Family Caregiving to the Older Population: Background, Federal Programs, and Issues for Congress

[Excerpt] Family caregiving to older individuals in need of long-term care encompasses a wide range of activities, services, and supports. Caregiving can include assistance with personal care needs, such as bathing, dressing, and eating, as well as other activities necessary for independent living, such as shopping, medication management, and meal preparation. In addition, family caregivers may arrange, supervise, or pay for formal or paid care to be provided to the care recipient. Family caregivers fulfill the majority of the need for long-term care by older persons with chronic disabilities in the United States. As a result of increases in life expectancy, as well as the aging of the baby-boom generation, demand for family caregiving to the older population is likely to increase. However, demographic trends such as reduced fertility, increased divorce rates, and greater labor force participation among women may limit the number of available caregivers to older individuals, as well as the capacity for caregivers to provide needed care. Although many family caregivers find caregiving for an older family member a rewarding experience, other life circumstances, in addition to caregiving, may increase caregiver stress. For example, family members may not live in close proximity to the care recipient, they may face the competing demands of child care and elder care, and they may have to manage work with caregiving responsibilities. As a result, family caregiving can lead to emotional and physical strain and financial hardship. These effects are more likely to be felt among those caring for persons with high levels of disability or cognitive impairment. Caregiver stress has been linked to nursing home admission for the care recipient, thus interventions that can reduce stress may also reduce nursing home placement. Recognizing family caregivers as an important part of the nation\u27s long-term care delivery system, the federal government has established programs and initiatives that provide direct supports to caregivers, such as respite care, education and training, tax relief, and cash assistance. These benefits are targeted at family caregivers to reduce stress and financial hardship, and to improve caregiving skills, among other things. Other federal programs and initiatives provide home- and community-based long-term care services and supports to the care recipient. These programs can indirectly benefit caregivers in relieving caregiver burden by either supplementing the informal care they are providing or substituting with paid support. Three sets of policies that would provide direct assistance to family caregivers to older adults are briefly discussed in the last section of this report. These policy issues, which have been the subject of discussion among federal policymakers and other interested stakeholders, include the following: caregiver services and supports, flexible workplace accommodations and income security, and additional tax credits. This report will be updated as warranted

Quando se inicia o processo de alfabetização?

Embora a aprendizagem informal da língua escrita na fase pré-escolarjá fosse observada desde o século XIX, muitos anos se passaram até que fosse reconhecida. Com as pesquisas lideradas por Vygotsky, Luria, Ferreiro e os estudos sobre letramento, foi possível recuperar a gênese da alfabetização e considerar suas implicações para o ensino. Assim, importa perguntar: Como compreender as primeiras escritas? Como o reconhecimento delas pode afetar as concepções sobre a língua escrita? Que condições favorecem a construção da escrita? Que implicações as aprendizagens pré-escolares trazem para as práticas pedagógicas e para as políticas de alfabetização? Com o objetivo de aprofundar o entendimento destas questões, o artigo vale - se de um estudo de caso sobre a produção textual de um menino de quatro anos, configurando-se como mais um a iniciativa para subsidiar os debates sobre a articulação entre ensino e aprendizagem.Although the informal acquisition of writi ng skills in preschool had already been observed since the nineteenth century, many years passed before it was officially recognized. By researches conducted by Vygotsky, Luria, Ferreiro and other studies on literacy, it was possible to retrieve when the i nception of the language learning process took place and to take into account its implications for education. Therefore, it is important to ask: How do we understand the early writings? How can recognizing them affect the teacher’s concept of written langu age? What conditions favour the writing production? What implications does the preschool learning process bring to pedagogical practices and literacy policies? With the goal of further deepening the understanding of those matters, the article makes use of a case study on the textual production of a four - year - old boy, which represents one more initiative for supporting the debates on the articulation between education and learning process.

Elucidating the Role of Injury-Induced Electric Fields (EFs) in Regulating the Astrocytic Response to Injury in the Mammalian Central Nervous System

Injury to the vertebrate central nervous system (CNS) induces astrocytes to change their morphology, to increase their rate of proliferation, and to display directional migration to the injury site, all to facilitate repair. These astrocytic responses to injury occur in a clear temporal sequence and, by their intensity and duration, can have both beneficial and detrimental effects on the repair of damaged CNS tissue. Studies on highly regenerative tissues in non-mammalian vertebrates have demonstrated that the intensity of direct-current extracellular electric fields (EFs) at the injury site, which are 50–100 fold greater than in uninjured tissue, represent a potent signal to drive tissue repair. In contrast, a 10-fold EF increase has been measured in many injured mammalian tissues where limited regeneration occurs. As the astrocytic response to CNS injury is crucial to the reparative outcome, we exposed purified rat cortical astrocytes to EF intensities associated with intact and injured mammalian tissues, as well as to those EF intensities measured in regenerating non-mammalian vertebrate tissues, to determine whether EFs may contribute to the astrocytic injury response. Astrocytes exposed to EF intensities associated with uninjured tissue showed little change in their cellular behavior. However, astrocytes exposed to EF intensities associated with injured tissue showed a dramatic increase in migration and proliferation. At EF intensities associated with regenerating non-mammalian vertebrate tissues, these cellular responses were even more robust and included morphological changes consistent with a regenerative phenotype. These findings suggest that endogenous EFs may be a crucial signal for regulating the astrocytic response to injury and that their manipulation may be a novel target for facilitating CNS repair

Identification and detection of iha subtypes in LEE-negative Shiga toxin-producing Escherichia coli (STEC) strains isolated from humans, cattle and food

LEE-negative Shiga toxin-producing Escherichia coli (STEC) strains are important cause of infection in humans and they should be included in the public health surveillance systems. Some isolates have been associated with haemolytic uremic syndrome (HUS) but the mechanisms of pathogenicity are is a field continuos broadening of knowledge. The IrgA homologue adhesin (Iha), encoded by iha, is an adherence-conferring protein and also a siderophore receptor distributed among LEE-negative STEC strains. This study reports the presence of different subtypes of iha in LEE-negative STEC strains. We used genomic analyses to design PCR assays for detecting each of the different iha subtypes and also, all the subtypes simultaneously. LEE-negative STEC strains were designed and different localizations of this gene in STEC subgroups were examinated.Genomic analysis detected iha in a high percentage of LEE-negative STEC strains. These strains generally carried iha sequences similar to those harbored by the Locus of Adhesion and Autoaggregation (LAA) or by the plasmid pO113. Besides, almost half of the strains carried both subtypes. Similar results were observed by PCR, detecting iha LAA in 87% of the strains (117/135) and iha pO113 in 32% of strains (43/135). Thus, we designed PCR assays that allow rapid detection of iha subtypes harbored by LEE-negative strains. These results highlight the need to investigate the individual and orchestrated role of virulence genes that determine the STEC capacity of causing serious disease, which would allow for identification of target candidates to develop therapies against HUS.Fil: Colello, Rocío.

Antibiotic resistance and integrons in Shiga toxin-producing Escherichia coli (STEC)

Shiga toxin-producing Escherichia coli (STEC) cause hemorrhagic colitis (HC) and hemolyticuremic syndrome in humans (HUS). Cattle are the main reservoir of STEC and transmission to humans occurs through contaminated food and water. Antibiotics are used in pig production systems to combat disease and improve productivity and play a key role in the dissemination of antibiotic resistance genes to the bacteria. Integrons have been identified in resistant bacteria allowing for the acquisition and dissemination of antibiotic resistance genes. STEC strains isolated from humans and animals have developed antibiotic resistance. In our laboratory, 21 non-157 STEC strains isolated from pigs were analyzed to detect class 1 and 2 integrons by PCR. Eight carried integrons, 7 of them harbored intl2. In another study 545 STEC strains were also analyzed for the presence of intl1 and intl2. Strains carrying intl1 belonged to isolates from environment (n = 1), chicken hamburger (n = 2), dairy calves (n = 4) and pigs (n = 8). Two strains isolated from pigs harbored intl2 and only one intl1/intl2, highlighting the presence of intl2 in pigs. The selection for multiresistant strains may contribute to the emergence of antibiotic resistant pathogens and facilitate the spreading of the mobile resistance elements to other bacteria

Catalog of selected heavy duty transport energy management models

A catalog of energy management models for heavy duty transport systems powered by diesel engines is presented. The catalog results from a literature survey, supplemented by telephone interviews and mailed questionnaires to discover the major computer models currently used in the transportation industry in the following categories: heavy duty transport systems, which consist of highway (vehicle simulation), marine (ship simulation), rail (locomotive simulation), and pipeline (pumping station simulation); and heavy duty diesel engines, which involve models that match the intake/exhaust system to the engine, fuel efficiency, emissions, combustion chamber shape, fuel injection system, heat transfer, intake/exhaust system, operating performance, and waste heat utilization devices, i.e., turbocharger, bottoming cycle
