Background Hummingbirds are frequently presented to California wildlife rehabilitation centers for medical care, accounting for approximately 5% of overall admissions. Age, sex, and reason for admission could impact hummingbird survivability, therefore identification of these factors could help maximize rehabilitation efforts. Methods Mixed-effects logistic regression models were used to identify specific threats to the survival of 6908 hummingbirds (1645 nestlings and 5263 non-nestlings) consisting of five species (Calypte anna, Calypte costa, Selasphorus rufus, Selasphorus sasin, Archilochus alexandri), found in urban settings, and admitted to California wildlife rehabilitation centers over 26 years. Results In total, 36% of birds survived and were transferred to flight cage facilities for further rehabilitation and/or release. Nestlings were more likely to be transferred and/or released compared to adult hummingbirds. After accounting for age, birds rescued in spring and summer were twice as likely to be released compared to birds rescued in the fall. A high number of nestlings were presented to the rehabilitation centers during spring, which coincides with the nesting season for hummingbirds in California, with the lowest number of nestlings presented in fall. Reasons for presentation to rehabilitation centers included several anthropogenic factors such as window collisions (9.6%) and interactions with domesticated animals (12.9%). Survival odds were lower if a hummingbird was rescued in a “torpor-like state” and were higher if rescued for “nest-related” reasons. Evaluation of treatment regimens administered at wildlife rehabilitation centers identified supportive care, including providing commercial nutrient-rich nectar plus solution, to significantly increase hummingbird survivability. Discussion Our results provide evidence of threats to hummingbirds in urban habitats, based on reasons for rescue and presentation to rehabilitation centers. Reasons for hummingbird admissions to three California wildlife rehabilitation centers were anthropogenic in nature (i.e., being associated with domestic animals, window collisions, and found inside a man-made structure) and constituted 25% of total admissions. There was a clear indication that supportive care, such as feeding a commercial nectar solution, and medical treatment significantly increased the odds of survival for rescued hummingbirds.

The NCCN Guidelines for Acute Lymphoblastic Leukemia (ALL) focus on the classification of ALL subtypes based on immunophenotype and cytogenetic/molecular markers; risk assessment and stratification for risk-adapted therapy; treatment strategies for Philadelphia chromosome (Ph)-positive and Ph-negative ALL for both adolescent and young adult and adult patients; and supportive care considerations. Given the complexity of ALL treatment regimens and the required supportive care measures, the NCCN ALL Panel recommends that patients be treated at a specialized cancer center with expertise in the management of ALL This portion of the Guidelines focuses on the management of Ph-positive and Ph-negative ALL in adolescents and young adults, and management in relapsed settings.

The urgency of the issue under study is due to dynamics of the number of children with disabilities in the country and in particular regions. For instance, the total number of disabled children in Russia receiving social pensions between the ages of 0 and 18 was more than 655 thousand, as of January 1, 2018. At the same time, an increase of this indicator is observed constantly. The need to develop scientifically based recommendations for the establishment of rehabilitation centers is due to the fact, that in most cases this assistance is provided in the adapted premises. It is not possible to carry out correctional work effectively. The article’s purpose is to identify factors in the formation of architectural environment of rehabilitation centers for children and adolescents with various disabilities. The systematic method of analyzing the objects in question is the leading approach to studying this problem. Identified factors are divided into external and internal. The external are natural, climatic and anthropogenic factors. Internal include functional and technological, medical and ergonomic, sanitary and hygienic, architectural and stylistic factors. All factors are interrelated. This is reflected in a pilot project of a rehabilitation center for children and adolescents in the Oryol Region. The materials of the article can be useful for architects when designing rehabilitation centers for children and adolescents with various disabilities.

Australasian biodiversity is facing immense challenges with losses of prime habitats and food sources through increased anthropogenic factors such as climate change, bushfires, and habitat modification. Wildlife species are requiring greater conservation intervention supported through numerous wildlife rescue and rehabilitation programmes in this region. It is important to record the physiological stress responses of rescued wildlife and currently available conservation physiology tools can certainly aid the conservation management and rehabilitation of rescued wildlife. In this chapter, we showcase the applications of minimally invasive stress hormone and immune response (haematological blood cell profiling) biomarkers using case studies of rescued koalas (Phascolarctos cinereus) to quantify their physiological stress responses to environmental trauma and disease conditions, and clinical intervention. Applications of these physiological biomarkers can advance our understanding of how wildlife respond towards and cope with environmental challenges and support conservation goals of rescue centres to strengthen wildlife rehabilitation and release back to the wild once the proximate stressors have been eliminated.

Although wildlife rehabilitation relies heavily on volunteers, the characteristics and motivations of such volunteer workers have not been studied. 80 volunteers from three San Francisco Bay Area Rehabilitation Centers, were interviewed about their preferences in working with animals and people, their methods of dealing with grief and failure over animals' deaths, and the onset of their interest in and motives for working in a difficult field. A significant number had owned pets in childhood as well as currently. 40% preferred working only with animals to working with both animals and people. 34% stayed in rehabilitation because they loved and wanted to help animals; 23% enjoyed hands-on nurturing; and the remainder primarily felt they were giving back to Nature a part of what people have taken from it.

Abstract Background.  Identifying factors associated with tuberculosis (TB) deaths will inform efforts to prevent deaths. Methods.  We examined deaths among patients with culture-confirmed TB reported to the California TB Registry during 1994–2008. We calculated the age-adjusted percentage of deaths before and during TB treatment and estimated trends. We constructed multivariable logistic regression models to identify factors associated with death during treatment. Results.  Of 40 125 patients with culture-confirmed TB, 4565 (11%) died: 1146 (25%) died before treatment started, and 3419 (75%) died during treatment. The age-adjusted percentage of patients who died before and during treatment declined from 1994 to 2008 (3.5% to 2%, and 10.4% to 7.2%, respectively, both P < .0001). We identified several risk factors for death that may be addressed with public health efforts: acquired multidrug resistance (adjusted odds ratio [aOR] = 4.67; 95% confidence interval [CI], 2.09–10.45); care in the private sector (aOR = 3.08; 95% CI, 2.75–3.44); and an initial treatment regimen of <3 drugs (aOR = 2.07; 95% CI, 1.63–2.64). We identified other risk factors for death that could be used as markers for intensified diagnostic and treatment processes in hospital: human immunodeficiency virus coinfection; meningeal, peritoneal, and disseminated TB; substance use; and abnormal chest radiograph without cavities. Conclusions.  In California, 1 in 9 TB patients died with a potentially curable disease. Public health departments might prevent deaths in patients with TB by strengthening partnerships with private providers, intensifying diagnostic and treatment processes for patients at risk of death in hospital, optimizing treatment regimens for patients with comorbidities, and preventing the acquisition of drug resistance.

Depredation of birds by domestic cats is hypothesized to be one of many significant sources of mortality leading to global bird declines. Direct observations are relatively rarely documented compared with large numbers of birds hypothesized to be killed or wounded by cats. We analyzed data from two wildlife rehabilitation centers located in Salem and Grants Pass, Oregon USA, to understand which species were most likely to interact with a cat, and the species traits associated with cat interactions and habitats (urban vs. rural) of rescued birds. Interaction with a cat was the second-most commonly reported cause of admission, representing 12.3% of 6345 admissions. Half to two-thirds of birds were rescued from cats in urban settings and were usually species foraging on or near the ground. Most species were admitted to rehabilitation centers in direct proportion to their regional abundance. An exception was the absence of common species weighing less than 70 g, which we conclude is an effect of sampling bias. We conclude that cats most often interact with regionally common near-ground-dwelling bird species in both urban and rural habitats. Wildlife rehabilitation centers can provide valuable sources of data for cat-bird interactions but potential sources of uncertainty and bias in their data need to be considered carefully.
