units (SECUs) provide treatment, supervision and support for people with SMI whose needs cannot be met adequately in the community. However, the role of AEPs in SECUs has not been described. AIM: Describe the processes and outcomes of adding an AEP to a new model of care at a SECU...

BACKGROUND: Severe pain and chronic pain have a high impact on individuals and society. Body location of pain is important with regard to perception, articulation, and underlying biological, mental or social causes of pain. METHODS: A cross-sectional survey was performed in the general Austrian population with 15,474 personally interviewed subjects aged 15 years and older. RESULTS: The 1‑year period prevalence of severe pain in any body site was 38...

Facial nerve paralysis can occur due to infection, inflammation, trauma, surgery, and tumors. It leads to facial asymmetry, impaired oral competence, articulation deficits, and psychological problems. Treatment options include physical therapy, static slings, nerve and muscle transfers, blepharoplasty, brow lift, and chemodenervation with botulinum toxin. We report the case of a 66-year-old Caucasian female with permanent facial paralysis following middle ear surgery. The facial asymmetry was treated successfully with botulinum toxin A injection, hyaluronic acid dermal filler injection, and a thread-lift procedure...

Austyn Snowden, Iain Telfer
Chaplains are employed by health organizations around the world to support patients in recognizing and addressing their spiritual needs. There is currently no generalizable measure of the impact of these interventions and so the clinical and strategic worth of chaplaincy is difficult to articulate. This article introduces the Scottish PROM, an original five-item patient reported outcome measure constructed specifically to address this gap. It describes the validation process from its conceptual grounding in the spiritual care literature through face and content validity cycles...

PROBLEM: Educators face many challenges in teaching professionalism. Despite attempts to define professionalism, it remains abstract for students and often not fully appreciated until they are in clinic. Without a way to make it personally relevant, students will likely be less motivated to learn. INTERVENTION: We used student-generated word clouds to facilitate reflection and discussions, thereby helping students make their perceptions of professionalism more explicit...

Anselma G Hartley, R Michael Furr
We present a novel profile-based framework for understanding factorial similarity in the context of exploratory factor analysis in general, and for understanding the congruence coefficient (a commonly used index of factor similarity) specifically. First, we introduce the profile-based framework articulating factorial similarity in terms of 3 intuitive components: general saturation similarity, differential saturation similarity, and configural similarity. We then articulate the congruence coefficient in terms of these components, along with 2 additional profile-based components, and we explain how these components resolve ambiguities that can be-and are-found when using the congruence coefficient...

INTRODUCTION: Pseudotumor is not an uncommon complication after total hip arthroplasty (THA). This can occur in relationship to different bearing surfaces of head and liner ranging from soft to hard articulation. There is wide spectrum of presentation from asymptomatic to implant failure. CASE REPORT: We report a case of pseudotumor formation with acetabular cup aseptic loosening after revision ceramic on metal hip arthroplasty. The patient underwent pseudotumor excision and re-revision complex arthroplasty procedure using trabecular metal shell and buttress with ceramic on polyethylene THA...

We investigated the effects of an auditory match-to-sample protocol on three preschoolers' accurate echoics to 100 English words and advanced listener responses. The protocol was presented by using an iPad app Sounds the same: an app to target listening and speaking clearly. We used a combination of a multiple probe design (for echoic responses) and a delayed multiple probe design (for advanced listener literacy responses) with a time-lagged baseline across participants to test the effectiveness of the protocol...

This study was performed to investigate the safety and efficacy of the intra-articular infusion of ex vivo expanded autologous bone marrow-derived mesenchymal stem cells (BM-MSC) to a cohort of patients with articular cartilage defects in the hip. The above rationale is sustained by the notion that MSCs express a chondrocyte differential potential and produce extracellular matrix molecules as well as regulatory signals, that may well contribute to cure the function of the damaged hip joint. A cohort of 10 patients with functional and radiological evidences of hip osteoarthritis, either in one or both legs, was included in the study...

BACKGROUND: Scapholunate ligament injury is a commonly occurring carpal ligament injury. Pathology associated with scapholunate ligament injury depends on several factors such as the time after injury, type of injury (instability) and the development of osteoarthritis. The aim of this study was to investigate and compare contact mechanics in the lunocapitate and scaphocapitate joints in the normal, injured (scapholunate dissociation) and repaired (postoperative) wrist. METHODS: Four human subjects with scapholunate ligament dissociation participated in this study...

BACKGROUND: Pain is a universal and complex phenomenon that is personal, subjective and specific. Despite growing knowledge in pediatric pain, management of children's pain remains sub-optimal and is linked to negative behavioral and physiological consequences later in life. As there is no synthesis of these studies, it was timely to undertake a systematic review. OBJECTIVES: To identify, evaluate and synthesize the existing qualitative evidence on children's experiences of acute pain, including pain management, within a healthcare facility...

REVIEW
Michele Biasutti
Improvisation is an articulated multidimensional activity based on an extemporaneous creative performance. Practicing improvisation, participants expand sophisticated skills such as sensory and perceptual encoding, memory storage and recall, motor control, and performance monitoring. Improvisation abilities have been developed following several methodologies mainly with a product-oriented perspective. A model framed under the socio-cultural theory of learning for designing didactic activities on processes instead of outcomes is presented in the current paper...

PATIENT: A 60-year-old man presented for refabrication of his maxillary complete denture. In this case, a digital process was chosen to replace the ill-fitted complete maxillary denture. A specialized scan retractor was used to retract the mobile tissues of the lips, cheeks and vestibule while taking a digital impression. The interocclusal record obtained in the patient's mouth was scanned in order to digitally register the occlusal vertical dimension. The denture base and teeth were designed on virtual models that were mounted at the occlusal vertical dimension, and were made using CAD/CAM technology...

Well preserved thoracic vertebrae of Neandertals are rare. However, such fossils are important as their three-dimensional (3D) spatial configuration can contribute to the understanding of the size and shape of the thoracic spine and the entire thorax. This is because the vertebral body and transverse processes provide the articulation and attachment sites for the ribs. Dorsal orientation of the transverse processes relative to the vertebral body also rotates the attached ribs in a way that could affect thorax width...
