Purpose: The purpose of this study was to investigate the perspectives program directors CAPTE accredited physical therapist assistant (PTA) educational programs on clinical reasoning (CR) in PTA students and applicability Integrated Clinical Education Theory (ICET) through exploratory research. Methods: Participants completed a survey that collected information about demographics directors’ qu...

Primary tracheal amyloidosis (PTA) can lead to airway obstructions, and patients with severe PTA should undergo bronchoscopic interventions in order to maintain airway patency. Focal airway involvements with amyloidosis can only be treated with mechanical dilatation. However, the PTA with diffused airway involvements and concomitant cartilage destructions requires stent placement. Limited infor...

The EutD protein of Salmonella enterica is homologous to the catalytic domain of the phosphotransacetylase (Pta) enzyme. The Pta-like activity level of the EutD enzyme compared favorably to that of other Pta enzymes. High-pressure liquid chromatography and mass spectrometry verified that acetyl-coenzyme A was the product of the reaction. The EutD protein restored growth of an S. enterica pta st...

OBJECTIVES To determine differences between PTA and conventional medical treatment in treadmill distance until onset of claudication, treadmill maximum walking distance, patient reported maximum walking distance, ankle brachial pressure index (ABPI), quality of life (Nottingham Health Profile, NHP) and Duplex measured extent of occlusive disease. DESIGN Randomised controlled clinical trial. ...

Objective To assess changes in the characteristics of peritonsillar abscess (PTA). Methods A retrospective cohort study. Data obtained from medical records of patients diagnosed as having a peritonsillar abscess that were treated in a secondary urban medical center over a ten-year period (1998-2007). Results 427 patients, within ages of 3 to 91 years (average 31.6, SD 15.2, median 30) were enro...

By W. Angus Muir and Oscar D. Ratnoff P LASMA TH ROM BOPLASTIN antecedent (PTA, Factor X I) deficiency is an inherited disorder of blood coagulation characterized by a defect of the intrinsic pathway of thrombin formation and a mild to moderate bleeding tendency. Since the original description by Rosenthal, Dreskin, and Rosenthal,’ it has been reported in this country and in Europe to occur wit...

PURPOSE Patellar tendon abnormality (PTA) on diagnostic imaging is part of the diagnostic criteria for patellar tendinopathy. PTA and altered landing strategies are primary risk factors that increase the likelihood of asymptomatic athletes developing patellar tendinopathy. Therefore, the aim of this study was to examine the risk factors that are predictors of the presence and severity of a PTA ...

Post-traumatic arthritis (PTA) develops after an acute direct trauma to the joints. PTA causes about 12% of all osteoarthritis cases, and a history of physical trauma may also be found in patients with chronic inflammatory arthritis. Symptoms include swelling, synovial effusion, pain and sometimes intra-articular bleeding. Usually, PTA recoveries spontaneously, but the persistence of symptoms a...

BACKGROUND The effectiveness of percutaneous transluminal angioplasty (PTA) in renal artery stenosis (RAS) associated with neurofibromatosis type 1 (NF1) has not been established. A review of the literature revealed 14 studies, mainly case reports, of which a total of 16 patients had been treated with PTA, all prior to any surgery being undertaken. METHODS A retrospective case review of 10 ch...

Genomic evaluations are calculated using deregressed predicted transmitting abilities (PTA) from traditional evaluations to estimate effects of single nucleotide polymorphisms. The direct genomic value (sum of an animal's marker effects) should be consistent with traditional PTA, which is the case for bulls. However, traditional PTA of yield traits (milk, fat, and protein) for genotyped cows ar...
