The Centers for Medicare and Medicaid Services initiated three strategies (in March and July 2012 and in May 2013) to reduce the use of unnecessary antipsychotic medications in nursing homes, especially their widespread use to control behavioral symptoms of dementia. We examined 86,163 state recertification surveys conducted at 15,055 facilities in the period January 1, 2009-March 31, 2015. We found that these strategies were associated with increases in citations for only one of two targeted deficiencies (unnecessary drug use) and only after the third strategy (revisions to the federal guidelines for the citations) was implemented.

Frailty and sarcopenia are geriatrics syndromes that are increasing in the super aged society and are an important risk factor for the outcomes such as disability, falls, falls/fractures, and death. Although aging is a major factor in both syndromes, muscle weakness is accelerated by malnutrition such as protein and vitamin D deficiency and lack of exercise in a sedentary lifestyle. Therefore, nutritional guidance and exercise instruction are extremely important as well as management of diseases in older people.

Managerial Ownership in Nursing Homes: Staffing, Quality, and Financial Performance.

Gerontologist

November 2018

Department of Economics in the Farmer School of Business and Scripps Gerontology Center, Miami University, Oxford, Ohio.

Purpose Of The Study: Ownership of nursing homes (NHs) has primarily focused broadly on differences between for-profit (FP), nonprofit (NFP), and government-operated facilities. Yet, among FPs, the understanding of detailed ownership structures at individual NHs is rather limited. Particularly, NH administrators may hold significant equity interests in their facilities, leading to heterogeneous financial incentives and NH outcomes.

Quality of life (QoL) in the face of declining health, mobility, and social losses is a central issue for older adults. Our study examined changes in QoL over time for older adults residing in independent senior housing within continuing care retirement communities (CCRCs) and estimated how residents' social engagement during their first year influenced QoL over the next 4 years. Data were drawn from a 5-year panel study of 267 older adults who moved into senior housing within four CCRCs.

External and internal stimuli cause modifications to gene and biochemical pathways. In turn, demonstrating that biological systems continuously make short-term adaptations both to set-points, and to the range of "normal" capacity, due to mild conditional changes, or to subtoxic, nondamaging levels of chemical agents. This is termed as "Adaptive Homeostasis," defined with the following: "The transient expansion or contraction of the homeostatic range in response to exposure to sub-toxic, nondamaging, signaling molecules or events, or the removal or cessation of such molecules or events.

Who Hires Social Workers? Structural and Contextual Determinants of Social Service Staffing in Nursing Homes.

Health Soc Work

February 2017

Associate professor of economics, Farmer School of Business, and research fellow, Scripps Gerontology Center, Miami University, Oxford, OH, USA.

Although nurse staffing has been extensively studied within nursing homes (NHs), social services has received less attention. The study describes how social service departments are organized in NHs and examines the structural characteristics of NHs and other macro-focused contextual factors that explain differences in social service staffing patterns using longitudinal national data (Certification and Survey Provider Enhanced Reports, 2009-2012). NHs have three patterns of staffing for social services, using qualified social workers (QSWs); paraprofessional social service staff; and interprofessional teams, consisting of both QSWs and paraprofessionals.

Gerontological educators are increasingly interested in reducing college students' negative, and promoting their positive, attitudes toward older adults. Over the course of a semester, students from six 4-year institutions viewed three life story videos (documentaries) of older adults and completed pre- and posttest surveys that assessed their positive (Allophilia Scale) and negative (Fraboni Scale of Ageism) attitudes. The authors assessed changes in attitudinal scales between treatment (with videos, n = 80) and control (no video, n = 40) groups.

Formation and repair of oxidatively generated damage in cellular DNA.

Free Radic Biol Med

June 2017

Département de médecine nucléaire et radiobiologie, Faculté de médecine et des sciences de la santé, Université de Sherbrooke, Sherbrooke, Québec, Canada J1H 5N4.

In this review article, emphasis is placed on the critical survey of available data concerning modified nucleobase and 2-deoxyribose products that have been identified in cellular DNA following exposure to a wide variety of oxidizing species and agents including, hydroxyl radical, one-electron oxidants, singlet oxygen, hypochlorous acid and ten-eleven translocation enzymes. In addition, information is provided about the generation of secondary oxidation products of 8-oxo-7,8-dihydroguanine and nucleobase addition products with reactive aldehydes arising from the decomposition of lipid peroxides. It is worth noting that the different classes of oxidatively generated DNA damage that consist of single lesions, intra- and interstrand cross-links were unambiguously assigned and quantitatively detected on the basis of accurate measurements involving in most cases high performance liquid chromatography coupled to electrospray ionization tandem mass spectrometry.

4-Hydroxy-2-nonenal (HNE), one of the major α, β-unsaturated aldehydes produced during lipid peroxidation, is a potent messenger in mediating signaling pathways. Lipid peroxidation and HNE production appear to increase with aging. Although the cause and effect relation remains arguable, aging is associated with significant changes in diverse signaling events, characterized by enhanced or diminished responses of specific signaling pathways.

Signaling by 4-hydroxy-2-nonenal: Exposure protocols, target selectivity and degradation.

Arch Biochem Biophys

March 2017

Andrus Gerontology Center of the Leonard Davis School of Gerontology, University of Southern California, 3715 McClintock Ave, Los Angeles, CA 90089-0191, USA.

4-hydroxy-2-nonenal (HNE), a major non-saturated aldehyde product of lipid peroxidation, has been extensively studied as a signaling messenger. In these studies a wide range of HNE concentrations have been used, ranging from the unstressed plasma concentration to far beyond what would be found in actual pathophysiological condition. In addition, accumulating evidence suggest that signaling protein modification by HNE is specific with only those proteins with cysteine, histidine, and lysine residues located in certain sequence or environments adducted by HNE.
