INTRODUCTION: Knee osteoarthritis (KOA) is a common, disabling and costly medical condition. The patellofemoral joint is a critical source of pain in individuals with KOA, and coexistence of patellofemoral osteoarthritis (PFOA) and tibiofemoral osteoarthritis (TFOA) is sometimes observed. The identification of subgroups with PFOA and customised interventions to correct underlying pathomechanics is beneficial for individuals with KOA. This study aims to evaluate whether a clinic-based patella mobilisation therapy (PMT) leads to significant improvement in pain, physical function and quality of life of individuals with KOA...

A 76-year-old male presented for reverse total shoulder arthroplasty (TSA) in the beach chair position. A preoperative interscalene nerve catheter was placed under direct ultrasound-guidance utilizing a posterior in-plane approach. On POD 2, the catheter was removed. Three weeks postoperatively, the patient reported worsening dyspnea with a subsequent chest X-ray demonstrating an elevated right hemidiaphragm. Pulmonary function testing revealed worsening deficit from presurgical values consistent with phrenic nerve palsy...

Allowing persons to make an informed choice about their participation in research is a pre-eminent ethical and legal requirement. Almost universally, this requirement has been addressed through the provision of written patient information sheets and consent forms. Researchers and others have raised concerns about the extent to which such forms-particularly given their frequent lengthiness and complexity-provide participants with the tools and knowledge necessary for autonomous decision-making. Concerns are especially pronounced for certain participant groups, such as persons with low literacy and Indigenous persons...

BACKGROUND: As length of stay decreases for total joint arthroplasty, much of the patient preparation and teaching previously done in the hospital must be performed before surgery. However, the most effective form of preparation is unknown. This randomized trial evaluated the effect of a one-time, one-on-one preoperative physical therapy education session coupled with a web-based microsite (preopPTEd) on patients' readiness to discharge from physical therapy (PT), length of hospital stay, and patient-reported functional outcomes after total joint arthroplasty...

On November 21, 2017, Professor Julio R. Villanueva died in Salamanca. Born on April 27, 1928 in Villamayor, council of Piloña (Asturias), he lived almost to the age of 90. His was an accomplished life, full of endeavors and exciting works in the world of research and teaching, which earned him very broad recognition both in Spain and the international arena. Villanueva was undoubtedly the driving force of Fundamental Microbiology in Spain. His early steps came at a time when experimental biology was arriving at an important new age, using microbial systems for experimentation that lead to general conclusions about all living beings...

This study compared the effects of a 4-week supervised (SUP) and unsupervised (UNSUP) resistance training programme followed by 12 weeks of detraining (DET). Thirty-six healthy aging adults (age: 53.6 ± 3.6 years; body mass index: 28.3 ± 5.1 kg/m) were randomly allocated to a SUP group (n = 17) or an UNSUP group (n = 19). Participants completed three training sessions per week using resistance bands and body weight movements. Measures of physical performance were administered at baseline, at the end of the training programme, and after the DET period...

Triterpene synthases, also known as 2,3-oxidosqualene cyclases (OSCs), synthesize diverse triterpene skeletons that form the basis of an array of functionally divergent steroids and triterpenoids. Tetracyclic and pentacyclic triterpene skeletons are synthesized via protosteryl and dammarenyl cations, respectively. The mechanism of conversion between two scaffolds is not well understood. Here, we report a promiscuous OSC from rice (Oryza sativa) (OsOS) that synthesizes a novel pentacyclic triterpene orysatinol as its main product...

The first step from the neuropsychology in Argentina was in 1883 with the thesis of Antonio Piñeiro about the brain localization of the language and vision disorders, only few years after Broca. The aim of this work has been to describe the development of the neuropsychology in Argentina and its relation with the psychology, neurology and psychiatry. The first period was into the neurology with its French school in?uence. In 1907, Jose Ingeniero published in French his book about "amusia", Cristofredo Jakob the "folia neurobiologica" where he described the organization of the human brain, Vicente Dimitri in 1933 his book "aphasia" and Bernardo de Quiros in 1959 his works about dyslexia...

Traditionally, periodontal hand instruments are honed or sharpened during patient care as they dull easily during contact with enamel, calculus and cementum. This approach is taught in dental and hygiene schools around the world and remains the standard of care. Recently, some professional organizations have questioned whether this practice should be abandoned because of safety issues. Questions have been raised whether sharpening stones can be properly sterilized and whether the sharpening of contaminated instruments poses a health hazard for the provider...

Myelomeningocele (MMC) is a congenital malformation that occurs in the embryonic period, characterized by failure in closure of the caudal portion of the neural tube during central nervous system formation. Alterations and complications can be associated with this condition, such as hydrocephalus, neurogenic bladder, orthopedic problems, and motor and cognitive impairment. This patients with MMC also have predisposition to develop latex allergy and high caries risk and activity due to deficient oral hygiene, fermentable carbon hydrate-rich diet and prolonged use of sugar-containing oral medications...

This paper presents a debate in which the authors participated at the World Psychiatric Association conference in Cape Town, South Africa in November 2016. Professor van Staden acted as chair and here, as at the debate, provides a rationale for debating a topic that many of those involved in mental health believe to be decided. The discussion that ensued demonstrated, however, that while the arguments have moved on they have not ceased. Who won? Well that depends how you look at it. A few in the audience shifted position towards the motion but the majority remained opposed...

We present the case of a 72-year-old woman diagnosed with rheumatic fever at the age of 6. In 1972, she was diagnosed with mitral valve insufficiency and mitral valve stenosis, then in 1974, a decision was made to perform mitral valve replacement surgery with a 32-mm Braunwald-Cutter ball cage prosthesis. An echocardiogram performed in 2014 revealed normal biventricular systolic function, mechanical prosthesis in mitral position with maximum speed of 1.9 m/s, maximum gradient of 15 mmHg, mean gradient of 6 mmHg, severe tricuspid valve insufficiency, inferior vena cava measuring 15 mm with more than 50% collapse and pulmonary artery systolic pressure of 40 mmHg...
