  1. Tamm-Langmuir surface waves

    In this work we develop a theory of surface electromagnetic waves localized at the interface of periodic metal-dielectric structures. We have shown that the anisotropy of plasma frequency in metal layers lifts the degeneracy of plasma oscillations and opens a series of photonic band gaps. This results in appearance of surface waves with singular density of states—we refer to them as Tamm-Langmuir waves. Such naming is natural since we have found that their properties are very similar to the properties of both bulk Langmuir and surface Tamm waves. Depending on the anisotropy parameters, Tamm-Langmuir waves can be either forward or backward waves. Singular density of states and high sensitivity of the dispersion to the anisotropy of the structure makes Tamm-Langmuir waves very promising for potential applications in nanophotonics and biosensing.

    1990-01-01

    CASA Uno data from sites distributed in longitude from Australia to Europe have been used to determine orbits of the GPS satellites. The characteristics of the orbits determined from double difference phase have been evaluated through comparisons of two-week solutions with one-week solutions and by comparisons of predicted and estimated orbits. Evidence of unmodeled effects is demonstrated, particularly associated with the orbit planes that experience solar eclipse. The orbit accuracy has been assessed through the repeatability of unconstrained estimated baseline vectors ranging from 245 km to 5400 km. Both the baseline repeatability and the comparison with independent space geodetic methods give results at the level of 1-2 parts in 100,000,000. In addition, the Mojave/Owens Valley (245 km) and Kokee Park/Ft. Davis (5409 km) estimates agree with VLBI and SLR to better than 1 part in 100,000,000.

    The purpose of this article is to describe the work conducted in the aerodynamic field throughout the 4-year development and engineering time span required by the project of the UNO car. A description is given of all the parametric studies carried out. Through these studies two types of cars at present in production were defined and the characteristics of a possible future sports version laid down. A movable device, to be fitted in the back window, was also set up and patented. When actuated it reduces soiling of back window. A description is also provided of the measurements made in the car flow field and some considerations are outlined about the method applied. This method is still in development phase but it already permits some considerations and in-depth investigations to be made on the vehicle wake.

  4. Tamm State-Coupled Emission: Effect of Probe Location and Emission Wavelength

    PubMed Central

    2015-01-01

    We report the effect of the probe location and wavelength on the emission spatial distribution and spectral properties of fluorophores located on structures which display Tamm states. Our structure consists of a one-dimensional photonic crystal (1DPC)—that is, a multilayer structure of alternate high and low refractive index dielectrics—and a thin top silver film. Simulations show the presence of Tamm and surface plasmon modes in the structure. The electric field intensities for the Tamm modes are located mostly in the dielectric layer below the metal film. The corresponding field intensities for the surface plamon modes are located above the metal film in the distal side. Tamm states can be in resonance with the incident light normal or near normal to the surface, within the light line, and can be accessed without the use of a coupling prism or gratings. We investigated the emission spectra and angular distribution of the emission for probes located above and below the metal film to explore the interaction of fluorophores with Tamm plasmons and surface plasmons modes. Three probes were chosen with different overlap of the emission spectra with the Tamm modes. The fluorophores below the metal film coupled predominantly with the Tamm state and displayed more intense and only Tamm state-coupled emission (TSCE). Probes above the metal film display both surface plasmon-coupled emission (SPCE) and Tamm state-coupled emission. In contrast to SPCE, which shows only KR, P-polarized emission, the Tamm states can display both S- and P-polarized emission and can be populated using both RK and KR illuminations. The TSCE angle is highly sensitive to wavelength, which suggests the use of Tamm structures to provide both directional emission and wavelength dispersion. The combination of plasmonic and photonic structures with directional emission close to surface normal offers the opportunities for new design formats for clinical testing, portable devices, and other

  5. Confinement of gigahertz sound and light in Tamm plasmon resonators

    We demonstrate theoretically and by pump-probe picosecond acoustics experiments the simultaneous confinement of light and gigahertz sound in Tamm plasmon resonators, formed by depositing a thin layer of Au onto a GaAs/AlGaAs Bragg reflector. The cavity has InGaAs quantum dots (QDs) embedded at the maximum of the confined optical field in the first GaAs layer. The different sound generation and detection mechanisms are theoretically analyzed. It is shown that the Au layer absorption and the resonant excitation of the QDs are the more efficient light-sound transducers for the coupling of near-infrared light with the confined acoustic modes, while the displacement of the interfaces is the main back-action mechanism at these energies. The prospects for the compact realization of optomechanical resonators based on Tamm plasmon cavities are discussed.

    1. Binding between the radiolabelled loop-acting diuretics ([14C]frusemide, [14C]ethacrynic acid and [3H]bumetanide) and human Tamm-Horsfall glycoprotein or human serum albumin in vitro was evaluated by equilibrium dialysis. 2. The diuretic action and binding to urinary Tamm-Horsfall glycoprotein of the radiolabelled diuretics in vivo, after intravenous administration, were examined in rabbits. 3. In vitro, all three radiolabelled diuretics bound strongly to human serum albumin, but not to Tamm-Horsfall glycoprotein. 4. Radiolabelled frusemide and bumetanide, but not ethacrynic acid, caused a diuresis in rabbits, but no binding between the drugs and Tamm-Horsfall glycoprotein was seen in vivo. 5. Binding to Tamm-Horsfall glycoprotein does not appear to be an important mechanism in the action of loop diuretics.

    We present evidence for the existence of a hybrid state of Tamm plasmons and microcavity exciton polaritons in a II-VI material based microcavity sample covered with an Ag metal layer. The bare cavity mode shows a characteristic anticrossing with the Tamm-plasmon mode, when microreflectivity measurements are performed for different detunings between the Tamm plasmon and the cavity mode. When the Tamm-plasmon mode is in resonance with the cavity polariton four hybrid eigenstates are observed due to the coupling of the cavity-photon mode, the Tamm-plasmon mode, and the heavy- and light-hole excitons. If the bare Tamm-plasmon mode is tuned, these resonances will exhibit three anticrossings. Experimental results are in good agreement with calculations based on the transfer matrix method as well as on the coupled-oscillators model. The lowest hybrid eigenstate is observed to be red shifted by about 13 meV with respect to the lower cavity polariton state when the Tamm plasmon is resonantly coupled with the cavity polariton. This spectral shift which is caused by the metal layer can be used to create a trapping potential channel for the polaritons. Such channels can guide the polariton propagation similar to one-dimensional polariton wires. PMID:27698359

    We report on electro optical tuning of the emission from GaAs quantum wells resonantly coupled to a Tamm-plasmon mode in a hybrid metal/dielectric structure. The structures were studied via momentum resolved photoluminescence and photoreflectance spectroscopy, and the surface metal layer was used as a top gate, which allowed for a precise tuning of the quantum well emission via the quantum confined Stark effect. By tuning the resonance, we were able to observe the characteristic anticrossing behavior of a polaritonic emission in the strong light-matter coupling regime, yielding a Rabi splitting of (9.2 ± 0.2) meV.

    In this study, we investigate localized and resonant optical waves associated with a semi-infinite superlattice made out of superconductor-dielectric bilayers and terminated with a cap layer. Both transverse electric and transverse magnetic waves are considered. These surface modes are analogous to the so-called Tamm states associated with electronic states found at the surface of materials. The surface guided modes induced by the cap layer strongly depend on whether the superlattice ends with a superconductor or a dielectric layer, the thickness of the surface layer, the temperature of the superconductor layer as well as on the polarization of the waves. Different kinds of surface modes are found and their properties examined. These structures can be used to realize the highly sensitive photonic crystal sensors.

    2016-09-01

    Tamm states localized at the interface between a homogeneous potential barrier and a combined magneto-electric potential barriers superlattice in monolayer graphene have been theoretically investigated. The results show that the symmetries of Tamm states are different when the components of the superlattice are different. When the single unit of the superlattice consists of double anti-parallel potential barriers and two gaps, Tamm states present symmetry about momentum wave vector ky‧ = 0 at the same intensity of the homogeneous potential barrier (Vs). When the single unit of the superlattice consists of double anti-parallel magnetic potential barriers and two gaps, it demonstrates that Tamm states at positive Vs are symmetric to that at negative Vs about the electron incident energy E0 = 0. When the single unit of the superlattice consists of double anti-parallel combined magneto-electric potential barriers, the band gap at Dirac point is opened, Tamm states exhibit no symmetry about ky‧ or the electron incident energy whether at the same Vs or at positive and negative Vs.

    Unconventional optical Tamm surface states have been demonstrated in transmission and reflectance spectra of three-dimensional opal photonic crystals coated by thin metal films. These states appear in registry with diffraction resonances and localize the electromagnetic energy in asymmetric resonators formed by stacks of lattice planes and metal semishells. Tamm defect states provide the bypass for light at the edges of the Bragg diffraction resonances and thus reduce the diffraction efficiency. Despite the hidden nature of this effect, its magnitude is comparable to the extraordinary transmission associated with the surface-plasmon polaritons that are simultaneously excited at the surfaces of the corrugated metal films.

    Optical Tamm surface states are formed in 3-dimensional photonic crystals coated by thin metal films. These states appear in registry with diffraction resonances and localize the electromagnetic energy in resonators formed by diffraction mirrors of lattice planes and metal semishells. Tamm defect states provide the bypass for light in the spectral range of photonic stop-bands and thus reduce the efficiency of the Bragg diffraction resonances. In spite of hidden nature of this effect, its magnitude is comparable to the extraordinary transmission associated with tunneling of surface plasmon polaritons, which are simultaneously excited at surfaces of corrugated metal film coating.

    We present evidence of optical Tamm states to surface plasmon polariton (SPP) coupling. We experimentally demonstrate that for a Bragg stack with a thin metal layer on the surface, hybrid Tamm-SPP modes may be excited when a grating on the air-metal interface is introduced. Out-coupling via the grating to free space propagation is shown to enhance the transmission as well as the directionality and polarization selection for the transmitted beam. We suggest that this system will be useful on those devices, where a metallic electrical contact as well as beaming and polarization control is needed.

  16. Dyakonov-Tamm waves guided by the interface between two structurally chiral materials that differ only in handedness

    The boundary-value problem of the propagation of Dyakonov-Tamm waves guided by the planar interface between two structurally chiral materials that are identical except for structural handedness was formulated and numerically solved. Detailed analysis showed that either two or three different Dyakonov-Tamm waves can propagate. These waves have different phase speeds and degrees of localization to the interface with a sudden handedness change. The most localized Dyakonov-Tamm waves are essentially confined to within a small number of structural periods of the interface on either side.

    There is a continuing need to increase the brightness and photostability of fluorophores for use in biotechnology, medical diagnostics and cell imaging. One approach developed during the past decade is to use metallic surfaces and nanostructures. It is now known that excited state fluorophores display interactions with surface plasmons, which can increase the radiative decay rates, modify the spatial distribution of emission and result in directional emission. One important example is Surface Plasmon-Coupled Emission (SPCE). In this phenomenon the fluorophores at close distances from a thin metal film, typically silver, display emission over a small range of angles into the substrate. A disadvantage of SPCE is that the emission occur at large angles relative to the surface normal, and at angles which are larger than the critical angle for the glass substrate. The large angles make it difficult to collect all the coupled emission and have prevented use of SPCE with high-throughput and/or array applications. In the present report we describe a simple multi-layer metal-dielectric structure which allows excitation with light that is perpendicular (normal) to the plane and provides emission within a narrow angular distribution that is normal to the plane. This structure consist of a thin silver film on top of a multi-layer dielectric Bragg grating, with no nanoscale features except for the metal or dielectric layer thicknesses. Our structure is designed to support optical Tamm states, which are trapped electromagnetic modes between the metal film and the underlying Bragg grating. We used simulations with the transfer matrix method to understand the optical properties of Tamm states and localization of the modes or electric fields in the structure. Tamm states can exist with zero in-plane wavevector components and can be created without the use of a coupling prism. We show that fluorophores on top of the metal film can interact with the Tamm state under the metal film

    2016-11-01

    The propagation of Dyakonov-Tamm waves guided by the planar interface of an isotropic topological insulator and a structurally chiral material, both assumed to be nonmagnetic, was investigated by numerically solving the associated canonical boundary-value problem. The topologically insulating surface states of the topological insulator were quantitated via a surface admittance {γ }{{TI}}, which significantly affects the phase speeds and the spatial profiles of the Dyakonov-Tamm waves. Most significantly, it is possible that a Dyakonov-Tamm wave propagates co-parallel to a vector {u} in the interface plane, but no Dyakonov-Tamm wave propagates anti-parallel to {u}. The left/right asymmetry, which vanishes for {γ }{{TI}}=0, is highly attractive for one-way on-chip optical communication.

    In January 1988, scientists from over 25 organizations in 13 countries and territories cooperated in the largest GPS campaign in the world to date. A total of 43 GPS receivers collected approximately 590 station-days of data in American Samoa, Australia, Canada, Colombia, Costa Rica, Ecuador, New Zealand, Norway, Panama, Sweden, United States, West Germany, and Venezuela. The experiment was entitled CASA Uno. Scientific goals of the project include measurements of strain in the northern Andes, subduction rates for the Cocos and Nazca plates beneath Central and South America, and relative motion between the Caribbean plate and South America. A second set of measurements are planned in 1991 and should provide preliminary estimates of crustal deformation and plate motion rates in the region.

    The technique of rapid evaporation of whole urine to standard osmolality has been studied further and quantitative measurements made of the calcium oxalate crystals resulting, firstly by a microscope method and secondly by isotope method using 14C-oxalate. It is confirmed that ultrafiltration of urine prior to evaporation leads to a large reduction in calcium oxalate crystal formation and that this is largely restored by addition of human urinary Tamm-Horsfall protein (uromucoid). Albumin does not have this effect.

    NH is the most common identifiable cause of ALF in the neonate. LT is the definitive treatment for neonates with NH who have failed medical therapy. Our aim was to determine the outcomes of LT in infants with NH. Patients (less than one yr of age) with NH who were listed for LT and patients who underwent LT between 1994 and 2013 were identified from the UNOS database for analysis. Risk factors for death and graft loss were analyzed by multivariate logistic regression. Thirty-eight infants with NH with a total of 43 transplants were identified. One- and five-yr patient and graft survival were 84.2%, 81.6%, 71.1%, and 68.4%, respectively. The outcomes for NH were not significantly different when compared to the same age-matched recipients with other causes of ALF. There were no statistically significant risk factors identified for graft loss or death. Ninety infants with NH were listed for LT. Reasons for removal included transplanted (49%), death (27%), too sick to transplant (7%), and improved status (13%). LT for infants with NH has a high rate of graft loss and death; however, outcomes are comparable to the same age-matched recipients with other causes of ALF.

    In this paper, we characterize the electric field distribution of confined optical modes in a 0D Tamm structure, consisting in a metallic disk deposited on a Bragg mirror. The modes are probed at room temperature, through the fluorescence of semiconductor colloidal nanocrystals. We perform a combined analysis of the resonant modes distribution in both direct space and Fourier space and show, in good agreement with numerical simulations, that a subportion of the structure will radiate with a different angular distribution depending on its position. Such analysis is shown to probe the gradient of the phase of the confined optical modes.

These cavities support a zoo of various resonances, including hyperbolic Tamm plasmons and hyperbolic Fabry-Perot modes, which feature anisotropic clover-leaf dispersion parallel to the metasurface and strong coupling between TM and TE polarizations in the modes. The properties and spectrum of the modes are highly tunable by the dimensional and material parameters of the structure and can be used for directional emission, modification of radiation produced by electric dipole emitters into magnetic dipole radiation as well as 90 degree polarization rotators and polarization rotation mirrors.

    Working within the Tamm-Dancoff approximation, we calculate the derivative couplings between time-dependent density-functional theory excited states by assuming that the Kohn-Sham superposition of singly excited determinants represents a true electronic wavefunction. All Pulay terms are included in our derivative coupling expression. The reasonability of our approach can be established by noting that, for closely separated electronic states in the infinite basis limit, our final expression agrees exactly with the Chernyak-Mukamel expression (with transition densities from response theory). Finally, we also validate our approach empirically by analyzing the behavior of the derivative couplings around the {T}1/{T}2 conical intersection of benzaldehyde.

Specifically, we study its various representations and find the condition satisfied by the deformed q-number to define the algebra structure function. Particular Fock spaces involving finite and infinite dimensions are examined. A deformed calculus is performed as well as a coordinate realization for this algebra. A relevant example is exhibited. Associated coherent states are constructed. Finally, some thermodynamics aspects are computed and discussed.

    Tamm plasmons (TPs) are the result of trapping optical energy at the interface between a metal film and a one-dimensional photonic crystal. In contrast to surface plasmons, TPs display unique properties such as the ability of direct optical excitation without the aid of prisms, or gratings, being populated using both S- and P- polarized light, and importantly, they can be created with incident light normal to the surfaces. This latter property has recently been used to obtain Tamm plasmon-coupled emission (TPCE) which beams along a path directly perpendicular to the surface. In this paper the effects of metal film thickness on TPCE are investigated using back focal plane (BFP) imaging and spectral resolutions. The observed experimental results are in agreement with the numerical simulations. The present work provides the basic understanding to design the structures for TPCE, which in turn has potential applications in the fabrication of the active material for light emitting devices, fluorescence based-sensing using microarrays and imaging.

    Rabbit antibodies to human Tamm-Horsfall glycoprotein (prepared by salt precipitation from normal urine) were purified by affinity chromatography using columns containing Tamm-Horsfall glycoprotein linked to CNBr-activated Sepharose 4B. The specificity of these antibodies was determined by analysis of their binding characteristics on Western blots of Tamm-Horsfall protein from sodium dodecyl sulphate/polyacrylamide gradient gels and comparison with the reactivity of monoclonal antibodies to this glycoprotein. Optimal conditions of adsorption to poly(vinyl chloride) microtitre plates were established such that these purified antibodies could be used in a solid-phase radioimmunoassay for the determination of urinary Tamm-Horsfall-glycoprotein concentration. The specificity of the immunoassay was confirmed by competitive inhibition of the urinary Tamm-Horsfall glycoprotein by purified freeze-dried material in solution. A standard curve obtained with this material showed the radioimmunoassay to have a sensitivity of at least 5 ng/ml, with linearity between 30 and 600 ng/ml. The mean coefficient of variation over the linear section of the curve was 11.3 +/- 2.2% (n = 13). The effects of dialysis and freezing of urine samples before determination of Tamm-Horsfall-glycoprotein concentrations were investigated and the mean 24 h urinary excretion rate in 60 normal donors was shown to be 84.9 +/- 44.1 mg.

    The particle-particle random phase approximation (pp-RPA) and the particle-particle Tamm-Dancoff approximation (pp-TDA) are applied to the challenging conical intersection problem. Because they describe the ground and excited states on the same footing and naturally take into account the interstate interaction, these particle-particle methods, especially the pp-TDA, can correctly predict the dimensionality of the conical intersection seam as well as describe the potential energy surface in the vicinity of conical intersections. Though the bond length of conical intersections is slightly underestimated compared with the complete-active-space self-consistent field (CASSCF) theory, the efficient particle-particle methods are promising for conical intersections and nonadiabatic dynamics.

    We report the implementation of a two-component variant of time-dependent density functional theory (TDDFT) for hybrid functionals that accounts for spin-orbit effects within the Tamm-Dancoff approximation (TDA) for closed-shell systems. The influence of the admixture of Hartree-Fock exchange on excitation energies is investigated for several atoms and diatomic molecules by comparison to numbers for pure density functionals obtained previously [M. Kühn and F. Weigend, J. Chem. Theory Comput. 9, 5341 (2013)]. It is further related to changes upon switching to the local density approximation or using the full TDDFT formalism instead of TDA. Efficiency is demonstrated for a comparably large system, Ir(ppy)3 (61 atoms, 1501 basis functions, lowest 10 excited states), which is a prototype molecule for organic light-emitting diodes, due to its "spin-forbidden" triplet-singlet transition.

    We report the implementation of a two-component variant of time-dependent density functional theory (TDDFT) for hybrid functionals that accounts for spin-orbit effects within the Tamm-Dancoff approximation (TDA) for closed-shell systems. The influence of the admixture of Hartree-Fock exchange on excitation energies is investigated for several atoms and diatomic molecules by comparison to numbers for pure density functionals obtained previously [M. Kühn and F. Weigend, J. Chem. Theory Comput. 9, 5341 (2013)]. It is further related to changes upon switching to the local density approximation or using the full TDDFT formalism instead of TDA. Efficiency is demonstrated for a comparably large system, Ir(ppy){sub 3} (61 atoms, 1501 basis functions, lowest 10 excited states), which is a prototype molecule for organic light-emitting diodes, due to its “spin-forbidden” triplet-singlet transition.

    The particle-particle random phase approximation (pp-RPA) and the particle-particle Tamm-Dancoff approximation (pp-TDA) are applied to the challenging conical intersection problem. Because they describe the ground and excited states on the same footing and naturally take into account the interstate interaction, these particle-particle methods, especially the pp-TDA, can correctly predict the dimensionality of the conical intersection seam as well as describe the potential energy surface in the vicinity of conical intersections. Though the bond length of conical intersections is slightly underestimated compared with the complete-active-space self-consistent field (CASSCF) theory, the efficient particle-particle methods are promising for conical intersections and nonadiabatic dynamics.

    Working within the Tamm-Dancoff approximation, we calculate the derivative couplings between time-dependent density-functional theory excited states by assuming that the Kohn-Sham superposition of singly excited determinants represents a true electronic wavefunction. All Pulay terms are included in our derivative coupling expression. The reasonability of our approach can be established by noting that, for closely separated electronic states in the infinite basis limit, our final expression agrees exactly with the Chernyak-Mukamel expression (with transition densities from response theory). Finally, we also validate our approach empirically by analyzing the behavior of the derivative couplings around the T{sub 1}/T{sub 2} conical intersection of benzaldehyde.

    Three different schemes are employed to solve the benchmark problem. The first one is a conventional TVD-MUSCL (Monotone Upwind Schemes for Conservation Laws) scheme. The second scheme is a UNO3-ACM (Uniformly Non-Oscillatory Artificial Compression Method) scheme. The third scheme is an optimized compact finite difference scheme modified by us: the 4th order Runge Kutta time stepping, the 4th order pentadiagonal compact spatial discretization with the maximum resolution characteristics. The problems of category 1 are solved by using the second (UNO3-ACM) and third (Optimized Compact) schemes. The problems of category 2 are solved by using the first (TVD3) and second (UNO3-ACM) schemes. The problem of category 5 is solved by using the first (TVD3) scheme. It can be concluded from the present calculations that the Optimized Compact scheme and the UN03-ACM show good resolutions for category 1 and category 2 respectively.

  16. The optical Tamm states at the interface between a photonic crystal and a nanocomposite containing core-shell particles

    We investigate the optical Tamm states (OTSs) localized at the interface between a photonic crystal (PC) and a nanocomposite consisting of spherical nanoparticles with a dielectric core and a metallic shell, which are dispersed in a transparent matrix, and is characterized by the resonance permittivity. Spectra of transmission, reflection, and absorption of normally incident light waves by the investigated structure are calculated. The spectral manifestation of the Tamm states caused by negative values of the real part of the effective permittivity in the visible spectral range is studied. It is demonstrated that, along with the significantly extended band gap of the PC, the transmission spectrum contains an additional stopband caused by nanocomposite absorption near the resonance frequency. It is shown that the OTSs can be implemented in two band gaps of the PCs, each corresponding to a certain plasmon resonance frequency of the nanocomposite. It is established that the characteristics of the Tamm state localized at the edge of the PCs significantly depend on the ratio between the particle core volume and the total particle volume.

    Over the last two decades advances in semiconductor detector technology have reached the point where they are sufficiently sensitive to become an alternative to scintillators for high energy gamma ray detection for application in fields such as medical imaging. This paper assessed the Cadmium-Telluride (CdTe) XRI-UNO semiconductor detector produced by X-RAY Imatek for photon energies of interest in nuclear imaging. The XRI-UNO detector was found to have an intrinsic spatial resolution of <0.5mm and a high incident count rate capability up to at least 1680cps. The system spatial resolution, uniformity and sensitivity characteristics are also reported.

    This study describes the in vitro activation of human mononuclear phagocytes by particulate Tamm Horsfall protein (THP). Peripheral blood monocytes phagocytosed THP particles with the accompanying release of superoxide radicals, N-acetyl-beta-D-glucosaminidase, and neutral metalloproteinase. Immunoprecipitation and substrate gel analysis identified the neutral proteinase as a 95-kd gelatinase. A comparison with other particulate ligands highlighted the specificity of the response to THP and showed that the magnitude of the response was comparable with that obtained with lipopolysaccharide (100 micrograms/ml). Parallel studies using peritoneal macrophages resulted in a similar pattern of enzyme release and reactive oxygen species synthesis. THP has been implicated in the pathogenesis of tubulointerstitial nephritis associated with reflux nephropathy. The present study indicates that an inflammatory response initiated by a neutrophil-THP interaction may be extended into a chronic phase via the activation of mononuclear phagocytes. The subsequent release of reactive oxygen metabolites and proteinases may contribute to the tissue damage and fibrosis associated with chronic immune-mediated tubulointerstitial nephritis.

    Tamm-Horsfall glycoprotein (TH) distribution was studied using a biotin-avidin immunoperoxidase technique in renal biopsies from 166 consecutive patients and 8 normal kidneys. Tubulointerstitial damage was independently assessed and graded. In 109 patients TH antibodies were measured by ELISA and in 30 of these urinary TH and beta 2-microglobulin excretions were measured by radioimmunoassay. In 124 biopsies only distal tubular epithelium and casts were stained. Glomerular space (8) or interstitial (34) deposits were seen in 42 biopsies; 16/68 with glomerulonephritis, 4/14 with systemic vasculitis, 12/33 with chronic interstitial nephritis, 1/8 with acute interstitial nephritis, 9/43 with other nephropathies. There was no correlation between TH distribution and the degree of tubulointerstitial damage (p greater than 0.5), urinary TH excretion (p greater than 0.05), urinary beta 2-microglobulin excretion (p greater than 0.05), glomerular filtration rate, urinary concentrating ability, or the incidence of pyuria. TH antibodies did not correlate with TH distribution (p greater than 0.5) or the degree of tubulointerstitial damage. Abnormal TH distribution showed no statistical relationship to the degree of tubulointerstitial damage, changes in renal function or levels of TH antibodies.

    Linear optical properties can be accurately calculated using the Bethe-Salpeter equation. After introducing a suitable product basis for the electron-hole pairs, the Bethe-Salpeter equation is usually recast into a complex non-Hermitian eigenvalue problem that is difficult to solve using standard eigenvalue solvers. In solid-state physics, it is therefore common practice to neglect the problematic coupling between the positive- and negative-frequency branches, reducing the problem to a Hermitian eigenvalue problem [Tamm-Dancoff approximation (TDA)]. We use time-inversion symmetry to recast the full problem into a quadratic Hermitian eigenvalue problem, which can be solved routinely using standard eigenvalue solvers even at a finite wave vector q . This allows us to access the importance of the coupling between the positive- and negative-frequency branch for prototypical solids. As a starting point for the Bethe-Salpeter calculations, we use self-consistent Green's-function methods (GW ), making the present scheme entirely ab initio. We calculate the optical spectra of carbon (C), silicon (Si), lithium fluoride (LiF), and the cyclic dimer Li2F2 and discuss why the differences between the TDA and the full solution are tiny. However, at finite momentum transfer q , significant differences between the TDA and our exact treatment are found. The origin of these differences is explained.

    In this article, we develop systematically second random phase approximations (RPA) and Tamm-Dancoff approximations (TDA) of particle-hole and particle-particle channels for calculating molecular excitation energies. The second particle-hole RPA/TDA can capture double excitations missed by the particle-hole RPA/TDA and time-dependent density-functional theory (TDDFT), while the second particle-particle RPA/TDA recovers non-highest-occupied-molecular-orbital excitations missed by the particle-particle RPA/TDA. With proper orbital restrictions, these restricted second RPAs and TDAs have a formal scaling of only O(N4). The restricted versions of second RPAs and TDAs are tested with various small molecules to show some positive results. Data suggest that the restricted second particle-hole TDA (r2ph-TDA) has the best overall performance with a correlation coefficient similar to TDDFT, but with a larger negative bias. The negative bias of the r2ph-TDA may be induced by the unaccounted ground state correlation energy to be investigated further. Overall, the r2ph-TDA is recommended to study systems with both single and some low-lying double excitations with a moderate accuracy. Some expressions on excited state property evaluations, such as < hat{S}2rangle are also developed and tested.

    Carotenoids are known to play a fundamental role in photosynthetic light-harvesting (LH) complexes; however, an accurate quantum-mechanical description of that is still missing. This is due to the multideterminant nature of the involved electronic states combined with an extended conjugation which limits the applicability of many of the most advanced approaches. In this study, we apply a multireference configuration interaction extension of density functional theory (DFT/MRCI) to describe transition energies and densities as well as the corresponding excitonic couplings, for the three lowest singlet excited states of nine carotenoids present in three different LH complexes of algae and plants. These benchmark results are used to find an approximated computational approach, which could be used to quantitatively reproduce the key quantities at a reduced computational cost. To this end, we tested the Tamm-Dancoff approximation (TDA) to time-dependent density functional theory in combination with different functionals. By analyzing the errors with respect to DFT/MRCI-TDA results for the full set of electronic properties, we conclude that TDA-TPSS with small basis sets indeed represents an effective approach to investigate LH processes that involve carotenoids.

    The Tamm-Dancoff approximation (TDA), widely used in physics to decouple excitations and de-excitations, is well known to be good for the calculation of excitation energies but not for oscillator strengths. In particular, the sum rule is violated in the latter case. The same concern arises within the TDA in the calculation of nonadiabatic couplings (NACs) by time-dependent density functional theory (TDDFT), due to the similarities in the TDDFT formulations of NACs and oscillator strengths [C. Hu, H. Hirai, and O. Sugino, J. Chem. Phys. 127, 064103 (2007)]. In this study, we present a systematic evaluation of the performance of TDDFT/TDA for the calculation of NACs. In the cases we considered, including a variety of systems possessing Jahn-Teller and Renner-Teller intersections, as well as an example with accidental conical intersections, it is found that the TDDFT/TDA performs better than the full TDDFT, contrary to the conjecture that the TDA might cause the NAC results to deteriorate and violate the sum rule. The surprisingly good performance of the TDA for NACs is probably because the TDA can partially compensate for the local-density-approximation error and give better excitation energies in the vicinity of intersections of potential energy surfaces. Our study also shows that it is important to use the TDA based on the rigorous full-TDDFT formulation of NACs, instead of using it based on an alternative approximate formulation.

    The Tamm-Dancoff approximation (TDA) can be applied to the computation of excitation energies using time-dependent Hartree-Fock (TD-HF) and time-dependent density-functional theory (TD-DFT). In addition to simplifying the resulting response equations, the TDA has been shown to significantly improve the calculation of triplet excitation energies in these theories, largely overcoming issues associated with triplet instabilities of the underlying reference wave functions. Here, we examine the application of the TDA to the calculation of another response property involving triplet perturbations, namely the indirect nuclear spin-spin coupling constant. Particular attention is paid to the accuracy of the triplet spin-dipole and Fermi-contact components. The application of the TDA in HF calculations leads to vastly improved results. For DFT calculations, the TDA delivers improved stability with respect to geometrical variations but does not deliver higher accuracy close to equilibrium geometries. These observations are rationalised in terms of the ground- and excited-state potential energy surfaces and, in particular, the severity of the triplet instabilities associated with each method. A notable feature of the DFT results within the TDA is their similarity across a wide range of different functionals. The uniformity of the TDA results suggests that some conventional evaluations may exploit error cancellations between approximations in the functional forms and those arising from triplet instabilities. The importance of an accurate treatment of correlation for evaluating spin-spin coupling constants is highlighted by this comparison.

  9. Distributional and regularized radiation fields of non-uniformly moving straight dislocations, and elastodynamic Tamm problem

    NASA Astrophysics Data System (ADS)

    Lazar, Markus; Pellegrini, Yves-Patrick

    2016-11-01

    This work introduces original explicit solutions for the elastic fields radiated by non-uniformly moving, straight, screw or edge dislocations in an isotropic medium, in the form of time-integral representations in which acceleration-dependent contributions are explicitly separated out. These solutions are obtained by applying an isotropic regularization procedure to distributional expressions of the elastodynamic fields built on the Green tensor of the Navier equation. The obtained regularized field expressions are singularity-free, and depend on the dislocation density rather than on the plastic eigenstrain. They cover non-uniform motion at arbitrary speeds, including faster-than-wave ones. A numerical method of computation is discussed, that rests on discretizing motion along an arbitrary path in the plane transverse to the dislocation, into a succession of time intervals of constant velocity vector over which time-integrated contributions can be obtained in closed form. As a simple illustration, it is applied to the elastodynamic equivalent of the Tamm problem, where fields induced by a dislocation accelerated from rest beyond the longitudinal wave speed, and thereafter put to rest again, are computed. As expected, the proposed expressions produce Mach cones, the dynamic build-up and decay of which is illustrated by means of full-field calculations.

    Photonic and plasmon-coupled emissions present new opportunities for control on light emission from fluorophores, and have many applications in the physical and biological sciences. The mechanism of and the influencing factors for the coupling between the fluorescent molecules and plasmon and/or photonic modes are active areas of research. In this paper, we describe a hybrid photonic–plasmonic structure that simultaneously contains two plasmon modes: surface plasmons (SPs) and Tamm plasmons (TPs), both of which can modulate fluorescence emission. Experimental results show that both SP-coupled emission (SPCE) and TP-coupled emission (TPCE) can be observed simultaneously with this hybrid structure. Due to the different resonant angles of the TP and SP modes, the TPCE and SPCE can be beamed in different directions and can be separated easily. Back focal plane images of the fluorescence emission show that the relative intensities of the SPCE and TPCE can be changed if the probes are at different locations inside the hybrid structure, which reveals the probe location-dependent different coupling strengths of the fluorescent molecules with SPs and TPs. The different coupling strengths are ascribed to the electric field distribution of the two modes in the structure. Here, we present an understanding of these factors influencing mode coupling with probes, which is vital for structure design for suitable applications in sensing and diagnostics. PMID:26526929

    We have isolated bovine and rodent cDNA and genomic clones encoding the kidney-specific Tamm-Horsfall protein (THP). In both species the gene contains 11 exons, the first of which is noncoding. Exon/intron junctions were analyzed and all were shown to follow the AG/GT rule. A kidney-specific DNase I hypersensitive site was mapped onto a rodent genomic fragment for which the sequence is highly conserved in three species (rat, cow, and human) over a stretch of 350 base pairs. Primer extension and RNase protection analysis identified a transcription start site at the 3' end of this conserved region. A TATA box is located at 32 nucleotides upstream of the start site in the bovine gene and 34 nucleotides upstream in the rodent gene. An inverted CCAAT motif occurs at 65 and 66 nucleotides upstream of the start site in the bovine and rodent genes, respectively. Other highly conserved regions were noted in this 350 bp region and these are likely to be binding sites for transcription factors. A functional assay based on an in vitro transcription system confirmed that the conserved region is an RNA Pol II promoter. The in vitro system accurately initiated transcription from the in vivo start site and was highly sensitive to inhibition by alpha-amanitin at a concentration of 2.5 micrograms/ml. These studies set the stage for the further definition of cis-acting sequences and trans-factors regulating expression of the THP gene, a model for kidney-specific gene expression.

    Tunneling time in attosecond and strong-field experiments is one of the most controversial issues in current research, because of its importance to the theory of time, the time operator and the time–energy uncertainty relation in quantum mechanics. In Kullie (2015 Phys. Rev. A 92 052118) we derived an estimation of the (real) tunneling time, which shows an excellent agreement with the time measured in attosecond experiments, our derivation is found by utilizing the time–energy uncertainty relation, and it represents a quantum clock. In this work, we show different aspects of the tunneling time in attosecond experiments, we discuss and compare the different views and approaches, which are used to calculate the tunneling time, i.e. Keldysh time (as a real or imaginary quantity), Mandelstam–Tamm time, the classical view of the time measurement and our tunneling time relation(s). We draw some conclusions concerning the validity and the relation between the different types of the tunneling time with the hope that they will help to answer the question put forward by Orlando et al (2014 J.

However, as we will see, the important question is a more general one: how to understand the time and the measurement of the time of a quantum system? In respect to our result, the time in quantum mechanics can be, in more general fashion, classified in two types, intrinsic dynamically connected, and external dynamically not connected to the system, and consequently (perhaps only) classical Newtonian time remains as a parametric type of time.

    Optical Tamm states (OTSs) in analogy with its electronic counterpart confined at the surface of crystals are optical surface modes at the interfaces between uniform metallic films and distributed Bragg reflectors. In this paper, OTSs are numerically investigated in two-dimensional hybrid plasmonic-photonic crystal nanobeams (HPPCN), which are constructed by inserting a metallic nanoparticle into a photonic crystal nanobeam formed by periodically etching square air holes into dielectric waveguides. The evidences of OTSs can be verified by transmission spectra and the field distribution at resonant frequency. Similar to OTSs in one-dimensional multilayer structures OTSs in HPPCN can be excited by both TE and TM polarization. The physical origin of OTSs in HPPCN is due to the combined contribution of strong reflection imposed by the photonic band gap (PBG) of the photonic crystal (PC) nanobeam and strong backward scattering exerted by the nanoparticle. For TE, incidence OTSs can be obtained at the frequency near the center of the photonic band gap. The transmissivity and the resonant frequency can be finely tuned by the dimension of nanoparticles. While for TM incidence OTSs are observed for relatively larger metallic nanoparticles compared with TE polarization. The differences between TE and TM polarization can be explained by two reasons. For one reason stronger backward scattering of nanoparticles for TE polarization can be achieved by the excitation of localized surface plasmon polariton of nanoparticles. This assumption has been proved by examining the scattering, absorption, and extinction cross section of the metallic nanoparticle. The other can be attributed to the deep and wide PBG available for TE polarization with less number of air holes compared with TM polarization. Our results show great promise in extending the application scope of OTSs from one-dimensional structures to practical integrated photonic devices and circuits.

  17. Collectivity of the pygmy dipole resonance within schematic Tamm-Dancoff approximation and random-phase approximation models

    Within schematic models based on the Tamm-Dancoff approximation and the random-phase approximation with separable interactions, we investigate the physical conditions that may determine the emergence of the pygmy dipole resonance in the E 1 response of atomic nuclei. By introducing a generalization of the Brown-Bolsterli schematic model with a density-dependent particle-hole residual interaction, we find that an additional mode will be affected by the interaction, whose energy centroid is closer to the distance between two major shells and therefore well below the giant dipole resonance (GDR). This state, together with the GDR, exhausts all the transition strength in the Tamm-Dancoff approximation and all the energy-weighted sum rule in the random-phase approximation. Thus, within our scheme, this mode, which could be associated with the pygmy dipole resonance, is of collective nature. By relating the coupling constants appearing in the separable interaction to the symmetry energy value at and below saturation density we explore the role of density dependence of the symmetry energy on the low-energy dipole response.

    The concentrations and profiles of polycyclic aromatic hydrocarbons were determined in spent drilling fluid deposited at Emu-Uno, Delta State of Nigeria. The total concentrations of polycyclic aromatic hydrocarbons in the spent drilling fluid deposits ranged between 40 and 770 μg kg(-1). The PAHs profile were predominantly 2- and 3-rings with acenaphthalene, phenanthrene, fluorene being the predominant PAHs. The prevalence of 2- and 3-rings PAHs in the spent drilling fluid deposits indicate contamination of the drilling fluids with crude oil during drilling. Incorporation of spent drilling fluids into the soil has serious implication for soil, surface water and groundwater quality.

    The effect of the tracking network on long (greater than 100 km) GPS baseline estimates was estimated using various subsets of the global tracking network initiated by the first Central and South America (CASA Uno) experiment. It was found that best results could be obtained with a global tacking network consisting of three U.S. stations, two sites in the southwestern Pacific, and two sites in Europe. In comparison with smaller subsets, this global network improved the baseline repeatability, the resolution of carrier phase cycle ambiguities, and formal errors of the orbit estimates.

    Examination of new methods of treatment of parodontitis is stipulated by the significant increase in the number of patients with parodontitis. Experiments were conducted on white outbred male rats weighing 150-200 gr, which were divided into three groups. The first group was a reference one (n=20). The second group includes induced parodontitis (n=15) and the third group includes induced parodontitis with the treatment of uno de gato (n=19). We simulated parodontitis in the following way: on the lower nippers in the field of a neck we attached a ligature causing mechanical damage. We used a intramuscular injection of Nembutal as a means of narcotization (0.1 ml-10 g per mass). The present work is dedicated to morphological studies of the structures of damaged parodontium during its treatment with a phyto-preparation uno de gato. The undertaken treatment has demonstrated partial restoration of the mucous tunic of the gum. Newly formed capillaries were found in the connective tissue. The fibroblasts are mostly mature and collagen-producing. Thus, the study has demonstrated that there is a certain tendency of the tissue restoration and the treatment has produced the best therapeutic results. PMID:17660608

    Patients with HT-1 can develop progressive liver disease and have a high incidence of HCC. LT is indicated in patients with fulminant liver failure, HCC or decompensated chronic liver disease refractory to NTBC. To determine the need for LT and outcomes after LT in children with HT-1. Children with HT-1 who had LT between 10/1987 and 5/2008 were identified from the UNOS database. Of 11,467 children in the UNOS database, 125 (1.1%) required LT secondary to HT-1. Mean age at LT was two and half yr (s.d. ± 3.6 yr). Mean age at LT during the first 10 yr of the study (1.82, s.d. ± 2.86 yr) was significantly lower than in the last decade (3.70, s.d. ± 4.42 yr), p = 0.01. Nearly half of the patients (58, 46.4%) were transplanted between 1988 and 1992. Overall, one- and five-yr patient survival was 90.4% and 90.4%, respectively. LT is a valuable option for children with HT-1 with fulminant liver failure or when medical treatment fails. The rate of LT for children with HT-1 has decreased and age at transplant increased over the last decade most probably reflecting the effect of early diagnosis and treatment with NTBC.

    The beginning of the twentieth century saw the emergence of the discipline of genetics. It is striking how many female scientists were contributing to this new field at the time. At least three female pioneers succeeded in becoming professors: Kristine Bonnevie (Norway), Elisabeth Schiemann (Germany) and the Tine Tammes (The Netherlands). The question is which factors contributed to the success of these women's careers? At the time women were gaining access to university education it had become quite the norm for universities to be sites for teaching and research. They were still expanding: new laboratories were being built and new disciplines were being established. All three women benefited from the fact that genetics was considered a new field promising in terms of its utility to society; in the case of Tammes and Schiemann in agriculture and in the case of Bonnevie in eugenics. On the other hand, the field of genetics also benefited from the fact that these first female researchers were eager for the chance to work in science and wanted to make active contributions. The all worked and studied in environments which, although different from one another, were positive towards them, at least at the start. Having a patron was generally a prerequisite. Tammes profited from her teacher's contacts and status. Bonnevie made herself indispensable through her success as a teacher and eventually made her position so strong that she was no longer dependent on a single patron. The case of Schiemann adds something new; it shows the vulnerability of such dependency. Initially, Schiemann's teacher had to rely on the first generation of university women simply because he was unable to attract ambitious young men to his institute. In those early, uncertain years of the new discipline, male scientists tended to choose other, better established, and more prestigious disciplines. However, when genetics itself had become an established field, it also became more attractive to men

    We engaged secondary science students in a teacher and student constructed Uno card game (UCG) to change their conceptual understanding of the various energy transformations. The paper outlines how we incorporated Toulmin’s argumentation pattern (Toulmin 1958 The Uses of Argument (Cambridge: Cambridge University Press)) in the UCG, using discourse (Erduran et al 2004 Sci. Educ. 88 915-33) and through a 5E learning cycle (Bybee 1997 Achieving Scientific Literacy: From Purposes to Practices (Portsmouth, NH: Heinemann Educational Books)). The activity helped students develop a deeper understanding of the energy transformation among and between different sources. Students experienced a conceptual gain in their ways of thinking, in contrast to traditional teaching and learning practices. The collaboration and interaction between teacher-student(s) and between students fostered an environment where they became co-constructors of knowledge.

  7. Some tests of wet tropospheric calibration for the CASA Uno Global Positioning System experiment

    1990-01-01

    Wet tropospheric path delay can be a major error source for Global Positioning System (GPS) geodetic experiments. Strategies for minimizing this error are investigted using data from CASA Uno, the first major GPS experiment in Central and South America, where wet path delays may be both high and variable. Wet path delay calibration using water vapor radiometers (WVRs) and residual delay estimation is compared with strategies where the entire wet path delay is estimated stochastically without prior calibration, using data from a 270-km test baseline in Costa Rica. Both approaches yield centimeter-level baseline repeatability and similar tropospheric estimates, suggesting that WVR calibration is not critical for obtaining high precision results with GPS in the CASA region.

    Unlike the lung allocation score, currently, there is no quantitative scoring system available for patients on heart transplant waiting list. By using United Network for Organ Sharing (UNOS) data, we aim to generate a scoring system based on the recipient and donor risk factors to predict posttransplant survival. Available UNOS data were queried between 2005 and 2013 for heart transplant recipients aged ≥18 years to create separate cox-proportional hazard models for recipient and donor risk scoring. On the basis of risk scores, recipients were divided into five groups and donors into three groups. Kaplan-Meier curves were used for survival. Total 17,131 patients had heart transplant within specified time period. Major factors within high-risk groups were body mass index > 30 kg/m (46%), mean pulmonary artery pressure >30 mmHg (65%), creatinine > 1.5 mg% (63%), bilirubin > 1.5 mg% (54%), noncontinuous-flow left ventricular assist devices (45%) for recipients and gender mismatch (81%) and ischemia time >4 hours (88%) for donors. Survival in recipient groups 1, 2, 3, 4, and 5 at 5 years was 81, 80, 77, 74, and 62%, respectively, and in donor groups 1, 2, and 3 at 5 years was 79, 77, and 70%, respectively (p < 0.001). Combining donor and recipient groups based on scoring showed acceptable survival in low-risk recipients with high-risk donor (75% at 5 years). A higher recipient and donor risk score are associated with worse long-term survival. A low-risk recipient transplanted with high-risk donor has acceptable survival at 5 years, but high-risk recipient combined with a high-risk donor has marginal results. Using an objective scoring system could help get the best results when utilizing high-risk donors. PMID:26771395

    While PhysioNet is a large database for standard clinical vital signs measurements, such a database does not exist for unobtrusively measured signals. This inhibits progress in the vital area of signal processing for unobtrusive medical monitoring as not everybody owns the specific measurement systems to acquire signals. Furthermore, if no common database exists, a comparison between different signal processing approaches is not possible. This gap will be closed by our UnoViS database. It contains different recordings in various scenarios ranging from a clinical study to measurements obtained while driving a car. Currently, 145 records with a total of 16.2 h of measurement data is available, which are provided as MATLAB files or in the PhysioNet WFDB file format. In its initial state, only (multichannel) capacitive ECG and unobtrusive PPG signals are, together with a reference ECG, included. All ECG signals contain annotations by a peak detector and by a medical expert. A dataset from a clinical study contains further clinical annotations. Additionally, supplementary functions are provided, which simplify the usage of the database and thus the development and evaluation of new algorithms. The development of urgently needed methods for very robust parameter extraction or robust signal fusion in view of frequent severe motion artifacts in unobtrusive monitoring is now possible with the database.

    Domestic abuse is widespread and indiscriminate. Older women living with domestic abuse experience a number of health-related concerns and significant mental health issues. Research suggests that the needs of older women experiencing domestic abuse are not being met by existing services. This article examines the issues that older women face as a result of abusive relationships and the barriers to seeking help. Research suggests that a stepped approach, tailored to suit older women's needs, could be beneficial. PMID:27384810

    An enzyme-linked immunosorbent assay (ELISA) has been established using Nunc polystyrene immunoplates coated with a monoclonal antibody to human Tamm-Horsfall urinary glycoprotein (THP) to detect and measure THP in human serum. Optimal reaction conditions for both the monoclonal capture antibody and the affinity-purified rabbit anti-human THP second antibody were established to produce standard curves which showed linearity between 20-90 ng/ml with a sensitivity of 2-3 ng/ml. The plate-to-plate standard curve mean coefficient of variation (CV) was 5.9 +/- 2.9% on assays performed on the same day while day to day mean CV was 13.3 +/- 2.4%. The specificity of the ELISA was demonstrated by inhibition of binding after preincubation of both urinary THP standards and serum with monoclonal anti-THP antibody. Sera from 195 blood donors tested by the ELISA had a mean concentration of THP antigenic determinants of 260 +/- 105 ng/ml. Results from three control sera run on all plates used in the survey showed mean CV less than 7.6% while no binding was observed with sera from an anephric patient.

  12. Direct determination of exciton couplings from subsystem time-dependent density-functional theory within the Tamm-Dancoff approximation

    In subsystem time-dependent density functional theory (TDDFT) [J. Neugebauer, J. Chem. Phys. 126, 134116 (2007), 10.1063/1.2713754] localized excitations are used to calculate delocalized excitations in large chromophore aggregates. We have extended this formalism to allow for the Tamm-Dancoff approximation (TDA). The resulting response equations have a form similar to a perturbative configuration interaction singles (CIS) approach. Thus, the inter-subsystem matrix elements in subsystem TDA can, in contrast to the full subsystem-TDDFT case, directly be interpreted as exciton coupling matrix elements. Here, we present the underlying theory of subsystem TDDFT within the TDA as well as first applications. Since for some classes of pigments, such as linear polyenes and carotenoids, TDA has been reported to perform better than full TDDFT, we also report applications of this formalism to exciton couplings in dimers of such pigments and in mixed bacteriochlorophyll-carotenoid systems. The improved description of the exciton couplings can be traced back to a more balanced description of the involved local excitations.

  13. Schizophrenia in older adults.

    2011-11-01

    Although the number of people older than 55 with schizophrenia is expected to double during the next 20 years, the research data on older adults with schizophrenia are limited. This appears to be because until the middle of the 20th century, it was assumed that mental illness in older adults was a part of the aging process and because older adults are often excluded from research investigations. Nursing research is needed to explore how people with schizophrenia learn to manage their problems as they age, as well as how those who are first diagnosed with schizophrenia in later life adapt to their illness. Mental health nurses need to be cautious in assigning premature labels to older adults with mental illness that may lead to unsubstantiated assumptions about levels of disability. Instead, nurses should realize individual potential regarding undiscovered strengths and should attempt to create interventions that recognize and foster personal development for older adults with schizophrenia.

  15. A simplified Tamm-Dancoff density functional approach for the electronic excitation spectra of very large molecules

    NASA Astrophysics Data System (ADS)

    Grimme, Stefan

    2013-06-01

    Two approximations in the Tamm-Dancoff density functional theory approach (TDA-DFT) to electronically excited states are proposed which allow routine computations for electronic ultraviolet (UV)- or circular dichroism (CD) spectra of molecules with 500-1000 atoms. Speed-ups compared to conventional time-dependent DFT (TD-DFT) treatments of about two to three orders of magnitude in the excited state part at only minor loss of accuracy are obtained. The method termed sTDA ("s" for simplified) employs atom-centered Löwdin-monopole based two-electron repulsion integrals with the asymptotically correct 1/R behavior and perturbative single excitation configuration selection. It is formulated generally for any standard global hybrid density functional with given Fock-exchange mixing parameter ax. The method performs well for two standard benchmark sets of vertical singlet-singlet excitations for values of ax in the range 0.2-0.6. The mean absolute deviations from reference data are only 0.2-0.3 eV and similar to those from standard TD-DFT. In three cases (two dyes and one polypeptide), good mutual agreement between the electronic spectra (up to 10-11 eV excitation energy) from the sTDA method and those from TD(A)-DFT is obtained. The computed UV- and CD-spectra of a few typical systems (e.g., C60, two transition metal complexes, [7]helicene, polyalanine, a supramolecular aggregate with 483 atoms and about 7000 basis functions) compare well with corresponding experimental data. The method is proposed together with medium-sized double- or triple-zeta type atomic-orbital basis sets as a quantum chemical tool to investigate the spectra of huge molecular systems at a reliable DFT level.

    PubMed

    Bannwarth, Christoph; Grimme, Stefan

    2015-04-16

    We show that the electronic circular dichroism (ECD) of delocalized π-systems represents a worst-case scenario for Tamm-Dancoff approximated (TDA) linear response methods. We mainly consider density functional theory (TDA-DFT) variants together with range-separated hybrids, but the conclusions also apply for other functionals as well as the configuration interaction singles (CIS) approaches. We study the effect of the TDA for the computation of ECD spectra in some prototypical extended π-systems. The C76 fullerene, a chiral carbon nanotube fragment, and [11]helicene serve as model systems for inherently chiral, π-chromophores. Solving the full linear response problem is inevitable in order to obtain accurate ECD spectra for these systems. For the C76 fullerene and the nanotube fragment, TDA and CIS approximated methods yield spectra in the origin-independent velocity gauge formalism of incorrect sign which would lead to the assignment of the opposite (wrong) absolute configuration. As a counterexample, we study the ECD of an α-helix polypeptide chain. Here, the lowest-energy transitions are dominated by localized excitations within the individual peptide units, and TDA methods perform satisfactorily. The results may have far-reaching implications for simple semiempirical methods which often employ TDA and CIS for huge molecules. Our recently presented simplified time-dependent DFT approach proves to be an excellent low-cost linear response method which together with range-separated density functionals like ωB97X-D3 produces ECD spectra in very good agreement with experiment.

    Tamm-Horsfall glycoprotein (THGP) or Uromodulin is a membrane protein exclusively expressed along the thick ascending limb (TAL) and early distal convoluted tubule (DCT) of the nephron. Mutations in the THGP encoding gene result in Familial Juvenile Hyperuricemic Nephropathy (FJHN), Medullary Cystic Kidney Disease type 2 (MCKD-2), and Glomerulocystic Kidney Disease (GCKD). The physicochemical and biological properties of THGP have been studied extensively, but its physiological function in the TAL remains obscure. We performed yeast two-hybrid screening employing a human kidney cDNA library and identified THGP as a potential interaction partner of the renal outer medullary potassium channel (ROMK2), a key player in the process of salt reabsorption along the TAL. Functional analysis by electrophysiological techniques in Xenopus oocytes showed a strong increase in ROMK current amplitudes when co-expressed with THGP. The effect of THGP was specific for ROMK2 and did not influence current amplitudes upon co-expression with Kir2.x, inward rectifier potassium channels related to ROMK. Single channel conductance and open probability of ROMK2 were not altered by co-expression of THGP, which instead increased surface expression of ROMK2 as determined by patch clamp analysis and luminometric surface quantification, respectively. Despite preserved interaction with ROMK2, disease-causing THGP mutants failed to increase its current amplitude and surface expression. THGP(-/-) mice exhibited increased ROMK accumulation in intracellular vesicular compartments when compared with WT animals. Therefore, THGP modulation of ROMK function confers a new role of THGP on renal ion transport and may contribute to salt wasting observed in FJHN/MCKD-2/GCKD patients. PMID:21081491

    The acid-base buffer capacity before and after the treatment with the Mehra-Jackson and Tamm reagents was assessed by continuous potentiometric titration for the main genetic horizons of two profiles of podzolic soils in the Central Forest State Reserve. The total buffer capacity was calculated in the pH range from the initial titration point (ITP) to 3 for the acid titration and from the ITP to 10 for the base titration, as well as the buffer capacities in the pH intervals of 0.25. It was found that both treatments abruptly decreased the base buffer capacity, which reached 70-90% in the E horizons. The high direct linear correlation of the difference between the total base buffer capacities before and after each treatment with the content of Fe in the Tamm extract was revealed. From the results obtained, a conclusion was drawn that finely dispersed Fe hydroxides were the main solid-phase constituents ensuring the base buffer capacity, and the deprotonation of hydroxyl groups on the surface of Fe hydroxides was the essential buffer reaction during the base titration.

    Despite a high prevalence of pancreatic endocrine and exocrine insufficiency in cystic fibrosis (CF), pancreas transplantation is rarely reported. United Network for Organ Sharing (UNOS) data were used to examine utilization of pancreas transplant and posttransplant outcomes in CF patients. Between 1987-2014, CF patients (N = 4600) underwent 17 liver-pancreas, three lung-pancreas, one liver-lung pancreas, four kidney-pancreas, and three pancreas-only transplants. Of the 303 CF patients who received liver transplantation, 20% had CF-related diabetes (CFRD) before transplantation, and nine of those received a liver-pancreas transplant. Of 4241 CF patients who underwent lung transplantation, 33% had CFRD before transplantation, and three of those received a pancreas transplant. Of 49 CF patients who received a liver-lung transplant, 57% had CFRD before transplantation and one received a pancreas transplant. Posttransplantation diabetes developed in 7% of CF pancreas transplant recipients versus 24% of CF liver and 29% of CF lung recipients. UNOS has no data on pancreas exocrine insufficiency. Two-year posttransplantation survival was 88% after liver-pancreas transplant, 33% after lung-pancreas transplant, and 100% after pancreas-kidney and pancreas-only transplants. Diabetes is common pretransplantation and posttransplantation in CF solid organ transplant recipients, but pancreas transplantation remains rare. Further consideration of pancreas transplant in CF patients undergoing other solid organ transplant may be warranted.

    More adults aged 65 and older will be driving in the next few decades. Many older drivers are safe behind the wheel and do not need intensive testing for license renewal. Others, however, have physiologic or cognitive impairments that can affect their mobility and driving safety. When an older patient's driving competency is questioned, a comprehensive, step-by-step assessment is recommended. Many diseases that impair driving ability can be detected and treated effectively by family physicians. Physicians should take an active role in assessing and reducing the risk for injury in a motor vehicle and, when possible, prevent or delay driving cessation in their patients. Referral to other health care professionals, such as an occupational or physical therapist, may be helpful for evaluation and treatment. When an older patient is no longer permitted or able to drive, the physician should counsel the patient about using alternative methods of transportation. PMID:10643955

    Organic semiconductors have attracted attention due to their potential for optoelectronics and novel phenomena, such as singlet fission. Here, we use many-body perturbation theory to simulate neutral excitations in acene and perylene crystals. By diagonalizing the full Bethe-Salpether (BSE) Hamiltonian beyond the Tamm Dancoff approximation (TDA), we find that both low-lying excitation energies and oscillator strengths are in improved agreement with experiments relative to the TDA. We characterize the low-lying excitons, focusing in the degree of charge-transfer and spatial delocalization, connecting their relevance to singlet fission. For perylene, we find overall good agreement with absorption measurements, and we see evidence for the formation of an ``exciton-polariton'' band in β-perylene. This work is supported by the DOE.

    We report on the enhancement of the spontaneous emission in the visible red spectral range from site-controlled InP/GaInP quantum dots by resonant coupling to Tamm-plasmon modes confined beneath gold disks in a hybrid metal/semiconductor structure. The enhancement of the emission intensity is confirmed by spatially resolved micro-photoluminescence area scans and temperature dependent measurements. Single photon emission from our coupled system is verified via second order autocorrelation measurements. We observe bright single quantum dot emission of up to ∼173 000 detected photons per second at a repetition rate of the excitation source of 82 MHz, and calculate an extraction efficiency of our device as high as 7%.

    Equal or comparable contents of Fe and Al extractable by Tamm and Mehra-Jackson solutions have been revealed in all the horizons of a loamy mucky-peaty-podzolic gley soil on binary deposits. The content of Si extractable by the Mehra-Jackson solution has exceeded that of oxalate-soluble Si by an order of magnitude. The distributions of Al in the Tamm solutions from the entire soil and its fractions of 1-5 and >5 μm are of accumulative type with a maximum in the mucky H horizon and a gradual decrease of the content with depth in relation with the analogous distribution of Al-organic complexes. The maximum content of oxalate-soluble Al in the clay fraction has been found in the eluvial ELg horizon, which can be due to the partial dissolution of Al hydroxide interlayers in soil chlorites. The distribution of Fe in the entire soil has two maximums, in the H horizon due to the accumulation of Fe-organic complexes and in the concretion-rich ELnn,g horizon due to the accumulation of Fe hydroxides. Depletion of oxalate-soluble Fe in the eluvial ELg horizon has been observed in all the fractions, which can be related to its mobilization and removal under strongly acidic conditions and the development of reductive processes, as well as the enrichment of the concretion-rich horizon with these compounds because of an increase in pH and the development of conditions favorable for water stagnation and Fe segregation.

    About one person in eight remains employed past 65, the average age for retirement in the U.S. These persons tend to be highly reliable. They can adapt and learn new technology, but may require extra time to do so. Older workers have particular needs in the workplace due to physiological changes that accompany aging. They may require more lighting, and they may have decreased mobility, physical strength, and dexterity. These factors often have no impact on their ability to accomplish job duties. This chapter underscores the significant contributions that older workers often provide, and also addresses retirement planning.

    Depression is less prevalent among older adults than among younger adults but can have serious consequences. Over half of cases represent a first onset in later life. Although suicide rates in the elderly are declining, they are still higher than in younger adults and more closely associated with depression. Depressed older adults are less likely to endorse affective symptoms and more likely to display cognitive changes, somatic symptoms, and loss of interest than are younger adults. Risk factors leading to the development of late life depression likely comprise complex interactions among genetic vulnerabilities, cognitive diathesis, age-associated neurobiological changes, and stressful events. Insomnia is an often overlooked risk factor for late life depression. We suggest that a common pathway to depression in older adults, regardless of which predisposing risks are most prominent, may be curtailment of daily activities. Accompanying self-critical thinking may exacerbate and maintain a depressed state. Offsetting the increasing prevalence of certain risk factors in late life are age-related increases in psychological resilience. Other protective factors include higher education and socioeconomic status, engagement in valued activities, and religious or spiritual involvement. Treatments including behavioral therapy, cognitive behavioral therapy, cognitive bibliotherapy, problem-solving therapy, brief psychodynamic therapy, and life review/reminiscence therapy are effective but too infrequently used with older adults. Preventive interventions including education for individuals with chronic illness, behavioral activation, cognitive restructuring, problem-solving skills training, group support, and life review have also received support.

    The versatility, simplicity, and robustness of Arduino microcontroller architecture have won a huge following with increasingly serious engineering and physical science applications. Arduino microcontroller environment coupled with commercially available sensors have been used to systematically measure, record, and analyze low currents, low voltages and corresponding dissipated power for assessing secondary physical properties in a diverse array of engineering systems. Setup was assembled via breadboard, wire, and simple soldering with an Arduino Uno with ATmega328P microcontroller connected to a PC. The microcontroller was programmed with Arduino Software while the bootloader was used to upload the code. Commercial Hall effect current sensor modules ACS712 and INA169 current shunt monitor was used to measure corresponding low to ultra-low currents and voltages. Stable measurement data was obtained via sensors and compared with corresponding oscilloscope measurements to assess reliability and uncertainty. Sensor breakout boards were modified to enhance the sensitivity of the measurements and to expand the applicability. Discussion of these measurements will focus on capabilities, capacities and limitations of the systems with examples of possible applications. Lock Haven Nanotechnology Program.

  5. Protein and older adults.

    PubMed

    Chernoff, Ronni

    2004-12-01

    Body composition changes as people get older. One of the noteworthy alterations is the reduction in total body protein. A decrease in skeletal muscle is the most noticeable manifestation of this change but there is also a reduction in other physiologic proteins such as organ tissue, blood components, and immune bodies as well as declines in total body potassium and water. This contributes to impaired wound healing, loss of skin elasticity, and an inability to fight infection. The recommended dietary allowance (RDA) for adults for protein is 0.8 grams of protein per kilogram of body weight. Protein tissue accounts for 30% of whole-body protein turnover but that rate declines to 20% or less by age 70. The result of this phenomenon is that older adults require more protein/kilogram body weight than do younger adults. Recently, it has become clear that the requirement for exogenous protein is at least 1.0 gram/kilogram body weight. Adequate dietary intake of protein may be more difficult for older adults to obtain. Dietary animal protein is the primary source of high biological value protein, iron, vitamin B(12), folic acid, biotin and other essential nutrients. In fact, egg protein is the standard against which all other proteins are compared. Compared to other high-quality protein sources like meat, poultry and seafood, eggs are the least expensive. The importance of dietary protein cannot be underestimated in the diets of older adults; inadequate protein intake contributes to a decrease in reserve capacity, increased skin fragility, decreased immune function, poorer healing, and longer recuperation from illness.

    Rhinitis symptoms of rhinorrhea, congestion, sneezing, nasal/ocular pruritis, and postnasal drainage can significantly affect the quality of life for older adults. As the US population ages, it will be increasingly important for health-care providers to effectively diagnose and manage rhinitis. Rhinitis is categorized broadly into allergic rhinitis and non-allergic rhinitis. Environmental changes and avoidance measures are a primary means of intervention. In addition, there are several topical therapies (nasal sprays) that can be effective for symptom control.

    Background Previous multivariate analysis during 4/1/94-12/31/00 from the Organ Procurement Transplant Network/United Network for Organ Sharing (OPTN/UNOS) database has shown that kidneys from Black donors were associated with lower graft survival. We compared graft and patient survival of different kidney donor-to-recipient ethnic combinations to see if this result still holds on a recent cohort of US kidney transplants. Methods 72,495 recipients of deceased and living donor kidney alone transplants from 2001-2005 were included. A multivariate Cox regression method was used to analyze the effect of donor-recipient ethnicity on graft and patient survival within 5 years of transplant, and to adjust for the effect of other donor, recipient and transplant characteristics. Results are presented as hazard ratios (HR) with the 95% confidence limit (CL) and p-values. Results Adjusted HR's of donor-recipient patient survival: White to White (1), White to Black (1.22, p=.001). Graft survival HRS: Black to Black (1.40, p<0.001), Black to White (1.35, p<0.001), Black to Hispanic (0.87, p=0.18), Black to Asian (0.69, p=0.05). Summary Black donor Kidneys are associated with significantly lower graft survival when transplanted into Whites and Blacks and are only associated with lower patient survival when these kidneys are transplanted into White transplant recipients. The graft and patient survival rates for Asian and Latino/Hispanic recipients however were not affected by donor ethnicity. This analysis underscores the need for research to better understand the reasons for these disparities and how to improve the post transplant graft survival rates of Blacks. PMID:20005353

    The computational bottleneck of the extremely fast simplified Tamm-Dancoff approximated (sTDA) time-dependent density functional theory procedure [S. Grimme, J. Chem. Phys. 138, 244104 (2013)] for the computation of electronic spectra for large systems is the determination of the ground state Kohn-Sham orbitals and eigenvalues. This limits such treatments to single structures with a few hundred atoms and hence, e.g., sampling along molecular dynamics trajectories for flexible systems or the calculation of chromophore aggregates is often not possible. The aim of this work is to solve this problem by a specifically designed semi-empirical tight binding (TB) procedure similar to the well established self-consistent-charge density functional TB scheme. The new special purpose method provides orbitals and orbital energies of hybrid density functional character for a subsequent and basically unmodified sTDA procedure. Compared to many previous semi-empirical excited state methods, an advantage of the ansatz is that a general eigenvalue problem in a non-orthogonal, extended atomic orbital basis is solved and therefore correct occupied/virtual orbital energy splittings as well as Rydberg levels are obtained. A key idea for the success of the new model is that the determination of atomic charges (describing an effective electron-electron interaction) and the one-particle spectrum is decoupled and treated by two differently parametrized Hamiltonians/basis sets. The three-diagonalization-step composite procedure can routinely compute broad range electronic spectra (0-8 eV) within minutes of computation time for systems composed of 500-1000 atoms with an accuracy typical of standard time-dependent density functional theory (0.3-0.5 eV average error). An easily extendable parametrization based on coupled-cluster and density functional computed reference data for the elements H-Zn including transition metals is described.

    This qualitative study was designed to identify and describe characteristics of successfully adjusted older women. The participants reported a recent major loss and were considered successfully adjusted as evidenced by social involvement in a senior center, a mid level to high level of morale and self-report. Using a grounded theory approach, five underlying themes were identified: equanimity, self-reliance, existential aloneness, perseverance and meaningfulness. These themes are thought to constitute resilience. Lateral grounding of the concept resilience is accomplished by comparison with philosophical writings of Frankl, Bettelheim, Frank, May and von Witzleben. Resilience is important in late life as a component of successful psychosocial adjustment. PMID:2292448

    Using data collected from 1,906 RNs from Metropolitan Statistical Areas in 29 states, the purpose of this study was to examine the characteristics and work attitudes of older RNs compared to RNs less than age 50 at two time periods, and compare among the older RNs those who are working in nursing, working outside nursing, and not working. Older RNs reported more distributive justice (fairness of rewards), work group cohesion, and supervisory support and less organizational constraint, and quantitative workload than younger RNs. Overall, older RNs were more satisfied, had greater organizational commitment, and had less desire to quit than younger RNs. There were no significant differences between older and younger RNs for autonomy, mentor support, or variety. Strategic efforts by employers and government could be used to retain older workers, attract RNs working in nonnursing settings back into nursing, and recruit retired RNs into the nursing workforce.

    1993-05-01

    As concern increases about the safety of the aging driver, it is clear that the principal goal of assessment is to identify the unsafe driver and provide effective medical and rehabilitative services to enable the resumption of safe driving. When adequate restorative therapy is not possible, it is necessary to restrict or revoke the privilege of driving. Assessment also can reassure the safe older driver that he or she can continue operating a motor vehicle without restrictions. The process of assessing the older driver is best accomplished through the collaboration of health professionals and governmental agencies. The former identify and treat, if possible, medical conditions that may pose threats to safe driving; the latter establish guidelines of competency for driving tasks. These roles are complementary, although the settings and methods for these assessments are different. Moreover, the responsibilities of the physician and other health care professionals extend beyond the decision regarding driving and must consider the individual needs for driving, as well as the ramifications associated with its cessation.

    We derived the analytic gradient for the excitation energies from a time-dependent density functional theory calculation within the Tamm-Dancoff approximation (TDDFT/TDA) using Gaussian atomic orbital basis sets, and introduced an efficient serial and parallel implementation. Some timing results are shown from a B3LYP/6-31G**/SG-1-grid calculation on zincporphyrin. We also performed TDDFT/TDA geometry optimizations for low-lying excited states of 20 small molecules, and compared adiabatic excitation energies and optimized geometry parameters to experimental values using the B3LYP and ωB97 functionals. There are only minor differences between TDDFT and TDA optimized excited state geometries and adiabatic excitation energies. Optimized bond lengths are in better agreement with experiment for both functionals than either CC2 or SOS-CIS(D0), while adiabatic excitation energies are in similar or slightly poorer agreement. Optimized bond angles with both functionals are more accurate than CIS values, but less accurate than either CC2 or SOS-CIS(D0) ones.

    2012-01-01

    Although few organ systems play a more important role than the kidneys in cytokine catabolism, the mechanism(s) regulating this pivotal physiological function and how its deficiency affects systemic cytokine homeostasis remain unclear. Here we show that elimination of Tamm-Horsfall protein (THP) expression from mouse kidneys caused a marked elevation of circulating IFN-γ, IL1α, TNF-α, IL6, CXCL1, and IL13. Accompanying this were enlarged spleens with prominent white-pulp macrophage infiltration. Lipopolysaccharide (LPS) exacerbated the increase of serum cytokines without a corresponding increase in their urinary excretion in THP knock-out (KO) mice. This, along with the rise of serum cystatin C and the reduced inulin and creatinine clearance from the circulation, suggested that diminished glomerular filtration may contribute to reduced cytokine clearance in THP KO mice both at the baseline and under stress. Unlike wild-type mice where renal and urinary cytokines formed specific in vivo complexes with THP, this “trapping” effect was absent in THP KO mice, thus explaining why cytokine signaling pathways were activated in renal epithelial cells in such mice. Our study provides new evidence implicating an important role of THP in influencing cytokine clearance and acting as a decoy receptor for urinary cytokines. Based on these and other data, we present a unifying model that underscores the role of THP as a major regulator of renal and systemic immunity. PMID:22451664

    In this study, the specificity, sensitivity, and operability of RSID™-Urine, a new immunochromatographic test for urine identification, was evaluated and compared with ELISA detection of Tamm-Horsfall protein (THP). Urine was successfully identified among other body fluids using RSID™-Urine and ELISA detection of THP. The detection limit of RSID™-Urine equated to 0.5 μL of urine; although the sensitivity of RSID™-Urine may be lower than that of ELISA detection of THP, it is thought to be sufficient for application to casework samples. However, results from RSID™-Urine must be interpreted with caution when the sample may have been contaminated with blood or vaginal fluid, because this might inhibit urine detection. The RSID™-Urine assay can be performed in just 15 min by dropping the extracted sample onto the test cassette. Therefore, RSID™-Urine should be an effective tool for the forensic identification of urine, in addition to ELISA detection of THP.

Of the native and asialo Sd(a+) and Sd(a-) THGP tested by QPA and ELLSA, only native and asialo Sd(a+) bound well with Dolichos biflorus (DBA) and Vicia villosa-B4 (VVA-B4), while Sd(a-) THGP reacted poorly with these two lectins. Neither Sd(a+) nor Sd(a-) THGPs reacted with two other GalNAc alpha-anomer specific lectins: Codium fragile subspecies tomentosoides and Artocarpus integrifolia. Furthermore, the binding of asialo Sd(a+)THGP-VVA-B4 and native Sd(a+)THGP-DBA through GalNAc beta--> was confirmed by inhibition assay. These results demonstrate that DBA and VVA-B4 are useful reagents to differentiate between Sd(a+) and Sd(a-) THGP.

    The first goal of this study is to see if social relationships in the church influence feelings of gratitude toward God. The second goal is to assess the impact of race and ethnicity on this relationship. The data support the following hypotheses: (1) older people who go to church more often tend to receive more spiritual support from fellow church members; (2) older adults who receive more spiritual support at church will derive a deeper understanding of themselves and others; (3) older people who develop greater insight into themselves and others will derive a greater sense of religious meaning in life; and (4) older adults who develop a deeper sense of religious meaning in life will feel more grateful to God. The results also indicate that the study model explains how feelings of gratitude toward God arise among older blacks and whites, but not older Mexican Americans. PMID:23543840

    1987-11-01

    1. A role has been suggested for anti-Tamm-Horsfall protein (THP) antibodies in renal disease based on the results of immunoassays of pathological sera. The putative autoantibodies have not been isolated from such sera nor have definitive inhibition studies of their binding been carried out. We have carried out such studies using rabbit anti-THP antibodies as control reagents. 2. Urinary THP prepared by salt precipitation was used to prepare four immunoabsorbent columns by covalent coupling to CNBr-activated Sepharose 4B. After washing with a variety of dissociating agents to remove any non-covalently bound subunit THP, each column was incubated with normal and immune rabbit serum. Fractions washed and eluted from columns were tested for anti-THP antibodies by enzyme-linked immunosorbent assay (ELISA) and THP antigen by radioimmunoassay, and showed NH4SCN (3 mol/l) and guanidine hydrochloride (GuHCl) (6 mol/l) equivalent and sodium dodecyl sulphate (20 g/l) to be inferior in their capacity to produce immunoabsorbent THP capable of isolating specific antibodies from immune rabbit serum. 3. The column treated with GuHCl (6 mol/l) was used further in attempts to isolate putative anti-THP antibodies from five patients, who had a history of urinary tract infections and whose sera showed strong binding by ELISA. 4. Results from direct and inhibition ELISA experiments on fractions collected after washing and elution with all sera suggested that the putative human anti-THP antibodies were of very low affinity and/or directed against non-subunit THP. 5. The pathological relevance of human anti-THP antibodies measured by ELISA remains to be established.

    We present a solution of the full time-dependent density-functional theory (TDDFT) eigenvalue equation in the linear response formalism exhibiting a linear-scaling computational complexity with system size, without relying on the simplifying Tamm-Dancoff approximation (TDA). The implementation relies on representing the occupied and unoccupied subspaces with two different sets of in situ optimised localised functions, yielding a very compact and efficient representation of the transition density matrix of the excitation with the accuracy associated with a systematic basis set. The TDDFT eigenvalue equation is solved using a preconditioned conjugate gradient algorithm that is very memory-efficient. The algorithm is validated on a small test molecule and a good agreement with results obtained from standard quantum chemistry packages is found, with the preconditioner yielding a significant improvement in convergence rates. The method developed in this work is then used to reproduce experimental results of the absorption spectrum of bacteriochlorophyll in an organic solvent, where it is demonstrated that the TDA fails to reproduce the main features of the low energy spectrum, while the full TDDFT equation yields results in good qualitative agreement with experimental data. Furthermore, the need for explicitly including parts of the solvent into the TDDFT calculations is highlighted, making the treatment of large system sizes necessary that are well within reach of the capabilities of the algorithm introduced here. Finally, the linear-scaling properties of the algorithm are demonstrated by computing the lowest excitation energy of bacteriochlorophyll in solution. The largest systems considered in this work are of the same order of magnitude as a variety of widely studied pigment-protein complexes, opening up the possibility of studying their properties without having to resort to any semiclassical approximations to parts of the protein environment.

    Even though computers play a massive role in everyday life of modern societies, older adults, and especially older women, are less likely to use a computer, and they perform fewer activities on it than younger adults. To get a better understanding of the factors affecting older adults' intention towards and usage of computers, the Unified Theory of Acceptance and Usage of Technology (UTAUT) was applied as part of a more extensive study with 52 users and non-users of computers, ranging in age from 50 to 90 years. The model covers various aspects of computer usage in old age via four key constructs, namely performance expectancy, effort expectancy, social influences, and facilitating conditions, as well as the variables gender, age, experience, and voluntariness it. Interestingly, next to performance expectancy, facilitating conditions showed the strongest correlation with use as well as with intention. Effort expectancy showed no significant correlation with the intention of older adults to use a computer.

    2016-09-01

    The biology of aging and the pathophysiology of cardiovascular disease (CVD) overlap, with the effect that CVD is endemic in the growing population of older adults. Moreover, CVD in older adults is usually complicated by age-related complexities, including multimorbidity, polypharmacy, frailty, and other intricacies that add to the risks of ambiguous symptoms, deconditioning, iatrogenesis, falls, disability, and other challenges. Cardiac rehabilitation (CR) is a comprehensive lifestyle program that can have particular benefit for older patients with cardiovascular conditions. Although CR was originally designed primarily as an exercise training program for younger adults after a myocardial infarction or coronary artery bypass surgery, it has evolved as a comprehensive lifestyle program (promoting physical activity as well as education, diet, risk reduction, and adherence) for a broader range of CVD (coronary heart disease, heart failure, and valvular heart disease). It provides a valuable opportunity to address and moderate many of the challenges pertinent for the large and growing population of older adults with CVD. Cardiac rehabilitation promotes physical function (cardiorespiratory fitness as well as strength and balance) that helps overcome disease and deconditioning as well as related vulnerabilities such as disability, frailty, and falls. Similarly, CR facilitates education, monitoring, and guidance to reduce iatrogenesis and promote adherence. Furthermore, CR fosters cognition, socialization, and independence in older patients. Yet despite all its conceptual benefits, CR is significantly underused in older populations. This review discusses benefits and the paradoxical underuse of CR, as well as evolving models of care that may achieve greater application and efficacy. PMID:27297002

  5. Weight Management in Older Adults.

    2015-09-01

    As the number of older adults increases rapidly, the national epidemic of obesity is also affecting our aging population. This is particularly concerning given the numerous health risks and increased costs associated with this condition. Weight management is extremely important for older adults given the risks associated with abdominal adiposity, which is a typical fat redistribution during aging, and the prevalence of comorbid conditions in this age group. However, approaches to weight loss must be considered critically given the dangers of sarcopenia (a condition that occurs when muscle mass and quality are lost), the increased risk of hip fracture with weight loss, and the association between reduced mortality and increased BMI in older adults. This overview highlights the challenges and implications of measuring adiposity in older adults and the dangers and benefits of weight loss in this population and provides an overview of the new Medicare Obesity Benefit. In addition, we provide a summary of outcomes from successful weight loss interventions for older adults and discuss implications for advancing clinical practice. PMID:26627496

    2004-01-01

    In the U.S. as well as other countries, the number of motorcyclists killed in traffic crashes has risen sharply over the past five years, due in part to the increased popularity of motorcycling among older riders. This paper examines trends in motorcyclist casualties and vehicle registrations from 1990–2002, based on national and state (North Carolina) motor vehicle crash and vehicle registration data. The data show similar patterns of increased fatalities that parallel a growth in motorcycle registrations. Whereas the number of motorcyclists ages 16–24 declined over the 13–year study period, the number of riders ages 35 and older increased. Three years of recent (2000–2002) NC data are examined to identify salient characteristics of the crashes of these older riders. Results are discussed with respect to approaches for mitigating the increase in motorcyclist deaths and injuries. PMID:15319126

    Vaccine response declines with age, but currently recommended vaccines are safe and effective in reducing, if not preventing, disease altogether. Over the last decade, advancements in vaccine immunogenicity, either by increasing dose or conjugating vaccines to protein, have resulted in more immunogenic vaccines that also seem more effective in reducing clinical disease both for influenza and pneumococcus. Meanwhile, there is a resurgence in incident pertussis, exceeding prevalence from five decades ago, adding older adults to a recommended target vaccination group. This article discusses currently available vaccines, in the context of current epidemiology and recommendations, for older adults. PMID:27394026

Increasing age and cognitive impairment are risk factors for undertreatment of persistent pain. Safe and effective therapy is available for pain syndromes that commonly affect older adults. Recognition of failure of health providers to appropriately assess and manage persistent pain has led to the recent development and adoption of regulatory guidelines for the implementation of effective pain management programs.

  10. Hearing loss in older adults.

    PubMed

    Walling, Anne D; Dickson, Gretchen M

    2012-06-15

    Hearing loss affects approximately one-third of adults 61 to 70 years of age and more than 80 percent of those older than 85 years. Men usually experience greater hearing loss and have earlier onset compared with women. The most common type is age-related hearing loss; however, many conditions can interfere with the conduction of sound vibrations to the inner ear and their conversion to electrical impulses for conduction to the brain. Screening for hearing loss is recommended in adults older than 50 to 60 years. Office screening tests include the whispered voice test and audioscopy. Older patients who admit to having difficulty hearing may be referred directly for audiometry. The history can identify risk factors for hearing loss, especially noise exposure and use of ototoxic medications. Examination of the auditory canal and tympanic membrane can identify causes of conductive hearing loss. Audiometric testing is required to confirm hearing loss. Adults presenting with idiopathic sudden sensorineural hearing loss should be referred for urgent assessment. Management of hearing loss is based on addressing underlying causes, especially obstructions (including cerumen) and ototoxic medications. Residual hearing should be optimized by use of hearing aids, assistive listening devices, and rehabilitation programs. Surgical implants are indicated for selected patients. Major barriers to improved hearing in older adults include lack of recognition of hearing loss; perception that hearing loss is a normal part of aging or is not amenable to treatment; and patient nonadherence with hearing aids because of stigma, cost, inconvenience, disappointing initial results, or other factors.

  19. Lead toxicity in older adults.

    PubMed

    Vig, E K; Hu, H

    2000-11-01

    Recent studies have shown that lead, even at relatively low levels of exposure, has the potential to harm not only the young and the occupationally-exposed, but also older people. Because they have been alive for a longer period of time, older adults have had more potential exposures to lead. They may have been exposed to lead while working in unregulated occupations, or they may have encountered more lead in the environment on a daily basis. Several large epidemiological studies have found that older people have higher blood and bone lead levels than younger adults. Additionally, sporadic clusters of acute lead exposure among older adults as a result of activities such as ceramic glaze hobby work and consumption of moonshine whiskey continue to be reported. After lead enters the body, it circulates in the blood reaching the soft tissues and bone. Researchers have learned that lead can hibernate within bone for decades. Although lead within bone is of uncertain toxicity to bone tissue, conditions of bone resorption, such as osteoporosis, can cause bone lead to reenter the bloodstream where it can then re-expose the soft tissue, and, potentially, exert delayed deleterious effects. Evidence is emerging that blood and bone lead levels, reflecting relatively modest exposures, are associated with hypertension, renal insufficiency, and cognitive impairment. Medical treatments that now exist to slow the rate of bone resorption may maintain lead within bones. On-going studies evaluating the relationship between body lead stores and both cognitive and renal impairment, as well as the potential modifying effect of bone resorption, will help determine whether bone resorption should be retarded specifically to preserve organ function. Physicians should be aware of potential past and present lead exposures among their older patients. Ongoing lead exposure should be prevented. In the future, treatment of osteoporosis may be undertaken not only to improve bone health but also to

    Vision loss affects 37 million Americans older than 50 years and one in four who are older than 80 years. The U.S. Preventive Services Task Force concludes that current evidence is insufficient to assess the balance of benefits and harms of screening for impaired visual acuity in adults older than 65 years. However, family physicians play a critical role in identifying persons who are at risk of vision loss, counseling patients, and referring patients for disease-specific treatment. The conditions that cause most cases of vision loss in older patients are age-related macular degeneration, glaucoma, ocular complications of diabetes mellitus, and age-related cataracts. Vitamin supplements can delay the progression of age-related macular degeneration. Intravitreal injection of a vascular endothelial growth factor inhibitor can preserve vision in the neovascular form of macular degeneration. Medicated eye drops reduce intraocular pressure and can delay the progression of vision loss in patients with glaucoma, but adherence to treatment is poor. Laser trabeculoplasty also lowers intraocular pressure and preserves vision in patients with primary open-angle glaucoma, but long-term studies are needed to identify who is most likely to benefit from surgery. Tight glycemic control in adults with diabetes slows the progression of diabetic retinopathy, but must be balanced against the risks of hypoglycemia and death in older adults. Fenofibrate also slows progression of diabetic retinopathy. Panretinal photocoagulation is the mainstay of treatment for diabetic retinopathy, whereas vascular endothelial growth factor inhibitors slow vision loss resulting from diabetic macular edema. Preoperative testing before cataract surgery does not improve outcomes and is not recommended. PMID:27479624

    Recent studies have shown that lead, even at relatively low levels of exposure, has the potential to harm not only the young and the occupationally-exposed, but also older people. Because they have been alive for a longer period of time, older adults have had more potential exposures to lead. They may have been exposed to lead while working in unregulated occupations, or they may have encountered more lead in the environment on a daily basis. Several large epidemiological studies have found that older people have higher blood and bone lead levels than younger adults. Additionally, sporadic clusters of acute lead exposure among older adults as a result of activities such as ceramic glaze hobby work and consumption of moonshine whiskey continue to be reported. After lead enters the body, it circulates in the blood reaching the soft tissues and bone. Researchers have learned that lead can hibernate within bone for decades. Although lead within bone is of uncertain toxicity to bone tissue, conditions of bone resorption, such as osteoporosis, can cause bone lead to reenter the bloodstream where it can then re-expose the soft tissue, and, potentially, exert delayed deleterious effects. Evidence is emerging that blood and bone lead levels, reflecting relatively modest exposures, are associated with hypertension, renal insufficiency, and cognitive impairment. Medical treatments that now exist to slow the rate of bone resorption may maintain lead within bones. On-going studies evaluating the relationship between body lead stores and both cognitive and renal impairment, as well as the potential modifying effect of bone resorption, will help determine whether bone resorption should be retarded specifically to preserve organ function. Physicians should be aware of potential past and present lead exposures among their older patients. Ongoing lead exposure should be prevented. In the future, treatment of osteoporosis may be undertaken not only to improve bone health but also to

  17. Hearing loss in older adults.

    PubMed

    Walling, Anne D; Dickson, Gretchen M

    2012-06-15

    Hearing loss affects approximately one-third of adults 61 to 70 years of age and more than 80 percent of those older than 85 years. Men usually experience greater hearing loss and have earlier onset compared with women. The most common type is age-related hearing loss; however, many conditions can interfere with the conduction of sound vibrations to the inner ear and their conversion to electrical impulses for conduction to the brain. Screening for hearing loss is recommended in adults older than 50 to 60 years. Office screening tests include the whispered voice test and audioscopy. Older patients who admit to having difficulty hearing may be referred directly for audiometry. The history can identify risk factors for hearing loss, especially noise exposure and use of ototoxic medications. Examination of the auditory canal and tympanic membrane can identify causes of conductive hearing loss. Audiometric testing is required to confirm hearing loss. Adults presenting with idiopathic sudden sensorineural hearing loss should be referred for urgent assessment. Management of hearing loss is based on addressing underlying causes, especially obstructions (including cerumen) and ototoxic medications. Residual hearing should be optimized by use of hearing aids, assistive listening devices, and rehabilitation programs. Surgical implants are indicated for selected patients. Major barriers to improved hearing in older adults include lack of recognition of hearing loss; perception that hearing loss is a normal part of aging or is not amenable to treatment; and patient nonadherence with hearing aids because of stigma, cost, inconvenience, disappointing initial results, or other factors.

  20. Tamm-Horsfall protein in recurrent calcium kidney stone formers with positive family history: abnormalities in urinary excretion, molecular structure and function.

    2007-04-01

    Tamm-Horsfall protein (THP) powerfully inhibits calcium oxalate crystal aggregation, but structurally abnormal THPs from recurrent calcium stone formers may promote crystal aggregation. Therefore, increased urinary excretion of abnormal THP might be of relevance in nephrolithiasis. We studied 44 recurrent idiopathic calcium stone formers with a positive family history of stone disease (RCSF(fam)) and 34 age- and sex-matched healthy controls (C). Twenty-four-hour urinary THP excretion was measured by enzyme linked immunosorbent assay. Structural properties of individually purified THPs were obtained from analysis of elution patterns from a Sepharose 4B column. Sialic acid (SA) contents of native whole 24-h urines, crude salt precipitates of native urines and individually purified THPs were measured. THP function was studied by measuring inhibition of CaOx crystal aggregation in vitro (pH 5.7, 200 mM sodium chloride). Twenty-four-hour urine excretion of THP was higher in RCSF(fam) (44.0 +/- 4.0 mg/day) than in C (30.9 +/- 2.2 mg/day, P = 0.015). Upon salt precipitation and lyophilization, elution from a Sepharose 4B column revealed one major peak (peak A, cross-reacting with polyclonal anti-THP antibody) and a second minor peak (peak B, not cross-reacting). THPs from RCSF(fam) eluted later than those from C (P = 0.021), and maximum width of THP peaks was higher in RCSF(fam )than in C (P = 0.024). SA content was higher in specimens from RCSF(fam) than from C, in native 24-h urines (207.5 +/- 20.4 mg vs. 135.2 +/- 16.1 mg, P = 0.013) as well as in crude salt precipitates of 24-h urines (10.4 +/- 0.5 mg vs. 7.4 +/- 0.9 mg, P = 0.002) and in purified THPs (75.3 +/- 9.3 microg/mg vs. 48.8 +/- 9.8 microg/mg THP, P = 0.043). Finally, inhibition of calcium oxalate monohydrate crystal aggregation by 40 mg/L of THP was lower in RCSF(fam) (6.1 +/- 5.5%, range -62.0 to +84.2%) than in C (24.9 +/- 6.0%, range -39.8 to +82.7%), P = 0.022, and only 25 out of 44 (57%) THPs from RCSF

    In respect of demographic change, the number of older patients with substance abuse and addiction is on the raise. In this review we present important clinical and therapeutic aspects of substance abuse and addiction in the elderly and focus on alcohol, benzodiazepines and opioids. Daily and risky alcohol consumption is common among older people. They also have an increased risk getting alcohol-related complications. For early detection, laboratory parameters and questionnaires such as the AUDIT-C are suitable. Therapeutically brief interventions have been proved successful. Also, abuse of benzodiazepines, especially low-dose addiction, is widespread among older persons, although often overlooked, and patients often do not recognize their addiction. The physician has to know the correct indication, adequate dosage and pharmacological interactions. A slow-dose reduction is recommended in case of addiction. Thanks to opioid substitution therapy, patients with an opioidaddiction can reach a higher age. Age influences the effects of the substitute, which may require an adjustment of the dosage. Treatment of elderly patients should be based on their needs and resources and is usually very effective.

    Eating disorders (EDs) are disturbances that seriously endanger the physical health and often the lives of sufferers and affect their psychosocial functioning. EDs are usually thought of as problems afflicting teenagers. However, the incidence in older women has increased in recent decades. These cases may represent either late-onset disease or, more likely, a continuation of a lifelong disorder. The DSM-5 classification differentiates 4 categories of eating disorder: anorexia nervosa, bulimia nervosa, binge-eating disorders and other specified feeding and eating disorders. The weight loss and malnutrition resulting from EDs have widespread negative consequences for physical, mental and social health. The main risk factors for developing long-term consequences are the degree of weight loss and the chronicity of the illness. Most of the cardiac, neurological, pulmonary, gastric, haematological and dermatological complications of EDs are reversible with weight restoration. EDs are serious illnesses and they should never be neglected or treated only as a manifestation of the fashion for dieting or a woman's wish to achieve an imposed standard feminine figure. Additionally, EDs are associated with high risk of morbidity and mortality. The literature concerning EDs in older, postmenopausal women is very limited. The main aim of this paper is to ascertain the epidemiology and prognosis of EDs in older women, and to review their diagnosis and management. PMID:26261037

  3. Dry mouth and older people.

    PubMed

    Thomson, W M

    2015-03-01

    Dry mouth is more common among older people than in any other age group. Appropriate definition and accurate measurement of dry mouth is critical for better understanding, monitoring and treatment of the condition. Xerostomia is the symptom(s) of dry mouth; it can be measured using methods ranging from single questions to multi-item summated rating scales. Low salivary flow (known as salivary gland hypofunction, or SGH) must be determined by measuring that flow. The relationship between SGH and xerostomia is not straightforward, but both conditions are common among older people, and they affect sufferers' day-to-day lives in important ways. The major risk factor for dry mouth is the taking of particular medications, and older people take more of those than any other age group, not only for symptomatic relief of various age-associated chronic diseases, but also in order to reduce the likelihood of complications which may arise from those conditions. The greater the number taken, the greater the associated anticholinergic burden, and the more likely it is that the individual will suffer from dry mouth. Since treating dry mouth is such a challenge for clinicians, there is a need for dentists, doctors and pharmacists to work together to prevent it occurring.

    Cochlear implants allow individuals with severe-to-profound hearing loss access to sound and spoken language. The number of older adults in the United States who are potential candidates for cochlear implantation is approximately 150,000 and will continue to increase with the aging of the population. Should cochlear implantation (CI) be routinely recommended for these older adults, and do these individuals benefit from CI? We reviewed our 12 year experience with cochlear implantation in adults ≥60 years (n = 445) at Johns Hopkins to investigate the impact of CI on speech understanding and to identify factors associated with speech performance. Complete data on speech outcomes at baseline and 1 year post-CI were available for 83 individuals. Our results demonstrate that cochlear implantation in adults ≥60 years consistently improved speech understanding scores with a mean increase of 60. 0% (S. D. 24. 1) on HINT sentences in quiet . The magnitude of the gain in speech scores was negatively associated with age at implantation such that for every increasing year of age at CI the gain in speech scores was 1. 3 percentage points less (95% CI: 0. 6 – 1. 9) after adjusting for age at hearing loss onset. Conversely, individuals with higher pre-CI speech scores (HINT scores between 40–60%) had significantly greater post-CI speech scores by a mean of 10. 0 percentage points (95% CI: 0. 4 – 19. 6) than those with lower pre-CI speech scores (HINT <40%) after adjusting for age at CI and age at hearing loss onset. These results suggest that older adult CI candidates who are younger at implantation and with higher preoperative speech scores obtain the highest speech understanding scores after cochlear implantation with possible implications for current Medicare policy. Finally, we provide an extended discussion of the epidemiology and impact of hearing loss in older adults. Future research of CI in older adults should expand beyond simple speech outcomes to take into

    Background Sensitive and specific detection of malarial parasites is crucial in controlling the significant malaria burden in the developing world. Also important is being able to identify life threatening Plasmodium falciparum malaria quickly and accurately to reduce malaria related mortality. Existing methods such as microscopy and rapid diagnostic tests (RDTs) have major shortcomings. Here, we describe a new real-time PCR-based diagnostic test device at point-of-care service for resource-limited settings. Methods Truenat® Malaria, a chip-based microPCR test, was developed by bigtec Labs, Bangalore, India, for differential identification of Plasmodium falciparum and Plasmodium vivax parasites. The Truenat Malaria tests runs on bigtec’s Truelab Uno® microPCR device, a handheld, battery operated, and easy-to-use real-time microPCR device. The performance of Truenat® Malaria was evaluated versus the WHO nested PCR protocol. The Truenat® Malaria was further evaluated in a triple-blinded study design using a sample panel of 281 specimens created from the clinical samples characterized by expert microscopy and a rapid diagnostic test kit by the National Institute of Malaria Research (NIMR). A comparative evaluation was done on the Truelab Uno® and a commercial real-time PCR system. Results The limit of detection of the Truenat Malaria assay was found to be <5 parasites/μl for both P. falciparum and P. vivax. The Truenat® Malaria test was found to have sensitivity and specificity of 100% each, compared to the WHO nested PCR protocol based on the evaluation of 100 samples. The sensitivity using expert microscopy as the reference standard was determined to be around 99.3% (95% CI: 95.5–99.9) at the species level. Mixed infections were identified more accurately by Truenat Malaria (32 samples identified as mixed) versus expert microscopy and RDTs which detected 4 and 5 mixed samples, respectively. Conclusion The Truenat® Malaria microPCR test is a valuable

    Makers, engineers and the applied physics community have adapted Arduino microcontrollers due to their versatility, robustness and cost effectiveness. Arduino microcontroller environment coupled with commercially available sensors have been used to systematically measure, record and analyze temperature, humidity and barometric pressure for building a simplified weather station for subsequent educational purposes. This data will become available in classroom settings for real-time analysis towards simple weather forecasting. Setup was assembled via breadboard, wire and simple soldering with an Arduino Uno ATmega328P microcontroller connected to a PC. The microcontroller was programmed with Arduino Software while the bootloader was used to upload the code. Commercial DHT22 humidity and temperature sensor, and BMP180 barometric pressure sensor were used to obtain relative humidity, temperature and the barometric pressure. A weather resistant enclosure protected the system while stable real-time data measurements were obtained, and uploaded onto the PC. The data was used to predict atmospheric conditions and lifting condensation level (LCL). Discussion will focus on capabilities and limitations of these systems and corresponding teaching aspects.

  8. Preserving mobility in older adults.

    PubMed Central

    Buchner, D M

    1997-01-01

    Age-related loss of strength contributes to impaired mobility and increases the risk of falls. Recent research has focused on 2 approaches to preventing age-related loss of strength--promoting physical activity and exercise (especially strength training) and using trophic factors to enhance muscle performance. Epidemiologic evidence strongly supports a role of regular physical activity in successful aging by preserving muscle performance, promoting mobility, and reducing fall risk. Randomized controlled trials provide convincing evidence that strength and endurance training improve muscle performance in older adults. Evidence is rapidly accumulating from randomized trials that endurance, strength, and balance training promote mobility and reduce fall risk, though exercise effects differ according to the type of exercise, details of the exercise program, and the target group of older adults. Because lifetime regular physical activity is recommended for all older adults, a reasonable strategy (especially for weak adults) is an activity program that includes strength training. In contrast, insufficient evidence exists to recommend the long-term use of trophic factors to preserve muscular performance. An intervention that merits additional study is avoiding the use of psychoactive drugs because drugs like benzodiazepines appear to be risk factors for inactivity and may have unrecognized direct effects on muscular performance. Because chronic illness is a risk factor for inactivity and disuse muscle atrophy, randomized trials comparing strength training with other interventions would be useful in understanding whether strength training has advantages in preserving muscle performance and improving health-related quality of life in a variety of chronic illnesses such as depressive illness.

    Sepsis is a potentially fatal response to infection affecting patients across the life span. Sepsis can progress from systemic inflammatory response to severe sepsis and septic shock if not recognized promptly and managed effectively. Risk factors for sepsis include age, gender, the presence of invasive devices (eg, urinary catheters), and chronic medical conditions (eg, chronic obstructive pulmonary disease). Sepsis awareness is essential and includes identification of population-focused risk factors, recognition of clinical signs and symptoms, and timely implementation of interventions. The purpose of this article was to examine sepsis in older adults, including prevalence, atypical presentation of the condition, and considerations for sepsis management in the elderly population.

  12. Sarcopenia, Frailty, and Diabetes in Older Adults

    PubMed Central

    2016-01-01

    Populations are aging and the prevalence of diabetes mellitus is increasing tremendously. The number of older people with diabetes is increasing unexpectedly. Aging and diabetes are both risk factors for functional disability. Thus, increasing numbers of frail or disabled older patients with diabetes will increase both direct and indirect health-related costs. Diabetes has been reported as an important risk factor of developing physical disability in older adults. Older people with diabetes have lower muscle mass and weaker muscle strength. In addition, muscle quality is poorer in diabetic patients. Sarcopenia and frailty have a common soil and may share a similar pathway for multiple pathologic processes in older people. Sarcopenia is thought to be an intermediate step in the development of frailty in patients with diabetes. Thus, early detection of sarcopenia and frailty in older adults with diabetes should be routine clinical practice to prevent frailty or to intervene earlier in frail patients. PMID:27098509

    This interpretive study explored older people's understanding of loneliness and what they considered appropriate and effective ways of dealing with it. Thirty elderly people were interviewed in-depth; 12 described themselves as “lonely” and 18 as “not lonely.” We found a striking difference in the way “lonely” and “not lonely” people talked about loneliness. The “not lonely” participants described loneliness as painful, caused by the person's negative way of behaving and a state they should pull themselves out of. The “lonely” participants also described loneliness as painful, and gave more detailed descriptions of loneliness as disconnection from others, from their former home and from today's society. The “lonely” participants were more reserved and subdued in trying to explain loneliness, attributing it partly to themselves, but mostly to the lack of social contact with important others. Some felt able to handle their loneliness, while others felt unable to cope. This study underlines the importance of subjective experiences in trying to understand a phenomenon like loneliness and of developing support for lonely older people unable to cope on their own.

    2016-04-15

    Although cancer is the second leading cause of death among persons 65 years and older, there is a paucity of clinical trial data about the effectiveness and harms of cancer screening in this population. Given the heterogeneous nature of the older population, cancer screening in these patients should not be based on age alone. Studies suggest that a life expectancy of at least 10 years is necessary to derive a survival benefit from screening for breast and colorectal cancers; therefore, screening for these cancers is not recommended in those with a life expectancy of less than 10 years. Prostate cancer screening, if performed at all, should not be performed after 69 years of age. Cervical cancer screening may be stopped after 65 years of age if the patient has an adequate history of negative screening results. An individualized approach to cancer screening decisions involves estimating life expectancy, determining the potential benefits and harms of screenings, and weighing those benefits and harms in relation to the patient's values and preferences.

Concerning bone health, it seems that physical activity in the past can be protective against osteoporosis in postmenopausal women, but these data come from observational studies only. Also the cardiovascular system appears to benefit in older women from regular sport in the past. This refers mainly to better heart efficiency, and improved endothelial function and metabolic profile. The incidence of different types of neoplasms, especially breast cancer, is also decreased in former athletes. Professional sport, on the other hand, acts negatively on the pelvic floor and is a risk factor for urinary incontinence. The overall effect on mortality is difficult to assess, because of many parameters, such as the sport's intensity, variety of the sport and exposure to extreme danger in some disciplines. Also, caution should be kept in interpretation of the data because of the shortage of well-designed studies.

    The recently developed Everyday Cognition scales (ECog) measure multiple cognitively-relevant functional domains (e.g. Everyday Memory, Everyday Language, Everyday Visuospatial abilities and three everyday executive domains). The present study further evaluated the validity of the ECog by examining its relationship with objective measures of neuropsychological function, and neurobiological markers of disease as reflected by structural neuroimaging. Participants included 474 older adults (244 normals, 142 with MCI, 88 with dementia). The neuropsychological domains measured were episodic memory, semantic memory, spatial ability, and executive functioning. Brain MRI volumes included total brain (BV), hippocampus (HC) and dorsolateral prefrontal cortex (DLPFC). Neuropsychological measures of episodic memory and executive function were most consistently related to the ECog domains; spatial abilities had a specific relationship to the Everyday Visuospatial ECog domain. HC and BV volumes were related to most ECog domains, while DLPFC volume was independently related to two everyday executive domains (Everyday Planning and Everyday Organization). The pattern of associations varied somewhat as a function of diagnosis. Episodic memory and HC had more consistent associations with the ECog domains in older adults with MCI/dementia than in cognitively normal elderly. PMID:23369894

  17. Valence excitation energies of alkenes, carbonyl compounds, and azabenzenes by time-dependent density functional theory: Linear response of the ground state compared to collinear and noncollinear spin-flip TDDFT with the Tamm-Dancoff approximation

    Time-dependent density functional theory (TDDFT) holds great promise for studying photochemistry because of its affordable cost for large systems and for repeated calculations as required for direct dynamics. The chief obstacle is uncertain accuracy. There have been many validation studies, but there are also many formulations, and there have been few studies where several formulations were applied systematically to the same problems. Another issue, when TDDFT is applied with only a single exchange-correlation functional, is that errors in the functional may mask successes or failures of the formulation. Here, to try to sort out some of the issues, we apply eight formulations of adiabatic TDDFT to the first valence excitations of ten molecules with 18 density functionals of diverse types. The formulations examined are linear response from the ground state (LR-TDDFT), linear response from the ground state with the Tamm-Dancoff approximation (TDDFT-TDA), the original collinear spin-flip approximation with the Tamm-Dancoff (TD) approximation (SF1-TDDFT-TDA), the original noncollinear spin-flip approximation with the TDA approximation (SF1-NC-TDDFT-TDA), combined self-consistent-field (SCF) and collinear spin-flip calculations in the original spin-projected form (SF2-TDDFT-TDA) or non-spin-projected (NSF2-TDDFT-TDA), and combined SCF and noncollinear spin-flip calculations (SF2-NC-TDDFT-TDA and NSF2-NC-TDDFT-TDA). Comparing LR-TDDFT to TDDFT-TDA, we observed that the excitation energy is raised by the TDA; this brings the excitation energies underestimated by full linear response closer to experiment, but sometimes it makes the results worse. For ethylene and butadiene, the excitation energies are underestimated by LR-TDDFT, and the error becomes smaller making the TDA. Neither SF1-TDDFT-TDA nor SF2-TDDFT-TDA provides a lower mean unsigned error than LR-TDDFT or TDDFT-TDA. The comparison between collinear and noncollinear kernels shows that the noncollinear kernel

  19. Smiling makes you look older.

    PubMed

    Ganel, Tzvi

    2015-12-01

    People smile in social interactions to convey different types of nonverbal communication. However, smiling can potentially change the way a person is perceived along different facial dimensions, including perceived age. It is commonly assumed that smiling faces are perceived as younger than faces carrying a neutral expression. In the series of experiments reported here, I describe an unintuitive and robust effect in the opposite direction. Across different experimental conditions and stimulus sets, smiling faces were consistently perceived as older compared to neutral face photos of the same persons. I suggest that this effect is due to observer failure to ignore smile-associated wrinkles, mainly along the region of the eyes. These findings point to a misconception regarding the relationship between facial smile and perceived age and shed new light on the processes underlying human age perception.

  20. Flashbulb memories in older adults.

    PubMed

    Cohen, G; Conway, M A; Maylor, E A

    1994-09-01

    In this study of age differences in flashbulb memory, groups of young and older adults gave detailed accounts of how they heard the news of the resignation of the British Prime Minister Margaret Thatcher. They were tested within 14 days after the event and again 11 months later. They also gave ratings for the encoding variables (surprise, emotion, importance, knowledge, and interest) and for frequency of rehearsal. Memories that met a strict criterion of consistency between the original and delayed responses were classified as flashbulb memories. Although 90% of young Ss had flashbulb memories, only 42% of the elderly met the criterion. The age groups also differed in the type of details remembered and in the relationship between the encoding and rehearsal variables and the occurrence of flashbulb memory. The age-related deficit in flashbulb memory is related to source amnesia and to a deficit in memory for context.

    2013-10-01

    World Health Organization(WHO) proposed to be used as an index of the health of elderly independence of functioning. Basic activities of daily living (BADL), such as bathing, dressing, toileting, transferring, continence, and feeding are well known as the functioning of the elderly. However, not only BADL, there are a variety of levels, such as the ability to play a social role, intellectual activities and instrumental activities of daily living (IADL), which are components of the Tokyo Metropolitan Institute of Gerontology Index of Competence(TMIG-IC). Functional decline in older people is associated with age, gender, depression, up and go test and manual dexterity. Smoking, body-mass index, and exercise patterns in midlife and late adulthood are predictors of subsequent disability. PMID:24261199

    As American lifespans increase, there is greater concern for the quality of those longer lives. The Department of Health and Human Services, through its many component agencies, has inaugurated a major initiative to promote health and fitness among older Americans to improve life quality and to reduce health care costs. The older population is a fertile ground for such an initiative, because studies indicate that the elderly are extremely health-conscious and very willing to adopt habits that will maintain good health. Investigation disclosed six target areas of concentration at which the health promotion initiative could be aimed: fitness-exercise, nutrition, safe and proper use of drugs and alcohol, accident prevention, other preventive services, and smoking cessation. The initiative includes cooperative programs with States; dissemination of printed information; nutritious meals for the elderly; a Food and Drug Administration consumer education program; Centers for Disease Control programs on accident prevention; a special task force to deal with Alzheimer's disease; and, in cooperation with states, a media campaign of health promotion for the elderly. At least three national health and senior citizens organizations are working closely with HHS agencies on the initiative. A separate Department effort involves the encouragement of fast-growing health maintenance organizations to promote health and prevention for their Medicare members and the persuasion of Medicare beneficiaries generally to seek second medical or surgical opinions. State and local government and the private sector, responding to Department initiatives, have also been developing programs for the aging. Their interest and participation ensures that special health promotion and disease prevention efforts directed toward elderly Americans will continue and proliferate.

    PubMed

    Planton, Jonathan; Meyer, Jennifer O; Edlund, Barbara J

    2012-07-01

    A goal of primary prevention is to avoid the development of disease. Immunizations are one of several strategies used by clinicians in primary prevention. Influenza and pneumococcal disease--both preventable--cause significant morbidity and mortality in older adults who have an altered immune system, often have several chronic health problems, and are at higher risk for complications. Tetanus, while not as common in older adults, carries a high mortality rate in those 65 and older. These infections are associated with significant disability that results from hospitalizations for congestive heart failure, hip fracture, stroke, and pneumonia. The goal of immunizing older adults is to decrease functional decline and disability, as well as potential hospital admissions linked to these preventable diseases, which often exacerbate underlying health problems. Age-defined recommendations are available to guide clinicians on the appropriate vaccinations and schedules for administration to older adults. PMID:22715960

    2010-09-01

    Preparing for the future housing needs of older adults is imperative in countries with an aging population, but little is known about these issues among vulnerable older adults. This study used a qualitative approach to identify key housing concerns in this group. A total of 84 vulnerable older adults including Aboriginal elders, those with various disabilities, and ethnic minorities participated in 10 focus groups. The Canadian Mortgage and Housing Corporation's (CMHC's) standards of core housing need provided a framework for data analysis, along with the identification of additional key housing themes across and within groups of vulnerable older adults. The results provide insight into preferred housing characteristics, regardless of housing form. Additionally, the results provide insight into how to support vulnerable older adults who choose to remain in their homes and communities and how to help ensure that appropriate housing is developed that meets the needs of this diverse population.

    2016-09-01

    γ-ray transitions from excited states of {}16{{N}} and {}16{{O}} isomers that appear in the γ spectrum of the {}616{{{C}}}10\\to {}716{{{N}}}9\\to {}816{{{O}}}8 beta decay chain are investigated. The theoretical approach used in this research starts with a mean-field potential consisting of a phenomenological Woods-Saxon potential including spin-orbit and Coulomb terms (for protons) in order to obtain single-particle energies and wave functions for nucleons in a nucleus. A schematic residual surface delta interaction is then employed on the top of the mean field and is treated within the proton-neutron Tamm-Dancoff approximation (pnTDA) and the proton-neutron random phase approximation. The goal is to use an optimized surface delta interaction interaction, as a residual interaction, to improve the results. We have used artificial intelligence algorithms to establish a good agreement between theoretical and experimental energy spectra. The final results of the ‘optimized’ calculations are reasonable via this approach.

  15. The effect of basis set and exchange-correlation functional on time-dependent density functional theory calculations within the Tamm-Dancoff approximation of the x-ray emission spectroscopy of transition metal complexes.

    PubMed

    Roper, Ian P E; Besley, Nicholas A

    2016-03-21

    The simulation of X-ray emission spectra of transition metal complexes with time-dependent density functional theory (TDDFT) is investigated. X-ray emission spectra can be computed within TDDFT in conjunction with the Tamm-Dancoff approximation by using a reference determinant with a vacancy in the relevant core orbital, and these calculations can be performed using the frozen orbital approximation or with the relaxation of the orbitals of the intermediate core-ionised state included. Both standard exchange-correlation functionals and functionals specifically designed for X-ray emission spectroscopy are studied, and it is shown that the computed spectral band profiles are sensitive to the exchange-correlation functional used. The computed intensities of the spectral bands can be rationalised by considering the metal p orbital character of the valence molecular orbitals. To compute X-ray emission spectra with the correct energy scale allowing a direct comparison with experiment requires the relaxation of the core-ionised state to be included and the use of specifically designed functionals with increased amounts of Hartree-Fock exchange in conjunction with high quality basis sets. A range-corrected functional with increased Hartree-Fock exchange in the short range provides transition energies close to experiment and spectral band profiles that have a similar accuracy to those from standard functionals.

  16. Circadian temperature rhythms of older people

    Monk, T. H.; Buysse, D. J.; Reynolds, C. F. 3rd; Kupfer, D. J.; Houck, P. R.

    1995-01-01

    This collection of studies had the aim of exploring whether older (77+ years) men and women have circadian body temperature rhythms different from those of younger adults. A total of 20 older men and 28 older women were compared with either 22 young men or 14 middle-aged men in four protocols; all but the first protocol using a subset of the sample. The four protocols were: 1) 24 h, and 2) 72 h data collections on a normal laboratory routine (sleeping at night); 3) between 36 h and 153 h of field data collection at home; and 4) 36 h of a constant conditions routine (wakeful bedrest under temporal isolation) in the laboratory. There was some evidence for an age-related phase advance in temperature rhythm, especially for the older men on a normal routine, though this was not present in the constant conditions protocol, where 5 of the older subjects showed major delays in the timing of the body temperature trough (10:00 or later). There was no statistically significant evidence from any of the protocols that older subjects generally had lower temperature rhythm amplitudes than younger adults. Only when older men were compared with younger men in 24-h rhythm amplitude by simple t-test did any comparison involving amplitude achieve statistical significance (p < 0.05).

  17. Oxytocin improves emotion recognition for older males.

    2014-10-01

    Older adults (≥60 years) perform worse than young adults (18-30 years) when recognizing facial expressions of emotion. The hypothesized cause of these changes might be declines in neurotransmitters that could affect information processing within the brain. In the present study, we examined the neuropeptide oxytocin that functions to increase neurotransmission. Research suggests that oxytocin benefits the emotion recognition of less socially able individuals. Men tend to have lower levels of oxytocin and older men tend to have worse emotion recognition than older women; therefore, there is reason to think that older men will be particularly likely to benefit from oxytocin. We examined this idea using a double-blind design, testing 68 older and 68 young adults randomly allocated to receive oxytocin nasal spray (20 international units) or placebo. Forty-five minutes afterward they completed an emotion recognition task assessing labeling accuracy for angry, disgusted, fearful, happy, neutral, and sad faces. Older males receiving oxytocin showed improved emotion recognition relative to those taking placebo. No differences were found for older females or young adults. We hypothesize that oxytocin facilitates emotion recognition by improving neurotransmission in the group with the worst emotion recognition.

  18. Diagnostic challenges in the older patient

    2012-01-01

    Older patients often present with a long, complex history and a clinical picture that frequently includes co-morbidities. It is essential that health professionals caring for older patients become familiar with common age-related changes, and the specific clinical factors that complicate the diagnostic process. A case-based approach is taken in this article to explore the diagnostic challenges in caring for older patients. Three areas of focus are used: a) polypharmacy, b) cognitive issues such as delirium, dementia and depression, and c) increased odds of pathologies and chronic illnesses. PMID:22950718

    2009-01-01

    We used 1997–2004 National Health Interview Survey data to evaluate the prevalence of sensory impairment among US workers 65 years and older. Hearing impairment prevalence was 3 times that of visual impairment (33.4% vs 10.2%), and 38% of older workers reported experiencing either impairment. Farm operators, mechanics, and motor vehicle operators had the highest prevalence of sensory impairment. Workplace screening and accommodations, including sensory protection devices for older workers, are warranted given the greater risk for injuries among the sensory impaired. PMID:19542042

  20. Employment Hardship Among Older Workers: Does Residential and Gender Inequality Extend Into Older Age?

    Objectives. The realities of a rapidly aging society make the employment circumstances of older workers an increasingly important social issue. We examine the prevalence and correlates of underemployment among older Americans, with a special focus on residence and gender, to provide an assessment of the labor market challenges facing older workers. Methods. We analyzed data from the March Current Population Surveys for the years 2003, 2004, and 2005. We used descriptive statistics to explore the prevalence of underemployment among older workers and developed multivariate models to assess the impact of age, residence, and gender on the likelihood of underemployment, net of other predictors. Results. We found clear disadvantages for older workers relative to their middle-aged counterparts, and particular disadvantages for older rural residents and women. Multivariate models showed that the disadvantages of older age held net of other predictors. The results also indicated that much of the disadvantage faced by older rural workers and women was explained by factors other than age, particularly education. Discussion. In an aging society, underemployment among older workers comes at an increasing social cost. Policies aimed at supporting older workers and alleviating employment hardship among them are increasingly in the public interest. PMID:18332197

  9. Is cancer vaccination feasible at older age?

    PubMed Central

    Gravekamp, Claudia; Jahangir, Arthee

    2014-01-01

    Age-related defects of the immune system are responsible for T cell unresponsiveness to cancer vaccination at older age. Major immune defects at older age are lack of naïve T cells, impaired activation pathways of T cells and antigen-presenting cells (APC), and age-related changes in the tumor microenvironment (TME). This raises the question whether cancer vaccination is feasible at older age. We compared various cancer vaccine studies at young and old age, thereby focusing on the importance of both innate and adaptive immune responses for cancer immunotherapy. These analyses suggest that creating an immune-stimulating environment with help of the innate immune system may improve T cell responses in cancer vaccination at older age. PMID:24509231

  11. Dietary factors and depression in older people.

    PubMed

    Williamson, Claire

    2009-10-01

    Depression is one of the most prevalent mental health conditions and can affect people of all ages, but it is becoming more common among the older population with increasing life expectancy. Observational studies have found poor micronutrient status (particularly folate and vitamin B12) to be associated with an increased risk of depression in older people. Supplementation with folic acid has been shown to enhance anti-depressant drug treatment and there is preliminary evidence that supplementation with certain micronutrients may help improve depressive symptoms in older patients. There has also been a lot of interest in the role of long-chain omega-3 fatty acids in depression. However, the evidence from randomized controlled trials is limited and difficult to evaluate owing to considerable variability between studies. The research highlights the importance of a healthy diet and lifestyle to help maintain good mental health into old age and health professionals should try to support older people in trying to achieve this.

  12. Not yet equal: employment experience of older women and older men.

    PubMed

    Kahne, H

    Women age forty-five and over are an important component of all working women and of the older labor force. They make up almost 30 percent of the female civilian labor force. Of the older labor force, 40 percent are women. Yet contrary to societal values about equality in the market place, employment-related experience of older women is not only different from that of men but frequently disadvantaged. This article examines the growing importance of the issue of market equality of older working women. It then considers six ways in which their employment-related experience differs from that of men: labor force participation rates; occupational distribution; earnings; unemployment; poverty; and retirement income. The article concludes with suggested policy directions that would improve the status of older women. Some of these would assist, as well, employment needs of older men.

    We examined older and younger adults’ accuracy judging the health and competence of faces. Accuracy differed significantly from chance and varied with face age but not rater age. Health ratings were more accurate for older than younger faces, with the reverse for competence ratings. Accuracy was greater for low attractive younger faces, but not for low attractive older faces. Greater accuracy judging older faces’ health was paralleled by greater validity of attractiveness and looking older as predictors of their health. Greater accuracy judging younger faces’ competence was paralleled by greater validity of attractiveness and a positive expression as predictors of their competence. Although the ability to recognize variations in health and cognitive ability is preserved in older adulthood, the effects of face age on accuracy and the different effects of attractiveness across face age may alter social interactions across the life span.

    2016-03-01

    Employing a participatory arts-based research approach, we examined an innovative program from rural Ontario, Canada, designed to address social isolation among older people. Older socially isolated adults were matched to trained volunteers, where in dyads, the eight pairs created expressive art in their home setting over the course of 10 home visits. With thematic and narrative inquiry, we analysed the experiences and perceptions of the program leader, older participants, and older volunteers via their artistic creations, weekly logs, evaluations, and field notes. The findings reveal a successful intervention that positively influenced the well-being of older adult participants and older volunteers, especially in regards to relationships, personal development, and creating meaning as well as extending the intervention's impact beyond the program's duration. We also discuss opportunities for similar programs to inform policy and enable positive community-based health and social service responses to rural social isolation. PMID:26934547

    Nutrition in older adults on peritoneal dialysis is an important aspect of a patient's clinical management as well as being influenced by their overall well-being, both mental and physical. This is especially pertinent as individuals age, since the potential impact of life changes and physical changes contribute to the development of protein-energy wasting and potentially exacerbating sarcopenia and wasting. This article provides an outline of the nutritional issues to consider in older adults on peritoneal dialysis (PD).

    A need for dental implant treatment in the older population is recognized considering the prevalence of partial and complete edentulism and the positive predictability of implant therapy. Even with a number of barriers to overcome for the older adult seeking implant care, dental implants provide stabilizing support for removable dental appliances and have been shown to be successful in that population. In this paper, we describe quality of life, systemic, surgical, and prosthodontic considerations of this prosthetic treatment along with maintenance challenges.

    2016-04-01

    This study concentrates on the cycling strategies of older cyclists (54-62year olds) in comparison to young cyclists (20-30year olds). While cycling in a safe laboratory set-up, controlled lateral perturbations are applied to the rear of the bicycle. Three possible strategies to keep balance are analysed for a young and older aged group: steering, lateral trunk movement and outward knee movement. Older subjects appear to rely more on knee movement as a control mechanism than young subjects. Furthermore, the frequency domain analysis revealed that the older adults need more effort to counteract high frequency perturbations. Increased inter-individual variation for the older adults subject group suggests that this group can be seen as a transition group in terms of physical fitness. This explains their increased risk in single-sided bicycle accidents (i.e. accidents involving the cyclist only). Therefore, older cyclists could benefit from improving the stability of cycling at lower speeds. PMID:26796419

    2014-01-01

    We aimed at reviewing age-related changes in kidney structure and function, methods for estimating kidney function, and impact of reduced kidney function on geriatric outcomes, as well as the reliability and applicability of equations for estimating glomerular filtration rate (eGFR) in older patients. CKD is associated with different comorbidities and adverse outcomes such as disability and premature death in older populations. Creatinine clearance and other methods for estimating kidney function are not easy to apply in older subjects. Thus, an accurate and reliable method for calculating eGFR would be highly desirable for early detection and management of CKD in this vulnerable population. Equations based on serum creatinine, age, race, and gender have been widely used. However, these equations have their own limitations, and no equation seems better than the other ones in older people. New equations specifically developed for use in older populations, especially those based on serum cystatin C, hold promises. However, further studies are needed to definitely accept them as the reference method to estimate kidney function in older patients in the clinical setting. PMID:24772439

    2008-08-01

    A survey was conducted with 262 commencing nursing students at a South Australian university, during a compulsory orientation week lecture prior to the first week of their nursing degree, to determine their attitudes towards older people and to working with older people. The survey provides baseline data to evaluate the efficacy of the Partnerships in Aged Care (PACE) Action Research project, the focus of which is developing aged care curriculum and placements with aged care industry partners. The survey will be replicated when this cohort completes their nursing degree. The results of this initial survey show that while commencing students generally have positive attitudes towards older people they do not aspire to work with them. The reasons cited for a lack of interest in working with older people include: poor experiences of providing care for older people; an inability to relate to or communicate with older people and a perception that the work is depressing and boring. Underpinning a negative perception of working with older people is the association of ageing with disability. Ageing for this cohort, is associated with loss of mental and physical function; loss of independence and increasing reliance on others to meet self care needs. This is viewed as evidence of a biomedical view of ageing. Contrary to previous research, many students studied in this project, who have had experience of working with older people, demonstrate more positive attitudes to older people and are less likely to express stereotypical attitudes towards ageing suggesting that positive exposure to older people can challenge ageist views. The PACE project seeks to demonstrate that strategies which may promote a positive attitude to ageing such as development of educational content which promotes a quality of life rather than a biomedical approach to ageing and supported clinical placements can impact positively on nursing students perception of ageing and of working with older people.

  5. Exercise physiology of the older horse.

    PubMed

    McKeever, Kenneth Harrington

    2002-12-01

    Surveys indicate that up to 15% of the equine population in the United States is older than 20 years of age, with many of these animals performing various athletic activities well into their 20s. As is the case with their human counterparts, these geriatric equine athletes have the ability to continue to perform in athletic events. Unfortunately, many horse owners continue to train their active older animals using exercise training protocols that, although appropriate for a younger animal, may not be appropriate for the older equine athlete. Studies in aged human beings have led to a fine-tuning of exercise prescription for the older human athlete so as to prevent the adverse and potentially dangerous effects of excessive work. Published results have led to new and improved programs to promote fitness for the growing population of older adults. Unfortunately, limited data exist regarding the exercise capacity of the aged horse. Future studies on the effects of aging on exercise capacity in equine athletes need to take a few major directions. One question to be answered is at what age does physiologic function first begin to decline in the horse? In human beings, this age varies with training, but noticeable changes in aerobic capacity are first seen in 40- to 50-year-olds. Second, data are needed to determine what levels of exercise enhance the health and well-being of the older horse without harm. Lastly, studies are needed to determine the physiologic mechanisms associated with the onset of aging-induced decreases in physiologic function in the horse. The ultimate goal of all these studies should be to adjust exercise levels to meet the needs of the growing population of athletically active older equine athletes.

    The current study examined electrophysiological entropy in younger adults, older adults, and older cognitively declined adults across four experimental conditions - eyes closed, eyes open, and during both encoding and recognition of words in a memory task. We hypothesised reduced entropy in older declined adults relative to both older controls and younger adults, with the largest group differences in entropy expected during the encoding and recognition phases of the experiment. We also hypothesised greater hemispheric asymmetry in younger adults compared with older controls and older declined adults. Results revealed significant increases in entropy from eyes closed to eyes open to task. Young adults showed higher entropy in the right relative to the left hemisphere in the temporal lobe and higher entropy in the left relative to the right hemisphere in the parietal lobe. Old cognitively declined adults showed no significant differences between right and left hemisphere entropy. There was a trend whereby older declined adults showed lower entropy than older controls in the frontal lobe, this difference being largest in the left hemisphere during the encoding phase of the experiment. Results indicate that measures of entropy are sensitive to information processing demands and that higher cognitive performance may not be a simple function of entropy level, but rather a combination of level and range, or differentiated range of entropy states across the brain.

    Page, Phil; Takeshima, Nobuo

    2013-01-01

    As the older adult population increases in size, the number of older adults participating in sport activities will also likely increase proportionally with a concomitant increase in musculoskeletal injuries. Age-associated functional declines in muscle strength and the sensory systems, in addition to several other issues, contribute to reductions in balance that may increase fall risk There are a variety of ways to evaluate balance and fall-risk, and each older adult should be regularly screened in order to evaluate any changes in the ability to maintain postural stability. Balance training is a useful intervention in rehabilitation of postural stability impairments as well as in training programs for performance enhancement. One scientifically-based approach is Sensorimotor Training (SMT) which can be characterized as a progressive balance training program using labile surfaces to provide adequate and safe challenges to the older athlete's balance. SMT addresses both static and dynamic components of balance as well as the multitude of systems that control balance in order to train effective strategies and elicit automatic postural responses in order to enhance postural stability. The authors believe that SMT should become part of the regular training regimen for the aging athlete. For the sport and orthopedic healthcare professional, an understanding of the physiologic changes that occur with age, the means by which balance can be assessed, and how SMT programs can be developed and implemented is crucial in addressing the growing number of older athletes that they will see.

    A focus on the right to the enjoyment of the highest attainable standard of health (hereinafter, "the right to health") draws attention to the health needs of older people, including the most marginalized among them. Many factors that influence vulnerability or impede the enjoyment of health and access to quality services result from an inability to freely exercise these human rights. A human rights approach can help to address the legal, social, and structural barriers to good health for older persons, clarifying the legal obligations of State and non-State actors to uphold and respect these rights. However, despite growing impetus for action, this area has historically received limited attention. Drawing on practice examples from different regions, this article unpacks the meaning of the right to health and other related human rights of older people in practice, covering both health care and underlying determinants of their health. Questions of availability, accessibility, acceptability, and quality are highlighted from the perspective of older people's health and well-being. The article brings together knowledge, principles, norms, and standards from the human rights law, health, and ageing arenas. By making links between these arenas, it is hoped that the article fills a gap in thinking on how to achieve the progressive realization of the right to health of older people and the effective promotion and protection of their other related human rights, which are crucial for the enjoyment of health.

    2015-01-01

    Bilateral leg edema is a frequent symptom in older people and an important concern in geriatric medicine. Further evaluation is frequently not performed and simple therapy with diuretics is prescribed. Particularly in older patients, long-term use of diuretics can lead to severe electrolyte imbalances, volume depletion, and falls. In this case report we want to focus the physicians' attention on the necessity to determine the cause and show a correspondingly effective treatment for bilateral leg edema in older people. A thorough approach is required to recognize diseases and to avoid adverse drug events as geriatric patients often show an atypical presentation or minor symptoms. The cause of swollen legs is often multifactorial; therefore, the patient's individual history and an appropriate physical examination are important. Depending on the clinical symptoms, evaluation including basic laboratory tests, urinalysis, chest radiography, and echocardiogram may be indicated. The most probable cause of bilateral edema in older patients is chronic venous insufficiency. Heart failure is also a common cause. Other systemic causes such as renal disease or liver disease are much rarer. Antihypertensive and anti-inflammatory drugs can frequently cause leg edema, but the incidence of drug-induced leg swelling is unknown. With the help of this special case we tried to develop an approach to the diagnosis of symmetric leg edema in older patients, a problem frequently neglected in geriatric medicine.

    Although physical activity is a recognized component in the management of many chronic diseases associated with aging, activity levels tend to progressively decline with increasing age (Manini & Pahor, 2009; Schutzer & Graves, 2004). In this article we examine the key factors that facilitate physical activity in highly active community-dwelling older adults. Using a strengths based approach, we examined the factors that facilitated physical activity in our sample of highly active older adults. Twenty-seven older adults participated in face-to face interviews. We extracted a sub-sample of 10 highly active older adults to be included in the analyses. Based on a framework analysis of our transcripts we identified three factors that facilitate physical activity in our sample, these include: 1) resourcefulness: engagement in self-help strategies such as self-efficacy, self-control and adaptability; 2) social connections: the presence of relationships (friend, neighborhood, institutions) and social activities that support or facilitate high levels of physical activity; and 3) the role of the built and natural environments: features of places and spaces that support and facilitate high levels of physical activity. Findings provide insight into, and factors that facilitate older adults' physical activity. We discuss implications for programs (e.g., accessible community centers, with appropriate programming throughout the lifecourse) and policies geared towards the promotion of physical activity (e.g., the development of spaces that facilitate both physical and social activities).

  17. Ovarian cancer in the older woman.

    Tew, William P

    2016-09-01

    Ovarian cancer is the seventh most common cancer in women worldwide and accounts for nearly 4% of all new cases of cancer in women. Almost half of all patients with ovarian cancer are over the age of 65 at diagnosis, and over 70% of deaths from ovarian cancer occur in this same age group. As the population ages, the number of older women with ovarian cancer is increasing. Compared to younger women, older women with ovarian cancer receive less surgery and chemotherapy, develop worse toxicity, and have poorer outcomes. They are also significantly under-represented in clinical trials and thus application of standard treatment regimens can be challenging. Performance status alone has been shown to be an inadequate tool to predict toxicity of older patients from chemotherapy. Use of formal geriatric assessment tools is a promising direction for stratifying older patients on trials. Elderly-specific trials, adjustments to the eligibility criteria, modified treatment regimens, and interventions to decrease morbidities in the vulnerable older population should be encouraged.

  18. Attitudes toward older people and coworkers' intention to work with older employees: a Taiwanese study.

    The aim of this research was to examine attitudinal barriers to the employment of Taiwanese older workers (aged 60 and above). Face-to-face interviews were conducted to collect data using structured questionnaires from a sample of full-time employees (N= 258). We found that: (1) positive attitudes toward older people in general, perceived subjective norm, and traditional Chinese cultural values were all related to stronger intentions to work with older employees; (2) the model derived from the theory of reasoned action emerged the best model accounting for behavioral intention among competing structural models. The associations of positive attitudes and subjective norm with intention were found after controlling for demographics, cultural values, and personal contact experiences with older people. Our results highlight the importance and urgency of more concerted research to inform public and organizational policies to better promote and manage the careers of older employees in an aging, economically developing society.

    In this study we will analyze the attitude of older adults to advertisements, differentiating between advertisements that contain rhetorical figures (trope ads) and those that do not (explicit ads). We will also study their attitude toward the brand advertised according to their degree of involvement with the product. In the course of the empirical research, a total of 183 personal surveys were carried out with people aged over 65 taking as reference 2 products with different prices and durabilities. Analysis of the results indicated that in products involving little economic effort, older adults showed the same attitude toward both trope and explicit advertisements. However, with products requiring greater economic effort, older adults showed differences in their attitudes to trope ads and to explicit ads depending on their degree of involvement with the product. These differences had a strong effect on their attitudes to the brands of the products analyzed.

    Elderly persons represent a growing percentage of the total population, and this tendency will become stronger in the coming years. To date, the little evidence available on primary and secondary prevention indicates that this population has high cholesterol levels, that few are under treatment, and that the degree of control requires improvement. Current guidelines recommend that treatment targets in older persons should be the same as those in younger patients. Nevertheless, it is important to remember certain characteristics in older persons, such as biological and metabolic changes or the higher incidence of atherogenic dyslipidemia, which will affect them. Moreover, quality of life and maintaining independence rather than mere survival are especially important in older individuals, as demonstrated by various surveys. Consequently, pravastatin -the most widely studied statin- seems to be the statin of choice for the control of triglycerides and residual risk, although fenofibrate is also useful.

  3. Depression and religiosity in older age.

    2011-09-12

    We investigated the hypothesis that religious commitment could help counter general affective distress, accompanying depressive symptoms, in older age. A total of 34 older adults, all catholic believers, completed self-reported questionnaires on the presence of depressive symptoms, religiosity, health, worry, and the style of coping with stress. The depressive and non-depressive subgroups were then created. The prevalence of depressive symptoms was 50%, with the substantial predominance of females. Regression analyses indicate that health expectations and worry significantly worsen with increasing intensity of depressive symptoms. The results further show that religious engagement was not different between the depressive and non-depressive subgroups. Religiosity failed to influence the intensity of depressive symptoms or the strategy of coping with stress in either subgroup, although a trend was noted for better health expectations with increasing religious engagement in depressive subjects. We conclude that religiosity is unlikely to significantly ameliorate dysphoric distress accompanying older age.

    Using the 2000/2001 Canadian Community Health Survey (CCHS), this paper examines the health status of the older (aged immigrant population relative to that of non-immigrants in order to identify areas where their health statuses diverge. First, we compare the health status of older immigrants (foreign-born) aged 55 and over in Canada to the Canadian-born in terms of age and gender using multiple measures of health status including self-assessed health. Second, we identify the factors associated with health status using the determinants of health framework. In both cases, the key questions are whether differences in health status exist and whether they are explained primarily by socio-economic, socio-demographic, or lifestyle factors that may point to problems with the Canadian health care system. Findings indicate that there is a relative comparability in the health status of older immigrants, even after controlling for age.

    Longevity is increasing and the population of older adults is growing. The biology of aging is conducive to cardiovascular disease (CVD), such that prevalence of coronary artery disease, heart failure, valvular heart disease, arrhythmia and other disorders are increasing as more adults survive into old age.  Furthermore, CVD in older adults is distinctive, with management issues predictably complicated by multimorbidity, polypharmacy, frailty and other complexities of care that increase management risks (e.g., bleeding, falls, and rehospitalization) and uncertainty of outcomes.  In this review, state-of-the-art advances in heart failure, acute coronary syndromes, transcatheter aortic valve replacement, atrial fibrillation, amyloidosis, and CVD prevention are discussed.  Conceptual benefits of treatments are considered in relation to the challenges and ambiguities inherent in their application to older patients.

    Abstract The success of home telemedicine depends on end-user adoption, which has been slow despite rapid advances in technological development. This study focuses on an examination of significant factors that may predict the successful adoption of home telemedicine services (HTS) among older adults. Based on previous studies in the fields of remote patient monitoring, assisted living technologies, and consumer health information technology acceptance, eight factors were identified as a framework for qualitative testing. Twelve focus groups were conducted with an older population living in both urban and rural environments. The results reveal seven predictors that play an important role in perceptions of HTS: perceived usefulness, effort expectancy, social influence, perceived security, computer anxiety, facilitating conditions, and physicians' opinion. The results provide important insights in the field of older adults' acceptance of HTS, with guidelines for the strategic planning, developing, and marketing of HTS for the graying market.

    The purpose of this literature review was to provide an overview of resilience for the purpose of informing potential intervention designs that may benefit older adults. While numerous reviews have focused on various specific aspects of resilience, none have provided the necessary information required to design an effective resilience intervention. Research examining resilience suggests that older adults are capable of high resilience despite socioeconomic backgrounds, personal experiences, and declining health. Thus opportunities to inform interventions in this area exist. Research studies have identified the common mental, social, and physical characteristics associated with resilience. High resilience has also been significantly associated with positive outcomes, including successful aging, lower depression, and longevity. Interventions to enhance resilience within this population are warranted, but little evidence of success exists. Thus this review provides an overview of resilience that may aid in the design of resilience interventions for the often underserved population of older adults.

    A program of research conducted within an anti-agism paradigm demonstrates that young people process and respond to the speech of older people in stereotypical ways. Such conclusions result from studies using a variety of research methods. Experimental studies demonstrate that older-sounding speech triggers age schematic responses and that young people tend to use agist strategies of information seeking and compliance gaining from older people, while interactive studies explore how stereotypes and age identities are co-produced by young and old people in conversation. We use lifespan and intercultural perspectives to argue that the communicative patterns we observe in our studies are in some senses and contexts counterproductive in both the long and short term, in that they can reproduce negative attitudes toward aging as well as inhibit successful aging.

    In 1999 we proposed a Modified Food Guide Pyramid for adults aged 70+ y. It has been extensively used in a variety of settings and formats to highlight the unique dietary challenges of older adults. We now propose a Modified MyPyramid for Older Adults in a format consistent with the MyPyramid graphic. It is not intended to substitute for MyPyramid, which is a multifunctional Internet-based program allowing for the calculation of individualized food-based dietary guidance and providing supplemental information on food choices and preparation. Pedagogic issues related to computer availability, Web access, and Internet literacy of older adults suggests a graphic version of MyPyramid is needed. Emphasized are whole grains and variety within the grains group; variety and nutrient density, with specific emphasis on different forms particularly suited to older adults' needs (e.g. frozen) in the vegetables and fruits groups; low-fat and non-fat forms of dairy products including reduced lactose alternatives in the milk group; low saturated fat and trans fat choices in the oils group; and low saturated fat and vegetable choices in the meat and beans group. Underlying themes stress nutrient- and fiber-rich foods within each group and food sources of nutrients rather than supplements. Fluid and physical activity icons serve as the foundation of MyPyramid for Older Adults. A flag to maintain an awareness of the potential need to consider supplemental forms of calcium, and vitamins D and B-12 is placed at the top of the pyramid. Discussed are newer concerns about potential overnutrition in the current food landscape available to older adults. PMID:18156396

  12. Communication barriers between older women and physicians.

    1987-01-01

    Communication barriers between health care providers and older women are multifaceted and complex. The acute care, hospital-based orientation of the health care system tends to bypass the characteristic problems of older women who need services. Breakdown in communication originates both with the provider and the recipient. Some inherent changes of aging due to sensory loss may be a major factor. Decline in vision, hearing, and touch make communication difficult for both parties. Other deficits may occur due to disease processes such as diabetes and hypertension. A frequently ignored problem is that of the language barrier between laywomen and physicians. Use of jargon and a nonempathic interviewing style by the doctor tend to discourage free exchange of information. A third consideration is the many psychosocial factors which affect the behavior of older women and their relationship with providers. One element is the belief in negative stereotypes of women in general, and older women in particular. Fear of being labeled a "hypochondriac," a "nuisance," or a "crabby old woman" inhibits accurate reporting by patients. Attitudes toward doctors, especially male doctors, make some older women timid and fearful. Physician and patient alike may accept signs and symptoms of disease as a normal part of aging and may cause medically treatable problems to be overlooked. Finally, patient and physician priorities may differ widely. The belief by either party that wellness, prevention, and health promotion are not realistic goals for the older women may push the individual patient into premature frailty and disability which could otherwise be postponed.

    Purpose The aim of this paper is to demonstrate how informatics applications can support the assessment and visualization of older adults’ wellness. A theoretical framework is presented that informs the design of a technology enhanced screening platform for wellness. We highlight an ongoing pilot demonstration in an assisted living facility where a community room has been converted into a living laboratory for the use of diverse technologies (including a telehealth component to capture vital signs and customized questionnaires, a gait analysis component and cognitive assessment software) to assess the multiple aspects of wellness of older adults. Methods A demonstration project was introduced in an independent retirement community to validate our theoretical framework of informatics and wellness assessment for older adults. Subjects are being recruited to attend a community room and engage in the use of diverse technologies to assess cognitive performance, physiological and gait variables as well as psychometrics pertaining to social and spiritual components of wellness for a period of eight weeks. Data are integrated from various sources into one study database and different visualization approaches are pursued to efficiently display potential correlations between different parameters and capture overall trends of wellness. Results Preliminary findings indicate that older adults are willing to participate in technology-enhanced interventions and embrace different information technology applications given appropriate and customized training and hardware and software features that address potential functional limitations and inexperience with computers. Conclusion Informatics can advance health care for older adults and support a holistic assessment of older adults’ wellness. The described framework can support decision making, link formal and informal caregiving networks and identify early trends and patterns that if addressed could reduce adverse health events

    Pressure ulcers are painful and cause discomfort, have a negative effect on quality of life, and are costly to treat. The incidence and severity of preventable pressure ulcers is an important indicator of quality of care; it is essential that healthcare providers monitor prevalence and incidence rates to ensure that care strategies implemented are effective. Frail older people are at increased risk of developing pressure ulcers. This article discusses the complexities of preventing pressure ulcers in frail older people and emphasises the importance of structured educational programmes that incorporate effective clinical leadership and multidisciplinary teamwork.

    2016-08-01

    The older adult patient with syncope is one of the most challenging evaluations for the emergency physician. It requires clinical skill, patience, and knowledge of specific older adult issues. It demands care in the identification of necessary resources, such as medication review, and potential linkage with several multidisciplinary follow-up services. Excellent syncope care likely requires reaching out to ensure institutional resources are aligned with emergency department patient needs, thus asking emergency physicians to stretch their administrative talents. This is likely best done as preset protocols prior to individual patient encounters. Emergency physicians evaluate elders with syncope every day and should rise to the challenge to do it well.

    Aging for the older women in the 21st century is more than medical issues. In this study, 62 women (ages 51-81+) obtained a total of 97 permanent makeup procedures. Procurement cues included self-improvement and friend's appearance, consistent with internal, external, and appearance perspectives of body image. Poor eyesight was also of concern (14/23%). Actual benefits included saving makeup time and money (external), while achieving personal goals (internal). This study seems to confirm that for these older women, body image remains important, especially qualities of the face. They did not shed their internal, external, nor appearance concerns associated with body image, as they aged.

    Cultural variations in the perception of depression make it difficult to recognize the disorder resulting in older Hispanics not being diagnosed and not receiving appropriate treatment. This study used a mixed-method design to explore older Hispanics' explanatory model of depression. Depression was recognized as the result of life stressors and personal weaknesses. Terms used for depressed people included "crazy, worry, bored, and nerves." These culturally coded terms may confound diagnosis among many Hispanics who find depression a shameful condition. Findings can be used to inform the adaptation of culturally relevant approaches to better serve the Hispanic community in this country.

    Treatment for colorectal cancer should not be based on age alone. Pooled analyses from clinical trials show that fit older adults are able to tolerate treatment well with similar efficacy as younger adults. When an older adult is considered for treatment, the clinical encounter must evaluate for deficits in physical and cognitive function, and assess comorbidities, medications, and the degree of social support, all which have may affect tolerance of treatment. Based on the degree of fitness of the patient, multiple alternatives to aggressive treatment regimens and strategies exist to minimize toxicity and preserve quality of life during treatment.

Of the 52 older female caregivers with a mean age of 65 years (range 50-90) interviewed by telephone, 80.8% had had a mammogram within 12 months. Significant facilitators included health care provider recommendation and beliefs in the efficacy of treatment. Significant barriers included health care providers' failure to recommend mammograms, caregiver procrastination, fear of pain, and lack of symptoms. Caregivers with higher burden reported less frequent self- and provider-conducted breast examinations.

    Dehydration is common in older people, leading to longer hospital stays and increased disability and mortality. Health professionals can diagnose water-loss dehydration by taking a blood sample and measuring serum osmolality, but a less-invasive test would be useful. Evidence that tests, clinical signs or questions tested to date are useful when screening for dehydration in older people is limited. This article looks at known risk factors, signs and test for dehydration, and outlines evidence on how useful they have proven to be. Part 2 describes how a care home has used a multicomponent strategy to improve hydration. PMID:26455128

    The health challenges prompted by obesity in the older adult population are poorly recognized and understudied. A defined treatment of geriatric obesity is difficult to establish, as it must take into account biological heterogeneity, age-related comorbidities, and functional limitations (sarcopenia/dynapenia). This retrospective article highlights the current understanding of the optimal body mass index (BMI) in later life, addressing appropriate recommendations based on BMI category, age, and health history. The findings of randomized control trials of weight loss/maintenance interventions help one to move closer to evidence-based and appropriately individualized recommendations for body weight management in older adults.

    Leisure animals now comprise the majority of working horses in industrialized nations; a shift that has decreased workloads yet improved veterinary care and lifetime health. Although many horses now progress well into their 20s without any requirement for dietary modification, age-related changes are insidious, and older animals benefit from regular veterinary monitoring to identify, address, and ameliorate the inevitable onset of age-related "disease." Basal metabolic rate decreases with age; older animals expend less energy on controlled exercise, and there can be an increased propensity toward the development of obesity, which needs to be recognized and managed.

    We used eye-tracking technology to examine young and older adults' performance in the reading with distraction paradigm. One-, 2- and 4-word distracters that formed meaningful phrases were used. There were marked age differences in fixation patterns. Young adults' fixations to the distracters and targets increased with distracter length, suggesting that they were attempting to integrate the distracters with the sentence and had more and more difficulty doing so as the distracters increased in length. Young adults did have better comprehension of the sentences than older adults and also better recognition memory for target words and distracters.

    2015-01-01

    Objective: The purpose of our study was to describe the quality of life of older adults with seizures or epilepsy and compare its psychosocial impact between those who were new diagnosed and those diagnosed before the age of 65. Methods: In-depth face to face interviews with open ended questions were conducted with two participant groups: Incident group: 42 older adults (>65 years) with new onset or newly diagnosed after age of 65; and Prevalent group: 15 older adults (>65 years) diagnosed before age of 65. Interviews were reviewed and coded using a list of themes and results were compared between the two groups. Eight topics were selected from the participants’ responses to questions about the psychosocial impact of epilepsy and seizures. The topics were then analyzed and compared between the two groups. Results: The topics analyzed were: Emotional and physical impact, significant life changes, co-morbidities, information gathering, stigma, AED side effects, changes in relationships and attitude toward diagnosis. Conclusion: We concluded that the age at onset and duration does seem to have a negative correlation with health related quality of life. However, the perceived health status of older adults with chronic epilepsy was significantly better and reflected in their more positive approach to the diagnosis of seizures or epilepsy probably because they have had a longer opportunity to learn to cope with their diagnosis.

  17. Chronic Eccentric Exercise and the Older Adult.

    PubMed

    Gluchowski, Ashley; Harris, Nigel; Dulson, Deborah; Cronin, John

    2015-10-01

    Eccentric exercise has gained increasing attention as a suitable and promising intervention to delay or mitigate the known physical and physiological declines associated with aging. Determining the relative efficacy of eccentric exercise when compared with the more conventionally prescribed traditional resistance exercise will support evidence-based prescribing for the aging population. Thus, original research studies incorporating chronic eccentric exercise interventions in the older adult population were included in this review. The effects of a range of eccentric exercise modalities on muscular strength, functional capacity, body composition, muscle architecture, markers of muscle damage, the immune system, cardiovascular system, endocrine system, and rating of perceived exertion were all reviewed as outcomes of particular interest in the older adult. Muscular strength was found to increase most consistently compared with results from traditional resistance exercise. Functional capacity and body composition showed significant improvements with eccentric endurance protocols, especially in older, frail or sedentary cohorts. Muscle damage was avoided with the gradual progression of novel eccentric exercise, while muscle damage from intense acute bouts was significantly attenuated with repeated sessions. Eccentric exercise causes little cardiovascular stress; thus, it may not generate the overload required to elicit cardiovascular adaptations. An anabolic state may be achievable following eccentric exercise, while improvements to insulin sensitivity have not been found. Finally, rating of perceived exertion during eccentric exercise was often significantly lower than during traditional resistance exercise. Overall, evidence supports the prescription of eccentric exercise for the majority of outcomes of interest in the diverse cohorts of the older adult population.

  18. [Approach to hypertension in the older population].

    PubMed

    Roca, Francisco Valls

    2014-05-01

    Hypertension is one of the most frequent causes for seeking primary care attention and its prevalence increases with age, affecting 68% of people older than 60 years. Data indicate that the prevalence of hypertense individuals older than 65 years has increased from 48% in 2002 to 58% in 2010. High blood pressure is related to 1 out of every 2 deaths from cardiovascular causes in the Spanish population ≥ 50 years and causes 13.5% of premature deaths worldwide, both in persons with hypertension and in those with high-normal blood pressure. Although few clinical trials have been performed in the older population, especially in the very old, there is evidence that diastolic and systolic blood pressure control reduces cardiovascular morbidity and mortality in older hypertense individuals. Consequently, the updates of the various clinical practice guidelines continue to include among their objectives-with some nuances-good blood pressure control in this population group. The present article reviews new evidence on the approach to hypertension in the elderly, which has modified some of the recommendations made in the clinical practice guidelines of several scientific societies.

  2. Older adults have difficulty in decoding sarcasm.

    PubMed

    Phillips, Louise H; Allen, Roy; Bull, Rebecca; Hering, Alexandra; Kliegel, Matthias; Channon, Shelley

    2015-12-01

    Younger and older adults differ in performance on a range of social-cognitive skills, with older adults having difficulties in decoding nonverbal cues to emotion and intentions. Such skills are likely to be important when deciding whether someone is being sarcastic. In the current study we investigated in a life span sample whether there are age-related differences in the interpretation of sarcastic statements. Using both video and verbal materials, 116 participants aged between 18 and 86 completed judgments about whether statements should be interpreted literally or sarcastically. For the verbal stories task, older adults were poorer at understanding sarcastic intent compared with younger and middle-aged participants, but there was no age difference in interpreting control stories. For the video task, older adults showed poorer understanding of sarcastic exchanges compared with younger and middle-aged counterparts, but there was no age difference in understanding the meaning of sincere interactions. For the videos task, the age differences were mediated by the ability to perceive facial expressions of emotion. Age effects could not be explained in terms of variance in working memory. These results indicate that increased age is associated with specific difficulties in using nonverbal and contextual cues to understand sarcastic intent. (PsycINFO Database Record PMID:26501728

  6. THE OLDER ADULT DRIVER WITH COGNITIVE IMPAIRMENT

    PubMed Central

    Carr, David B.; Ott, Brian R.

    2010-01-01

    Although automobiles remain the transportation of choice for older adults, late life cognitive impairment and dementia often impair the ability to drive safely. There is, however, no commonly utilized method of assessing dementia severity in relation to driving, no consensus on the assessment of older drivers with cognitive impairment, and no gold standard for determining driving fitness. Yet, clinicians are called upon by patients, their families, other health professionals, and often the Department of Motor Vehicles (DMV) to assess their patients' fitness-to-drive and to make recommendations about driving privileges. Using the case of Mr W, we describe the challenges of driving with cognitive impairment for both the patient and caregiver, summarize the literature on dementia and driving, discuss evidenced-based assessment of fitness-to-drive, and address important ethical and legal issues. We describe the role of physician assessment, referral to neuropsychology, functional screens, dementia severity tools, driving evaluation clinics, and DMV referrals that may assist with evaluation. Finally, we discuss mobility counseling (eg, exploration of transportation alternatives) since health professionals need to address this important issue for older adults who lose the ability to drive. The application of a comprehensive, interdisciplinary approach to the older driver with cognitive impairment will have the best opportunity to enhance our patients' social connectedness and quality of life, while meeting their psychological and medical needs and maintaining personal and public safety.

    Wiener, R Constance; Shockey, Alcinda Trickett; Long, D Leann

    2014-12-01

    Geriatric education is an important component of the dental hygiene curriculum because, in it, students acquire skills and attitudes to help provide quality care to older adults. The purpose of this study was to determine if off-site exposure to nursing home residents with supervised oversight had the potential to improve dental hygiene students' attitudes toward older adults. Senior dental hygiene students at one school completed a pre-nursing home experience questionnaire. A series of geriatric lectures and discussions, which included discussions about students' anxieties of working with institutionalized older adults, were held prior to the nursing home experience. The students then participated in two supervised four-hour nursing home experiences, were debriefed after the experiences, and completed a second questionnaire. Of thirty-nine potential participants in the study, thirty-two took part in the pre-nursing home experience questionnaire (82.1 percent). They had a mean split Fabroni score of 34.2 (95 percent confidence interval: 32.2, 36.3). The thirty participants in the post-experience questionnaire (76.9 percent of total) had a mean split score of 32.7 (95 percent confidence interval: 30.1, 35.3). This study failed to reject the null hypothesis of no mean difference between the pre- and post-nursing home experience; however, the post-experience mean score was lower than the pre-nursing home experience mean score, indicating a more positive attitude toward older adults after the experience.

    PubMed

    Dollberg, S; Seidman, D S; Armon, Y; Stevenson, D K; Gale, R

    1996-01-01

    Delayed childbearing has become common and has raised the awareness of the possible risks for the mother and the newborn infant. The increased maternal and neonatal risks have been attributed largely to the lack of proper prenatal care. The aim of this study was to assess whether advanced maternal age is a significant risk factor in mothers who receive good prenatal care. We matched 161 cases 1:1 according to the following criteria: maternal and paternal ethnic origin, chronic diseases, marital status, and smoking during pregnancy. Our results show that the older women had babies with a significantly higher incidence of low birth weight (< 2500 gm, p = 0.001), prematurity (< 37 weeks, p = 0.02), intrauterine growth retardation (p = 0.001), abruptio placentae (p = 0.002), and cesarean section (p < 0.001). The average hospital stay for the babies of the older mothers was longer than that for babies of the younger mothers (8.4 vs 6.1 days, p = 0.003), and the incidence of hospitalization for more than 3 days in the neonatal intensive care unit was increased (10.3% vs 2.2%). Logistic regression did not support maternal age of 35 years and older as being the single significant risk factor for adverse neonatal and maternal outcome. We conclude that maternal age older than 35 years entails a higher risk for the mother and her newborn infant, even when good prenatal care is taken.

  3. Delirium and older people: repositioning nursing care.

    PubMed

    Neville, Stephen

    2006-06-01

    Aims.  To critically examine the nursing care offered to older people who have been delirious. Background.  Delirium occurs as a result of physiological imbalances resulting in an alteration in consciousness and cognitive impairment. Delirium is a prevalent and serious cognitive disorder experienced by older people. While there is a vast number of studies published utilizing quantitative methods, there remains a dearth of research relating to delirium in older people from a qualitative perspective. Design.  A qualitative research design that utilized a critical gerontological framework underpinned this study. This framework drew on aspects of postmodernism and Foucault's understanding of discourse. Methods.  Data sources included published documents on delirium, semi-structured taped interviews with people over the age of 65 years who had been delirious (as well as their clinical notes), family members, Registered Nurses and a hospital doctor. A postmodern discourse analytic approach was used to interrogate the 20 sets of data collected. Findings.  Textual analysis revealed the presence of two major discourses impacting on being an older person with delirium. These were identified as a nursing discourse of delirium and a personal discourse of delirium. A nursing discourse of delirium was largely focussed on the biomedical processes that resulted in a delirious episode. Conversely, a personal discourse of delirium highlights that there are other ways of 'knowing' about delirium through considering the narratives of older adults, and their families, when offering a nursing service to this group of people. Relevance to clinical practice.  Nursing needs to critically examine all aspects of nursing care as it applies to older people who have delirium to ensure the rhetorical claims of the profession become the reality for consumers of health services. The use of critical gerontology provides nurses with the tools to challenge the status quo and uncover the

  4. Child's play: the creativity of older adults.

    PubMed

    Capps, Donald

    2012-09-01

    In this article, I discuss Paul W. Pruyser's view presented in his article "An Essay on Creativity" (Pruyser in Bull Menninger Clin 43:294-353, 1979) that creative persons manifest early childhood qualities of playfulness, curiosity, and pleasure seeking and that adaptation is itself a form of creativity. I then discuss his article "Creativity in Aging Persons" (Pruyser in Bull Menninger Clin 51:425-435, 1987) in which he presents his view that aging itself is a potentially creative process, that creativity among older adults is not limited to the talented few, and that older adulthood has several specific features that are conducive to creativity. Significant among these features are object loss (especially involving human relationships) and functional loss (due to the vicissitudes of aging). Noting his particular emphasis on object loss and its role in late-life creativity, I focus on functional loss, and I emphasize the importance of adaptation in sustaining the creativity of older adults who experience such loss. I illustrate this adaptation by considering well-known painters who in late life suffered visual problems common to older adults. I suggest that in adapting to their visual problems these artists drew on the early childhood qualities (playfulness, curiosity and pleasure seeking) that all creative persons possess and that they are therefore illustrative for other older adults who are experiencing functional losses. I conclude with Erik H. Erikson's (Toys and reasons: stages in the ritualization of experience, W. W. Norton, New York, 1977) and Paul W. Pruyser's (Pastor Psychol 35:120-131, 1986) reflections on the relationship between seeing and hoping.

    2004-01-01

    OBJECTIVE: To provide family physicians with an approach to managing skin ulcers in older patients. SOURCES OF INFORMATION: Clinical practice guidelines and best practice guidelines were summarized to describe an evidence-based approach. MAIN MESSAGE; Preventing ulcers is important in frail older patients. Using guidelines can help prevent ulcers in institutions. Clarifying the cause and contributing factors is the first step in management. Pressure and venous ulcers are common in elderly people. Poor nutrition, edema, arterial insufficiency, and anemia often impair wound healing. Adequate debridement is important to decrease risk of infection and to promote healing. There are guidelines for cleaning ulcers. Choice of dressings depends on the circumstances of each wound, but dressings should provide a moist environment. Options for dressings are summarized. CONCLUSION: Family physicians can manage skin ulcers effectively by applying basic principles and using readily available guidelines. PMID:15648380

    With rising longevity, increasing numbers of older people are experiencing changes in their everyday family and social life, changes in their financial status, and a greater number of chronic conditions affecting their health. We took the opportunity to explore these relationships with worry in a group of volunteer community-living elderly (n = 310). Findings showed that that those people under 75 years of age had a higher risk of worrying (OR = 1.8, 95% CI = 1.0-3.1) compared to the older age groups. Women worried more than men and an important finding was that those with chronic health conditions such as arthritis of the hip and knee were more prone to worry than those who were healthy or had acute conditions (OR = 3.5, 95% CI = 1.4-8.9). This latter finding suggests the importance placed on the role of the hip and knee in maintaining functional capacity to perform life skills. PMID:21977675

    2012-01-01

    The global population is aging. In many industrial countries, almost one in five people are over age 65. As people age, gradual changes ensue in vision, hearing, balance, coordination, and memory. Products, communication materials, and the physical environment must be thoughtfully designed to meet the needs of people of all ages. This article summarizes normal changes in sensory function, mobility, balance, memory, and attention that occur with age. It presents practical guidelines that allow design professionals to accommodate these changes and better meet the needs of older adults. Designing for older adults is inclusive design: it accommodates a range of physical and cognitive abilities and promotes simplicity, flexibility, and ease of use for people of any age. PMID:22980147

  13. Eye Conditions in Older Adults: Diabetic Retinopathy.

    PubMed

    Kirsch, Scott; Iroku-Malize, Tochi

    2016-06-01

    Diabetic retinopathy is related to neovascularization of the retina stimulated by an elevated blood glucose level. This can lead to macular edema, vascular hemorrhage, retinal detachment, and neovascular glaucoma. Diabetic retinopathy is a leading cause of blindness in the United States, and is estimated to affect between 28% and 40% of patients older than 40 years. Significant visual deficit from diabetic retinopathy can lead to social isolation of older individuals by limiting driving, the ability to leave the home or remain in the home safely, and the ability to watch television or read. Primary and secondary prevention includes adequate control of A1c levels. Screening is important for early detection of ocular damage and intervention. Retinal benefits of therapy may predict cardiovascular benefits over a longer period. PMID:27348530

    2016-05-01

    In older adults, the clinical condition of COPD is complicated and treatment often becomes difficult, because of existence of multimorbidity, such as nutritional deficiencies, thinness, sarcopenia, osteoporosis, cardiovascular disease, depression and cognitive impairment. Consideration based on each of coexistence is needed in the management of older adults with COPD. In end period of COPD, sleep disorder, depressive state and decline of ADL are often shown, in addition to the respiratory symptoms, such as dyspnea, cough and sputum. Financial strain for the nursing cost and medical equipment cost tend to become big year by year, utilization of social resources (i.e. application of respiratory disabilities and an insurance of the elderly care) is need to be considered.

    Amer, Tarek; Kalender, Beste; Hasher, Lynn; Trehub, Sandra E; Wong, Yukwal

    2013-01-01

    The current study investigates whether long-term music training and practice are associated with enhancement of general cognitive abilities in late middle-aged to older adults. Professional musicians and non-musicians who were matched on age, education, vocabulary, and general health were compared on a near-transfer task involving auditory processing and on far-transfer tasks that measured spatial span and aspects of cognitive control. Musicians outperformed non-musicians on the near-transfer task, on most but not all of the far-transfer tasks, and on a composite measure of cognitive control. The results suggest that sustained music training or involvement is associated with improved aspects of cognitive functioning in older adults.

    OBJECTIVE To analyze the perception of and motivation for the chronic use of benzodiazepine among older adults. METHODS A qualitative study was conducted on 22 older adults living in Bambuí, MG, Southeastern Brazil, who were taking benzodiazepines and had the clinical and cognitive ability to respond to interview questions. The collected data were analyzed on the basis of the “signs, meanings, and actions” model. RESULTS The main reasons pointed out for the use of benzodiazepines were “nervousness”, “sleep problems”, and “worry” due to family and financial problems, everyday problems, and existential difficulties. None of the interviewees said that they used benzodiazepines in a dose higher than that recommended or had been warned by health professionals about any risks of their continuous use. Different strategies were used to obtain the prescription for the medication, and any physician would prescribe it, indicating that a bond was established with the drug and not with the health professional or healthcare service. Obtaining and consuming the medication turned into a crucial issue because benzodiazepine assumes the status of an essential food, which leads users to not think but sleep. It causes a feeling of relief from their problems such as awareness of human finitude and fragility, existential difficulties, and family problems. CONCLUSIONS Benzodiazepine assumes the characteristics of polyvalence among older adults, which extrapolate specific clinical indications, and of essentiality to deal with life’s problems in old age. Although it relieves the “nerves”, the chronic use of benzodiazepines buffers suffering and prevents older adults from going through the suffering. This shows important difficulties in the organization and planning of strategies that are necessary for minimizing the chronic use in this population. PMID:26039388

    Antibiotic use is common in older adults, and much of it is deemed unnecessary. Complications of antibiotic use may occur as a consequence of changes in age-related physiology and dosing with resulting drug toxicity and secondary infection. Knowing when it is appropriate to initiate antibiotics may help reduce unnecessary antibiotic use and prevent adverse drug events. Careful attention to antibiotic selection, dosing adjustments, and drug-drug interactions may also help prevent antibiotic-related adverse events.

    2015-01-01

    Geriatric education is an important component of the dental hygiene curriculum because, in it, students acquire skills and attitudes to help provide quality care to older adults. The purpose of this study was to determine if off-site exposure to nursing home residents with supervised oversight had the potential to improve dental hygiene students’ attitudes toward older adults. Senior dental hygiene students at one school completed a pre-nursing home experience questionnaire. A series of geriatric lectures and discussions, which included discussions about students’ anxieties of working with institutionalized older adults, were held prior to the nursing home experience. The students then participated in two supervised four-hour nursing home experiences, were debriefed after the experiences, and completed a second questionnaire. Of thirty-nine potential participants in the study, thirty-two took part in the pre-nursing home experience questionnaire (82.1 percent). They had a mean split Fabroni score of 34.2 (95 percent confidence interval: 32.2, 36.3). The thirty participants in the post-experience questionnaire (76.9 percent of total) had a mean split score of 32.7 (95 percent confidence interval: 30.1, 35.3). This study failed to reject the null hypothesis of no mean difference between the pre- and post-nursing home experience; however, the post-experience mean score was lower than the pre-nursing home experience mean score, indicating a more positive attitude toward older adults after the experience.

  1. REPORTING PEAK EXPIRATORY FLOW IN OLDER PERSONS

    PubMed Central

    Vaz Fragoso, Carlos A.; Gahbauer, Evelyne A.; Van Ness, Peter H.; Gill, Thomas M.

    2009-01-01

    Background Peak expiratory flow (“peak flow”) predicts important outcomes in older persons. Nevertheless, its clinical application is uncertain because prior strategies for reporting peak flow may not be valid. We thus determined the frequency distribution of peak flow by the conventional strategy of percent predicted (%predicted) and by an alternative method termed standardized residual (SR) percentile, and evaluated how these two metrics relate to health status in older persons. Methods Participants included 754 community-living persons aged ≥ 70 years. Data included chronic conditions, frailty indicators, and peak flow. Results Mean age was 78.4 years, with 63.7% reporting a smoking history, 17.4% chronic lung disease, and 77.1% having one or more frailty indicators. Peak flow ≥ 80 %predicted was recorded in 67.5% of participants, whereas peak flow ≥ 80th SR-percentile was only noted in 15.9%. A graded relationship was observed between peak flow and health status, but %predicted yielded health risk at peak flows currently considered normal (80–100 %predicted), whereas SR-percentile conferred health risk only at severely reduced peak flows (< 50th SR-percentile). Conclusions Peak flow expressed as SR-percentile attains a frequency distribution more consistent with the characteristics of our elderly cohort, and establishes health risk at more appropriate levels of reduced peak flow. These findings establish the need for longitudinal studies based on SR-percentile to further evaluate the use of peak flow as a risk assessment tool in older persons, and to determine if pulmonary function, in general, is better reported in older persons as SR-percentile, rather than as %predicted.

    2016-08-01

    Cancer is primarily a disease of older adults. The treatment of advanced stage tumors usually involves the use of systemic agents that may be associated with significant risk of toxicity, especially in older patients. Immune checkpoint inhibitors are newcomers to the oncology world with improved efficacy and better safety profiles when compared to traditional cytotoxic drugs. This makes them an attractive treatment option. While there are no elderly specific trials, this review attempts to look at the current available data from a geriatric oncology perspective. We reviewed data from phase III studies that led to newly approved indications of checkpoint inhibitors in non-small cell lung cancer, melanoma, and renal cell cancer. Data were reviewed with respect to response, survival, and toxicity according to three groups: <65 years, 65-75 years, and >75 years. Current literature does not allow one to draw definitive conclusions regarding the role of immune checkpoint inhibitors in older adults. However, they may offer a potentially less toxic but equally efficacious treatment option for the senior adult oncology patient. PMID:27287329

    2012-06-01

    In Canada's multicultural society, ethnic identity is important to the elderly and can influence areas such as access to services, health promotion and care. Often, the complex nature of ethnic identity is underestimated when looking at cultural groups. This study aims to: (a) validate the factor structure of a Chinese ethnic identity measure for older Chinese in Canada, (b) examine the level of ethnic identity of the participants, and (c) examine the correlates of ethnic identity in these older individuals. Using data from a large, national research project on the elderly Chinese in Canada, this study analyzed the results gathered from a total of 2,272 participants. Principal component analysis, maximum-likelihood confirmatory factor analysis, and multiple regression analysis were performed. The results indicated that ethnic identity of the older Chinese is a multi-dimensional construct made up of three factors: (a) culture related activities, (b) community ties, (c) linkage with country of origin, and (d) cultural identification. The findings have provided a better understanding of how ethnic identity can be measured among the aging Chinese population in Canada.

  8. The Mental Health of Older LGBT Adults.

    2016-06-01

    There are approximately one million older lesbian, gay, bisexual, and transgender (LGBT) adults in the USA. Their mental health issues result from interactions between genetic factors and stress associated with membership in a sexual minority group. Although advancements in acceptance and equal treatment of LGBT individuals have been occurring, sexual minority status remains associated with risks to physical and mental well-being. Older LGBT adults are more likely to have experienced mistreatment and discrimination due to living a majority of their lives prior to recent advancements in acceptance and equal treatment. All LGBT adults experience one common developmental challenge: deciding if, when, and how to reveal to others their gender identity and/or sexual orientation. LGBT individuals have higher rates of anxiety, depression, and substance use disorders and also are at increased risk for certain medical conditions like obesity, breast cancer, and human immunodeficiency virus (HIV). Improved education and training of clinicians, coupled with clinical research efforts, holds the promise of improved overall health and life quality for older LGBT adults.

  9. Managing Status Epilepticus in the Older Adult

    The aim of this systematic review was to describe particularities in epidemiology, outcome, and management modalities in the older adult population with status epilepticus. There is a higher incidence of status epilepticus in the older adult population, and it commonly has a nonconvulsive presentation. Diagnosis in this population may be difficult and requires an unrestricted use of EEG. Short and long term associated-mortality are high, and age over 60 years is an independent factor associated with poor outcome. Stroke (acute or remote symptomatic), miscellaneous metabolic causes, dementia, infections hypoxemia, and brain injury are among the main causes of status epilepticus occurrence in this age category. The use of anticonvulsive agents can be problematic as well. Thus, it is important to take into account the specific aspects related to the pharmacokinetic and pharmacodynamic changes in older critically-ill adults. Beyond these precautions, the management may be identical to that of the younger adult, including prompt initiation of symptomatic and anticonvulsant therapies, and a broad and thorough etiological investigation. Such management strategies may improve the vital and functional prognosis of these patients, while maintaining a high overall quality of care. PMID:27187485

  10. Sexual Consent Capacity Assessment with Older Adults.

    2016-09-01

    Many healthcare providers have a limited knowledge of sexual and intimate expression in later life, often due to attitudinal and informational limitations. Further, the likelihood of an older adult experiencing cognitive decline increases in a long-term care (LTC) setting, complicating the ability of the providers to know if the older adult can make his or her own sexual decisions, or has sexual consent capacity. Thus, the team is left to question if and how to support intimacy and/or sexuality among residents with intimacy needs. Psychologists working with LTC need to be aware and knowledgeable about sexual consent capacity in older adulthood to be prepared to conduct evaluations and participate in planning care. Limited research is available to consult for best practices in sexual consent capacity assessment; however, models of assessment have been developed based on the best available evidence, clinical judgment, and practice. Existing models will be discussed and an integrated model will be illustrated via a case study. PMID:27480989

    There are approximately one million older lesbian, gay, bisexual, and transgender (LGBT) adults in the USA. Their mental health issues result from interactions between genetic factors and stress associated with membership in a sexual minority group. Although advancements in acceptance and equal treatment of LGBT individuals have been occurring, sexual minority status remains associated with risks to physical and mental well-being. Older LGBT adults are more likely to have experienced mistreatment and discrimination due to living a majority of their lives prior to recent advancements in acceptance and equal treatment. All LGBT adults experience one common developmental challenge: deciding if, when, and how to reveal to others their gender identity and/or sexual orientation.

    As an older woman therapist, I find that my life experience grounds me in my work with people of all ages and backgrounds as they deal with life crises, aging issues, and loss. People with whom I work in therapy appreciate the fact that I am older and have had varied life experiences. Gender issues are still central to my work with clients whether I am working with a man or a woman. I am an integrative therapist, with a background in cognitive-behavioral therapy and gestalt therapy. Therapists need to help clients to identify less with their aging bodies and our culture's view of attractiveness, shifting instead to a paradigm that values life experience and the cultivation of wisdom. We need to find ways of embracing what we have learned about life instead of extolling youthful values. As I get older, I more fully appreciate a constructivism framework and life-cycle perspective, focusing on making sense of clients' life narratives. Storytelling and memoirs have both provided a framework for working with clients on coping with the many changes and challenges of life that bring them to therapy and added another layer to my integrative therapeutic work.

  13. Physical activity is medicine for older adults

    2014-01-01

    There is evidence from high quality studies to strongly support the positive association between increased levels of physical activity, exercise participation and improved health in older adults. Worldwide, around 3.2 million deaths per year are being attributed to inactivity. In industrialised countries where people are living longer lives, the levels of chronic health conditions are increasing and the levels of physical activity are declining. Key factors in improving health are exercising at a moderate-to-vigorous level for at least 5 days per week and including both aerobic and strengthening exercises. Few older adults achieve the level of physical activity or exercise that accompanies health improvements. A challenge for health professionals is to increase physical activity and exercise participation in older adults. Some success in this has been reported when physicians have given specific, detailed and localised information to their patients, but more high quality research is needed to continue to address this issue of non-participation in physical activity and exercise of a high enough level to ensure health benefits.

    Cancer is primarily a disease of older adults. The treatment of advanced stage tumors usually involves the use of systemic agents that may be associated with significant risk of toxicity, especially in older patients. Immune checkpoint inhibitors are newcomers to the oncology world with improved efficacy and better safety profiles when compared to traditional cytotoxic drugs. This makes them an attractive treatment option. While there are no elderly specific trials, this review attempts to look at the current available data from a geriatric oncology perspective. We reviewed data from phase III studies that led to newly approved indications of checkpoint inhibitors in non-small cell lung cancer, melanoma, and renal cell cancer. Data were reviewed with respect to response, survival, and toxicity according to three groups: <65 years, 65-75 years, and >75 years. Current literature does not allow one to draw definitive conclusions regarding the role of immune checkpoint inhibitors in older adults. However, they may offer a potentially less toxic but equally efficacious treatment option for the senior adult oncology patient.

    The increased need for both personal assistance workers and meaningful employment opportunities for older workers results in growing numbers of older home care aides. This study examined lifetime financial security and perceived advantages of older age in this field through interviews with 31 older home care aides. Study participants experienced high levels of financial insecurity and perceived older workers as particularly well suited to the home care job. The consequences of this low-wage, low-status work are explored along with implications for social workers to advocate for improved conditions for these workers providing essential care to frail elders.

    Attitudes toward older people and older patients among healthcare professionals are of concern throughout the world, but there are no recent systematic reviews which have examined and compared the attitudes across the various healthcare professionals who provide healthcare to older people. A comprehensive literature search (2000-2011) was undertaken on electronic databases (CINAHL, MEDLINE, EMBASE, British Nursing Index, PsycINFO, Chinese Biomedical database, China Medical Academic Conference and China Academic Journal) using a combination of terms. We identified 2179 articles indexed with these terms. Initial screening was undertaken by two researchers and then checked by a third researcher. In total, the reviewers selected 117 articles which, on the basis of their abstracts, appeared to meet the criteria for inclusion. We obtained the full texts and two reviewers assessed each full text paper to further examine whether it met all the criteria. The final review identified 51 studies. Publications over the last 10 years show that attitudes towards older people and older patients range from neutral to positive among healthcare professionals and highlight the need for well-designed studies of both qualified and student healthcare professionals recruiting random samples across multiple sites and utilizing validated instruments consistently to permit comparison over time and across countries.

    In a series of 1-shot economic trust games in which participants could make real monetary profits, but also risked losing money, 2 studies compared young and older adults' trust (amount invested with trustees) and trustworthiness (amount returned to investors by trustees). In Study 1, young (n = 35) and older (n = 32) participants acted as investors, and the age of simulated trustees (young, older) was manipulated. In Study 2, young (n = 61) and older (n = 67) participants acted in real life as both investors and trustees. They completed 2 face-to-face trust games with same- and other-age partners, and 3 anonymous trust games with same-, other-, and unknown-age partners. Study 1 found that young and older participants rate older trustees as appearing more trustworthy than young trustees, but neither group invest more with older than young trustees. Rather, older participants were more likely than young participants to invest money averaged across trustee age. In Study 2, there were no age-related differences in trust, but older adults were more trustworthy than young adults in anonymous games with same- and unknown-age partners. It was also found that young adults demonstrate greater reputational concerns than older adults by reciprocating more trust when face-to-face than anonymous. We discuss the complex influences of age on trust game investing and reciprocation, as well as the implications for older adults' wellbeing and financial security.

  18. Nitrogen Balance and Protein Requirements for Critically Ill Older Patients

    PubMed Central

    Dickerson, Roland N.

    2016-01-01

    Critically ill older patients with sarcopenia experience greater morbidity and mortality than younger patients. It is anticipated that unabated protein catabolism would be detrimental for the critically ill older patient. Healthy older subjects experience a diminished response to protein supplementation when compared to their younger counterparts, but this anabolic resistance can be overcome by increasing protein intake. Preliminary evidence suggests that older patients may respond differently to protein intake than younger patients during critical illness as well. If sufficient protein intake is given, older patients can achieve a similar nitrogen accretion response as younger patients even during critical illness. However, there is concern among some clinicians that increasing protein intake in older patients during critical illness may lead to azotemia due to decreased renal functional reserve which may augment the propensity towards worsened renal function and worsened clinical outcomes. Current evidence regarding protein requirements, nitrogen balance, ureagenesis, and clinical outcomes during nutritional therapy for critically ill older patients is reviewed. PMID:27096868

    Persons aged 50 years and over will soon disproportionately represent the future of the HIV/AIDS epidemic. It is estimated that by 2015 older adults will represent 50% of persons living with HIV in the United States. Despite the HIV/AIDS growing population among older adults, attitudes, beliefs, and stereotypes toward older adults that exist in general society have affected HIV prevention, education, and care. Specifically, ageist attitudes about the sexuality of older adults in general and older women in particular, low clinical HIV suspicion among healthcare providers, lack of knowledge about risk among older women, and differentials in power related to negotiating sexual practices all lead to heightened concerns for the prevention, identification, and treatment of HIV disease in mature women. This article examines common attitudes, beliefs, and stereotypes that exist within general society as well as health and social service providers that place older women at a disadvantage when it comes to HIV prevention, education, and treatment.

    Organ transplantation has evolved into the standard of care for patients with end-stage organ failure. Despite considering increasingly complex transplant recipients for organs recovered from donors with increasing comorbid conditions, 1-year patient survival following kidney transplantation is 97% in the United States, whereas liver transplant recipient 1-year survival is 90%. There were 16,485 kidney recipients in the United States in 2012, and 6256 patients who underwent liver transplantation. The intent of this review is to highlight the logistics required for transplantation as well as reviewing the current oversight of transplantation.

  1. Getting Older Women Pregnant: Contemporary Thoughts.

    PubMed

    Allahbadia, Gautam N

    2016-10-01

    For women of advanced age with abnormally increased FSH levels, standardized hormonal stimulation often represents a cost-intensive procedure with a low success rate. It is well established now that with mild ovarian stimulation, there is a greater percentage of good-quality eggs (although a smaller number) than with higher-dose conventional stimulation. Mild stimulation protocols reduce the mean number of days of stimulation, the total amount of gonadotropins used and the mean number of oocytes retrieved. The proportion of high-quality and euploid embryos seems to be higher compared with conventional stimulation protocols, and the pregnancy rate per embryo transfer is comparable. Moreover, the reduced costs, the better tolerability for patients and the less time needed to complete an IVF cycle make mild approaches clinically and cost-effective over a given period of time. The low number of embryos available for transfer poses a great challenge in the management of older women going in for IVF. A potential management of these older women is to create a sufficient pool of embryos by accumulating vitrified good-grade embryos over several minimal stimulation and natural cycles. At the end of the accumulation process, these embryos can be subjected to a preimplantation genetic screening using next-generation sequencing and then the pool would have only chromosomal normal embryos with maximal chances of implantation. This would potentially make the chances of success for older women similar to normal responders. This management, however, is unthinkable without an outstanding vitrification program. The option of accumulating embryos has become a promising reality with the advent of vitrification technologies. PMID:27486273

    The diversion paradigm was created in the context of explaining the effect of the instruction to forget some recently encoded material in the list-method of the directed forgetting paradigm. The current study of healthy older adults employed the diversion paradigm with two main goals: to determine whether thinking about an autobiographical memory interferes with the recall of recently encoded information and to explore whether the degree of forgetting depends on the temporal distance created by the diversionary thought. Ninety non-institutionalized Portuguese older adults (47 females and 43 males), aged 65–69 years, with education levels of between 3 and 6 years participated in this study. The exclusion criteria were as follows: presence of depressive symptomatology (assessed with the Geriatric Depression Scale-30) and global cognitive deterioration (assessed with the Mini–Mental State Examination). Concerning the diversion paradigm, one group was instructed to think about an autobiographical event (remembering one’s childhood home or the last party that one had attended) after studying one word list (List 1) and before viewing the second word list (List 2). After a brief distraction task, the participant had to recall the words from both of the studied lists. In the control group, the procedure was the same, but the diversionary thought was substituted by a speed reading task. The obtained results showed the amnesic effect of diversionary thought but did not show a greater degree of forgetting when the autobiographical events in the diversionary thoughts were temporally more distant. Considering the practical implications of these results, this study alerts us to the importance of promoting strategies that enable older adults to better remember important information and effectively forget irrelevant information.

    The presence of sarcopenia is not only rapidly rising in geriatric clinical practice and research, but is also becoming a significant concept in numerous medical specialties. This rapidly rising concept has encouraged the need to identify methods for treating sarcopenia. Physical activity measures using resistance training exercise, combined with nutritional interventions (protein and amino acid supplementation) have shown to significantly improve muscle mass and strength in older persons. Moreover, resistance training may improve muscle strength and mass by improving protein synthesis in skeletal muscle cells. Aerobic exercise has also shown to hold beneficial impacts on sarcopenia by improving insulin sensitivity. At the moment, the literature indicates that most significant improvement in sarcopenia is based on exercise programs. Thus, this type of intervention should be implemented in a persistent manner over time in elders, with or at risk of muscle loss. At the same time, physical training exercise should include correcting nutritional deficits with supplementation methods. For example, in older sarcopenic patients with adequate renal function, daily protein intake should be increased to >1. 0 grams of protein per kilogram of body weight. In particular, leucine, - hydroxy β-methylbutyrate (HMB), creatine and some milk-based proteins have been shown to improve skeletal muscle protein balance. In addition, it is also recommended for adjustment of for vitamin D deficiency, if present, considering the crucial role of vitamin D in the skeletal muscle. In this review, we provide evidence regarding the effects of different physical exercise protocols, specific nutritional intervention, and some new metabolic agents (HMB, citrulline malate, ornithine, and others) on clinical outcomes related to sarcopenia in older adults.

    Background Older adults are susceptible to reduced saliva production related to certain medications, radiation and chronic conditions. Many of these people have many physical and oral health problems and limited access to dental care. The use of effective screening tools for xerostomia and hyposalivation would be helpful in identifying those at risk. The authors conducted a study to investigate the association between three measures of oral dryness: hyposalivation (low unstimulated salivary flow), self-reported xerostomia and clinically assessed dry mouth. Methods The authors included a convenience sample of 252 nondemented and dentate West Virginia participants 70 years and older who were part of a larger study on oral health and cognition among older adults. Participants completed a self-reported xerostomia index, provided an unstimulated salivary sample and underwent an oral assessment for the study. Results Twenty-eight (11.1 percent) had hyposalivation, eight of whom reported having xerostomia (sensitivity = 28.6 percent). Of the 43 participants who reported having xerostomia, only eight had hyposalivation (positive predictive value = 18.6 percent). Hyposalivation and self-reported xerostomia were not significantly related. Clinically assessed dry mouth correlated modestly, but significantly, with hyposalivation and self-reported xerostomia. Conclusions Obtaining routine unstimulated salivary flow rates in addition to self-reported information and oral evaluations may increase early detection of oral dryness, which would assist in implementing early interventions to improve patients’ quality of life. Clinical Implications Visually inspecting oral tissues for dryness and asking a patient if his or her mouth is dry are insufficient measures for clinicians to use to determine if the patient has hyposalivation. The authors recommend that clinicians determine the patients’ unstimulated salivary flow rate. PMID:20194383

    Older people are a major vulnerable population. During disasters, given their physical frailty, lower social status, loss of medications and medical care, the vulnerability of older people increases. The purpose of this study was to examine the perceptions of older people in Korea on various aspects of disaster preparedness to better understand their special needs and to facilitate appropriate disaster planning. The study was qualitative and used focus group interviews with 12 older people in one major city and one rural area of South Korea. Four themes were identified by the analysis of the interviews: defenceless state, reality of accepting limitations, strong will to live, importance of disaster preparedness governmental efforts for the older people. Findings indicated that preparation of shelters and transportation was critical to help older people survive in times of disasters and suggested that there should be active involvement of the government in terms of disaster planning, managing and preparing older people for disasters. In addition, healthy older people can be assets to disaster relief efforts by providing practical and emotional support for the most fragile older people. Older people can also provide knowledge of their special needs to the government to improve their disaster response policy.

    The impact of infectious diseases on older adults is far greater than on younger adults because of significantly higher morbidity and mortality caused by infection. The reasons for this greater impact include factors such as lower physiologic reserve due to age and chronic disease, age-related changes in host defenses, loss of mobility, higher risk for polypharmacy and adverse drug reactions, and being on drugs that increase the risk for infection (e.g., anticholinergic and other sedating medications increase the risk for pneumonia).

    AML is an aggressive hematological malignancy with highest incidence in the older adults. The adverse features of AML in the elderly, and the frailties and comorbidities frequently present in them, make their management a particularly difficult therapeutic challenge. In this context, it is important to assess carefully patient- as well as disease-associated prognostic features with validated tools. The fittest patients should be considered for curative therapy, such as bone marrow transplantation, whereas low intensity options may be more appropriate for frail patients. Here we review how to assess patients with elderly AML and the treatments options available for them. PMID:27408788

    Labor-market transitions toward the latter parts of workers’ careers can be complex, with movement between jobs and classes of work and in and out of retirement. The authors analyzed factors associated with the labor-market transitions of older workers to self-employment from unemployment or disability, retirement, or wage and salary work using rich panel data from seven waves of the Health and Retirement Study (HRS). They found evidence that (prior) job characteristics and liquidity constraints are important predictors of movements to self-employment for workers and nonworkers, while risk aversion is a significant predictor only for workers.

    Older people face many difficult challenges that amount to a deplorable violation of their basic human rights (poverty, discrimination, denial of social services, etc.). However, the world has been slow to react. Factors that limit global responses to the challenges of aging include: limited political will, the prevalence of neo-liberalism, and NGOs' longstanding advocacy for other seemingly "more" disadvantaged groups. Such oppression of and discrimination against older people require a concerted world-wide response. We contend that the introduction of an international convention on the human rights of older people is most relevant. Reinforced by a potent international monitoring system, the convention should contain comprehensive and legally binding provisions that require participating states to promote older people's rights. It is argued that international law would be a powerful force in defending and protecting older persons, operating as a baseline for establishing underlying values for national aging policies and linking older persons' concerns with other segments of society.

    Older adults are the fastest growing segment of the world population. Older adults are also at heightened risk of chronic conditions (such as diabetes, heart disease, and cancer) and specific geriatric conditions (such as cognitive impairment, frailty, and falls). Research studies have examined the relationship between fruit and vegetable intake and subsequent health outcomes and the correlates of fruit and vegetable intake in the U.S. population. However, relatively few studies have specifically examined health impacts and correlates of fruit and vegetable intake among older adults, who have unique biophysical and socioeconomic circumstances. Evidence is reviewed to (1) describe findings related to consumption and chronic, geriatric, and other health outcomes among older adults and (2) describe patterns in fruit and vegetable consumption among older adults and how these patterns vary within and among populations. This review addresses specific barriers faced by older adults in obtaining and consuming fruits and vegetables in community settings. Recommendations for practice and policy are discussed.

    The importance of high blood pressure (BP) and the effect of BP lowering in older adults remain controversial due to the mixed evidence in this population. Frailty status may resolve the apparently conflicting findings and identify subpopulations who share common risk. Emerging evidence demonstrates that low BP is associated with poor outcomes in older frail adults or those with poor functional status. In contrast, in non-frail older adults, low BP appears beneficial. Frail older adults may be at increased risk of hypotension, serious fall injuries, and polypharmacy. Additionally, peripheral BP may not be the best prognostic measure in this population. The majority of clinical practice guidelines give little recommendation for frail older adults, which is likely due to their systematic underrepresentation in randomized controlled trials. Future studies need to consider modifications to safely include frail older adults, and guidelines should consider inclusion of evidence beyond randomized controlled trials.

    The extended family used to be relied upon to provide subsistence and care for older people in sub-Saharan Africa. However, recently South Africa has seen a reversal of roles, where older people now provide subsistence and care to younger generations; this role reversal is being accelerated by HIV/AIDS deaths among young adults. In most rural households, the non-contributory old age pension (OAP) that is means-tested is an important factor in making older people breadwinners. Using data from the 2004 Mpumalanga Older People's Survey, we examined the changing role of older people, which has been influenced mainly by changes in household structure and old age pension. Findings show that in 63% of matrifocal, multigenerational households, 76% of older people are the sole providers of household necessities, caring for the sick and grandchildren in increasingly skip-generation households.

    Chemotherapy-related cognitive impairment (CRCI) can occur during or after chemotherapy and represents a concern for many patients with cancer. Among older patients with cancer, in whom there is little clinical trial evidence examining side effects like CRCI, many unanswered questions remain regarding risk for and resulting adverse outcomes from CRCI. Given the rising incidence of cancer with age, CRCI is of particular concern for older patients with cancer who receive treatment. Therefore, research related to CRCI in older patients with cancers is a high priority. In this manuscript, we discuss current gaps in research highlighting the lack of clinical studies of CRCI in older adults, the complex mechanisms of CRCI, and the challenges in measuring cognitive impairment in older patients with cancer. Although we focus on CRCI, we also discuss cognitive impairment related to cancer itself and other treatment modalities. We highlight several research priorities to improve the study of CRCI in older patients with cancer. PMID:27197918

    2012-01-01

    There are a rising number of older adults; in the US alone nearly 20% of the population will be 65 or older by 2030. Chiropractic is one of the most frequently utilized types of complementary and alternative care by older adults, used by an estimated 5% of older adults in the U.S. annually. Chiropractic care involves many different types of interventions, including preventive strategies. This commentary by experts in the field of geriatrics, discusses the evidence for the use of spinal manipulative therapy, acupuncture, nutritional counseling and fall prevention strategies as delivered by doctors of chiropractic. Given the utilization of chiropractic services by the older adult, it is imperative that providers be familiar with the evidence for and the prudent use of different management strategies for older adults.

    Older adults who live alone are at risk for problems (e.g., falling, sudden illness). To maintain themselves safely at home they may benefit from planning to prevent problems. The purpose of this study was to evaluate an intervention designed to train family members or friends as to how to help older adults who were living alone make plans to maintain independence safely in their homes and to make behavioral and household changes to enhance safety. Support network members of 19 older adults randomly assigned to the intervention group were taught to use multiple segment vignettes to assist the older adults in creating plans for living safely. Older adults in the control group (n = 21) were asked to engage in an unstructured discussion about home safety with their network members. Older adults in the intervention group developed safer plans and made more household and behavioral changes than did control group adults.

    Background A fragmented health care system leads to an increased demand for continuity of care across health care levels. Research indicates age-related differences during care transition, with the oldest patients having experiences and needs that differ from those of other patients. To meet the older patients’ needs and preferences during care transition, professionals must understand their experiences. Objective The purpose of the study was to explore how patients ≥80 years of age experienced the care transition from hospital to municipal health care services. Methods The study has a descriptive, explorative design, using semistructured interviews. Fourteen patients aged ≥80 participated in the study. Qualitative content analysis was used to describe the individuals’ experiences during care transition. Results Two complementary themes emerged during the analysis: “Participation depends on being invited to plan the care transition” and “Managing continuity of care represents a complex and challenging process”. Discussion Lack of participation, insufficient information, and vague responsibilities among staff during care transition seemed to limit the continuity of care. The patients are the vulnerable part of the care transition process, although they possess important resources, which illustrate the importance of making their voice heard. Older patients are therefore likely to benefit from more intensive support. A tailored, patient-centered follow-up of each patient is suggested to ensure that patient preferences and continuity of care to adhere to the new situation. PMID:27274204

    The unprecedented growth in the number of older adults in our society is accompanied by the exponential increase in the number of elderly people who will suffer cognitive decline and dementia in the next decades. This will create an enormous cost for governments, families and individuals. Brain plasticity and its role in brain adaptation to the process of aging is influenced by other changes as a result of co-morbidities, environmental factors, personality traits (psychosocial variables) and genetic and epigenetic factors. This review summarizes recent findings obtained mostly from interventional studies that aim to prevent and/or delay age-related cognitive decline in healthy adults. There are a multitude of such studies. In this paper, we focused our review on physical activity, computerized cognitive training and social enhancement interventions on improving cognition, physical health, independent living and wellbeing of older adults. The methodological limitations of some of these studies, and the need for new multi-domain synergistic interventions, based on current advances in neuroscience and social-brain theories, are discussed.

  11. Financial inequality and gender in older people.

    PubMed

    Vlachantoni, Athina

    2012-06-01

    Gender inequalities in the financial resources in later life result from the combined effect of women's atypical life courses, which include interrupted employment records and periods of care provision, and the fact that pension systems have generally been slow in mitigating 'diversions' from continuous and full-time working lives. Gender differentials in financial resources can often result in a greater likelihood of facing poverty for older women compared to older men, and such risk can be experienced for longer periods for women, as a result of their higher life expectancy on average. For example, across the EU-27, 16% of men compared to 23% of women aged 65 and over faced a poverty risk, and at age 65, men can expect to live another 17 years on average, while women another 21 years. Although modern pension systems are increasingly recognising the diversity of women's patterns of paid and unpaid work, for example by accounting for periods of childcare in the calculation of the state pension, research continues to show a 'penalty' for women who have spent significant periods of their life providing care to children or dependent adults in and outside the household. Reducing such penalty is particularly important as population ageing and an increasing demand for formal and informal care are likely to present challenges with critical policy implications for societies and individuals alike.

    Diversity of neighborhood amenities may promote the mobility of older adults. A 2010 community-based sample of 510 adults aged ≥65 years in Philadelphia, Pennsylvania, and geospatial data from the Esri Business Analyst database (Esri, Inc., Redlands, California) were used to assess associations of neighborhood amenity diversity with mobility. Neighborhoods were defined by census tract, and diversity of amenities was derived by using the Leadership in Energy and Environmental Design's neighborhood development index (US Green Building Council, Washington, DC). Generalized estimating equations adjusted for demographic, socioeconomic, and neighborhood characteristics were used to estimate differences in mobility score by tertile of amenity diversity. Analyses were stratified by participants' routine travel habits (stayed at home, stayed in home zip code, or traveled beyond home zip code). We found that for those who spent most of their time in their home neighborhoods, mobility scores (from the Life-Space Assessment, which ranges from 0 to 104 points) were 8.3 points higher (95% confidence interval: 0.1, 16.6) among those who lived in neighborhoods with the most amenity diversity compared with those who lived in neighborhoods with the least amenity diversity. No significant associations between amenity diversity and mobility were observed for those who did not leave home or who regularly traveled outside their neighborhoods. Neighborhoods with a high diversity of amenities may be important promoters of mobility in older adults who do not routinely travel outside their neighborhoods.

    The aim of this study was to compare patterns of cognitive decline in older Latinos and non-Latinos. At annual intervals for a mean of 5.7 years, older Latino (n=104) and non-Latino (n=104) persons of equivalent age, education, and race completed a battery of 17 cognitive tests from which previously established composite measures of episodic memory, semantic memory, working memory, perceptual speed, and visuospatial ability were derived. In analyses adjusted for age, sex, and education, performance declined over time in each cognitive domain, but there were no ethnic group differences in initial level of function or annual rate of decline. There was evidence of retest learning following the baseline evaluation, but neither the magnitude nor duration of the effect was related to Latino ethnicity, and eliminating the first two evaluations, during which much of retest learning occurred, did not affect ethnic group comparisons. Compared to the non-Latino group, the Latino group had more diabetes (38.5% vs. 25.0; χ2[1]=4.4; p=.037), fewer histories of smoking (24.0% vs. 39.4%, χ2[1]=5.7; p=.017), and lower childhood household socioeconomic level (-0.410 vs. -0.045, t[185.0]=3.1; p=.002), but controlling for these factors did not affect results. Trajectories of cognitive aging in different abilities are similar in Latino and non-Latino individuals of equivalent age, education, and race. (JINS, 2016, 22, 58-65).

    The prevalence of diabetes increases with age. In Spain, almost a third of persons older than 75 years have diabetes, and 10% of cases are undiagnosed. The approach in this age group is influenced by the coexistence of comorbidities and geriatric syndromes, as well as by the polypharmacy found in these patients. All the clinical practice guidelines recommend that glycemic control be individually tailored according to such factors as disease duration, the presence of complications, functional status, life expectancy, and the patient's environment, among other elements. In general, the therapeutic approach in older persons does not differ from that recommended in the younger population: it should be multifactorial, considering lifestyle modifications and control of hyperglycemia and the remaining cardiovascular risk factors. The main limitation is hypoglycemia, which is the most common and severe factor in this age group. Therapeutic recommendations in elderly persons with diabetes are based on expert opinion, since these patients are usually excluded from clinical trials. Consequently, clinical judgment is required to optimize the treatment of diabetes, with an emphasis on interventions to prevent symptoms and improve quality of life. DPP-4 inhibitors can be used, due to their low risk of hypoglycemias and safety. Before any treatment is started, its risk/benefit ratio should be evaluated, along with the patient's functional and cognitive status.

    OBJECTIVE To estimate the prevalence of depressive symptoms among institutionalized elderly individuals and to analyze factors associated with this condition. METHODS This was a cross-sectional study involving 462 individuals aged 60 or older, residents in long stay institutions in four Brazilian municipalities. The dependent variable was assessed using the 15-item Geriatric Depression Scale. Poisson’s regression was used to evaluate associations with co-variables. We investigated which variables were most relevant in terms of presence of depressive symptoms within the studied context through factor analysis. RESULTS Prevalence of depressive symptoms was 48.7%. The variables associated with depressive symptoms were: regular/bad/very bad self-rated health; comorbidities; hospitalizations; and lack of friends in the institution. Five components accounted for 49.2% of total variance of the sample: functioning, social support, sensory deficiency, institutionalization and health conditions. In the factor analysis, functionality and social support were the components which explained a large part of observed variance. CONCLUSIONS A high prevalence of depressive symptoms, with significant variation in distribution, was observed. Such results emphasize the importance of health conditions and functioning for institutionalized older individuals developing depression. They also point to the importance of providing opportunities for interaction among institutionalized individuals. PMID:24897042

    2012-04-01

    The amyloidoses are a group of hereditary or acquired disorders caused by the extracellular deposition of insoluble protein fibrils that impair tissue structure and function. All amyloidoses result from protein misfolding, a common mechanism for disorders in older persons, including Alzheimer's disease and Parkinson's disease. Abnormalities in the protein transthyretin (TTR), a serum transporter of thyroxine and retinol, is the most common cause of cardiac amyloidoses in elderly adults. Mutations in TTR can result in familial amyloidotic cardiomyopathy, and wild-type TTR can result in senile cardiac amyloidosis. These underdiagnosed disorders are much more common than previously thought. The resulting restrictive cardiomyopathy can cause congestive heart failure, arrhythmias, and advanced conduction system disease. Although historically difficult to make, the diagnosis of TTR cardiac amyloidosis has become easier in recent years with advances in cardiac imaging and more widespread use of genetic analysis. Although therapy has largely involved supportive medical care, avoidance of potentially toxic agents, and rarely organ transplantation, the near future brings the possibility of targeted pharmacotherapies designed to prevent TTR misfolding and amyloid deposition. Because these disease-modifying agents are designed to prevent disease progression, it has become increasingly important that older persons with TTR amyloidosis be expeditiously identified and considered for enrollment in clinical registries and trials.

    2014-10-01

    Fibromyalgia (FM) is a pain syndrome characterized by dysregulation of pain-processing mechanisms. FM may arise de novo or evolve following nervous system sensitization after an identifiable triggering event or related to a peripheral pain generator such as osteoarthritis. Although the focus symptom of FM is generalized body pain, patients may also experience sleep and mood disturbance, fatigue, and other somatic symptoms leading to the concept of a polysymptomatic condition. In view of prevalent other comorbidities in older patients, FM may be overlooked and management may be neglected, thereby contributing to poor well-being. Pertinent to the older patient is to ensure that the diagnosis of FM is correct and that other conditions are not misdiagnosed as FM. Whereever possible, treatment strategies should emphasize non-pharmacologic interventions that encompass healthy lifestyle habits, with attention to adequate physical activity in particular. Drug treatments should be tailored to the individual needs of the patient, with knowledge that they may offer only a modest effect, but with caution to ensure that adverse effects do not overshadow therapeutic effects.

    2016-01-01

    Glioblastoma, a WHO grade IV astrocytoma, is the most common primary malignant brain tumor in adults. It is characterized by molecular heterogeneity and aggressive behavior. Glioblastoma is almost always incurable and most older patients survive less than 6 months. Supportive care with steroids and anti-epileptic drugs is critical to improving and maintain quality of life. Young age, good performance status and methylation of the methyl guanyl methyl transferase promoter are important positive prognostic factors. Several recent clinical trials suggest that there is a subset of the elderly with prolonged survival that is comparable to younger patients. Treatment of glioblastoma in older patients includes maximal safe resection followed by either radiation, chemotherapy or combined modality therapy. Recent advances suggest that some patients can avoid radiation entirely and be treated with chemotherapy alone. Decisions about therapy are individual and based on a patient's performance status, family support and molecular features. Future work needs to better determine the role for comprehensive geriatric assessments in this patient population to better identify patients who may most benefit from aggressive therapies.

    2008-07-01

    The size and impending morbidity of the aging baby boom generation could soon overwhelm the U.S. health care system. Transforming chronic care for older persons to avert this calamity will require rapid increases in the number of physicians who are skilled in providing chronic care and prompt adoption of new models for providing high-quality, cost-effective chronic care. The authors propose a new approach for attaining these objectives, recommending that today's leaders of academic medicine help transform geriatrics into a collaborative discipline of clinicians with advanced skills in leading educational, organizational, and research-related initiatives; that they support the collaboration of geriatrics with primary care and specialty disciplines in preparing physicians to practice effectively in new models of chronic care for older persons; and that they energetically promote rigorous training in chronic care at all levels of medical education. Implementing this strategy would require firm commitment by the Association of American Medical Colleges, specialty boards, accrediting organizations, academic institutions, the Centers for Medicare and Medicaid Services, legislators, and business leaders. Although garnering such support would be challenging and controversial, this approach could leverage the expertise of geriatric educator-leaders to help transform chronic care in the United States and to make high-quality, cost-effective chronic care accessible to most chronically ill Americans within 20 years.

    In 2 experiments we examined the influence of frontal lobe function on older adults' susceptibility to false memory in a categorized list paradigm. Using a neuropsychological battery of tests developed by Glisky, Polster, and Routhieaux (1995), we designated older adults as having high- or low-frontal function. Young and older adults studied and were tested on categorized lists using free report cued recall and forced report cued recall instructions, with the latter requiring participants to produce responses even if they had to guess. Under free report cued recall instructions, frontal lobe function was a strong predictor of false memories in older adults: Older adults who scored low on tests of frontal functioning demonstrated much higher levels of false recall than younger adults, whereas levels of false recall in high-frontal older adults were more similar to those of young adults. However, after forced report cued recall, high- and low-frontal older adults performed similarly to each other, and both demonstrated higher levels of false recall than young adults. On a final recognition test, high-frontal older adults in both the free report cued recall and forced report cued recall conditions were more successful than low-frontal older adults in using source information to reduce memory errors. The results indicate that older adults show higher levels of false recall than younger adults, but type of test (free report or forced report) and neuropsychological status of older adults mediate these effects. Low-frontal older adults are particularly susceptible to producing false memories on free report tests that entail source monitoring. PMID:23350303

    Older adults constitute the group with the greatest increase in Internet usage in the past decade; however, usage varies greatly within this population. Services to older adults require a current understanding of Internet-use trends. This study utilized a quantitative survey method to examine correlates of, and barriers to, current Internet use in a demographically diverse county in Southern California. Findings indicate that the presence of a computer at home, a job requiring computer use, age, education, and ethnicity are important factors in predicting Internet use in older adults. Implications for social work practice with older adults is discussed.

    Pain is a physical, emotional and psychologic phenomenon that is often ignored in older adults causing depression and poor quality of life. Older adults report the use of complementary and alternative medicine in some form with 80% of these users reporting improvement in their health conditions. Although physical pain in the older adult is usually managed with pharmacologic interventions, methods that may reduce the use of prescription drugs may decrease adverse effects that can compromise the physiologic state of the older adult. Hypnosis has continued to gain acceptance within mainstream medicine as an appropriate treatment and can be integrated safely with conventional medicine as an effective treatment for a variety of conditions in the older adult. It is an intervention that can be used for relaxation and pain control, especially when conventional pharmacologic regimens have failed. The purpose of this article is to review the concepts related to pain in older adults; the use of complementary and alternative medicine in the older adult; hypnosis and the older adult (i.e., background, definition, benefits, research, mechanism of action, hypnotizability, and the process); and the implications of using hypnosis for pain management in the older adult.

    Sepsis in older adults has many challenges that affect rate of septic diagnosis, treatment, and monitoring parameters. Numerous age-related changes and comorbidities contribute to increased risk of infections in older adults, but also atypical symptomatology that delays diagnosis. Due to various pharmacokinetic/pharmacodynamic changes in the older adult, medications are absorbed, metabolized, and eliminated at different rates as compared to younger adults, which increases risk of adverse drug reactions due to use of drug therapy needed for sepsis management. This review provides information to aid in diagnosis and offers recommendations for monitoring and treating sepsis in the older adult population.

    Older lesbian, gay, bisexual, and transgender (LGBT) adults face unique issues that can impede their well-being. Although many advances have helped address these issues, there is a need for education efforts that raise awareness of service providers about these issues. This study explores evaluation data of training panels provided by older LGBT adults and the views of training participants on issues faced by the older LGBT community after attending the panels. Participants were 605 students and professionals from over 34 education and communication settings. Implications for trainings on participants and older LGBT trainers are discussed.

    The dependency between the risk of death and age is analysed, and the contribution of cancer to the overall risk of death is evaluated as a function of age. The frequency of the different cancer sites is described in different age groups. Lastly cancer mortality trends are presented by age. The risk of death from cancer increases markedly with age, but the risk of a death from a cardiovascular disease increases even more rapidly, consequently the importance of cancer as a cause of death decreases with age. In the male population, lung and head and neck cancers are the most frequent cancers before age 65, whereas prostate and colorectal cancers are more frequent at older ages. In the female population, breast and colorectal cancers are the most frequent cancers except for mortality before age 65 where lung cancer is the second killer after breast cancer. The risk of cancer death decreases in recent years for all age groups.

    Abstract Purpose: In Boston and Outer Cape, Massachusetts, we explored the expectations of lesbians 60 years and older regarding healthy aging and community importance. Methods: Focus groups were conducted with participants after completing an anonymous demographic questionnaire. Thematic analysis was used to generate themes and identify how they varied by urban versus rural settings. Results: Group discussions focused on community, finances, housing, and healthcare. Primary concerns included continued access to supportive and lesbian communities as a source of resilience during aging. Conclusion: Concerns about discrimination and isolation mirror themes found in national research. The study findings suggest a need for more research into the housing and transportation needs of lesbians approaching later life, with a focus on how those needs relate to affordability, accessibility, and proximity to social support and healthcare. These findings also suggest the need for substantial investments in strengthening the LGBT-related cultural competence of providers of services for the elderly. PMID:27046541

  14. Additional potential for older, Antrim Shale wells

    The Gas Research Institute (GRI) has been performing evaluations to estimate the recompletion and restimulation potential in older, Antrim Shale wells. The recompletion potential is two-fold: (1) wells that can be deepened to the productive Norwood interval, and (2) wells with Upper Antrim potential. There are also numerous restimulation candidates due to sand flowback and/or other problems. The Antrim Shale is an organic-rich naturally fractured formation which produces both gas and water. Operators today typically complete the Lachine and Norwood intervals but many older wells were not drilled deep enough to encounter to Norwood. We performed an evaluation to determine the optimal deepening method using actual and simulated data. We estimate there are over 500 deepening candidates with total potential reserve additions of 50 Bscf. The Upper antrim formation can be added in approximately 1,500 existing wells throughout several counties. This interval is uphole from the Lachine and Norwood. In this phase of the project, we collected production and reservoir data from several Upper Antrim tests across the basin. We estimate the Upper Antrim could add total new reserves of 100 to 200 Bscf from al the recompletion candidates across the basin. In the restimulation evaluation, we developed a novel injection test unit to help operators identify the best restimulation candidates in a cost effective manner. The injection test determines if an effective hydraulic fracture is connected to the wellbore. Based on 60 test wells, we estimate the restimulations could add 50 to 200 Bscf of future reserves from the 500 to 1,000 candidate wells.

    Previous tests of the SeniorWISE intervention with community-residing older adults that were designed to improve affect and cognitive performance were successful and positively affected these outcomes. In this study, we tested whether adding yoga to the intervention would affect the outcomes. Using a quasiexperimental pre-post design, we delivered 12 hours of SeniorWISE memory training that included a 30-minute yoga component before each training session. The intervention was based on the four components of self-efficacy theory: enactive mastery experience, vicarious experience, verbal persuasion, and physiologic arousal. We recruited 133 older adults between the ages of 53 and 96 years from four retirement communities in Central Texas. Individuals were screened and tested and then attended training sessions two times a week over 4 weeks. A septuagenarian licensed psychologist taught the memory training, and a certified yoga instructor taught yoga. Eighty-three participants completed at least 9 hours (75%) of the training and completed the posttest. Those individuals who completed made significant gains in memory performance, instrumental activities of daily living, and memory self-efficacy and had fewer depressive symptoms. Thirteen individuals advanced from poor to normal memory performance, and seven improved from impaired to poor memory performance; thus, 20 individuals improved enough to advance to a higher functioning memory group. The findings from this study of a memory training intervention plus yoga training show that the benefits of multifactorial interventions had additive benefits. The combined treatments offer a unique model for brain health programs and the promotion of nonpharmacological treatment with the goals of maintaining healthy brain function and boosting brain plasticity.

  16. Carotenoids and health in older people.

    2015-01-01

    As the proportion of older people increases, so will chronic disease incidence and the proportion of the population living with disability. Therefore, new approaches to maintain health for as long as possible in this age group are required. Carotenoids are a group of polyphenolic compounds found predominantly in fruit and vegetables that have been proposed to have anti-inflammatory and antioxidant effects. Such properties may impact on the risk diseases which predominate in older people, and also ageing-related physiological changes. Working out the effect of carotenoid intake versus fruit and vegetable intake is difficult, and the strong correlation between individual carotenoid intakes also complicates any attempt to examine individual carotenoid health effects. Similarly, research to determine whether carotenoids consumed as supplements have similar benefits to increased dietary intake through whole foods, is still required. However, reviewing the recent evidence suggests that carotenoid intake and status are relatively consistently associated with reduced CVD risk, although β-carotene supplementation does not reduce CVD risk and increases lung cancer risk. Increased lycopene intake may reduce prostate cancer progression, with a potential role for carotenoids at other cancer sites. Lutein and zeaxanthin have a plausible role in the maintenance of eye health, whilst an association between carotenoid intake and cognitive and physical health appears possible, although research is limited to date. Given this accruing evidence base to support a specific role for certain carotenoids and ageing, current dietary advice to consume a diet rich in fruit and vegetables would appear prudent, and efforts maintained to encourage increased intake.

    Various clinical studies throughout the years have shown that individuals with ostomies are a unique group facing adjustment demands. One of the most important challenges for an individual with an ostomy is coping with the physiological and psychological changes. The purpose of this study was to describe coping styles of older adults after undergoing ostomy surgery and to explore its helpfulness in dealing with the stressors related to having an ostomy. Lazarus and Folkman's theory on stress and coping was used as the framework to guide this study. A sample of 27 participants ranging from age 50 to 84 years was obtained from an ostomy association in southeastern Louisiana. Participants were asked to complete a demographic data form and the Revised Jalowiec Coping Scale. This revised scale measured eight coping styles related to Use and Effectiveness. Findings revealed significant differences existed among the means of the eight measures for both Use and Effectiveness at p < .01. Results demonstrated that the optimistic and self-reliant styles of coping were the most frequently used as effective styles for coping with an ostomy. This indicated a positive outlook and dependence on oneself rather than dependence on others when coping with the stressors of having an ostomy. There were no statistically significant differences related to gender or ostomy type. Also, aging did not appear to be a factor when considering coping styles of older adults with ostomies. The nursing role should include assessment of the individual preoperatively to identify fears, concerns, and stressors related to having an ostomy. Also, nurses can provide education on disease management, assist with identification of ineffective coping mechanisms, and promote effective coping skills and stress management techniques.

    Purpose Anisometropia shows an exponential increase in prevalence with increasing age based on cross-sectional studies. The purpose of this study was to evaluate longitudinal changes in anisometropia in all refractive components in older observers and to assess the influence of early cataract development. Methods Refractive error was assessed at two time points separated by ~12 years in 118 older observers (ages 67.1 and 79.3 years at the two test times). Anisometropia defined as ≥1.00 D was calculated for all refractive components. The subjects had intact ocular lenses in both eyes throughout the study. Lens evaluations were performed at the second test using LOCS III. Results All refractive components approximately doubled in prevalence of anisometropia. Spherical equivalent anisometropia changed from 16.1% to 32.2%. Similar changes were found for spherical error (17% to 38.1%), primary astigmatism (7.6% to 17.8%) and oblique astigmatism (14.4% to 29.7%). Many who did not have anisometropia at the first visit subsequently developed anisometropia (for ex. 26.3% for spherical error and 22.9% for oblique cylinder). The onset of anisometropia occurred at all ages within the studied age range with no particular preference for any one age. A small number lost anisometropia over time. Individual comparisons of refractive error changes in the two eyes in combination with nuclear lens changes showed that early changes in nuclear sclerosis in the two eyes could account for a large proportion of anisometropia (~40%) but unequal hyperopic shift in the spherical component in the two eyes was the primary cause of the anisometropia. Conclusions Anisometropia is at least 10 times more common in the elderly than in children and anisometropia develops in all refractive components in the oldest observers. Clinicians need to be aware of this common condition that could lead to binocular vision problems and potentially cause falls in the elderly. PMID:24276578

    Rehabilitation is a key component of nursing and allied healthcare professionals' roles in most health and social care settings. This paper reports on stage 2 of an action research project to ascertain older adult's experience of rehabilitation. Twenty postdischarge interviews were conducted and the interview transcripts were analysed using thematic content analysis. All older adults discharged from an acute older acute rehabilitation ward to their own homes in the community were eligible to participate. The only exclusion criterion was older adults who were thought to be unable to give consent to participate by the nurse in charge and the researcher. Whilst 92 older adults were eligible to participate in this research study, only 20 were interviewed. The findings from this study suggest that older adults valued communication with health professionals but were aware of their time constraints that hindered communication. This study suggests that both nurses and allied health professionals are not actively providing rehabilitative services to promote health and well-being, which contradicts the focus of active ageing. Furthermore, there was evidence of unmet needs on discharge, and older adults unable to recall the professions that were involved in their interventions and the rationale for therapy input. It is suggested that further research is needed to explore the effectiveness of allied health rehabilitation in the acute setting. This study highlights the need for further research into older adults' perceptions of the rehabilitation process in the acute setting.
