Is hybrid fixation in revision TKA using LCCK prostheses reliable?

Introduction: The optimal technique for component fixation in revision total knee arthroplasty (rTKA) remains controversial: full cementation (FC) versus hybrid fixation (HF), which involves press-fit stem with cement fixation in the metaphyseal and epiphyseal zones. Previous series have either demonstrated the superiority of one or the other of these techniques or their equivalence. However, few studies have compared these 2 methods for rTKA using the Legacy® Constrained Condylar Knee (LCCK) prosthesis (Zimmer, Warsaw, Indiana, USA).

Apathetic hyperthyroidism in an elderly patient presenting with psychomotor retardation.

Hyperthyroidism in the elderly population is often associated with atypical, blunted, or nonspecific signs and symptoms, also known as apathetic hyperthyroidism (AH). The absence of the classical hyperkinetic clinical presentation can be confused with the normal aging process, or other diseases, and often leads to misdiagnosis, delayed treatment, and negative outcomes for elderly patients. We provide a case study of an elderly patient to illustrate the atypical presentation of AH.

Second victim phenomenon: Is 'just culture' a reality? An integrative review.

Background: Despite rigorous and multiple attempts to establish a culture of patient safety and a goal to decrease incidence of patient deaths in the health care, estimations of preventable mortality due to medical errors varied widely from 44,000 to 250,000 in hospital settings. This magnitude of medical errors establishes patient safety as being at the forefront of public concerns, healthcare practice and research. In addition to the potential negative impact on patients and the healthcare system, medical errors evoke intense psychological responses in health care providers' responses that threaten their personal and professional selves, and their ability to deliver high quality patient care.

Physiological stress markers during breath-hold diving and SCUBA diving.

This study investigated the sources of physiological stress in diving by comparing SCUBA dives (stressors: hydrostatic pressure, cold, and hyperoxia), apneic dives (hydrostatic pressure, cold, physical activity, hypoxia), and dry static apnea (hypoxia only). We hypothesized that despite the hypoxia induces by a long static apnea, it would be less stressful than SCUBA dive or apneic dives since the latter combined high pressure, physical activity, and cold exposure. Blood samples were collected from 12SCUBA and 12 apnea divers before and after dives.

Exploring the experience of nurse practitioners who have committed medical errors: A phenomenological approach.

Background And Purpose: To explore the experience of committing medical error from the perspective of nurse practitioners (NPs). Overall, the purpose of the study is to discern NPs' behaviors, perceptions, and coping mechanisms in response to having made a medical error.

Methods: Qualitative research based on two face-to-face audio-recorded semistructured interviews with 10 NPs who had made medical errors in practice.
