RESUMO
Severe musculoskeletal disease characterized by marked joint laxity was the cause of euthanasia in two wild juvenile American black bears (Ursus americanus) admitted to a rehabilitation facility in eastern Tennessee in 2023. Previously, almost all reported musculoskeletal diseases in this population were of traumatic etiology, even in malnourished yearlings. Case 1 was an orphaned 11-month-old male cub exhibiting disproportionate dwarfism, progressive immobility, and joint laxity. Necropsy findings suggested either chondrodysplasia or rickets, and imaging findings supported a skeletal dysplasia. Case 2 was a 14-month-old emaciated male yearling exhibiting joint laxity and immobility. Necropsy findings showed osteoporosis and serous atrophy of fat, and imaging findings were inconsistent with a skeletal dysplasia. Both cases were clinically inconsistent with rickets based on normal calcium, phosphorous, and parathyroid hormone concentrations; however, Case 1 had hypovitaminosis D (9 nmol/L) compared to healthy juvenile black bears. We hypothesize that Case 1 had a genetic chondrodysplasia while the osteoporosis of Case 2 was due to chronic malnutrition. The goal of this case report is to inform wildlife agencies and facilities to monitor for similar, non-trauma-related debilitating musculoskeletal disease in free-ranging bears and evaluate cases that allow us to further understand the disease processes involved.
RESUMO
The pandemic has inevitably led to disruptions in the provision of health services for all those patients not affected by COVID-19. At the same time, we have observed differences among health services in their ability to maintain their activities in the face of shocks: while some health services were largely able to ensure core functions, other suffered delays in prevention, acute care, and rehabilitation. In this paper, we explore the effect of regional health policies in terms of governance, workforce, and health service delivery on the ability to maintain oncological services during the COVID-19 pandemic to assess the resilience of the system. The study is based on secondary data collected on the 21 Italian regional health services during the first wave of the pandemic. We discuss the theoretical and practical implications of providing health services with specific characteristics pertaining to governance, workforce, and health service delivery to support the resilience of regional health policies during a crisis or shock.
RESUMO
BACKGROUND: Within many advanced healthcare systems, patient advocacy associations are gaining a more relevant role in healthcare policy decisions. These associations provide help, representation, and voice to patients and citizens. However, although their role is important, a paucity of research exists analyzing their foundation dynamics, including their organizational decision, from a managerial perspective. To fill this knowledge gap, we formulated two research questions to investigate the motivations underlying the foundation of patient advocacy associations and the institutional pressures influencing the changes that have occurred in these associations throughout their evolution. METHODS: Using a semi-structured questionnaire developed as part of a larger research project, we collected data about 31 patient advocacy associations operating within the Italian National Health Service. We employed qualitative analysis to examine the associations' birth and evolution as well as the motivations and influences driving change within the sampled organizations. RESULTS: Questionnaire responses provided information about the patient advocacy associations' histories and highlighted their close links with the Italian National Health Service. Our results indicated the motivations for the associations' establishment could be grouped into five categories: support at the system level, patient protection and support, actions to increase awareness, actions for improving patients' health and quality of life, and dissemination of knowledge. We also identified the frequency and nature of the changes within the associations and explored the institutional pressures that influenced these organizational changes. CONCLUSIONS: The results can be interpreted considering the organizational theories that focus on organizations' establishment decisions and how external pressures impact organizations' dynamics and evolution.
RESUMO
The integrity of the tympanic membrane is an important factor when deciding treatment and therapeutic recommendations for dogs with ear disease; however, otoscopic examination may be difficult to perform due to features of external ear canal disease or patient compliance. CT is useful for the evaluation of middle ear disease, including cases in which middle ear disease is detected incidentally. The tympanic membrane is detectable using CT, but anecdotally, apparent focal defects or discontinuities of the tympanic membrane are often seen in patients with and without ear disease. The purpose of this prospective, observer agreement study was to determine if perforations of the tympanic membrane are reliably detectable on CT. Fifteen cadaver dogs underwent CT and video otoscopy to verify the integrity of each tympanic membrane. Cadavers were randomly assigned to have the tympanic membranes left intact or to undergo a myringotomy on either the left, the right, or both sides. CT was performed immediately following the myringotomies. Four blinded evaluators evaluated the pre- and post-myringotomy scans for a total of 30 scans (60 tympanic membranes). Average accuracy was low (44%), and interobserver agreement for all four evaluators was fair. Although the tympanic membrane is visible on CT, perforations of the tympanic membrane are unlikely to be accurately detected or excluded. The appearance of an intact tympanic membrane or defect in the membrane on CT should not be used as criteria to guide clinical treatment recommendations based on this cadaver model.
