    Jong Hwan Kim


    Full Text Available Background Infection caused by rapidly growing mycobacteria (RGM is not uncommon, andthe prevalence of RGM infection has been increasing. Clinical diagnosis is difficult becausethere are no characteristic clinical features. There is also no standard antibiotic regimenfor treating RGM infection. A small series of patients with RGM infections was studied toexamine their treatments and outcomes.Methods A total of 5 patients who had developed postoperative infections from January2009 to December 2010 were retrospectively reviewed. Patients were initially screened using amycobacteria rapid screening test (polymerase chain reaction [PCR]-reverse blot hybridizationassay. To confirm mycobacterial infection, specimens were cultured for nontuberculousmycobacteria and analyzed by 16 S ribosomal RNA and rpoB gene PCR.Results The patients were treated with intravenous antibiotics during hospitalization,and oral antibiotics were administered after discharge. The mean duration of follow-upwas 9 months, and all patients were completely cured of infection with a regimen of acombination of antibiotics plus surgical treatment. Although none of the patients developedrecurrence, there were complications at the site of infection, including hypertrophic scarring,pigmentation, and disfigurement.Conclusions Combination antibiotic therapy plus drainage of surgical abscesses appeared tobe effective for the RGM infections seen in our patients. Although neither the exact dosagenor a standardized regimen has been firmly established, we propose that our treatment canprovide an option for the management of rapidly growing mycobacterial infection.

  3. A Female Therapist's Perspective on Growing Older. (United States)

    Fodor, Iris


    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. © 2015 Wiley Periodicals, Inc.

  6. Growing older with post-traumatic stress disorder. (United States)

    Curran, B; Collier, E


    WHAT IS KNOWN ON THE SUBJECT?: The needs of older people with long-term mental illness are not very well addressed in policy and research. Older people are not a homogenous group and people ageing with long-term mental illness have potentially unique or specific needs. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: A unique example of the idiosyncratic and contextual nature of individual strengths and the abilities in managing personal recovery when experiencing long-term mental illness. Emotional exhaustion experienced after long-term mental health compromises the ability to manage feelings, potentially a special feature of life time mental ill health. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Recognition that the hard work involved in successfully managing long-term personal recovery may be important in preventing suicide in later life. The need to understand a person's life story to make sense of their experience of mental illness and to recognize long-term mental illness to later life as part of a persons' established identity. The importance of appreciating the place of early memories for understanding older person's mental health in their present. Introduction Ageing with mental illness is a neglected area of research and policy. People who grow older to later life with ongoing mental health problems may not have their needs well understood. This understanding is important if mental health services are to ensure direct or indirect age discrimination is avoided. Aim This paper aims to explore issues relating to later life and ageing with mental illness focused on the story of Bernard (who was 84 years of age at the time of writing) who lived with a diagnosis of post-traumatic stress disorder (PTSD). Method The paper is co-authored by Bernard and the researcher he originally told his story to as a participant in a biographical research study exploring mental ill health through the life course. In the original research study, Bernard completed a curriculum vitae

  7. Environmental and Social Programmes and Rapidly Growing Retailers

    Directory of Open Access Journals (Sweden)

    Peter JONES


    Full Text Available This paper looks to provide an exploratory review of the extent to which the world’s fastest growing retailers are publicly reporting on their environmental and social commitments and programmes. The paper begins with an outline discussion of corporate environmental and social programmes and on public reporting processes. The paper draws its empirical material from the most recent information on environmental and social commitments and programmes posted on the world’s top twenty fastest growing retailers’ corporate web sites. While the majority of the world’s top twenty fastest growing retailers provide some public information on their commitment to environmental and social programmes there is marked variation in the extent, the nature and the detail of that information. The findings suggest that the integration of environmental and social programmes is not one of the hallmarks of rapidly growing retailers and in part this reflects the fact that many of the selected retailers are trading within emergent markets where price and availability are the principal factors driving consumer buying behaviour.

  8. Biomass accumulation in rapidly growing loblolly pine and sweetgum

    Williams, Thomas M.; Gresham, Charles A. [Baruch Institute of Coastal Ecology and Forest Science, Clemson University, P.O. Box 596, Georgetown, SC 29442 (United States)


    Loblolly pine (Pinus taeda) and sweetgum (Liquidambar styraciflua) trees, growing in International Paper Company's study of intensive management on marginal agricultural land near Bainbridge GA, were destructively sampled at the end of the sixth growing season. All trees were single family blocks of genetically superior trees planted 2.5m apart on sub-soiled rows 3.6m apart and grown with complete competition control. Management treatments were: control, irrigation, irrigation plus fertilization, and irrigation plus fertilization plus pest control. Tree measures were basal diameter, DBH, height of live crown, diameter at base of live crown, and total height. Twenty trees of each species were destructively sampled. Stems were sectioned at 1m intervals, stem diameter determined at each end and sections were weighed green. Branches were removed and height, basal diameter, and length were measured on each branch. Branches were separated into foliated and unfoliated segments and weighed green. A stem disk and branch from each meter were returned to the lab to determine dry weight: green weight ratio. Foliated limb: foliage ratios were also determined from sub-sampled branches. Intensive culture resulted in larger growth differences for sweetgum (most intensive treatment 9.5m tall, 13.1cm DBH; control trees 5.0m tall, 6.3cm DBH) than in pine (most intensive treatment 10.3m tall, 17.7cm DBH; control, 7.6m tall, 13.4cm DBH). The pipe model of tree development explained dimensions of the upper 5m of crown with leaf biomass highly correlated to branch basal area (r{sup 2} from 0.697 to 0.947). There was a constant ratio of leaf biomass to branch basal area (50gm/cm{sup 2} for pine, 30gm/cm{sup 2} for sweetgum). We also found a constant ratio of bole basal area to cumulative branch basal area throughout the crowns. Rapidly growing pines produced about 49Mgha{sup -1} of stem biomass, 11Mgha{sup -1} of dead branch biomass, and 17Mgha{sup -1} of unfoliated branch biomass at

  9. Rapidly Growing Esophageal Carcinosarcoma Reduced by Neoadjuvant Radiotherapy Alone

    Full Text Available Esophageal carcinosarcoma is a rare malignant neoplasm consisting of both carcinomatous and sarcomatous components. It is generally treated by surgery, radiotherapy and chemotherapy according to the protocols used for other esophageal cancers. However, the treatment of esophageal carcinosarcoma by radiotherapy alone before surgery has not been previously described. We report a patient with a rapidly growing esophageal carcinosarcoma that was efficiently reduced by neoadjuvant radiotherapy alone. A previously healthy 69-year-old man was admitted with dysphagia. Initial esophagogastroduodenoscopy (EGD revealed a small nodular polypoid lesion of about 10 mm in the middle esophagus. A second EGD 1 month later showed that the tumor had expanded into a huge mass. A biopsy specimen revealed that the tumor comprised squamous cell carcinoma with spindle cell components, and the tumor was diagnosed as carcinosarcoma which was diagnosed as stage I (T1bN0M0. Due to renal dysfunction, the patient was treated with neoadjuvant radiotherapy (40 Gy without chemotherapy. A third EGD 1 month later revealed remarkable tumor reduction. He then underwent total esophagectomy with regional lymph node dissection (pStage 0, pT1aN0M0. After surgical operation, the patient was followed up without adjuvant therapy. Whole body computed tomography revealed lung metastasis 14 months after surgery, and the patient died 2 months later. The neoadjuvant radiotherapy for esophageal carcinosarcoma was considered to have contributed to the subsequent surgery and his prolonged survival time. Thus, radiotherapy alone might be a suitable neoadjuvant therapy for esophageal carcinosarcomas.

  10. Financial capacity in older adults: a growing concern for clinicians. (United States)

    Gardiner, Paul A; Byrne, Gerard J; Mitchell, Leander K; Pachana, Nancy A


    Older people with cognitive impairment and/or dementia may be particularly vulnerable to diminished financial decision-making capacity. Financial capacity refers to the ability to satisfactorily manage one's financial affairs in a manner consistent with personal self-interest and values. Impairment of financial capacity makes the older individual vulnerable to financial exploitation, may negatively affect their family's financial situation and places strain on relationships within the family. Clinicians are often on the front line of responding to queries regarding decision-making capacity, and clinical evaluation options are often not well understood. Assessment of financial capacity should include formal objective assessment in addition to a clinical interview and gathering contextual data. Development of a flexible, empirically supported and clinically relevant assessment approach that spans all dimensions of financial capacity yet is simple enough to be used by non-specialist clinicians is needed.

  11. Nutrition Considerations for the Growing Population of Older Adults With Diabetes


    Stanley, Kathleen


    The growing older adult population and its higher incidence of diabetes are creating demands on health care providers to address the special needs of these patients. Because nutrition is essential to the proper treatment and self-management of diabetes, clinicians must develop and adopt various strategies to address some of the common nutritional, lifestyle, and self-management barriers that older adults face. Nutrition assessments of older adults with diabetes should be comprehensive, with a...

  12. Intraoral tumor with rapid growing. Report of a case. (United States)

    González-Martín-Moro, Javier; Cebrián-Carretero, Jose Luis; Gómez-García, Elena; del Castillo-Pardo de Vera, Jose Luis; del Val, Daniel


    The appearance of an intraoral mass is common in our specialty. Most are benign lesions, but some are primary malignancies. Metastases account for less than 1% of all oral malignancies. An 86 year old woman was referred to our department with a large, asymptomatic, intraoral, fast-growing mass. She had no previous cancer history or other relevant physical findings. The radiology studies showed underlying bone erosion. The histological study showed a metastatic adenocarcinoma with a suspected origin in the abdomen. We were unable to identify it by non invasive diagnostic procedures. Given the patient's general status and despite the ominous prognosis of such lesions, we decided not to perform any aggressive therapy beyond removing the oral mass, in order to maintain her quality of life. There have been no local recurrences until this time.

  13. Naturalistic rapid deceleration data: Drivers aged 75 years and older

    Anna Chevalier


    Full Text Available The data presented in this article are related to the research manuscript “Predictors of older drivers’ involvement in rapid deceleration events”, which investigates potential predictors of older drivers’ involvement in rapid deceleration events including measures of vision, cognitive function and driving confidence (A. Chevalier et al., 2016 [1]. In naturalistic driving studies such as this, when sample size is not large enough to allow crashes to be used to investigate driver safety, rapid deceleration events may be used as a surrogate safety measure. Naturalistic driving data were collected for up to 52 weeks from 182 volunteer drivers aged 75–94 years (median 80 years, 52% male living in the suburban outskirts of Sydney. Driving data were collected using an in-vehicle monitoring device. Accelerometer data were recorded 32 times per second and Global Positioning System (GPS data each second. To measure rapid deceleration behavior, rapid deceleration events (RDEs were defined as having at least one data point at or above the deceleration threshold of 750 milli-g (7.35 m/s2. All events were constrained to a maximum 5 s duration. The dataset provided with this article contains 473 events, with a row per RDE. This article also contains information about data processing, treatment and quality control. The methods and data presented here may assist with planning and analysis of future studies into rapid deceleration behaviour using in-vehicle monitoring.

  14. Growing Use of Mental and General Health Care Services Among Older Veterans With Mental Illness. (United States)

    Wiechers, Ilse R; Karel, Michele J; Hoff, Rani; Karlin, Bradley E


    National data from Veterans Health Administration (VHA) electronic medical records were used to examine rates of mental illness and service use among older veterans since mental health care transformation efforts were implemented in 2005. Data were extracted from VHA electronic medical records for each fiscal year from 2005 through 2013 for veterans ages 65 and older. Among those receiving any health care services, the number and proportion treated for a confirmed mental illness and the utilization of non-mental health care services were identified. In 2013, 2.6 million older veterans utilized services in VHA, 14% of whom had a confirmed mental illness, which was a 57% increase from 2005. Older veterans with confirmed mental illness accounted for a sizable and growing proportion of non-mental health service utilization. Preparing the workforce to address the mental health needs of older veterans and nonveterans is essential.

  16. Evaluation of Various Culture Media for Detection of Rapidly Growing Mycobacteria from Patients with Cystic Fibrosis. (United States)

    Preece, Clair L; Wichelhaus, Thomas A; Perry, Audrey; Jones, Amanda L; Cummings, Stephen P; Perry, John D; Hogardt, Michael


    Isolation of nontuberculous mycobacteria (NTM) from the sputum of patients with cystic fibrosis (CF) is challenging due to overgrowth by rapidly growing species that colonize the lungs of patients with CF. Extended incubation on Burkholderia cepacia selective agar (BCSA) has been recommended as an expedient culture method for the isolation of rapidly growing NTM in this setting. The aim of this study was to assess five selective media designed for the isolation of Burkholderia cepacia complex, along with two media designed for the isolation of mycobacteria (rapidly growing mycobacteria [RGM] medium and Middlebrook 7H11 agar), for their abilities to isolate NTM. All seven media were challenged with 147 isolates of rapidly growing mycobacteria and 185 isolates belonging to other species. RGM medium was then compared with the most selective brand of BCSA for the isolation of NTM from 224 sputum samples from patients with CF. Different agars designed for the isolation of B. cepacia complex varied considerably in their inhibition of other bacteria and fungi. RGM medium supported the growth of all isolates of mycobacteria and was more selective than any other medium. NTM were recovered from 17 of 224 sputum samples using RGM medium, compared with only 7 samples using the most selective brand of BCSA (P = 0.023). RGM medium offers a superior option, compared to other selective agars, for the isolation of rapidly growing mycobacteria from the sputum of patients with CF. Furthermore, the convenience of using RGM medium enables routine screening for rapidly growing NTM in all submitted sputum samples from patients with CF.

  19. Mycobacterium aquiterrae sp. nov., a rapidly growing bacterium isolated from groundwater. (United States)

    Lee, Jae-Chan; Whang, Kyung-Sook


    A strain representing a rapidly growing, Gram-stain-positive, aerobic, rod-shaped, non-motile, non-sporulating and non-pigmented species of the genus Mycobacterium, designated strain S-I-6T, was isolated from groundwater at Daejeon in Korea. The strain grew at temperatures between 10 and 37 °C (optimal growth at 25 °C), between pH 4.0 and 9.0 (optimal growth at pH 7.0) and at salinities of 0-5 % (w/v) NaCl, growing optimally with 2 % (w/v) NaCl. Phylogenetic analyses based on multilocus sequence analysis of the 16S rRNAgene, hsp65, rpoB and the 16S-23S internal transcribed spacer indicated that strain S-I-6T belonged to the rapidly growing mycobacteria, being most closely related to Mycobacterium sphagni. On the basis of polyphasic taxonomic analysis, the bacterial strain was distinguished from its phylogenetic neighbours by chemotaxonomic properties and other biochemical characteristics. DNA-DNA relatedness among strain S-I-6T and the closest phylogenetic neighbour strongly support the proposal that this strain represents a novel species within the genus Mycobacterium, for which the name Mycobacterium aquiterrae sp. nov. is proposed. The type strain is S-I-6T (=KACC 17600T=NBRC 109805T=NCAIM B 02535T).

    Set R


    Full Text Available Purpose: The objective of the study was to perform antimicrobial susceptibility testing of rapidly growing mycobacteria (RGM isolated from various clinically suspected cases of extrapulmonary tuberculosis, from January 2007 to April 2008, at a tertiary care centre in Mumbai. Materials and Methods: The specimens were processed for microscopy and culture using the standard procedures. Minimum inhibitory concentrations (MIC were determined by broth microdilution, using Sensititre CA MHBT. Susceptibility testing was also carried out on Mueller Hinton agar by the Kirby Bauer disc diffusion method. Results: Of the 1062 specimens received for mycobacterial cultures, 104 (9.79% grew mycobacteria. Of the mycobacterial isolates, six (5.76% were rapid growers. M. abscessus and M. chelonae appeared to be resistant organisms, with M. chelonae showing intermediate resistance to amikacin and minocycline. However, all the six isolates showed sensitivity to vancomycin and gentamicin by the disc diffusion test. Also all three isolates of M. abscessus were sensitive to piperacillin and erythromycin. Further studies are required to test their sensitivity to these four antimicrobials by using the microbroth dilution test, before they can be prescribed to patients. Conclusions: We wish to emphasize that reporting of rapidly growing mycobacteria from clinical settings, along with their sensitivity patterns, is an absolute need of the hour.

  1. Aging With Rising Risk: Have Older Households Experienced Faster-Growing Risk Exposure Than Younger Ones Since the 1990s? (United States)

    Weller, Christian; Bernardo, Sara


    Financial markets have been characterized by boom and bust cycles since the 1980s, while the responsibility for managing retirement wealth has increasingly shifted onto individual households at the same time. Policy makers and experts have expressed concern over rising risk exposure among older householders, who appear to be increasingly exposed to the growing financial risks just as they near retirement. We consider household data from the Federal Reserve's Survey of Consumer Finances from 1989 to 2010 to analyze the correlation between age and risk exposure. We test whether older householders' risk exposure has indeed grown over time, whether it has increased more than that of younger householders, whether changes in the demographic composition of older householders have contributed to older households' rising risk exposure, and the degree to which increases in risk exposure can be traced to a growing concentration of household assets held in stocks and housing and to rising householder indebtedness. Our results indicate that risk exposure has grown more for older householders than for younger ones, that demographic changes among older householders have contributed to additional increases in older householders' risk exposure, and that the growth of older householders' risk exposure is driven more by rising risky asset concentration and less by greater indebtedness.

  2. Clinical management of rapidly growing mycobacterial cutaneous infections in patients after mesotherapy. (United States)

    Regnier, Stéphanie; Cambau, Emmanuelle; Meningaud, Jean-Paul; Guihot, Amelie; Deforges, Lionel; Carbonne, Anne; Bricaire, François; Caumes, Eric


    Increasing numbers of patients are expressing an interest in mesotherapy as a method of reducing body fat. Cutaneous infections due to rapidly growing mycobacteria are a common complication of such procedures. We followed up patients who had developed cutaneous infections after undergoing mesotherapy during the period October 2006-January 2007. Sixteen patients were infected after mesotherapy injections performed by the same physician. All patients presented with painful, erythematous, draining subcutaneous nodules at the injection sites. All patients were treated with surgical drainage. Microbiological examination was performed on specimens that were obtained before and during the surgical procedure. Direct examination of skin smears demonstrated acid-fast bacilli in 25% of the specimens that were obtained before the procedure and 37% of the specimens obtained during the procedure; culture results were positive in 75% of the patients. Mycobacterium chelonae was identified in 11 patients, and Mycobacterium frederiksbergense was identified in 2 patients. Fourteen patients were treated with antibiotics, 6 received triple therapy as first-line treatment (tigecycline, tobramycin, and clarithromycin), and 8 received dual therapy (clarithromycin and ciprofloxacin). The mean duration of treatment was 14 weeks (range, 1-24 weeks). All of the patients except 1 were fully recovered 2 years after the onset of infection, with the mean time to healing estimated at 6.2 months (range, 1-15 months). This series of rapidly growing mycobacterial cutaneous infections highlights the difficulties in treating such infections and suggests that in vitro susceptibility to antibiotics does not accurately predict their clinical efficacy.

  3. Rapid urbanization and the growing threat of violence and conflict: a 21st century crisis. (United States)

    Patel, Ronak B; Burkle, Frederick M


    As the global population is concentrated into complex environments, rapid urbanization increases the threat of conflict and insecurity. Many fast-growing cities create conditions of significant disparities in standards of living, which set up a natural environment for conflict over resources. As urban slums become a haven for criminal elements, youth gangs, and the arms trade, they also create insecurity for much of the population. Specific populations, such as women, migrants, and refugees, bear the brunt of this lack of security, with significant impacts on their livelihoods, health, and access to basic services. This lack of security and violence also has great costs to the general population, both economic and social. Cities have increasingly become the battlefield of recent conflicts as they serve as the seats of power and gateways to resources. International agencies, non-governmental organizations, and policy-makers must act to stem this tide of growing urban insecurity. Protecting urban populations and preventing future conflict will require better urban planning, investment in livelihood programs for youth, cooperation with local communities, enhanced policing, and strengthening the capacity of judicial systems.

  4. Cancer survivors in Switzerland: a rapidly growing population to care for (United States)


    Background Cancer survivors are a heterogeneous group with complex health problems. Data concerning its total number and growing dynamics for Switzerland are scarce and outdated. Methods Population and mortality data were retrieved from the Swiss Federal Statistical Office (FSO). Incidence and relative survival for invasive cancers were computed using data from the cancer registries Geneva (1970–2009), St. Gallen - Appenzell (1980–2010), Grisons & Glarus (1989–2010), and Valais (1989–2010). We estimated prevalence for 1990–2010 using the Prevalence, Incidence Approach MODel (PIAMOD) method. We calculated trends in prevalence estimates by Joinpoint analysis. Projections were extrapolated using the above models and based on time trends of the period 2007–2010. Results The estimated number of cancer survivors increased from 139′717 in 1990 (2.08% of the population) to 289′797 persons in 2010 (3.70%). The growth rate shows an exponential shape and was 3.3% per year in the period 2008 to 2010. Almost half of the survivors have a history of breast, prostate or colorectal cancer. Among cancer survivors, 55% are women but the increases have been more marked in men (p Switzerland. Conclusions There is a rapidly growing population of cancer survivors in Switzerland whose needs and concerns are largely unknown. PMID:23764068

  5. Aquaculture: a rapidly growing and significant source of sustainable food? Status, transitions and potential. (United States)

    Little, D C; Newton, R W; Beveridge, M C M


    The status and potential of aquaculture is considered as part of a broader food landscape of wild aquatic and terrestrial food sources. The rationale and resource base required for the development of aquaculture are considered in the context of broader societal development, cultural preferences and human needs. Attention is drawn to the uneven development and current importance of aquaculture globally as well as its considerable heterogeneity of form and function compared with established terrestrial livestock production. The recent drivers of growth in demand and production are examined and the persistent linkages between exploitation of wild stocks, full life cycle culture and the various intermediate forms explored. An emergent trend for sourcing aquaculture feeds from alternatives to marine ingredients is described and the implications for the sector with rapidly growing feed needs discussed. The rise of non-conventional and innovative feed ingredients, often shared with terrestrial livestock, are considered, including aquaculture itself becoming a major source of marine ingredients. The implications for the continued expected growth of aquaculture are set in the context of sustainable intensification, with the challenges that conventional intensification and emergent integration within, and between, value chains explored. The review concludes with a consideration of the implications for dependent livelihoods and projections for various futures based on limited resources but growing demand.

  6. Rapidly growing tropical trees mobilize remarkable amounts of nitrogen, in ways that differ surprisingly among species. (United States)

    Russell, Ann E; Raich, James W


    Fast-growing forests such as tropical secondary forests can accumulate large amounts of carbon (C), and thereby play an important role in the atmospheric CO(2) balance. Because nitrogen (N) cycling is inextricably linked with C cycling, the question becomes: Where does the N come from to match high rates of C accumulation? In unique experimental 16-y-old plantations established in abandoned pasture in lowland Costa Rica, we used a mass-balance approach to quantify N accumulation in vegetation, identify sources of N, and evaluate differences among tree species in N cycling. The replicated design contained four broad-leaved evergreen tree species growing under similar environmental conditions. Nitrogen uptake was rapid, reaching 409 (± 30) kg · ha(-1) · y(-1), double the rate reported from a Puerto Rican forest and greater than four times that observed at Hubbard Brook Forest (New Hampshire, USA). Nitrogen amassed in vegetation was 874 (± 176) kg · ha(-1), whereas net losses of soil N (0-100 cm) varied from 217 (±146) to 3,354 (± 915) kg · ha(-1) (P = 0.018) over 16 y. Soil C:N, δ(13)C values, and N budgets indicated that soil was the main source of biomass N. In Vochysia guatemalensis, however, N fixation contributed >60 kg · ha(-1) · y(-1). All species apparently promoted soil N turnover, such that the soil N mean residence time was 32-54 y, an order of magnitude lower than the global mean. High rates of N uptake were associated with substantial N losses in three of the species, in which an average of 1.6 g N was lost for every gram of N accumulated in biomass.

    Full Text Available Rapidly growing mycobacteria (RGM are common soil saprophytes, but certain strains cause infections in human and animals. The infections due to RGM have been increasing in past decades and are often difficult to treat. The susceptibility to antibiotics is regularly evaluated in clinical isolates of RGM, but the data on soil RGM are missing. The objectives of this study was to isolate RGM from four grassland soils with different impact of manuring, and assess their resistance to antibiotics and the ability to grow at 37°C and 42°C. Since isolation of RGM from soil is a challenge, a conventional decontamination method (NaOH/malachite green/cycloheximide and a recent method based on olive oil/SDS demulsification were compared. The olive oil/SDS method was less efficient, mainly because of the emulsion instability and plate overgrowing with other bacteria. Altogether, 44 isolates were obtained and 23 representatives of different RGM genotypes were screened. The number of isolates per soil decreased with increasing soil pH, consistently with previous findings that mycobacteria were more abundant in low pH soils. Most of the isolates belonged to the Mycobacterium fortuitum group. The majority of isolates was resistant to 2-4 antibiotics. Multiresistant strains occurred also in a control soil that has a long history without the exposure to antibiotic-containing manure. Seven isolates grew at 37°C, including the species M. septicum and M. fortuitum known for infections in humans. This study shows that multiresistant RGM close to known human pathogens occur in grassland soils regardless the soil history of manuring.

Ribosomes are more strongly segregated from the nucleoids (chromosomal DNA than previous widefield fluorescence studies suggested. While most transcription may be co-translational, the evidence indicates that most translation occurs on free mRNA copies that have diffused from the nucleoids to a ribosome-rich region. Analysis of time-resolved images of the nucleoid spatial distribution after treatment with the transcription-halting drug rifampicin and the translation-halting drug chloramphenicol shows that both drugs cause nucleoid contraction on the 0-3 min timescale. This is consistent with the transertion hypothesis. We suggest that the longer-term (20-30 min nucleoid expansion after Rif treatment arises from conversion of 70S-polysomes to 30S and 50S subunits, which readily penetrate the nucleoids. Monte Carlo simulations of a polymer bead model built to mimic the chromosomal DNA and ribosomes (either 70S-polysomes or 30S and 50S subunits explain spatial segregation or mixing of ribosomes and nucleoids in terms of excluded volume and entropic effects alone. A comprehensive model of the transcription-translation-transertion system incorporates this new information about the spatial organization of the E. coli cytoplasm. We propose that transertion, which radially expands the nucleoids, is essential for recycling of 30S and 50S subunits from ribosome-rich regions back into the nucleoids. There they initiate co-transcriptional translation, which is an important mechanism for maintaining RNAP forward progress and protecting the nascent mRNA chain. Segregation of 70S-polysomes from the nucleoid may facilitate rapid growth by shortening the search time for ribosomes to find free mRNA concentrated outside the nucleoid and the search time for RNAP concentrated within the nucleoid to find transcription

  9. An automated system for rapid non-destructive enumeration of growing microbes.

    Directory of Open Access Journals (Sweden)

    Roanna London

    Full Text Available BACKGROUND: The power and simplicity of visual colony counting have made it the mainstay of microbiological analysis for more than 130 years. A disadvantage of the method is the long time required to generate visible colonies from cells in a sample. New rapid testing technologies generally have failed to maintain one or more of the major advantages of culture-based methods. PRINCIPAL FINDINGS: We present a new technology and platform that uses digital imaging of cellular autofluorescence to detect and enumerate growing microcolonies many generations before they become visible to the eye. The data presented demonstrate that the method preserves the viability of the microcolonies it detects, thus enabling generation of pure cultures for microbial identification. While visual colony counting detects Escherichia coli colonies containing about 5x10(6 cells, the new imaging method detects E. coli microcolonies when they contain about 120 cells and microcolonies of the yeast Candida albicans when they contain only about 12 cells. We demonstrate that digital imaging of microcolony autofluorescence detects a broad spectrum of prokaryotic and eukaryotic microbes and present a model for predicting the time to detection for individual strains. Results from the analysis of environmental samples from pharmaceutical manufacturing plants containing a mixture of unidentified microbes demonstrate the method's improved test turnaround times. CONCLUSION: This work demonstrates a new technology and automated platform that substantially shortens test times while maintaining key advantages of the current methods.

    Six strains of a rapidly growing scotochromogenic mycobacterium were isolated from pulmonary specimens of independent patients. Biochemical and cultural tests were not suitable for their identification. The mycolic acid pattern analysed by HPLC was different from that of any other mycobacterium. Genotypic characterization, targeting seven housekeeping genes, revealed the presence of microheterogeneity in all of them. Different species were more closely related to the test strains in various regions: the type strain of Mycobacterium moriokaense showed 99.0 % 16S rRNA gene sequence similarity, and 91.5-96.5 % similarity for the remaining six regions. The whole genome sequences of the proposed type strain and that of M. moriokaense presented an average nucleotide identity (ANI) of 82.9 %. Phylogenetic analysis produced poorly robust trees in most genes with the exception of rpoB and sodA where Mycobacterium flavescens and Mycobacterium novocastrense were the closest species. This phylogenetic relatedness was confirmed by the tree inferred from five concatenated genes, which was very robust. The polyphasic characterization of the test strains, supported by the ANI value, demonstrates that they belong to a previously unreported species, for which the name Mycobacterium celeriflavum sp. nov. is proposed. The type strain is AFPC-000207(T) ( = DSM 46765(T) = JCM 18439(T)). © 2015 IUMS.

    Rapidly growing nontuberculous mycobacteria (RGNTM) have yet to be described in combat-related injuries. This study investigates the epidemiology, clinical findings, treatment, and outcomes of RGNTM infections among combat casualties wounded in Afghanistan from 2010 to 2012. Patients with RGNTM were identified from the Department of Defense Trauma Registry through the Trauma Infectious Disease Outcomes Study. Trauma history, surgical management, and clinical data were collected. Six isolates from patients requiring antimycobacterial therapy were sequenced. Seventeen cases were identified. Six cases, predominantly associated with Mycobacterium abscessus, required aggressive debridement and a median of 180 days of multidrug antimycobacterial therapy that included clofazimine. M. abscessus isolates expressed the erythromycin resistance methylase (erm(41)) gene for inducible macrolide resistance, yet there were no clinical treatment failures when macrolides were utilized in combination therapy. No clonal similarity between M. abscessus isolates was found. Eleven cases had positive wound cultures, but did not require antimycobacterial therapy. The median duration of time of injury to first detection of a RGNTM was 57 days. This represents the first report of RGNTM infections in war-wounded patients. RGNTM should be recognized as potential pathogens in grossly infected combat wounds. Surgical debridement and multidrug antimycobacterial therapy, when clinically indicated, was associated with satisfactory clinical outcomes.

    To identify the distribution and frequency of computed tomography (CT) findings in patients with nosocomial rapidly growing mycobacterial (RGM) infection after laparoscopic surgery. A descriptive retrospective study in patients with RGM infection after laparoscopic surgery who underwent CT imaging prior to initiation of therapy. The images were analyzed by two radiologists in consensus, who evaluated the skin/subcutaneous tissues, the abdominal wall, and intraperitoneal region separately. The patterns of involvement were tabulated as: densification, collections, nodules (≥1.0 cm), small nodules (<1.0 cm), pseudocavitated nodules, and small pseudocavitated nodules. Twenty-six patients met the established criteria. The subcutaneous findings were: densification (88.5 %), small nodules (61.5 %), small pseudocavitated nodules (23.1 %), nodules (38.5 %), pseudocavitated nodules (15.4 %), and collections (26.9 %). The findings in the abdominal wall were: densification (61.5 %), pseudocavitated nodules (3.8 %), and collections (15.4 %). The intraperitoneal findings were: densification (46.1 %), small nodules (42.3 %), nodules (15.4 %), and collections (11.5 %). Subcutaneous CT findings in descending order of frequency were: densification, small nodules, nodules, small pseudocavitated nodules, pseudocavitated nodules, and collections. The musculo-fascial plane CT findings were: densification, collections, and pseudocavitated nodules. The intraperitoneal CT findings were: densification, small nodules, nodules, and collections.

    With the advent of cone beam computed tomography (CBCT), it is now possible to quantitatively evaluate the effects of rapid maxillary expansion (RME) on the entire maxillary complex in growing patients. The purpose of this study is to use three-dimensional images to evaluate the displacement that occurs at the circummaxillary sutures (frontonasal, zygomaticomaxillary, intermaxillary, midpalatal, and transpalatal sutures) following rapid maxillary expansion in growing children. The CBCT scans of 25 consecutively treated RME patients (10 male, 15 female) with mean age of 12.3±2.6 years, were examined before expansion and immediately following the last activation of the expansion appliance. Statistically significant (Pmaxillary first molars due to RME was also statistically significant. There was no statistically significant displacement of the transpalatal suture. Rapid maxillary expansion results in significant displacement of the bones of circummaxillary sutures in growing children.

  14. Parents are rapidly getting older in South Korea. (United States)

    Sohn, Kitae


    While scholars and policymakers have investigated the causes and consequences of low fertility, they have neglected a related issue: advanced parental age. This is an important issue because advanced parental age adversely affects babies in the short and long run. South Korea recently topped the list of low-fertility countries, and so this study examined the trends in parental age in this country. We analysed all births between 1997 and 2014, the census for 2000 and 2010, and aggregate marriage data to report the trends in age at first marriage, interval from marriage to first birth, and parental age at first birth and at all births. At every stage, age increased rapidly for both parents. As a result, of babies born to fathers aged 20-54, 20.2% were born to fathers aged 35-54 in 2000 with the proportion increasing to 38.7% in 2010 - almost double in a single decade. The corresponding figures for mothers increased from 6.7% to 17.2% - more than double. Potential parents and policymakers can use this information to time births more appropriately, thereby reducing risks to babies and mothers.

    Two rapidly growing mycobacteria with identical 16S rRNA gene sequences were the subject of a polyphasic taxonomic study. The strains formed a well-supported subclade in the mycobacterial 16S rRNA gene tree and were most closely associated with the type strain of Mycobacterium novocastrense. Single and multilocus sequence analyses based on hsp65, rpoB and 16S rRNA gene sequences showed that strains SN 1900T and SN 1904T are phylogenetically distinct but share several chemotaxonomic and phenotypic features that are are consistent with their classification in the genus Mycobacterium. The two strains were distinguished by their different fatty acid and mycolic acid profiles, and by a combination of phenotypic features. The digital DNA-DNA hybridization (dDDH) and average nucleotide identity (ANI) values for strains SN 1900T and SN 1904T were 61.0 % and 94.7 %, respectively; in turn, the corresponding dDDH and ANI values with M. novocastrense DSM 44203T were 41.4 % and 42.8 % and 89.3 % and 89.5 %, respectively. These results show that strains SN1900T and SN 1904T form new centres of taxonomic variation within the genus Mycobacterium. Consequently, strains SN 1900T (40T=CECT 8763T=DSM 43219T) and SN 1904T (2409T=CECT 8766T=DSM 43532T) are considered to represent novel species, for which the names Mycobacteriumlehmannii sp. nov. and Mycobacteriumneumannii sp. nov. are proposed. A strain designated as 'Mycobacteriumacapulsensis' was shown to be a bona fide member of the putative novel species, M. lehmannii.

    ABSTRACT OBJECTIVE To evaluate the adequacy of the Clinical-Functional Vulnerability Index-20, a rapid triage instrument to test vulnerability in Brazilian older adults, for the use in primary health care. METHODS The study included convenience sample of 397 patients aged older than or equal to 60 years attended at Centro de Referência para o Idoso (Reference Center for Older Adults) and of 52 older adults the same age attended at the community. The results of the questionnaire, consisting of 20 questions, were compared with those of the Comprehensive Geriatric Assessment, considered a reference for identifying frail older adults. Spearman’s correlation was evaluated in the Clinical-Functional Vulnerability Index-20 with the Comprehensive Geriatric Assessment; the validity was verified by the area under the ROC curve; reliability was estimated by the percentage of agreement among evaluators and by the kappa coefficient, both with quadratic weighted. The cut-off point was obtained based on the higher accuracy criterion. Cronbach’s alpha, a measure of internal consistency, was estimated. RESULTS The Spearman’s correlation coefficient was high and positive for both groups (0.792 for older adults attended at the Reference Center and 0.305 for older adults from the community [p < 0.001]). The area under the ROC curve for older adults attended at the Reference Center was substantial (0.903). The cut-off point obtained was six, and older adults with scores in Clinical-Functional Vulnerability Index-20 above that value had strong possibility of being frail. For older adults from the community, the quadratic weighted agreement among evaluators was 99.5%, and the global quadratic weighted kappa coefficient was 0.94. Cronbach’s alpha was high for older adults attended at the Reference Center (0.861) and those attended at the community (0.740). CONCLUSIONS The Clinical-Functional Vulnerability Index-20 questionnaire, in the sample examined, turned out to be positively

    Full Text Available Abstract Background The aim of this pilot randomized controlled trial (RCT was to evaluate the sagittal mandibular response induced by rapid maxillary expansion (RME therapy in mixed dentition patients with class II malocclusion, comparing the effects of bonded RME and banded RME with a matched untreated class II control group. Methods This RCT was designed in parallel with an allocation ratio of 1:1:1. The sample consisted of 30 children with a mean age of 8.1 ± 0.6 years who were randomly assigned to three groups: group 1 treated with bonded RME, group 2 treated with banded RME, and group 3 the untreated control group. All patients met the following inclusion criteria: early mixed dentition, class II molar relationship, transverse discrepancy ≥ 4 mm, overjet ≥ 5 mm, and prepubertal skeletal maturity stage (CS1–CS2. The expansion screw was activated one quarter of a turn per day (0.25 mm until overcorrection was reached. For each subject, lateral cephalograms and plaster casts were obtained before treatment (T1 and after 1 year (T2. A randomization list was created for the group assignment, with an allocation ratio of 1:1:1. The observer who performed all the measurements was blinded to group assignment. The study was single-blinded in regard to statistical analysis. Results RME was effective in the correction of maxillary deficiency. Class II patients treated with both types of RME showed no significant improvement of the anteroposterior relationship of the maxilla and the mandible at both skeletal and occlusal levels. The acrylic splint RME had significant effects on reducing the skeletal vertical dimension and the gonial angle. Conclusions The orthopedic expansion did not affect the sagittal relationship of class II patients treated in the early mixed dentition when compared with the untreated control group. Additional studies with a larger sample are warranted to elucidate individual variations in dento-skeletal mandibular

    To study the clinical features, diagnosis and treatment of non-tuberculous mycobacterial keratitis (NTMK). It was retrospective case series study. Twelve eyes in 12 patients with NTMK following corneal foreign body trauma in 2007 were studied retrospectively including the case histories, clinical findings, laboratory examinations, diagnosis, treatment and prognosis. The main laboratory examination included corneal scrapings by culturing, polymerase chain reaction (PCR) and transmission electron microscopy (TEM), corneal lesions by histopathologic examinations and TEM. The patients received local and systemic antibiotics therapy, lesion cleaning followed by cauterization with tincture of iodine (5%) and (or) keratoplasty. All cases had a history of corneal trauma, there was corneal metallic foreign body removal at one hospital in 11 cases, corneal reed trauma in 1 case. The characteristic signs involved grayish-blue crystalloid keratopathy, multifocal infiltrates, satellites, radical form changes in the Descemet's membrane. The results of laboratory examinations of the scrapings of the cornea infection were as follows: all cultures (12/12) were positive for rapidly growing mycobacteria, and isolates from 5 patients were all diagnosed as mycobacterium chelonae subspecies abscess; acid-fast staining revealed positive bacilli in all the 4 patients; seven of 8 patients were positive for bacterium by PCR. Transmission electron microscopy in all the 3 specimens showed many slender rod-shaped or short coarse-shaped bacteria which were phagocytized by monocytes, and some necrotic tissue. Infections in 10 eyes were resolved by combined treatment regimen including a combination of antimicrobial agents (amikacin, rifampin, gatifloxacin, ciprofloxacin, azithromycin and/or ofloxacin, etc.) and local lesion cleaning followed by cauterization with 5% tincture of iodine within 2-5 months; two cases resolved by keratoplasty which poorly responded to antibiotic therapy for 6 months

    Both financial literacy (managing personal finances) and health literacy (managing personal health) become increasingly important for older adults, potentially impacting their quality of life. Resources in these constructs of literacy tend to be distinct, although the skills and decision-making involved overlap as financial issues impact healthcare choices. Thus the primary purpose of this commentary is to propose a new area of research focus that defines the intersection of financial and health literacy (i.e., financial health literacy). We conducted a limited literature review related to financial, health, and health insurance literacy to demonstrate gaps in the literature and support our position. Online search engines were utilized to identify research in our primary areas of interest. We define the intersection of financial and health literacy as an area of need labeled financial health literacy, with a focus on four domains. These include: 1) the ability to manage healthcare expenses; 2) pay medical bills; 3) determine health needs and understand treatment options; and 4) make sound healthcare decisions with financial resources available. Despite some overlap with health insurance literacy, financial health literacy would define an area of need encompassing health management choices and health plan selections integrated with other financial management issues including living arrangements, financial planning, and retirement planning. Potential initiatives should be considered to help at-risk older adults find resources to improve their financial health literacy, which in turn will enhance their abilities to manage medical choices in the environment of an increasingly complex healthcare system.

    During 2013, the Maryland Department of Health and Mental Hygiene in Baltimore, MD, USA, received report of 2 Maryland residents whose surgical sites were infected with rapidly growing mycobacteria after cosmetic procedures at a clinic (clinic A) in the Dominican Republic. A multistate investigation was initiated; a probable case was defined as a surgical site infection unresponsive to therapy in a patient who had undergone cosmetic surgery in the Dominican Republic. We identified 21 case-patients in 6 states who had surgery in 1 of 5 Dominican Republic clinics; 13 (62%) had surgery at clinic A. Isolates from 12 (92%) of those patients were culture-positive for Mycobacterium abscessus complex. Of 9 clinic A case-patients with available data, all required therapeutic surgical intervention, 8 (92%) were hospitalized, and 7 (78%) required ≥3 months of antibacterial drug therapy. Healthcare providers should consider infection with rapidly growing mycobacteria in patients who have surgical site infections unresponsive to standard treatment.

  7. A novel culture medium for isolation of rapidly-growing mycobacteria from the sputum of patients with cystic fibrosis. (United States)

    Isolation of mycobacteria from the sputum of patients with cystic fibrosis (CF) is challenging due to the overgrowth of cultures by other bacteria and fungi. In this setting, Burkholderia cepacia selective agar (BCSA) has been recommended as a convenient and effective culture medium for the isolation of rapidly-growing, non-tuberculous mycobacteria (NTM). A novel selective culture medium (RGM medium) was evaluated for the isolation of rapidly-growing NTM from the sputum of children and adults with CF. A total of 118 isolates of rapidly-growing mycobacteria and 98 other bacteria and fungi were inoculated onto RGM medium. These were assessed for growth at 30°C over a seven day period. A total of 502 consecutive sputum samples were collected from 210 patients with CF. Each sample was homogenized and cultured onto RGM medium and also onto BCSA. Cultures were incubated for 10days at 30°C. Of 118 isolates of mycobacteria all but one grew well on RGM medium, whereas 94% of other bacteria and fungi were inhibited. A total of 55 sputum samples (from 33 distinct patients) yielded NTM using a combination of both RGM and BCSA (prevalence: 15.7%). NTM were recovered from 54 sputum samples using RGM medium compared with only 17 samples using BCSA (sensitivity 98% vs. 31%; P≤0.0001). A total of 419 isolates of non-mycobacteria were recovered from sputum samples on BCSA compared with 46 on RGM medium. RGM medium offers a simple and effective culture method for the isolation of rapidly-growing mycobacteria from sputum samples from patients with CF without decontamination of samples. RGM medium allows for the systematic screening of all sputum samples routinely referred for culture from patients with CF. Copyright © 2015 European Cystic Fibrosis Society.

    Full Text Available INTRODUCTION: With the advent of cone beam computed tomography (CBCT, it is now possible to quantitatively evaluate the effects of rapid maxillary expansion (RME on the entire maxillary complex in growing patients. OBJECTIVE: The purpose of this study is to use three-dimensional images to evaluate the displacement that occurs at the circummaxillary sutures (frontonasal, zygomaticomaxillary, intermaxillary, midpalatal, and transpalatal sutures following rapid maxillary expansion in growing children. METHODS: The CBCT scans of 25 consecutively treated RME patients (10 male, 15 female with mean age of 12.3 ± 2.6 years, were examined before expansion and immediately following the last activation of the expansion appliance. RESULTS: Statistically significant (P < 0.05 amounts of separation were found for the displacement of the bones of the frontonasal suture, the intermaxillary suture, the zygomaticomaxillary sutures, and the midpalatal suture. The change in angulation of the maxillary first molars due to RME was also statistically significant. There was no statistically significant displacement of the transpalatal suture. CONCLUSIONS: Rapid maxillary expansion results in significant displacement of the bones of circummaxillary sutures in growing children.

  10. Women growing older with environmental sensitivities: A grounded theory model of meeting one's needs. (United States)

    Gibson, Pamela Reed; Horan, Mary Cate; Billy, Jacqueline


    This article describes a telephone interview study of 21 women over the age of 65 with environmental sensitivities (ES), including both chemical and electrical hypersensitivities. We employed Charmaz's constructivist grounded theory, using incident, focused, and theoretical coding levels. We were interested in how informants thought their needs would be met as they grew older with ES. We found a central process (that which motivates informants) of "balancing on a changing tightrope with great overwhelm" with three categories: No Safety Net, The Knowing, and Going Through the Cracks. No Safety Net refers to the inaccessibility of most community and health resources for persons who must avoid chemicals, electromagnetic fields, or both. The Knowing refers to having the awareness that one has been dealt out of the equation and will not receive help from conventional sources. Going Through the Cracks describes living one's life by finding small openings and opportunities for living and experiencing what most take for granted. We describe these categories in detail and appeal to health care providers and the general public to view culture through the eyes of those who are unable to participate in it to an extent considered "normal."

  11. Rapidly growing cystic vestibular schwannoma with sudden onset facial palsy, ten years after subtotal excision. (United States)

    Dandinarasaiah, Manjunath; Grinblat, Golda; Prasad, Sampath Chandra; Taibah, Abdelkader; Sanna, Mario


    An elderly male patient diagnosed with a right-sided cystic vestibular schwannoma (CVS) at our center underwent a translabyrinthine approach with a subtotal excision to preserve the facial nerve (FN). The tumor grew slowly for the first 9 years but in the subsequent 2 years grew rapidly, with the patient developing a FN paralysis. Using the previous approach, a second surgery was done and the tumor was excised, leaving behind a sheath of tumor on the facial and lower cranial nerves. This case demonstrates that CVSs show unpredictable growth patterns and need to be followed up for a longer period of time.

  12. In-vitro evaluation of the adhesion to polypropylene sutures of non-pigmented, rapidly growing mycobacteria. (United States)

    Zamora, N; Esteban, J; Kinnari, T J; Celdrán, A; Granizo, J J; Zafra, C


    The ability of non-pigmented, rapidly growing mycobacteria (NPRGM) to attach to polypropylene sutures was evaluated using an in-vitro assay. Thirty clinical isolates and five culture collection strains of NPRGM, together with Staphylococcus epidermidis ATCC 35983, were tested. Mycobacterium fortuitum and Mycobacterium chelonae showed the highest attachment ability, which differed significantly from the results obtained with Mycobacterium peregrinum. According to these results, NPRGM are able to attach to polypropylene sutures, and the species implicated most frequently in human infection showed increased levels of attachment in comparison with the other mycobacteria studied.

  13. Total daily activity declines more rapidly with increasing age in older adults. (United States)

    Buchman, Aron S; Wilson, Robert S; Yu, Lei; James, Bryan D; Boyle, Patricia A; Bennett, David A


    Longitudinal studies of objectively measured physical activity are lacking in older adults. We tested whether objective measures of total daily activity decline more rapidly in older adults. This prospective, observational cohort study included 519 community-dwelling older persons from across metropolitan Chicago participating in the Rush Memory and Aging Project. Repeated total daily activity measures (leisure and non-leisure physical activity) were derived from actigraphic recordings for up to 10 days. Generalized estimating equation models which controlled for demographics measures were employed. At baseline, age was inversely related with the level of total daily activity (estimate, -0.014, S.E. 0.002, pdaily activity declined by about 0.070 × 10(5) activity counts/day/yr (estimate -0.065, S.E. 0.005, pdaily activity declined 3% more rapidly for each additional year of age at baseline (estimate -0.002, S.E. 0.001, p=0.027). Thus, total daily activity declined almost twice as fast in an individual 91 years old at baseline versus an individual 71 years old. A higher level of education was associated with a slower rate of decline (estimate 0.004, S.E. 0.002, pdaily activity were unchanged when controlling for baseline level of motor and cognitive function, other late-life activities and chronic health conditions. These data suggest that total daily activity in very old adults declines more rapidly with increasing age. Thus, physical inactivity is likely to become a larger problem in our aging population.

  14. A rapidly growing moraine-dammed glacial lake on Ngozumpa Glacier, Nepal (United States)

    Thompson, Sarah S.; Benn, Douglas I.; Dennis, Kathryn; Luckman, Adrian


    Moraine-dammed glacial lakes are becoming increasingly common in the Himalaya as a result of glacier mass loss, causing concern about glacier lake outburst flood risk. In addition to extant lakes, the potential exists for many more to form, as more glaciers ablate down to the level of potential moraine dams. In this paper, we document the recent rapid growth of, a moraine-dammed lake on Ngozumpa Glacier, Nepal. Using a combination of ground-based mapping and sonar surveys, aerial photographs (< 1 m resolution), and ASTER imagery (15 m resolution), processes and rates of lake expansion have been determined. The lake first formed between 1984 and 1992 when collapse of an englacial conduit allowed water to accumulate at the level of a gap in the lateral moraine, ~km from the glacier terminus. Lake growth was initially slow, but since 2001 it has undergone exponential growth at an average rate of 10% y-1. In 2009, the lake area was 300,000 m2, and its volume was at least 2.2 million m3. Calving, subaqueous melting, and melting of subaerial ice faces all contribute to the expansion of the lake; but large-scale, full-height slab calving is now the dominant contributor to growth. Comparison with other lakes in the region indicate that lake growth will likely continue unchecked whilst the spillway remains at its current level and may attain a volume of hundreds of millions of cubic metres within the next few decades.

  15. Neonatal sepsis in a rapidly growing, tertiary neonatal intensive care unit: Trends over 18 years. (United States)

    Heo, Ju Sun; Shin, Seung Han; Jung, Young Hwa; Kim, Ee-Kyung; Choi, Eun Hwa; Kim, Han-Suk; Lee, Hoan Jong; Choi, Jung-Hwan


    We investigated changes in the admission patterns of neonatal intensive care units and the epidemiology of neonatal sepsis following the rapid expansion and improvements in neonatal intensive care. Data on the admission of neonates with culture-proven sepsis between 1996 and 2013 (period I, 1996-2005; period II, 2006-2013) were collected retrospectively. The admission of extremely low-birthweight (ELBW) infants increased between periods I and II (11.1 vs 28.7 infants per 1000 live births, P sepsis among all infants and ELBW infants increased (all infants, 5.9 vs 12.7 cases per 1000 live births; ELBW infants, 189.5 vs 290.1 cases per 1000 live births). In ELBW infants, the incidence of sepsis caused by coagulase-negative Staphylococcus (CONS), significantly increased during period II (8.8 vs 25.4%, P = 0.039). On multivariate analysis, central vascular catheters and prolonged hospitalization were independently associated with increased sepsis rate, particularly CONS in ELBW infants. The inborn admission rate for ELBW infants has increased significantly and is accompanied by improved survival and longer hospital stay. The incidence of neonatal sepsis, particularly in ELBW infants, has also increased, and CONS has emerged as a major pathogen. Central vascular catheters and prolonged hospitalization could be independent risk factors for the increased sepsis rate, particularly sepsis due to CONS. © 2015 Japan Pediatric Society.

  16. The effect of valence on young and older adults' attention in a rapid serial visual presentation task. (United States)

    Steinmetz, Katherine R Mickley; Muscatell, Keely A; Kensinger, Elizabeth A


    Using a rapid serial visual presentation task, the authors examined how the emotional valence of a word affected young and older adults' abilities to detect another word that closely followed it in temporal proximity. Both age groups detected neutral words better when such words followed a positive or negative arousing word rather than a neutral arousing word. These results suggest that emotion influences attention in a similar fashion for young and older adults. Despite evidence that older adults can sometimes show a "positivity effect" in memory, we found no evidence of increased attention toward positive words for older adults.

  17. Rapidly developing multimorbidity and disability in older adults: does social background matter? (United States)

    Calderón-Larrañaga, Amaia; Santoni, Giola; Wang, Hui Xin; Welmer, Anna-Karin; Rizzuto, Debora; Vetrano, Davide L; Marengoni, Alessandra; Fratiglioni, Laura


    Multimorbidity is among the most disabling geriatric conditions. In this study we explored whether a rapid development of multimorbidity potentiates its impact on the functional independence of older adults, and whether different sociodemographic factors play a role beyond the rate of chronic disease accumulation. A random sample of persons aged ≥60 years (n = 2387) from the Swedish National study on Aging and Care in Kungsholmen (SNAC-K) was followed over 6 years. The speed of multimorbidity development was estimated as the rate of chronic disease accumulation (linear mixed models) and further dichotomized into the upper versus the three lower rate quartiles. Binomial negative mixed models were used to analyse the association between speed of multimorbidity development and disability (impaired basic and instrumental activities of daily living), expressed as the incidence rate ratio (IRR). The effect of sociodemographic factors, including sex, education, occupation and social network, was investigated. The risk of new activity impairment was higher among participants who developed multimorbidity faster (IRR 2.4, 95% CI 1.9-3.1) compared with those who accumulated diseases more slowly over time, even after considering the baseline number of chronic conditions. Only female sex (IRR for women vs. men 1.6, 95% CI 1.2-2.0) and social network (IRR for poor vs. rich social network 1.7, 95% CI 1.3-2.2) showed an effect on disability beyond the rate of chronic disease accumulation. Rapidly developing multimorbidity is a negative prognostic factor for disability. However, sociodemographic factors such as sex and social network may determine older adults' reserves of functional ability, helping them to live independently despite rapid accumulation of chronic conditions.

  18. Mycobacterium grossiae sp. nov., a rapidly growing, scotochromogenic species isolated from human clinical respiratory and blood culture specimens. (United States)

    Paniz-Mondolfi, Alberto Enrique; Greninger, Alexander L; Ladutko, Lynn; Brown-Elliott, Barbara A; Vasireddy, Ravikiran; Jakubiec, Wesley; Vasireddy, Sruthi; Wallace, Richard J; Simmon, Keith E; Dunn, Bruce E; Jackoway, Gary; Vora, Surabhi B; Quinn, Kevin K; Qin, Xuan; Campbell, Sheldon


    A previously undescribed, rapidly growing, scotochromogenic species of the genus Mycobacterium (represented by strains PB739 T and GK) was isolated from two clinical sources - the sputum of a 76-year-old patient with severe chronic obstructive pulmonary disease, history of tuberculosis exposure and Mycobacterium avium complex isolated years prior; and the blood of a 15-year-old male with B-cell acute lymphoblastic leukaemia status post bone marrow transplant. The isolates grew as dark orange colonies at 25-37 °C after 5 days, sharing features in common with other closely related species. Analysis of the complete 16S rRNA gene sequence (1492 bp) of strain PB739 T demonstrated that the isolate shared 98.8 % relatedness with Mycobacterium wolinskyi. Partial 429 bp hsp65 and 744 bp rpoB region V sequence analyses revealed that the sequences of the novel isolate shared 94.8 and 92.1 % similarity with those of Mycobacterium neoaurum and Mycobacterium aurum, respectively. Biochemical profiling, antimicrobial susceptibility testing, HPLC/gas-liquid chromatography analyses and multilocus sequence typing support the taxonomic status of these isolates (PB739 T and GK) as representatives of a novel species. Both isolates were susceptible to the Clinical and Laboratory Standards Institute recommended antimicrobials for susceptibility testing of rapidly growing mycobacteria including amikacin, ciprofloxacin, moxifloxacin, doxycycline/minocycline, imipenem, linezolid, clarithromycin and trimethropin/sulfamethoxazole. Both isolates PB739 T and GK showed intermediate susceptibility to cefoxitin. We propose the name Mycobacterium grossiae sp. nov. for this novel species and have deposited the type strain in the DSMZ and CIP culture collections. The type strain is PB739 T (=DSM 104744 T =CIP 111318 T ).

    Cusumano, Lucas R; Tran, Vivy; Tlamsa, Aileen; Chung, Philip; Grossberg, Robert; Weston, Gregory; Sarwar, Uzma N


    Medical tourism is increasingly popular for elective cosmetic surgical procedures. However, medical tourism has been accompanied by reports of post-surgical infections due to rapidly growing mycobacteria (RGM). The authors' experience working with patients with RGM infections who have returned to the USA after traveling abroad for cosmetic surgical procedures is described here. Patients who developed RGM infections after undergoing cosmetic surgeries abroad and who presented at the Montefiore Medical Center (Bronx, New York, USA) between August 2015 and June 2016 were identified. A review of patient medical records was performed. Four patients who presented with culture-proven RGM infections at the sites of recent cosmetic procedures were identified. All patients were treated with a combination of antibiotics and aggressive surgical treatment. This case series of RGM infections following recent cosmetic surgeries abroad highlights the risks of medical tourism. Close monitoring of affected patients by surgical and infectious disease specialties is necessary, as aggressive surgical debridement combined with appropriate antibiotic regimens is needed to achieve cure. Given the increasing reports of post-surgical RGM infections, consultants should have a low threshold for suspecting RGM, as rapid diagnosis may accelerate the initiation of targeted treatment and minimize morbidity.

    Moraes, Edgar Nunes de; Carmo, Juliana Alves do; Moraes, Flávia Lanna de; Azevedo, Raquel Souza; Machado, Carla Jorge; Montilla, Dalia Elena Romero


    To evaluate the adequacy of the Clinical-Functional Vulnerability Index-20, a rapid triage instrument to test vulnerability in Brazilian older adults, for the use in primary health care. The study included convenience sample of 397 patients aged older than or equal to 60 years attended at Centro de Referência para o Idoso (Reference Center for Older Adults) and of 52 older adults the same age attended at the community. The results of the questionnaire, consisting of 20 questions, were compared with those of the Comprehensive Geriatric Assessment, considered a reference for identifying frail older adults. Spearman's correlation was evaluated in the Clinical-Functional Vulnerability Index-20 with the Comprehensive Geriatric Assessment; the validity was verified by the area under the ROC curve; reliability was estimated by the percentage of agreement among evaluators and by the kappa coefficient, both with quadratic weighted. The cut-off point was obtained based on the higher accuracy criterion. Cronbach's alpha, a measure of internal consistency, was estimated. The Spearman's correlation coefficient was high and positive for both groups (0.792 for older adults attended at the Reference Center and 0.305 for older adults from the community [p idosos brasileiros, para utilização pela atenção básica. O estudo incluiu amostra de conveniência de 397 pacientes com idade maior ou igual a 60 anos atendidos em um Centro de Referência para o Idoso e de 52 idosos da mesma idade atendidos na comunidade. Os resultados do questionário, constituído por 20 perguntas, foram comparados com aqueles da Avaliação Geriátrica Ampla, considerada referência para identificação do idoso frágil. Foi avaliada a correlação de Spearman do Índice de Vulnerabilidade Clínico-Funcional-20 com a Avaliação Geriátrica Ampla; a validade foi verificada pela área sob a curva ROC; a confiabilidade foi estimada pelo percentual de concordância entre avaliadores e coeficiente kappa

  1. Mycobacterium oryzae sp. nov., a scotochromogenic, rapidly growing species is able to infect human macrophage cell line. (United States)

    Ramaprasad, E V V; Rizvi, A; Banerjee, S; Sasikala, Ch; Ramana, Ch V


    Gram-stain-positive, acid-fast-positive, rapidly growing, rod-shaped bacteria (designated as strains JC290T, JC430 and JC431) were isolated from paddy cultivated soils on the Western Ghats of India. Phylogenetic analysis placed the three strains among the rapidly growing mycobacteria, being most closely related to Mycobacterium tokaiense 47503T (98.8 % 16S rRNA gene sequence similarity), Mycobacterium murale MA112/96T (98.8 %) and a few other Mycobacterium species. The level of DNA-DNA reassociation of the three strains with M. tokaiense DSM 44635T was 23.4±4 % (26.1±3 %, reciprocal analysis) and 21.4±2 % (22.1±4 %, reciprocal analysis). The three novel strains shared >99.9 % 16S rRNA gene sequence similarity and DNA-DNA reassociation values >85 %. Furthermore, phylogenetic analysis based on concatenated sequences (3071 bp) of four housekeeping genes (16S rRNA, hsp65, rpoB and sodA) revealed that strain JC290T is clearly distinct from all other Mycobacteriumspecies. The three strains had diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositolmannosides, unidentified phospholipids, unidentified glycolipids and an unidentified lipid as polar lipids. The predominant isoprenoid quinone for all three strains was MK-9(H2). Fatty acids were C17 : 1ω7c, C16 : 0, C18 : 1ω9c, C16 : 1ω7c/C16 : 1ω6c and C19 : 1ω7c/C19 : 1ω6c for all the three strains. On the basis of phenotypic, chemotaxonomic and phylogenetic data, it was concluded that strains JC290T, JC430 and JC431 are members of a novel species within the genus Mycobacterium and for which the name Mycobacterium oryzae sp. nov. is proposed. The type strain is JC290T (=KCTC 39560T=LMG 28809T).

  2. Miniaturized extinction culturing is the preferred strategy for rapid isolation of fast‐growing methane‐oxidizing bacteria (United States)

    Hoefman, Sven; van der Ha, David; De Vos, Paul; Boon, Nico; Heylen, Kim


    Summary Methane‐oxidizing bacteria (MOB) have a large potential as a microbial sink for the greenhouse gas methane as well as for biotechnological purposes. However, their application in biotechnology has so far been hampered, in part due to the relative slow growth rate of the available strains. To enable the availability of novel strains, this study compares the isolation of MOB by conventional dilution plating with miniaturized extinction culturing, both performed after an initial enrichment step. The extinction approach rendered 22 MOB isolates from four environmental samples, while no MOB could be isolated by plating. In most cases, extinction culturing immediately yielded MOB monocultures making laborious purification redundant. Both type I (Methylomonas spp.) and type II (Methylosinus sp.) MOB were isolated. The isolated methanotrophic diversity represented at least 11 different strains and several novel species based on 16S rRNA gene sequence dissimilarity. These strains possessed the particulate (100%) and soluble (64%) methane monooxygenase gene. Also, 73% of the strains could be linked to a highly active fast‐growing mixed MOB community. In conclusion, miniaturized extinction culturing was more efficient in rapidly isolating numerous MOB requiring little effort and fewer materials, compared with the more widely applied plating procedure. This miniaturized approach allowed straightforward isolation and could be very useful for subsequent screening of desired characteristics, in view of their future biotechnological potential.

  3. Looking age-appropriate while growing old gracefully: A qualitative study of ageing and body image among older adults. (United States)

    Jankowski, Glen S; Diedrichs, Phillippa C; Williamson, Heidi; Christopher, Gary; Harcourt, Diana


    Body dissatisfaction can be significantly detrimental to wellbeing. Little is known about older adults' body image, despite the fact that ageing causes unique bodily changes and that sociocultural pressures to resist these changes abound. We conducted six focus groups with a UK community sample of White British and South Asian older adults aged 65-92 years. Thematic analysis highlighted four themes: appearance indicates capability and identity; physical ability trumps appearance; felt pressures to age 'gracefully' while resisting appearance changes; and gender and cultural differences. These findings suggest that older adults' body image can have important implications for their wellbeing and merits researchers' attention. © The Author(s) 2014.

  4. Rapid Responsiveness to Practice Predicts Longer-Term Retention of Upper Extremity Motor Skill in Non-Demented Older Adults. (United States)

    Schaefer, Sydney Y; Duff, Kevin


    Skill acquisition is a form of motor learning that may provide key insights into the aging brain. Although previous work suggests that older adults learn novel motor tasks slower and to a lesser extent than younger adults, we have recently demonstrated no significant effect of chronological age on the rates and amounts of skill acquisition, nor on its long-term retention, in adults over the age of 65. To better understand predictors of skill acquisition in non-demented older adults, we now explore the relationship between early improvements in motor performance due to practice (i.e., rapid responsiveness) and longer-term retention of an upper extremity motor skill, and whether the extent of rapid responsiveness was associated with global cognitive status. Results showed significant improvements in motor performance within the first five (of 150) trials, and that this "rapid responsiveness" was predictive of skill retention 1 month later. Notably, the extent of rapid responsiveness was not dependent on global cognitive status, as measured by the Montreal Cognitive Assessment (MoCA). Thus, rapid responsiveness appears to be an important variable in longer-term neurorehabilitative efforts with older adults, regardless of their cognitive status.

  5. Mycobacterium saopaulense sp. nov., a rapidly growing mycobacterium closely related to members of the Mycobacterium chelonae--Mycobacterium abscessus group. (United States)

    Nogueira, Christiane Lourenço; Whipps, Christopher M; Matsumoto, Cristianne Kayoko; Chimara, Erica; Droz, Sara; Tortoli, Enrico; de Freitas, Denise; Cnockaert, Margo; Palomino, Juan Carlos; Martin, Anandi; Vandamme, Peter; Leão, Sylvia Cardoso


    Five isolates of non-pigmented, rapidly growing mycobacteria were isolated from three patients and,in an earlier study, from zebrafish. Phenotypic and molecular tests confirmed that these isolates belong to the Mycobacterium chelonae-Mycobacterium abscessus group, but they could not be confidently assigned to any known species of this group. Phenotypic analysis and biochemical tests were not helpful for distinguishing these isolates from other members of the M. chelonae–M.abscessus group. The isolates presented higher drug resistance in comparison with other members of the group, showing susceptibility only to clarithromycin. The five isolates showed a unique PCR restriction analysis pattern of the hsp65 gene, 100 % similarity in 16S rRNA gene and hsp65 sequences and 1-2 nt differences in rpoB and internal transcribed spacer (ITS) sequences.Phylogenetic analysis of a concatenated dataset including 16S rRNA gene, hsp65, and rpoB sequences from type strains of more closely related species placed the five isolates together, as a distinct lineage from previously described species, suggesting a sister relationship to a group consisting of M. chelonae, Mycobacterium salmoniphilum, Mycobacterium franklinii and Mycobacterium immunogenum. DNA–DNA hybridization values .70 % confirmed that the five isolates belong to the same species, while values ,70 % between one of the isolates and the type strains of M. chelonae and M. abscessus confirmed that the isolates belong to a distinct species. The polyphasic characterization of these isolates, supported by DNA–DNA hybridization results,demonstrated that they share characteristics with M. chelonae–M. abscessus members, butconstitute a different species, for which the name Mycobacterium saopaulense sp. nov. is proposed. The type strain is EPM10906T (5CCUG 66554T5LMG 28586T5INCQS 0733T).

    Fukano, Hanako; Wada, Shinpei; Kurata, Osamu; Katayama, Kinya; Fujiwara, Nagatoshi; Hoshino, Yoshihiko


    A previously undescribed rapidly growing, non-pigmented mycobacterium was identified based on biochemical and nucleic acid analyses, as well as growth characteristics. Seven isolates were cultured from samples collected from five thread-sail filefish (Stephanolepis cirrhifer) and two farmed black scraper (Thamnaconus modestus). Bacterial growth occurred at 15-35 °C on Middlebrook 7H11 agar. The bacteria were positive for catalase activity at 68 °C and urease activity, intermediate for iron uptake, and negative for Tween 80 hydrolysis, nitrate reduction, semi-quantitative catalase activity and arylsulfatase activity at day 3. No growth was observed on Middlebrook 7H11 agar supplemented with picric acid, and very little growth was observed in the presence of 5 % NaCl. α- and α'-mycolates were identified in the cell walls, and a unique profile of the fatty acid methyl esters and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) profiles of the protein and cell-wall lipids were acquired. Sequence analysis revealed that the seven isolates shared identical sequences for the 16S rRNA, rpoB, hsp65, recA and sodA genes. Phylogenetic analysis of the five gene sequences confirmed that the isolates were unique, but closely related to Mycobacterium chelonae. Antibiotic susceptibility testing revealed the minimum inhibitory concentration (MIC) of clarithromycin against this novel species was Mycobacterium salmoniphilum. The hsp65 PCR restriction enzyme analysis pattern differed from those of M. chelonae and M. salmoniphilum. Based on these findings, the name Mycobacterium stephanolepidis sp. nov. is proposed for this novel species, with the type strain being NJB0901T (=JCM 31611T=KCTC 39843T).

  9. Regulation of the efflux of putrescine and cadaverine from rapidly growing cultured RAW 264 cells by extracellular putrescine.


    Tjandrawinata, R R; Byus, C V


    Cultures of the macrophage-like RAW 264 cells were adapted to divide normally in a synthetic serum-supplemented culture medium lacking any polyamines and diamine oxidase activity. These rapidly dividing cells actively effluxed large amounts of putrescine and cadaverine, compared with the intracellular levels, into the culture medium. The efflux of putrescine was stimulated by the amino acid ornithine, whereas efflux of cadaverine was inhibited. Relatively low levels of spermidine and N1-acety...

    Conclusions: This case series of RGM infections following recent cosmetic surgeries abroad highlights the risks of medical tourism. Close monitoring of affected patients by surgical and infectious disease specialties is necessary, as aggressive surgical debridement combined with appropriate antibiotic regimens is needed to achieve cure. Given the increasing reports of post-surgical RGM infections, consultants should have a low threshold for suspecting RGM, as rapid diagnosis may accelerate the initiation of targeted treatment and minimize morbidity.

  11. Do farmers rapidly adapt to past growing conditions by sowing different proportions of early and late maturing cereals and cultivars?

    Directory of Open Access Journals (Sweden)

    Pirjo Peltonen-Sainio


    Full Text Available In the short growing season of the northernmost European growing conditions, farmers are increasingly interested in expanding cultivation of later maturing crops at the expense of early maturing ones with lower yields. In this study we aimed to assess how the switching between spring cereals that differ in earliness was associated with different external factors. This was tested using unique datasets for regional cropping areas and cultivar use for the last 15 years. Early maturing barley was favored at the expense of later maturing wheat when a high number of days to crop maturity was required in the preceding year. In contrast, farmers reduced the barley area when a high number of cumulated degree days was required for a crop to mature in the previous year. A shift was recorded from early to late maturing cultivars. This study indicated that despite limited opportunities for farmers to alter land use, they readily responded to past conditions and used the knowledge gained for decision-making to reduce risk. This is a valuable operative model for studying adaptation to opportunities and constraints induced by climate change.

  12. Undertaking a Collaborative Rapid Realist Review to Investigate What Works in the Successful Implementation of a Frail Older Person's Pathway.

    LENUS (Irish Health Repository)


    We addressed the research question "what factors enable the successful development and implementation of a frail older person\\'s pathway within the acute setting". A rapid realist review (RRR) was conducted by adopting the RAMESES standards. We began with a sample of 232 articles via database searches supplemented with 94 additional records including inputs from a twitter chat and a hospital site visit. Our final sample consisted of 18 documents. Following review and consensus by an expert panel we identified a conceptual model of context-mechanism-(resources)-outcomes. There was overall agreement frailty should be identified at the front door of the acute hospital. Significant challenges identified related to organisational boundaries both within the acute setting and externally, the need to shift outcomes to patient orientated ones, to support staff to sustain the pathway by providing ongoing education and by providing role clarity. RRRs can support research such as the systematic approach to improving care for frail older adults (SAFE) study by producing accounts of what works based on a wide range of sources and innovative engagement with stakeholders. It is evident from our provisional model that numerous factors need to combine and interact to enable and sustain a successful frail older person\\'s pathway.

    Full Text Available Northwest Arkansas has undergone a significant urban transformation in the past several decades and is considered to be one of the fastest growing regions in the United States. The urban area expansion and the associated demographic increases bring unprecedented pressure to the environment and natural resources. To better understand the consequences of urbanization, accurate and long-term depiction on urban dynamics is critical. Although urban mapping activities using remote sensing have been widely conducted, long-term urban growth mapping at an annual pace is rare and the low accuracy of change detection remains a challenge. In this study, a time series Landsat stack covering the period from 1995 to 2015 was employed to detect the urban dynamics in Northwest Arkansas via a two-stage classification approach. A set of spectral indices that have been proven to be useful in urban area extraction together with the original Landsat spectral bands were used in the maximum likelihood classifier and random forest classifier to distinguish urban from non-urban pixels for each year. A temporal trajectory polishing method, involving temporal filtering and heuristic reasoning, was then applied to the sequence of classified urban maps for further improvement. Based on a set of validation samples selected for five distinct years, the average overall accuracy of the final polished maps was 91%, which improved the preliminary classifications by over 10%. Moreover, results from this study also indicated that the temporal trajectory polishing method was most effective with initial low accuracy classifications. The resulting urban dynamic map is expected to provide unprecedented details about the area, spatial configuration, and growing trends of urban land-cover in Northwest Arkansas.

    Full Text Available Type I diabetes (T1D, mediated by autoreactive T cell destruction of insulin-producing islet beta cells, has been treated with bone marrow-derived hematopoietic stem cell (BM-HSC transplantation. Older non-obese diabetic (NOD mice recipients (3m, at disease-onset stage receiving syngeneic BM-HSC progressed more rapidly to end-stage diabetes post-transplantation than younger recipients (4-6w, at disease-initiation stage. FACS analyses showed a higher percentage and absolute number of regulatory T cells (Treg and lower proportion of proliferating T conventional cells (Tcon in pancreatic lymph nodes from the resistant mice among the younger recipients compared to the rapid progressors among the older recipients. Treg distribution in spleen, mesenteric lymph nodes (MLN, blood and thymus between the two groups was similar. However, the percentage of thymic Tcon and the proliferation of Tcon in MLN and blood were lower in the young resistants. These results suggest recipient age and associated disease stage as a variable to consider in BM-HSC transplantation for treating T1D.

  15. Growing City and Rapid Land Use Transition: Assessing Multiple Hazards and Risks in the Pokhara Valley, Nepal

    Directory of Open Access Journals (Sweden)

    Bhagawat Rimal


    Full Text Available Pokhara is one of the most naturally beautiful cities in the world with a unique geological setting. This important tourist city is under intense pressure from rapid urbanization and population growth. Multiple hazards and risks are rapidly increasing in Pokhara due to unsustainable land use practices, particularly the increase in built-up areas. This study examines the relationship among urbanization, land use/land cover dynamics and multiple hazard and risk analysis of the Pokhara valley from 1990 to 2013. We investigate some of the active hazards, such as floods, landslides, fire, sinkholes, land subsidence and earthquakes, and prepare an integrated multiple hazard risk map indicating the highly vulnerable zones. Land use and land cover maps from 1990 and 2013 from Landsat images (30 m resolution have been prepared and analyzed for the spatial dynamics of urbanization and the transition of land use and land cover. In the 23-year period, the built-up area more than doubled from 24.03 km² to 54.20 km². Although the landscape in the urban, peri-urban and rural areas appears to be fragmented, different drivers play pivotal roles in landscape change in these areas. The results provide substantial information for establishing innovative action plans for disaster risk management in the valley. Recommendations are made for the most suitable places for future urban expansion in the valley. This study is important for raising awareness among policy makers and other public officials to include multiple hazard risk mitigation in land use policies and plans. Establishing connections between urban expansions, escalating population growth and multiple hazards and risk assessment will also improve in modelling the latent impact of future catastrophes and emergency preparedness.

  16. Integrated care for older populations and its implementation facilitators and barriers: A rapid scoping review. (United States)

    Inform health system improvements by summarizing components of integrated care in older populations. Identify key implementation barriers and facilitators. A scoping review was undertaken for evidence from MEDLINE, the Cochrane Library, organizational websites and internet searches. Eligible publications included reviews, reports, individual studies and policy documents published from 2005 to February 2017. Initial eligible documents were reviews or reports concerning integrated care approaches in older/frail populations. Other documents were later sourced to identify and contextualize implementation issues. Study findings and implementation barriers and facilitators were charted and thematically synthesized. Thematic synthesis using 30 publications identified 8 important components for integrated care in elderly and frail populations: (i) care continuity/transitions; (ii) enabling policies/governance; (iii) shared values/goals; (iv) person-centred care; (v) multi-/inter-disciplinary services; (vi) effective communication; (vii) case management; (viii) needs assessments for care and discharge planning. Intervention outcomes and implementation issues (barriers or facilitators) tend to depend heavily on the context and programme objectives. Implementation issues in four main areas were observed: (i) Macro-level contextual factors; (ii) Miso-level system organization (funding, leadership, service structure and culture); (iii) Miso-level intervention organization (characteristics, resources and credibility) and (iv) Micro-level factors (shared values, engagement and communication). Improving integration in care requires many components. However, local barriers and facilitators need to be considered. Changes are expected to occur slowly and are more likely to be successful where elements of integrated care are well incorporated into local settings.

  17. An aerosol climatology for a rapidly growing arid region (southern Arizona): Major aerosol species and remotely sensed aerosol properties. (United States)

    Sorooshian, Armin; Wonaschütz, Anna; Jarjour, Elias G; Hashimoto, Bryce I; Schichtel, Bret A; Betterton, Eric A


    This study reports a comprehensive characterization of atmospheric aerosol particle properties in relation to meteorological and back trajectory data in the southern Arizona region, which includes two of the fastest growing metropolitan areas in the United States (Phoenix and Tucson). Multiple data sets (MODIS, AERONET, OMI/TOMS, MISR, GOCART, ground-based aerosol measurements) are used to examine monthly trends in aerosol composition, aerosol optical depth (AOD), and aerosol size. Fine soil, sulfate, and organics dominate PM2.5 mass in the region. Dust strongly influences the region between March and July owing to the dry and hot meteorological conditions and back trajectory patterns. Because monsoon precipitation begins typically in July, dust levels decrease, while AOD, sulfate, and organic aerosol reach their maximum levels because of summertime photochemistry and monsoon moisture. Evidence points to biogenic volatile organic compounds being a significant source of secondary organic aerosol in this region. Biomass burning also is shown to be a major contributor to the carbonaceous aerosol budget in the region, leading to enhanced organic and elemental carbon levels aloft at a sky-island site north of Tucson (Mt. Lemmon). Phoenix exhibits different monthly trends for aerosol components in comparison with the other sites owing to the strong influence of fossil carbon and anthropogenic dust. Trend analyses between 1988 and 2009 indicate that the strongest statistically significant trends are reductions in sulfate, elemental carbon, and organic carbon, and increases in fine soil during the spring (March-May) at select sites. These results can be explained by population growth, land-use changes, and improved source controls.

  19. Rapid torque development in older female fallers and nonfallers: a comparison across lower-extremity muscles. (United States)

    LaRoche, Dain P; Cremin, Kim A; Greenleaf, Brittnee; Croce, Ronald V


    The objective of this study was to compare reaction time, joint torque, rate of torque development, and magnitude of neuromuscular activation of lower-extremity muscles in elderly female fallers and nonfallers. Participants included 11, elderly, female fallers (71.3+/-5.4 years) and twelve nonfallers (71.3+/-6.2 years) who completed a fall risk questionnaire. Then, maximal, voluntary, isometric contractions of the knee and ankle muscles were performed in reaction to a visual cue to determine joint torque, rate of torque development, reaction time, and nervous activation of agonists and antagonists. Results indicated that significantly more fallers reported "dizziness upon rising", "use of balance altering medications", "stress or depression", "not enough sleep", "arthritis in lower body", "chronic pain in lower body", and "tiring easily while walking" (all Ptorque, rate of torque development and impulse) were lower in fallers than in nonfallers (Pmuscle groups, fallers demonstrated 19% lower peak torque and 29% longer motor time (P<0.05). In conclusion, comprehensive fall risk screening and prevention programs should address both neuromuscular and non-muscular factors, and, weakness of the ankle dorsiflexors and plantarflexors should be further studied as potential contributors to falls in older adults.

  20. An old doctor grows older. (United States)

    Spiro, Howard


    Abstract:An old man, I am convinced that aging is no disease, but a normal part of living, just like childhood. Society should provide for our inevitable decline rather than support research to postpone our dying. Retirement, now so arbitrary, defines when men and women are old, and so discards contributions from the elderly who want to work. As a physician, I am sure that many of us over 65 could help to assist the caregivers who have so little time. Ageism is part of the problem: medical students learn ageism in their early training, and that ageism is reinforced by later contact with the frail sick elderly who come to them for care. Aging-and death-have grown invisible to the young. But now that we elderly are so many and, thanks to good luck or the Creator's grace, so healthy and still so active, we need to exercise the power of our numbers. We have obtained many rights, like "early-bird suppers" and discounted bus tickets, but we need to talk more about our duties and even about our obligations to the young who will someday take our place.

  2. Rapid eye movement sleep behaviour disorder in young- and older-onset Parkinson disease: a questionnaire-based study. (United States)

    Mahale, R; Yadav, R; Pal, P K


    Rapid eye movement sleep behavior disorder (RBD) is common in Parkinson disease (PD). To determine the frequency of clinically probable RBD (cpRBD) in young-onset (21 to 40 years; OOPD) and characterize its pattern. A total of 156 patients with PD (YOPD-51, OOPD-105) were clinically examined and the presence of RBD was diagnosed using the minimal criteria for diagnosis of RBD (International Classification of Sleep Disorders, ICSD-1). RBD screening questionnaire based on the minimal criteria was used. The bed-partners were also interviewed with Mayo sleep questionnaire. Other scales included Unified Parkinson Disease Rating Scale part III (UPDRS III), Hoehn & Yahr stage, Mini Mental Status Examination, Pittsburgh Sleep Quality Index, Parkinson Disease Sleep Scale, Epworth Sleep Scale, Hamilton Anxiety Rating Scale and Hamilton Depression Rating Scale. cpRBD was diagnosed in 30 (19.2%) patients, majority being OOPD rather than YOPD (86.7% vs. 13.3%; P=0.01). The frequency of RBD was significantly higher (P=0.016) in OOPD (24.8%) compared to those with YOPD (7.8%). Most often (72.4%) RBD occurred after the onset of parkinsonian symptoms. RBD was independently associated with higher global PSQI scores, total ESS scores and total PDSS scores after adjusting for the effects of age, gender, Hoehn & Yahr stage and duration of illness. Patients with RBD were older with later-onset motor symptoms, a more advanced stage, poorer sleep quality, and more frequent daytime sleepiness. Older-onset PD had a higher frequency of RBD than young-onset PD. Copyright © 2014 Elsevier B.V. All rights reserved.

  4. Do teachers and students get the Ed-Tech products they need: The challenges of Ed-Tech procurement in a rapidly growing market

    Directory of Open Access Journals (Sweden)

    Jennifer Morrison


    Full Text Available Ed-tech courseware products to support teaching and learning are being developed and made available for acquisition by school districts at a rapid rate. In this growing market, developers and providers face challenges with making their products visible to customers, while school district stakeholders must grapple with “discovering” which products of the many available best address their instructional needs. The present study presents the experiences with and perceptions about the procurement process from 47 superintendents representing diverse school districts in the U. S. Results indicate that, while improvements are desired in many aspects of the procurement process, the superintendents, overall, believe that, once desired products are identified, they are generally able to acquire them. Difficulties lie in tighter budgets, discovering products that are potentially the best choices, and evaluating the effectiveness of the products selected as options. These findings are presented and interpreted in relation to five major “Action Points” in the procurement process, and also with regard to implications for evaluating how educational technology impacts K-12 instruction.

  5. In Vitro Comparison of Ertapenem, Meropenem, and Imipenem against Isolates of Rapidly Growing Mycobacteria and Nocardia by Use of Broth Microdilution and Etest. (United States)

    Brown-Elliott, Barbara A; Killingley, Jessica; Vasireddy, Sruthi; Bridge, Linda; Wallace, Richard J


    We compared the activities of the carbapenems ertapenem, meropenem, and imipenem against 180 isolates of rapidly growing mycobacteria (RGM) and 170 isolates of Nocardia using the Clinical and Laboratory Standards Institute (CLSI) guidelines. A subset of isolates was tested using the Etest. The rate of susceptibility to ertapenem and meropenem was limited and less than that to imipenem for the RGM. Analysis of major and minor discrepancies revealed that >90% of the isolates of Nocardia had higher MICs by the broth microdilution method than by Etest, in contrast to the lower broth microdilution MICs seen for >80% of the RGM. Imipenem remains the most active carbapenem against RGM, including Mycobacterium abscessus subsp. abscessus For Nocardia, imipenem was significantly more active only against Nocardia farcinica Although there may be utility in testing the activities of the newer carbapenems against Nocardia, their activities against the RGM should not be routinely tested. Testing by Etest is not recommended by the CLSI. Copyright © 2016, American Society for Microbiology. All Rights Reserved.

  6. Growing trend in older patients with severe injuries: mortality and mechanisms of injury between 1991 and 2010 at an inner city major trauma centre. (United States)

    Dinh, Michael M; Roncal, Susan; Byrne, Christopher M; Petchell, Jeffrey


    Elderly patients with major trauma are an increasingly important public health concern. The objective of the study was to describe the long term trend in patients aged 65 years and older with major trauma. A retrospective single centre trauma registry study conducted at an inner city Major Trauma Centre in Sydney. Data on patients aged 65 years or older with major trauma (Injury Severity Score greater than 15) presenting between 1991 and 2010 were extracted from the data registry. Demographic data, mechanism of injury, injury severity scores and outcomes were collected. Study outcomes were proportion of total major trauma volume due to patients aged 65 years and older, in hospital mortality and total beddays occupied per year. The proportion of major trauma volume due to older patients increased by 4.9% per year currently accounting for a third of major trauma volume. The proportion of major trauma in older patients due to falls has also increased. Standardised mortality rates have declined by 2.2% per year. There has been a disproportionate increase in the proportion of major trauma due to older patients at this institution over the past twenty years. If this trend continues, it is likely to have significant impacts on future hospital and rehabilitation resources. © 2012 The Authors.

  7. Evaluation of capillary and myofiber density in the pectoralis major muscles of rapidly growing, high-yield broiler chickens during increased heat stress. (United States)

    Joiner, K S; Hamlin, G A; Lien, A R J; Bilgili, S F


    Skeletal muscle development proceeds from early embryogenesis through marketing age in broiler chickens. While myofiber formation is essentially complete at hatching, myofiber hypertrophy can increase after hatch by assimilation of satellite cell nuclei into myofibers. As the diameter of the myofibers increases, capillary density peripheral to the myofiber is marginalized, limiting oxygen supply and subsequent diffusion into the myofiber, inducing microischemia. The superficial and deep pectoralis muscles constitute 25% of the total body weight in a market-age bird; thus compromise of those muscle groups can have profound economic impact on broiler production. We hypothesized that marginal capillary support relative to the hypertrophic myofibers increases the incidence of microischemia, especially in contemporary high-yield broilers under stressing conditions such as high environmental temperatures. We evaluated the following parameters in four different broiler strains at 39 and 53 days of age when reared under thermoneutral (20 to 25 C) versus hot (30 to 35 C) environmental conditions: capillary density, myofiber density and diameter, and degree of myodegeneration. Our data demonstrate that myofiber diameter significantly increased with age (P > or = 0.0001), while the absolute numbers of capillaries, blood vessels, and myofibers visible in five 400 x microscopic fields decreased (P > or = 0.0001). This is concomitant with marginalization of vascular support in rapidly growing myofibers. The myofiber diameter was significantly lower with hot environmental temperatures (P > or = 0.001); therefore, the absolute number of myofibers visible in five 400X microscopic fields was significantly higher. The incidence and subjective degree of myodegeneration characterized by loss of cross-striations, myocyte hyperrefractility, sarcoplasmic vacuolation, and nuclear pyknosis or loss also increased in hot conditions. Differences among strains were not observed.

  8. Point-of-use membrane filtration and hyperchlorination to prevent patient exposure to rapidly growing mycobacteria in the potable water supply of a skilled nursing facility. (United States)

    Williams, Margaret M; Chen, Tai-Ho; Keane, Tim; Toney, Nadege; Toney, Sean; Armbruster, Catherine R; Butler, W Ray; Arduino, Matthew J


    Healthcare-associated outbreaks and pseudo-outbreaks of rapidly growing mycobacteria (RGM) are frequently associated with contaminated tap water. A pseudo-outbreak of Mycobacterium chelonae-M. abscessus in patients undergoing bronchoscopy was identified by 2 acute care hospitals. RGM was identified in bronchoscopy specimens of 28 patients, 25 of whom resided in the same skilled nursing facility (SNF). An investigation ruled out bronchoscopy procedures, specimen collection, and scope reprocessing at the hospitals as sources of transmission. To identify the reservoir for RGM within the SNF and evaluate 2 water system treatments, hyperchlorination and point-of-use (POU) membrane filters, to reduce RGM. A comparative in situ study of 2 water system treatments to prevent RGM transmission. An SNF specializing in care of patients requiring ventilator support. RGM and heterotrophic plate count (HPC) bacteria were examined in facility water before and after hyperchlorination and in a subsequent 24-week assessment of filtered water by colony enumeration on Middlebrook and R2A media. Mycobacterium chelonae was consistently isolated from the SNF water supply. Hyperchlorination reduced RGM by 1.5 log(10) initially, but the population returned to original levels within 90 days. Concentration of HPC bacteria also decreased temporarily. RGM were reduced below detection level in filtered water, a 3-log(10) reduction. HPC bacteria were not recovered from newly installed filters, although low quantities were found in water from 2-week-old filters. POU membrane filters may be a feasible prevention measure for healthcare facilities to limit exposure of sensitive individuals to RGM in potable water systems.

  9. Movement trajectory smoothness is not associated with the endpoint accuracy of rapid multi-joint arm movements in young and older adults. (United States)

    Poston, Brach; Van Gemmert, Arend W A; Sharma, Siddharth; Chakrabarti, Somesh; Zavaremi, Shahrzad H; Stelmach, George


    The minimum variance theory proposes that motor commands are corrupted by signal-dependent noise and smooth trajectories with low noise levels are selected to minimize endpoint error and endpoint variability. The purpose of the study was to determine the contribution of trajectory smoothness to the endpoint accuracy and endpoint variability of rapid multi-joint arm movements. Young and older adults performed arm movements (4 blocks of 25 trials) as fast and as accurately as possible to a target with the right (dominant) arm. Endpoint accuracy and endpoint variability along with trajectory smoothness and error were quantified for each block of trials. Endpoint error and endpoint variance were greater in older adults compared with young adults, but decreased at a similar rate with practice for the two age groups. The greater endpoint error and endpoint variance exhibited by older adults were primarily due to impairments in movement extent control and not movement direction control. The normalized jerk was similar for the two age groups, but was not strongly associated with endpoint error or endpoint variance for either group. However, endpoint variance was strongly associated with endpoint error for both the young and older adults. Finally, trajectory error was similar for both groups and was weakly associated with endpoint error for the older adults. The findings are not consistent with the predictions of the minimum variance theory, but support and extend previous observations that movement trajectories and endpoints are planned independently.

  10. Sleep spindles and rapid eye movement sleep as predictors of next morning cognitive performance in healthy middle-aged and older participants. (United States)

    Lafortune, Marjolaine; Gagnon, Jean-François; Martin, Nicolas; Latreille, Véronique; Dubé, Jonathan; Bouchard, Maude; Bastien, Célyne; Carrier, Julie


    Spindles and slow waves are hallmarks of non-rapid eye movement sleep. Both these oscillations are markers of neuronal plasticity, and play a role in memory and cognition. Normal ageing is associated with spindle and slow wave decline and cognitive changes. The present study aimed to assess whether spindle and slow wave characteristics during a baseline night predict cognitive performance in healthy older adults the next morning. Specifically, we examined performance on tasks measuring selective and sustained visual attention, declarative verbal memory, working memory and verbal fluency. Fifty-eight healthy middle-aged and older adults (aged 50-91 years) without sleep disorders underwent baseline polysomnographic sleep recording followed by neuropsychological assessment the next morning. Spindles and slow waves were detected automatically on artefact-free non-rapid eye movement sleep electroencephalogram. All-night stage N2 spindle density (no./min) and mean frequency (Hz) and all-night non-rapid eye movement sleep slow wave density (no./min) and mean slope (μV/s) were analysed. Pearson's correlations were performed between spindles, slow waves, polysomnography and cognitive performance. Higher spindle density predicted better performance on verbal learning, visual attention and verbal fluency, whereas spindle frequency and slow wave density or slope predicted fewer cognitive performance variables. In addition, rapid eye movement sleep duration was associated with better verbal learning potential. These results suggest that spindle density is a marker of cognitive functioning in older adults and may reflect neuroanatomic integrity. Rapid eye movement sleep may be a marker of age-related changes in acetylcholine transmission, which plays a role in new information encoding. © 2013 European Sleep Research Society.

  11. Acceptability of an intelligent wireless sensor system for the rapid detection of health issues: findings among home-dwelling older adults and their informal caregivers. (United States)

    Cohen, Christine; Kampel, Thomas; Verloo, Henk


    Aging at home rather than in an institution is now considered the gold standard. Public health figures document an important demographic transition to an increasingly elderly society. At the same time, this is accompanied by the emergence of significant numbers of innovative technologies to help and support home-dwelling older adults in declining health who wish to remain at home. To explore the acceptability of intelligent wireless sensor system (IWSS) among home-dwelling older adults in rapidly detecting their health issues. Data were sourced from a pilot 3-month randomized clinical trial that involved 34 older patients in the experimental group (EG) using an IWSS to rapidly detect falls and other health issues at home. The effectiveness of the IWSS was assessed by comparing it to participants' functional and cognitive status, as measured both before and after the trial. The Resident Assessment Instrument for Home Care, Confusion Assessment Method, Cognitive Performance Scale, Geriatric Depression Scale, and Informed Questionnaire on Cognitive Decline in the Elderly were used for the assessments. Acceptability of the IWSS was explored at the end of the study. Both older adults and their informal caregivers considered the performance and usefulness of the IWSS intervention to be low to moderate. A majority of the participants were unsatisfied with its ease of use and found multiple obstacles in using and having an intention to use the IWSS. However, their informal caregivers were more satisfied with the program and gave higher scores for usefulness, ease of use, and intention to use IWSS technology. The IWSS displayed low-to-moderate acceptability among the older participants and their informal caregivers. We recommend improving and clarifying several components in the IWSS for the development of a design that is user-centered.

    The older person’s component of the population has increased rapidly in recent years due to developments in medicine, technology and other areas of life. Growing older implies a gradual decline in the physical, mental and social functioning of an individual. Older people consequently have to rely on others for assistance, and, in some instances, they are looked after in residential care facilities. These facilities should be sensitive to older person’s culture, religion, ethnic...

  17. Acceptability Among Community Healthcare Nurses of Intelligent Wireless Sensor-system Technology for the Rapid Detection of Health Issues in Home-dwelling Older Adults. (United States)

    Cohen, Christine; Kampel, Thomas; Verloo, Henk


    The effective care and support of community healthcare nurses (CHNs) contribute greatly to the healthy aging of older adults living at home. Integrating innovative technologies into CHNs' daily practice offers new opportunities and perspectives for early detection of health issues and interventions among home-dwelling older adults. To explore the perception of acceptability among CHNs of an intelligent wireless sensor system (IWSS) for use in daily practice for the detection of health issues in home-dwelling older adults receiving home healthcare. Descriptive and qualitative data were sourced from a pilot randomized controlled trial involving 17 CHNs using an IWSS in their daily practice to rapidly detect falls and other health issues in patients' homes. IWSS alerts indicating behavior changes were sent to CHNs. Their perceived usefulness (PU) and perceived ease of use (PEOU) were assessed. The acceptability of IWSS technology was explored using a questionnaire and focus group discussions. The PU and PEOU of the IWSS technology were low to moderate. A majority of the CHNs were dissatisfied with its performance and intrusiveness; they reported multiple obstacles in the usefulness and ease of use of the IWSS technology in daily practice. To improve the IWSS technology's low to moderate acceptability among CHNs, we recommend a more user-centered implementation strategy and an embedded model of nursing care.

    In Denmark, both influenza A(H1N1)pdm09 and influenza B co-circulated in the 2015/16 season. We estimated the vaccine effectiveness (VE) of the trivalent influenza vaccine in patients 65 years and older using the test-negative case-control design. The adjusted VE against influenza A(H1N1)pdm09...... was 35.0% (95% confidence interval (CI): 11.1-52.4) and against influenza B 4.1% (95% CI: -22.0 to 24.7). The majority of influenza A(H1N1)pdm09 circulating in 2015/16 belonged to the new genetic subgroup subclade 6B.1....

  1. Management of skeletal Class III malocclusion with unilateral crossbite on a growing patient using facemask-bonded rapid palatal expander and fixed appliances

    Tinnie Effendy


    Full Text Available Facemask (FM and bonded rapid palatal expander (RPE are part of growth modification treatments for correcting skeletal Class III pattern with retrognathic maxilla. This orthopaedic treatment is usually preceded by fixed appliances to achieve aesthetic dental alignment and improve interdigitation. This case report reviews treatment of Class III malocclusion with unilateral crossbite in a 12-year-old boy using FM and bonded RPE, followed by fixed appliances. Choice of FM and bonded RPE was in line with indication which was mild Class III malocclusion with retrognathic maxilla. Execution of treatment was made considering treatment biomechanics and patient cooperation. This orthopaedic treatment was followed by orthodontic treatment specifically aimed to correct unilateral crossbite, canine relationship yet to reach Class I, lower midline shift, as well as unintended dental consequences of using bonded RPE, namely posterior open bite and deepening curve of spee. Posttreatment facial profile and smile are more esthetic. Occlusion is significantly improved both functionally and aesthetically.

  2. Development of an in vitro Assay, Based on the BioFilm Ring Test®, for Rapid Profiling of Biofilm-Growing Bacteria. (United States)

    Di Domenico, Enea G; Toma, Luigi; Provot, Christian; Ascenzioni, Fiorentina; Sperduti, Isabella; Prignano, Grazia; Gallo, Maria T; Pimpinelli, Fulvia; Bordignon, Valentina; Bernardi, Thierry; Ensoli, Fabrizio


    Microbial biofilm represents a major virulence factor associated with chronic and recurrent infections. Pathogenic bacteria embedded in biofilms are highly resistant to environmental and chemical agents, including antibiotics and therefore difficult to eradicate. Thus, reliable tests to assess biofilm formation by bacterial strains as well as the impact of chemicals or antibiotics on biofilm formation represent desirable tools for a most effective therapeutic management and microbiological risk control. Current methods to evaluate biofilm formation are usually time-consuming, costly, and hardly applicable in the clinical setting. The aim of the present study was to develop and assess a simple and reliable in vitro procedure for the characterization of biofilm-producing bacterial strains for future clinical applications based on the BioFilm Ring Test® (BRT) technology. The procedure developed for clinical testing (cBRT) can provide an accurate and timely (5 h) measurement of biofilm formation for the most common pathogenic bacteria seen in clinical practice. The results gathered by the cBRT assay were in agreement with the traditional crystal violet (CV) staining test, according to the κ coefficient test (κ = 0.623). However, the cBRT assay showed higher levels of specificity (92.2%) and accuracy (88.1%) as compared to CV. The results indicate that this procedure offers an easy, rapid and robust assay to test microbial biofilm and a promising tool for clinical microbiology.

  5. Growing Pains

    CERN Multimedia

    Katarina Anthony


    Heat expands and cold contracts: it’s a simple thermodynamic rule. But when temperatures swing from 300 K to near-absolute zero, this rule can mean a contraction of more than 80 metres across the LHC’s 27-km-long cryogenic system. Keeping this growth in check are compensators (a.k.a. bellows), which shrink and stretch in response to thermodynamic changes. Leak tests and X-rays now underway in the tunnel have revealed that these “joints” might be suffering from growing pains…   This 25-μm weld crack is thought to be the cause of the helium leaks. Prior to the LS1 warm-up, CERN’s cryogenic experts knew of two points in the machine’s cryogenic distribution system that were leaking helium. Fortunately, these leaks were sufficiently small, confined to known sub-sectors of the cryogenic line and – with help from the vacuum team (TE-VSC) – could easily be compensated for. But as the machine warmed up f...

  8. Rapid eye movement sleep without atonia may help diagnose Lewy body disease in middle-aged and older patients with somatic symptom disorder. (United States)

    Munechika, Takayuki; Fujishiro, Hiroshige; Okuda, Masato; Iwamoto, Kunihiro; Torii, Youta; Iritani, Shuji; Ozaki, Norio


    Lewy body disease (LBD), including Parkinson's disease (PD) and dementia with Lewy bodies (DLB), is defined pathologically as degeneration in the central and peripheral nervous system associated with Lewy bodies. Somatic symptom disorder often predates the clinical diagnosis of PD and DLB. It is crucial to make an initial diagnosis of LBD in patients with psychiatric symptoms because administering psychotropic drugs often causes or exacerbates extrapyramidal signs. Given the close association between rapid eye movement (REM) sleep behaviour disorder and LBD, REM sleep without atonia on polysomnography may help to diagnose LBD in middle-aged and older patients with somatic symptom disorder. We reviewed the clinical profiles of five patients with an initial diagnosis of somatic symptom disorder who exhibited REM sleep without atonia on polysomnography. There were three men and two women, with a mean age of 68.4 years (range: 55.0-78.0 years). The mean Mini-Mental State Examination score was 26 (range: 22-30). Only two patients had a clinical history of dream-enacting behaviour and fulfilled the clinical criteria for REM sleep behaviour disorder, but clinical conditions in the other three patients corresponded to subclinical REM sleep behaviour disorder. Final clinical diagnoses were made as probable DLB in three patients; two patients did not meet the clinical criteria for PD or DLB. Neurological examinations revealed mild extrapyramidal signs in these two patients, and their scores on the motor component of the Unified Parkinson's Disease Rating Scale were 8 and 5 points, and their Mini-Mental State Examination scores were 30 points. Neither patient exhibited dream-enacting behaviour, but both had constipation. Cardiac 123 I-metaiodobenzylguanidine scintigraphy revealed mild increased washout rates. REM sleep without atonia may provide an opportunity to identify LBD in patients with somatic symptom disorder, even before they fulfil the clinical criteria for PD or

  9. Hyperlipidemia in older adults. (United States)

    Aslam, Farhan; Haque, Attiya; Lee, L Veronica; Foody, JoAnne


    Older adults carry the highest risk for coronary artery disease and the highest burden of atherosclerosis. Although most clinical trials of cholesterol-lowering therapy have not specifically targeted older persons, growing evidence supports treatment of elevated low-density lipoprotein cholesterol levels in older patients, especially those at high risk for coronary events. The decision to treat a high or high-normal cholesterol level in an elderly individual must be individualized based on chronologic and physiologic age. This article summarizes current data on lipid-lowering therapy in older adults and the management of hyperlipidemia in elderly patients.

  10. Identification of different subtypes of rapid growing Atypical Mycobacterium from water and soil sources: Using PCR-RFLP using hsp65 and rRNA 16s-23s genes. (United States)

    Varahram, Mohammad; Farnia, Parissa; Saif, Shima; Marashian, Mehran; Farnia, Poopak; Ghanavi, Jaladein; Velayati, Ali Akbar


    Nontuberculosis mycobacteria (NTM) are a diverse group of microorganisms that cause a variety of diseases in humans including skin, respiratory, and gastrointestinal tract infection. Generally, NTM are classified into two categories: rapid (7days). In this study, we aimed to investigate NTM frequency and prevalence in environmental samples. Additionally, we tried to identify various subtypes of isolated rapid growing mycobacteria (RGM). Through a prospective descriptive cross-sectional study, water and soil samples were gathered from four neighboring towns around Tehran, the capital of Iran, at different geographic directions. Every 100m(2) of the studied areas gave one sample containing 6g of soil in 3-5cm depth deposited in 50mL sterile water as sampling media. After digestion and decontamination, DNA from culture-positive specimens (RGM) were extracted using phenol-chloroform methods. Then the molecular identification of species and subspecies were performed using 16s-23s rRNA and hsp65 gene. In total, 341 RGM were found, out of which 322 (94.4%) were identified and 20 (5.8%) could not be identified. The most frequent RGM was, Mycobacterium fortuitum (72; 22%), Mycobacterium senegalense (58; 17.7%), Mycobacterium parafortuitum (44; 13.4%) and Mycobacterium conceptionense type 1 (24; 7.2%), and Mycobacterium cheloni type 1 (20; 6.0%). As shown in Table 1, M. fortuitum had more subtypes (8), and the frequency of subtypes 1 (27.7%), 4 (16.6%), and 5 (13.8%) were higher. Among subtypes of M. senegalense, subtype 1 had a higher frequency (70.4%) in comparison to subtype 2 (29.5%). M. cheloni had just one subtype. Our results showed M. fortuitum as the most prominent strain isolated from environmental samples. The frequency was similar in different places, irrespective of climatic variations. Availability of various subtypes of M. fortuitum might indicate a large circulation of this RGM in soil and water of Iranian territory. This high prevalence of M. fortuitum might

    From our recent survey of non-pigmented rapidly growing mycobacteria in the Parisian water system, three groups of isolates (taxons 1-3) corresponding to possible novel species were selected for taxonomic study. The three taxa each formed creamy white, rough colonies, had an optimal growth temperature of 30 °C, hydrolyzed Tween 80, were catalase-positive at 22 °C and expressed arylsulfatase activity. All three were susceptible to amikacin, ciprofloxacin and tigecycline. The three taxa produced specific sets of mycolic acids, including one family that has never previously been described, as determined by thin layer chromatography and nuclear magnetic resonance. The partial rpoB sequences (723 bp) showed 4-6 % divergence from each other and more than 5 % differences from the most similar species. Partial 16S rRNA gene sequences showed 99 % identity within each species. The most similar sequences for 16S rRNA genes (98-99 % identity over 1444-1461 bp) were found in the Mycobacterium fortuitum group, Mycobacterium septicum and Mycobacterium farcinogenes. The three taxa formed a new clade (bootstrap value, 99 %) on trees reconstructed from concatenated partial 16S rRNA, hsp65 and rpoB sequences. The above results led us to propose three novel species for the three groups of isolates, namely Mycobacterium lutetiense sp. nov. [type strain 071T=ParisRGMnew_1T (CIP 110656T=DSM 46713T)], Mycobacterium montmartrense sp. nov. [type strain 196T=ParisRGMnew_2T (CIP 110655T=DSM 46714T)] and Mycobacteriu marcueilense sp. nov. [type strain of 269T=ParisRGMnew_3T (CIP 110654T=DSM 46715T)].

  15. Partner Caregiving in Older Cohabiting Couples (United States)


    Objectives. Despite the rapidly increasing prevalence of cohabitation among older adults, the caregiving literature has exclusively focused on formally married individuals. Extending prior work on intra-couple care, this study contrasts frail cohabitors’ patterns of care receipt from a partner to that of frail spouses. Methods. Using nationally representative panel data from the Health and Retirement Study (2000, 2002, 2004, and 2006), we estimate random effects cross-sectional times series models predicting frail cohabitors’ likelihood of receiving partner care compared with their married counterparts’. Conditional on the receipt of intra-couple care, we also examine differences in marital and nonmarital partners’ caregiving hours and caregiving involvement relative to other helpers. Results. Net of sociodemographic, disability, and comorbidity factors, we find that cohabitors are less likely to receive partner care than married individuals. However, caregiving nonmarital partners provide as many hours of care as spouses while providing a substantially larger share of disabled respondents’ care than marital partners. Discussion. Cohabitation and marriage have distinct implications for older adults’ patterns of partner care receipt. This study adds weight to a growing body of research emphasizing the importance of accounting for older adults’ nontraditional union forms and of examining the ramifications of cohabitation for older adults’ well-being.

  17. Older adults need twice the federal poverty level to make ends meet in California. (United States)

    Wallace, Steven P; Padilla-Frausto, D Imelda; Smith, Susan E


    New calculations using the Elder Economic Security Standard (TM) Index (Elder Index) for California show that both singles and couples age 65 or older who rent need more than twice the amount established by the Federal Poverty Level (FPL) Guideline to meet basic living expenses. The gap is greater for elders who own their home and are paying a mortgage than for renters. The gap between basic expenses and the FPL is smaller for owners without a mortgage, but still exists. Housing and health care are the primary drivers of the high costs. This policy brief documents that the Elder Index provides a better measure of income adequacy than the FPL for older adults because it accounts for those costs at the county level. The growing number of public and nonprofit organizations using the Elder Index will aid the quality of planning and programs that improve income security for California's rapidly growing older population.

  18. Robotics to Enable Older Adults to Remain Living at Home

    Directory of Open Access Journals (Sweden)

    Alan J. Pearce


    Full Text Available Given the rapidly ageing population, interest is growing in robots to enable older people to remain living at home. We conducted a systematic review and critical evaluation of the scientific literature, from 1990 to the present, on the use of robots in aged care. The key research questions were as follows: (1 what is the range of robotic devices available to enable older people to remain mobile, independent, and safe? and, (2 what is the evidence demonstrating that robotic devices are effective in enabling independent living in community dwelling older people? Following database searches for relevant literature an initial yield of 161 articles was obtained. Titles and abstracts of articles were then reviewed by 2 independent people to determine suitability for inclusion. Forty-two articles met the criteria for question 1. Of these, 4 articles met the criteria for question 2. Results showed that robotics is currently available to assist older healthy people and people with disabilities to remain independent and to monitor their safety and social connectedness. Most studies were conducted in laboratories and hospital clinics. Currently limited evidence demonstrates that robots can be used to enable people to remain living at home, although this is an emerging smart technology that is rapidly evolving.

  19. The divide within: Older active ICT users position themselves against different 'Others'. (United States)

    Kania-Lundholm, Magdalena; Torres, Sandra


    Although research into older people's internet usage patterns is rapidly growing, their understandings of digital technologies, particularly in relation to how these are informed by their understandings of aging and old age, remain unexplored. This is the case because research on older active ICT users tends to regard old age as an empirically interesting part of the life-course as opposed to a theoretically profuse source of information about why and how older people engage with digital technologies. This article explores - through focus group interviews with 30 older adults (aged 66-89) - the ways in which the social position of old age is used by older active ICT users in order to make sense of how and why they engage with these technologies. In this article, positioning theory is used to shed light on how the older people interviewed positioned themselves as 'active older users' in the interviews. The analysis brings to the fore the divide that older people themselves create as they discursively position themselves against different types of ICT users and non-users (young and old) when describing how and why they engage with digital technologies.

  9. [Growing old differently: Transdisciplinary perspective]. (United States)

    Zimmermann, H-P


    Growing old differently: the phrase is intended to call something other to mind than merely the fact that images and forms of old age and aging have multiplied and diversified to an enormous extent. The suggestion put forward here is that otherness (as opposed to mere differences) should be positively reinforced. In other words, it is not just a matter of noting different forms of old age and aging but more than this, of seeking out opportunities for aging differently. In order to explore this, the article follows an older strand of theory, which has recently come to be frequently quoted in gerontology: the phenomenology of difference as reasoned analytically by Lévinas and Sartre and applied to gerontology by Améry and de Beauvoir. Here, opportunities for aging crucially depend on the way we look at it, how we observe and describe it and not least, how gerontology frames it. A distinction is made between two perspectives and their associated consequences for old age: alienation and alterity. Alienation means looking at old age above all as a disconcerting "other", as a perplexing, problematic deviation from the norm of vitality. Alterity, by contrast, refers to different options for living life in old age: options to be explored and opened up in contradistinction to cultural or academic alienation. Not least, the article appeals for diversity in scholarly approaches and for cross-disciplinary perspectives.

  13. Effects of photodynamic therapy on rapidly growing nontuberculous mycobacteria keratitis. (United States)

    Shih, Min-Hsiu; Huang, Fu-Chin


    The authors investigated the antimicrobial effect of methylene blue (MB)-mediated photodynamic therapy (PDT) on Mycobacterium fortuitum keratitis. In the in vitro study, the mycobacterial suspension and colonies were treated with the following: no MB, no light (normal control); MB and no light (dye control); light and no MB (light control); MB and light (PDT). Morphologic characteristics were examined by transmission electron microscopy. The bactericidal effects of combined PDT and antibiotic therapy (ciprofloxacin, moxifloxacin, and amikacin) were determined using the broth microdilution technique. Twenty-one rabbits with Mycobacterium keratitis were randomly divided into three groups (no treatment, topical amikacin treatment, and PDT combined with amikacin treatment). The clinical features of keratitis were scored and graded before treatment and before euthanatization. The diseased corneas were trephined for quantitative bacteriologic analysis to determine the antibacterial efficacy of the treatment. In the in vitro tests, the bacterial count had a 2-log reduction immediately after PDT treatment at 100 J/cm(2) with 10(-3)% MB. After PDT at 100 J/cm(2) with 10(-2)% MB, almost no viable bacteria were detected. PDT had a synergistic antimicrobial effect in combination with antibiotics. The phototoxicity occurred in the cytoplasm first and then disrupted the mycobacterial cell walls by lysis. In the rabbit keratitis model, combined PDT resulted in significantly less bacterial burden (P PDT against Mycobacterium fortuitum. PDT could be a potential alternative treatment for nontuberculous mycobacterial corneal infections.

  14. Neuropsychology of music – a rapidly growing branch of psychology

    Directory of Open Access Journals (Sweden)

    Katarina Habe


    Full Text Available Relationship between brain and music is of interest to musicians, psychologists and neuroscientists. In recent years no other area of psychology of music has seen as much advancement as neuropsychology of music. The aim of the article is to present some main issues in the neuropsychology of music abroad and in Slovenia, to classify research studies into larger categories and to predict the future development of this field.There are different levels of inquiry into the neuropsychology of music: (1 the analysis of normal and abnormal psychological and physiological functions to determine the principles and modes by which the human brain processes, codifies, stores, and produces music, and (2 a description of the clinical deficits in music perception or performance resulting from localized or diffuse damage to the nervous system. Main topics that occupy neuropsychology of music are neuropsychological models of musical processing, functional imaging of musical perception and cognition, and the use of music as a therapeutic and clinical tool. Although some important studies have already been conducted since the year 2003, in Slovenia we faced a "formal" turning point in acknowledging the importance of the connection between music, mind and brain with the Sinapsa's Week of the brain 2009 under the title Brain and music.

  18. Growing unculturable bacteria. (United States)

    Stewart, Eric J


    The bacteria that can be grown in the laboratory are only a small fraction of the total diversity that exists in nature. At all levels of bacterial phylogeny, uncultured clades that do not grow on standard media are playing critical roles in cycling carbon, nitrogen, and other elements, synthesizing novel natural products, and impacting the surrounding organisms and environment. While molecular techniques, such as metagenomic sequencing, can provide some information independent of our ability to culture these organisms, it is essentially impossible to learn new gene and pathway functions from pure sequence data. A true understanding of the physiology of these bacteria and their roles in ecology, host health, and natural product production requires their cultivation in the laboratory. Recent advances in growing these species include coculture with other bacteria, recreating the environment in the laboratory, and combining these approaches with microcultivation technology to increase throughput and access rare species. These studies are unraveling the molecular mechanisms of unculturability and are identifying growth factors that promote the growth of previously unculturable organisms. This minireview summarizes the recent discoveries in this area and discusses the potential future of the field.

  1. Factors Influencing Weaning Older Adults From Mechanical Ventilation: An Integrative Review. (United States)

    Stieff, Karen V; Lim, Fidelindo; Chen, Leon

    This study aim was to describe the influences that affect weaning from mechanical ventilation among older adults in the intensive care unit (ICU). Adults older than 65 years comprised only 14.5% of the US population in 2014; however, they accounted up to 45% of all ICU admissions. As this population grows, the number of ICU admissions is expected to increase. One of the most common procedures for hospitalized adults 75 years and older is mechanical ventilation. An integrative review methodology was applied to analyze and synthesize primary research reports. A search for the articles was performed using the PubMed and Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases; using the keywords and Boolean operators "older adults," "weaning," "mechanical ventilation," and intensive care unit. Although physiologic changes that occur with aging place older adults at higher risk for respiratory complications and mortality, there are many factors, other than chronological age, that can determine a patient's ability to be successfully weaned from mechanical ventilation. Of the 6 studies reviewed, all identified various predictors of weaning outcome, which included maximal inspiratory pressure, rapid shallow breathing index, fluid balance, comorbidity burden, severity of illness, emphysematous changes, and low serum albumin. Age, in and of itself, is not a predictor of weaning from mechanical ventilation. More studies are needed to describe the influences affecting weaning older adults from mechanical ventilation.

  2. Employees older than 50 on Croatian labour market – need for a new approach

    Directory of Open Access Journals (Sweden)

    Srecko Goic


    Full Text Available Croatia has reached demographic maturity, with ever lower cohorts of youngers (and younger labour force numbers, longer life expectations, and rapidly growing share of older population. In such situation, working population older than 50 becomes more and more significant, not only by number, but also as an important pool of knowledge and experiences. 28,36% of total employed in Croatia in 2014 were 50+ years old. That same year (2014 27,7% of total unemployed in Croatia were 50+ years old. The share of persons 50+ in total number of unemployed grew to 29,6% in 2015, and 31,7% in 2016. Long duration of unemployment is especially accentuated among persons older than 50: in 2016 older persons made 41,91% among those with unemployment duration between 2 and 3 years, 44,00% among those with unemployment duration between 4 and 5 years, 53,23% among those with unemployment duration between 6 and 8 years, and even 70,04% among those with unemployment duration over 8 years. Although Croatian governments for almost quarter of century were devising different “active labour market policies” directed to older persons, their results are questionable. With growing problems to acquire and retain necessary workforce in Croatian enterprises, there is obviously strong need to develop new approach (es towards people older than 50. This paper is trying to shed new light on this problem and offer new ideas in the field of labour market policies, and human resources management oriented towards older employees in Croatia. The Croatian example (changes, problems, and experiences may be of interest to other, particularly European, countries in a similar situation.

  3. Nurses' attitudes towards older people and working with older patients: an explanatory model. (United States)

    Liu, Yun-E; Norman, Ian J; While, Alison E


    To establish an explanatory model of registered nurses' attitudes towards older people and working with older patients. Increasing demands for health-care from an ageing population will require a higher proportion of nurses who have positive attitudes towards older people and like working with older patients. A convenience sample of registered nurses (n = 579; 79.3% response rate) attending continuing professional education courses within a large university in London was surveyed from October to December 2011. Registered nurses expressed positive attitudes towards older people and 89.7% reported positive attitudes towards working with older patients. The variables of self-ageing anxiety, attitudes towards health-care resource allocation, knowledge of ageing, ethnic group, job title, attitudes towards older patients and interaction between ethnic group and attitudes towards working with older patients explained 42.6% of the variance in attitudes towards older people. Factors, including attitudes towards older people, self-ageing anxiety, commitment to nursing, attitudes towards health-care resources allocation among older people and clinical specialty explained 16.7-34.3% of the variance in attitudes towards older patients. The models identified several related factors that may help in the selection and management of nurses for caring older people. Our findings highlight the importance of investing in continuing education related to gerontological nursing and the ageing process so that there is a growing pool of registered nurses who wish to care for older patients. © 2014 John Wiley & Sons Ltd.

  5. Growing for different ends. (United States)

    Catts, Oron; Zurr, Ionat


    Tissue engineering and regenerative biology are usually discussed in relation to biomedical research and applications. However, hand in hand with developments of this field in the biomedical context, other approaches and uses for non-medical ends have been explored. There is a growing interest in exploring spin off tissue engineering and regenerative biology technologies in areas such as consumer products, art and design. This paper outlines developments regarding in vitro meat and leather, actuators and bio-mechanic interfaces, speculative design and contemporary artistic practices. The authors draw on their extensive experience of using tissue engineering for non-medical ends to speculate about what lead to these applications and their possible future development and uses. Avoiding utopian and dystopian postures and using the notion of the contestable, this paper also mentions some philosophical and ethical consideration stemming from the use of non-medical approaches to tissue constructs.

    Full Text Available Growing evidence supports the use of physical training interventions to improve both physical and cognitive performances in healthy older adults. Few studies have examined the impact of aerobic exercise on Stroop task performance, a measure of executive functions. In the current 3-month aerobic training study, 50 older adults (mean age = 67.96 ± 6.25 years were randomly assigned to either a three-month physical training group or to a control group (waiting list. Training sessions were 3 times per week for 60 minutes. All participants completed pre- and post-test measures of cognitive performance using the modified Stroop task and physical performance (Rockport one-mile test. Compared to controls, the training group showed significant improvements in physical capacity (P<0.001 and enhanced Stroop performance, but only in the inhibition/switching condition (P<0.03. Furthermore, the increase in aerobic capacity induced by the training regimen correlated negatively with reaction time in the inhibition/switching condition of the Stroop task at posttest (r=−0.538; P=0.007. Importantly, the reported gains in cognitive performance were observed after only three months of physical training. Taken together, the results suggest that even short-term physical interventions can enhance older adults’ executive functions.

    Full Text Available Research studies in the area of biotechnologies in fruit growing started at the Agricultural Institute Osijek in 2006 with the establishment of the first experimental in vitro laboratory for micropropagation. The laboratory started an active research related to the Project "Biotechnological methods in fruit tree identification, selection and propagation" Project is part of program "Preservation and revitalization of grape and fruit autochthonous cultivars". The goal of this research is to determine genetic differences between autochthonous and introduced cultivars of cherry as well as cultivars and types of sour cherry, to find and optimize a method for fast recovery of clonal material. A great number of cherry cultivars and types within the population of cv. Oblacinska sour cherry exists in Croatia. A survey with the purpose of selecting autochthonous cultivars for further selection has been done in previous research. Differences have been found in a number of important agronomic traits within the populations of cv. Oblačinska sour cherry. Autochthonous cherry cultivars are suspected to be synonyms of known old cultivars which were introduced randomly and have been naturalized under a local name. Identification and description of cultivars and types of fruits is based on special visible properties which were measurable or notable. In this approach difficulties arise from the effect of non-genetic factors on expression of certain traits. Genetic-physiological problem of S allele autoincompatibility exists within cherry cultivars. Therefore it is necessary to put different cultivars in the plantation to pollinate each other. Apart form the fast and certain sort identification independent of environmental factors, biotechnological methods based on PCR enable faster virus detection compared with classical serologic methods and indexing and cover a wider range of plant pathogens including those undetectable by other methods.

  8. Growing Galaxies Gently (United States)


    New observations from ESO's Very Large Telescope have, for the first time, provided direct evidence that young galaxies can grow by sucking in the cool gas around them and using it as fuel for the formation of many new stars. In the first few billion years after the Big Bang the mass of a typical galaxy increased dramatically and understanding why this happened is one of the hottest problems in modern astrophysics. The results appear in the 14 October issue of the journal Nature. The first galaxies formed well before the Universe was one billion years old and were much smaller than the giant systems - including the Milky Way - that we see today. So somehow the average galaxy size has increased as the Universe has evolved. Galaxies often collide and then merge to form larger systems and this process is certainly an important growth mechanism. However, an additional, gentler way has been proposed. A European team of astronomers has used ESO's Very Large Telescope to test this very different idea - that young galaxies can also grow by sucking in cool streams of the hydrogen and helium gas that filled the early Universe and forming new stars from this primitive material. Just as a commercial company can expand either by merging with other companies, or by hiring more staff, young galaxies could perhaps also grow in two different ways - by merging with other galaxies or by accreting material. The team leader, Giovanni Cresci (Osservatorio Astrofisico di Arcetri) says: "The new results from the VLT are the first direct evidence that the accretion of pristine gas really happened and was enough to fuel vigorous star formation and the growth of massive galaxies in the young Universe." The discovery will have a major impact on our understanding of the evolution of the Universe from the Big Bang to the present day. Theories of galaxy formation and evolution may have to be re-written. The group began by selecting three very distant galaxies to see if they could find evidence

  9. Coaching Older

    Directory of Open Access Journals (Sweden)

    Stacey Masters


    Full Text Available BackgroundFrail older people who are considering movement into residential aged care or returning home following a hospital admission often face complex and difficult decisions. Despite research interest in this area, a recent Cochrane review was unable to identify any studies of interventions to support decision-making in this group that met the experimental or quasi-experimental study design criteria. AimsThis study tests the impact of a multi-component coaching intervention on the quality of preparation for care transitions, targeted to older adults and informal carers. In addition, the study assesses the impact of investing specialist geriatric resources into consultations with families in an intermediate care setting where decisions about future care needs are being made. Method This study was a randomised controlled trial of 230 older adults admitted to intermediate care in Australia. Masked assessment at 3 and 12 months examined physical functioning, health-related quality of life and utilisation of health and aged care resources. A geriatrician and specialist nurse delivered a coaching intervention to both the older person and their carer/family. Components of the intervention included provision of a Question Prompt List prior to meeting with a geriatrician (to clarify medical conditions and treatments, medications, ‘red flags’, end of life decisions and options for future health care and a follow-up meeting with a nurse who remained in telephone contact. Participants received a printed summary and an audio recording of the meeting with the geriatrician.ConclusionThe costs and outcomes of the intervention are compared with usual care.

  10. Depressive Symptoms Affect Working Memory in Healthy Older Adult Hispanics. (United States)

    Salazar-Villanea, Monica; Liebmann, Edward; Garnier-Villarreal, Mauricio; Montenegro-Montenegro, Esteban; Johnson, David K


    Low and middle income nations will experience an unprecedented growth of the elderly population and subsequent increase in age-related neurological disorders. Worldwide prevalence and incidence of all-types of neurological disorders with serious mental health complications will increase with life expectancy across the globe. One-in- ten individuals over 75 has at least moderate cognitive impairment. Prevalence of cognitive impairment doubles every 5 years thereafter. Latin America's population of older adult's 65 years and older is growing rapidly, yet little is known about cognitive aging among healthy older Latinos. Clinically significant depressive symptomatology is common among community-dwelling older adults and is associated with deficits across multiple cognitive domains, however much of the literature has not modeled the unique effects of depression distinct from negative and low positive affect. Our objective was to understand how mental health affects cognitive health in healthy aging Latinos. The present study used confirmatory factor analysis (CFA) and structural equation modeling (SEM) to examine the relative effects of Negative Affect, Positive Affect and Geriatric Depression on Verbal Memory, Verbal Reasoning, Processing Speed, and Working Memory in healthy aging Latinos. Data was collected from a sample of healthy community dwelling older adults living in San Jose, Costa Rica. Modeling of latent variables attenuated error and improved measurement reliability of cognition, affect, and depression variables. Costa Ricans enjoy a notoriety for being much happier than US citizens and are renowned as one of the happiest nations in the world in global surveys. This was born out in these data. Costa Rican affective profiles differed substantively from US profiles. Levels of negative affect and depression were similar to US samples, but their levels of positive affect were much higher. Cognitive performance of these Costa Rican older adults was similar to US

  11. Older adult education in Lithuanian ageing society

    Directory of Open Access Journals (Sweden)

    Zemaitaityte I.


    Full Text Available The article analyzes the phenomenon of the demographic ageing of the population and educational opportunities for older adults in Lithuania. Ageing population is a natural outcome of demographic evolution of society. However, a growing number of older people in Lithuania as well as in other European countries requires continuous revision of societal resources in social security, economics, education, health care areas and their adjustment to the new demands. Though current discussion in Lithuania highlights the inclusion of older adults into active social life through educational activities, the studies in diverse areas show that a small number of older people take part in lifelong learning. For this reason and in the attempt to make older people feel satisfaction with life it is necessary to encourage their activity, to promote their social roles, to give them opportunities to take up voluntary tasks, educational and cultural functions and study new subjects.

  12. Mobilizing cross-sector community partnerships to address the needs of criminal justice-involved older adults: a framework for action. (United States)

    Metzger, Lia; Ahalt, Cyrus; Kushel, Margot; Riker, Alissa; Williams, Brie


    Purpose The rapidly increasing number of older adults cycling through local criminal justice systems (jails, probation, and parole) suggests a need for greater collaboration among a diverse group of local stakeholders including professionals from healthcare delivery, public health, and criminal justice and directly affected individuals, their families, and advocates. The purpose of this paper is to develop a framework that local communities can use to understand and begin to address the needs of criminal justice-involved older adults. Design/methodology/approach The framework included solicit input from community stakeholders to identify pressing challenges facing criminal justice-involved older adults, conduct needs assessments of criminal justice-involved older adults and professionals working with them; implement quick-response interventions based on needs assessments; share findings with community stakeholders and generate public feedback; engage interdisciplinary group to develop an action plan to optimize services. Findings A five-step framework for creating an interdisciplinary community response is an effective approach to action planning and broad stakeholder engagement on behalf of older adults cycling through the criminal justice system. Originality/value This study proposes the Criminal Justice Involved Older Adults in Need of Treatment Initiative Framework for establishing an interdisciplinary community response to the growing population of medically and socially vulnerable criminal justice-involved older adults.

    Mo-Yeol Kang

    Full Text Available The aim of this research was to investigate the association between job loss and the development of stroke or cardiovascular disease among middle-aged to older individuals in Korea. We also examined how this relationship was modified by gender and the nature of the job loss.This study used samples from the first- to fourth-wave datasets from the Korean Longitudinal Study of Aging (KLoSA, which were collected in 2006, 2008, 2010, and 2012. The study collected data from a total of 10,254 subjects aged ≥ 45 years at baseline. After applying exclusion criteria, the final sample size for analysis consisted of 4,000 individuals. Information about employment status, development of stroke or cardiovascular disease, and covariates (age, income level, and behavioral factors was obtained. Cox proportional hazards models were used to evaluate the association between voluntary/involuntary job loss and the development of stroke or cardiovascular disease. We performed these analyses separately according to disease, gender, and the nature of the job loss.Involuntary job loss significantly increased the risk of stroke or cardiovascular disease among males (adjusted hazard ratio [HR]  = 3.560, 95% confidence interval [CI]  = 2.055-6.168. Voluntary retirement also increased the risk of cardiovascular disease or stroke among males (adjusted HR = 2.879, 95% CI = 1.533-5.409. Job loss was more closely associated with stroke than with cardiovascular disease (stroke, adjusted HR = 6.208, 95% CI = 2.417-15.943; cardiovascular disease, adjusted HR = 2.768, 95% CI = 1.402-5.465.Our findings suggest that both voluntary retirement and involuntary job loss increase the risk for stroke or cardiovascular disease in middle-aged to older individuals, especially males.

  5. A Systematic Review of Culturally Specific Interventions to Increase Physical Activity for Older Asian Americans. (United States)

    Katigbak, Carina; Flaherty, Erin; Chao, Ying-Yu; Nguyen, Tam; Cheung, Daphne; Yiu-Cho Kwan, Rick


    Physical activity (PA) is a significant modifiable risk factor for cardiovascular disease. For older adults, engaging in PA is shown to improve cardiac status, reduce cognitive, and functional decline, and improve overall quality of life. However, only 17% of Asian American adults meet the 2008 federal recommended guidelines for aerobic and muscle strengthening activity; and there is a paucity of data reporting on older Asian Americans - a rapidly growing, underserved group. While data pertaining to Asian Americans is frequently reported at the aggregate level, this masks differences (eg, language, culture, income) among Asian ethnic subgroups that may impact health behaviors. The purpose of this review was to identify intervention, and cultural adaptation strategies in studies promoting PA for older Asian Americans. A comprehensive literature search was performed to identify interventions published between 1996-2016 focused on improving PA among older Asian Americans (> 60 years old). Data were abstracted to examine intervention study designs, cultural adaptation strategies, theoretical frameworks, and physical activity measures. Nine studies met the reviewâs inclusion criteria. Community-based recruitment approaches were widely used, and all studies employed cultural adaptation to varying degrees. Most studies reported improvements in PA outcomes, focused on Chinese Americans, and relied on self-reports of PA, while few aimed to increase PA using a multi-component approach. Future studies would benefit from larger sample sizes, a wider representation of Asian ethnic subgroups, and concentrated efforts to implement deep level adaptations that may increase the salience and sustainability of these interventions.

  6. Sexual and reproductive health and rights of older men and women: addressing a policy blind spot. (United States)

    Aboderin, Isabella


    Global debate on required policy responses to issues of older persons has intensified over the past 15 years, fuelled by a growing awareness of the rapid ageing of populations. Health has been a central focus, but scrutiny of global policies, human rights instruments and reports reveals that just as older people are excluded from sexual and reproductive health and rights agendas, so are issues of sexual and reproductive health and rights wholly marginal to current agendas focused on older people. A critical question is whether the policy lacuna reflects a dearth of research evidence or a faulty translation of existing knowledge. A reading of the current research landscape and literature, summarised in this paper, strongly suggests it is the former. To be sure, sexuality in old age is a burgeoning field of scientific inquiry. What the existing knowledge and discourse fail to provide is an engagement with, and elucidation of, the broader sexual and reproductive health and rights agenda as it relates to older persons. A concerted research effort is needed to provide a basis for developing policy guidance and for pinpointing essential indicators and establishing necessary data systems to enable a routine tracking of progress.

When A{sub k} grows more slowly than linearly with k, the number of nodes with k links, N{sub k}(t), decays faster than a power law in k, while for A{sub k} growing faster than linearly in k, a single node emerges which connects to nearly all other nodes. When A{sub k} is asymptotically linear, N{sub k}(t){similar_to}tk{sup {minus}{nu}}, with {nu} dependent on details of the attachment probability, but in the range 2{lt}{nu}{lt}{infinity}. The combined age and degree distribution of nodes shows that old nodes typically have a large degree. There is also a significant correlation in the degrees of neighboring nodes, so that nodes of similar degree are more likely to be connected. The size distributions of the in and out components of the network with respect to a given node{emdash}namely, its {open_quotes}descendants{close_quotes} and {open_quotes}ancestors{close_quotes}{emdash}are also determined. The in component exhibits a robust s{sup {minus}2} power-law tail, where s is the component size. The out component has a typical size of order lnt, and it provides basic insights into the genealogy of the network.

    Hadley Strout, Emily; Fox, Leah; Castro, Alejandro; Haroun, Pishoy; Leavitt, Blake; Ross, Cordelia; Sayan, Mutlay; Delaney, Thomas; Platzer, Alyson; Hutchins, Jeanne; Carney, Jan K


    Aging often leads to decreased independence and mobility, which can be detrimental to health and well-being. The growing population of older adults will create a greater need for reliable transportation. Explore whether and how lack of transportation has compromised areas of daily lives in older adults. 1221 surveys with 36 questions assessing transportation access, usage, and impact on activities were distributed to Chittenden County, Vermont older adults; 252 met criteria for analysis. Older adults reported overwhelming difficulty getting to activities considered important, with 69 % of participants delaying medical appointments due to transportation barriers. Although family and friends represent a primary method of transportation, older adults reported difficulty asking them for help. Lack of accessible transportation leads to missed healthcare appointments and social isolation, which may have detrimental effects on older adults' quality of life. Many older adults face significant transportation challenges that negatively affect their health and well-being.

  14. Medication prescribing in frail older people. (United States)

    Hubbard, Ruth E; O'Mahony, M Sinead; Woodhouse, Kenneth W


    While some people remain fit and active as they grow older, others experience complex problems: disease, dependency and disability. Frailty is a term used to describe this latter group, capturing differences in health status among older people. Many frail older people have multiple chronic co-morbidities and functional impairments and, according to guidelines for the management of individual conditions, should be prescribed long lists of medications. However, older people (particularly those who are frail) are often excluded from drug trials, and treatment decisions are therefore based on evidence extrapolated from more robust patient groups with fewer physiological deficits. The risk of adverse drug reactions (ADRs) increases with increasing patient frailty, and polypharmacy has negative consequences above and beyond the risks of individual drugs. Increasing numbers of medications are associated with a higher likelihood of non-adherence and a significantly greater risk of ADRs. Older people taking five or more medications are at higher risk of delirium and falls, independent of medication indications. This is a short review of the different approaches to defining and measuring frailty. We summarise the factors contributing to ADRs in frail older people and describe the pharmacokinetic and pharmacodynamics changes associated with ageing and frailty. By considering goals of care for frail older people, we explore how the appropriateness of medication prescribing for older people could be improved. Since all physicians are likely to provide care for this group of vulnerable patients, understanding the concept of frailty may help to optimise medication prescribing for older people. The incorporation of frailty measures into future clinical studies of drug effects and pharmacokinetics is important if we are to improve medication use and guide drug doses for fit and frail older people.

  16. Active social participation and mortality risk among older people in Japan: results from a nationally representative sample. (United States)

    Minagawa, Yuka; Saito, Yasuhiko


    A large literature suggests that active social participation contributes to the well-being of older people. Japan provides a compelling context to test this hypothesis due to its rapidly growing elderly population and the phenomenal health of the population. Using the Nihon University Japanese Longitudinal Study of Aging, this study examines how social participation, measured by group membership, is related to the risk of overall mortality among Japanese elders aged 65 and older. Results from Cox proportional hazards models show that group affiliation confers advantages against mortality risk, even after controlling for sociodemographic characteristics, physical health measures, and family relationship variables. In particular, activities geared more toward self-development, such as postretirement employment and lifelong learning, are strongly associated with lower levels of mortality. Findings suggest that continued social participation at advanced ages produces positive health consequences, highlighting the importance of active aging in achieving successful aging in the Japanese context. © The Author(s) 2014.

  17. Growing random networks with fitness


    Ergun, G.; Rodgers, GJ


    Three models of growing random networks with fitness dependent growth rates are analysed using the rate equations for the distribution of their connectivities. In the first model (A), a network is built by connecting incoming nodes to nodes of connectivity $k$ and random additive fitness $\\eta$, with rate $(k-1)+ \\eta $. For $\\eta >0$ we find the connectivity distribution is power law with exponent $\\gamma=+2$. In the second model (B), the network is built by connecting nodes to nodes of conn...

    Vicente, P. de; Lopes, I.


    Research on mobile technology adoption has focused predominantly on young adults, and little attention has been paid to older people. But with rapidly aging populations in most developed countries, and evidence from many studies that older adults are as capable of adopting and using mobile technology as everybody else, the academic, business and technology industry worlds are devoting more attention to this group. Research has already demonstrated that older people differ from young people in...

  19. Position of the Academy of Nutrition and Dietetics: food and nutrition for older adults: promoting health and wellness. (United States)

    Bernstein, Melissa; Munoz, Nancy


    It is the position of the Academy of Nutrition and Dietetics that all Americans aged 60 years and older receive appropriate nutrition care; have access to coordinated, comprehensive food and nutrition services; and receive the benefits of ongoing research to identify the most effective food and nutrition programs, interventions, and therapies. Health, physiologic, and functional changes associated with the aging process can influence nutrition needs and nutrient intake. The practice of nutrition for older adults is no longer limited to those who are frail, malnourished, and ill. The population of adults older than age 60 years includes many individuals who are living healthy, vital lives with a variety of nutrition-related circumstances and environments. Access and availability of wholesome, nutritious food is essential to ensure successful aging and well-being for the rapidly growing, heterogeneous, multiracial, and ethnic population of older adults. To ensure successful aging and minimize the effects of disease and disability, a wide range of flexible dietary recommendations, culturally sensitive food and nutrition services, physical activities, and supportive care tailored to older adults are necessary. National, state, and local strategies that promote access to coordinated food and nutrition services are essential to maintain independence, functional ability, disease management, and quality of life. Those working with older adults must be proactive in demonstrating the value of comprehensive food and nutrition services. To meet the needs of all older adults, registered dietitians and dietetic technicians, registered, must widen their scope of practice to include prevention, treatment, and maintenance of health and quality of life into old age.

Objective: The aim of this study was to reach a new understanding of home as a health promotion setting for older persons. Study design: The method used was a literature reflection and analysis......The number and the proportion of older persons is growing in the Nordic Countries. The growth in the older population has a clear impact on the care system for older persons. One trend is to prioritise home care instead of care in institutions. Another trend is to emphasise preventive and health...... promotion care. As official guidelines in the Nordic countries state that home is the best place to grow old, it is essential that older persons keep their health and functional capacity in order to be able to live at home for as long as possible. As current policy emphasises living at home, home care...

  1. Neural-like growing networks (United States)

    Yashchenko, Vitaliy A.


    On the basis of the analysis of scientific ideas reflecting the law in the structure and functioning the biological structures of a brain, and analysis and synthesis of knowledge, developed by various directions in Computer Science, also there were developed the bases of the theory of a new class neural-like growing networks, not having the analogue in world practice. In a base of neural-like growing networks the synthesis of knowledge developed by classical theories - semantic and neural of networks is. The first of them enable to form sense, as objects and connections between them in accordance with construction of the network. With thus each sense gets a separate a component of a network as top, connected to other tops. In common it quite corresponds to structure reflected in a brain, where each obvious concept is presented by certain structure and has designating symbol. Secondly, this network gets increased semantic clearness at the expense owing to formation not only connections between neural by elements, but also themselves of elements as such, i.e. here has a place not simply construction of a network by accommodation sense structures in environment neural of elements, and purely creation of most this environment, as of an equivalent of environment of memory. Thus neural-like growing networks are represented by the convenient apparatus for modeling of mechanisms of teleological thinking, as a fulfillment of certain psychophysiological of functions.

    - Myopia is the eye disorder with the most rapid increase in prevalence worldwide. It develops in childhood, with a peak incidence between the ages of 13 to 15 years. - Especially high myopia, i.e. a refractive error of -6 diopters or more, increases the risk of permanent visual impairment during

  3. Habitual attention in older and young adults. (United States)

    Jiang, Yuhong V; Koutstaal, Wilma; Twedell, Emily L


    Age-related decline is pervasive in tasks that require explicit learning and memory, but such reduced function is not universally observed in tasks involving incidental learning. It is unknown if habitual attention, involving incidental probabilistic learning, is preserved in older adults. Previous research on habitual attention investigated contextual cuing in young and older adults, yet contextual cuing relies not only on spatial attention but also on context processing. Here we isolated habitual attention from context processing in young and older adults. Using a challenging visual search task in which the probability of finding targets was greater in 1 of 4 visual quadrants in all contexts, we examined the acquisition, persistence, and spatial-reference frame of habitual attention. Although older adults showed slower visual search times and steeper search slopes (more time per additional item in the search display), like young adults they rapidly acquired a strong, persistent search habit toward the high-probability quadrant. In addition, habitual attention was strongly viewer-centered in both young and older adults. The demonstration of preserved viewer-centered habitual attention in older adults suggests that it may be used to counter declines in controlled attention. This, in turn, suggests the importance, for older adults, of maintaining habit-related spatial arrangements. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

  4. Identification and assessment of the slowly growing child. (United States)

    Duck, S C


    Reliable measurements taken by trained personnel using appropriate equipment are essential in assessment of the slowly growing child. Linear growth plotted on appropriate statistical charts and expected growth based on parental heights are indicators of inappropriately reduced linear growth. Children older than three years of age who grow less than 1.75 in (4.5 cm) per year should be evaluated. Family and personal medical history (including prenatal and birth information) are important in the identification of familial short stature, constitutional delay and other causes of proportionate growth disorders. Other conditions, including chromosomal disorder, systemic disease and endocrine dysfunction, may be discovered during physical examination or appropriate laboratory investigation. Disproportionate growth of the limbs and trunk suggests the presence of a bone or collagen disorder. Bone age data based on radiographs of the left hand may assist in predicting the child's final height.

  6. MNA® Mini Nutritional Assessment as a nutritional screening tool for hospitalized older adults; rationales and feasibility. (United States)

    Calvo, I; Olivar, J; Martínez, E; Rico, A; Díaz, J; Gimena, M


    The high prevalence of malnutrition in the growing population of older adults makes malnutrition screening critical, especially in hospitalized elderly patients. The aim of our study was to evaluate the use of the MNA® Mini Nutritional Assessment in hospitalized older adults for rapid evaluation of nutritional risk. A prospective cohort study was made of 106 patients 65 years old or older admitted to an internal medicine ward of a tertiary-care teaching hospital to evaluate the use of the short form, or screening phase, of the MNA-SF. In the first 48 hours of admission, the full MNA questionnaire was administered and laboratory tests and a dermatologic evaluation were made. The MNA score showed that 77% of the patients were at risk of malnutrition or were frankly malnourished. Low blood levels of albumin, cholesterol and vitamins A and D showed a statistically significant association with malnutrition or risk of malnutrition. Separate evaluation of the MNA-SF showed that it was accurate, sensitive and had predictive value for the screening process. Routine use of the MNA-SF questionnaire by admission nurses to screen patients is recommended. Patients with MNA-SF scores of 11 or lower should be specifically assessed by the nutritional intervention team.

    Jabbar, Karim; Bjørn, Pernille


    In this paper, we present ethnographic data that unpacks the everyday work of some of the many infrastructuring agents who contribute to creating, sustaining and growing the Blockchain information infrastructure. We argue that this infrastructuring work takes the form of entrepreneurial actions......, which are self-initiated and primarily directed at sustaining or increasing the initiator’s stake in the emerging information infrastructure. These entrepreneurial actions wrestle against the affordances of the installed base of the Blockchain infrastructure, and take the shape of engaging...... or circumventing activities. These activities purposefully aim at either influencing or working around the enablers and constraints afforded by the Blockchain information infrastructure, as its installed base is gaining inertia. This study contributes to our understanding of the purpose of infrastructuring, seen...

  8. Growing Vertical in the Flatland. (United States)

    Robinson, Joshua A


    The world of two-dimensional (2D) heterostructures continues to expand at a rate much greater than anyone could have predicted 10 years ago, but if we are to make the leap from science to technology, many materials challenges must still be overcome. Recent advances, such as those by Liu et al. in this issue of ACS Nano, demonstrate that it is possible to grow rotationally commensurate 2D heterostructures, which could pave the way toward single crystal van der Waals solids. In this Perspective, I provide some insight into a few of the challenges associated with growth of heterostructures, and discuss some of the recent works that help us better understand synthetic realization of 2D heterostructures.

    Sindbæk, Søren Michael


    Long-distance communication has emerged as a particular focus for archaeological exploration using network theory, analysis, and modelling. Initial attempts to adapt methods from social network analysis to archaeological data have, however, struggled to produce decisive results. This paper...... demonstrates how formal network analysis can be combined with a contextual reading of evidence relating to a long-distance communication network in the past. A study of the combined distributions of ten vessel types in 152 settlement sites from the 10th century suggests the outline of the core structure...... of the network. The model implies that 10th century long-distance exchange in the North Sea region featured long-distance links equal to those of the Carolingian emporia trade, and represented a growth in terms of new axes of integration, above all the growing links between the Scandinavian Peninsula...

  10. Growing bubbles rising in line

    Directory of Open Access Journals (Sweden)

    John F. Harper


    Full Text Available Over many years the author and others have given theories for bubbles rising in line in a liquid. Theory has usually suggested that the bubbles will tend towards a stable distance apart, but experiments have often showed them pairing off and sometimes coalescing. However, existing theory seems not to deal adequately with the case of bubbles growing as they rise, which they do if the liquid is boiling, or is a supersaturated solution of a gas, or simply because the pressure decreases with height. That omission is now addressed, for spherical bubbles rising at high Reynolds numbers. As the flow is then nearly irrotational, Lagrange's equations can be used with Rayleigh's dissipation function. The theory also works for bubbles shrinking as they rise because they dissolve.

  11. Morphogenesis of Growing Soft Tissues (United States)

    Dervaux, Julien; Ben Amar, Martine


    Recently, much attention has been given to a noteworthy property of some soft tissues: their ability to grow. Many attempts have been made to model this behavior in biology, chemistry, and physics. Using the theory of finite elasticity, Rodriguez has postulated a multiplicative decomposition of the geometric deformation gradient into a growth-induced part and an elastic one needed to ensure compatibility of the body. In order to fully explore the consequences of this hypothesis, the equations describing thin elastic objects under finite growth are derived. Under appropriate scaling assumptions for the growth rates, the proposed model is of the Föppl von Kármán type. As an illustration, the circumferential growth of a free hyperelastic disk is studied.

  12. Narrative review: hyperkyphosis in older persons. (United States)

    Kado, Deborah M; Prenovost, Katherine; Crandall, Carolyn


    Hyperkyphosis is a widely recognized yet largely ignored condition. Although there are no uniform diagnostic criteria for hyperkyphosis, current studies estimate its prevalence among older adults at 20% to 40%. The causes and consequences of hyperkyphosis are not well understood. Some physicians think that fractures cause hyperkyphosis and that management strategies should focus solely on diagnosis and treatment for osteoporosis. Recent studies, however, demonstrate that many older adults who are most affected by hyperkyphosis do not have vertebral fractures. Hyperkyphosis may be independently associated with an increased risk for adverse health outcomes, including impaired pulmonary function, decreased physical function capabilities, and future fractures. With the growing older population, we now need research that leads to a deeper understanding of the causes, consequences, and treatment of this common condition.

    Tideman, J W L; Polling, J R; van der Schans, A; Verhoeven, V J M; Klaver, C C W


    - Myopia is the eye disorder with the most rapid increase in prevalence worldwide. It develops in childhood, with a peak incidence between the ages of 13 to 15 years. - Especially high myopia, i.e. a refractive error of -6 diopters or more, increases the risk of permanent visual impairment during adulthood due to structural abnormalities of the retina and optic nerve.- The cause of myopia is complex. Lifestyle factors in childhood, such as limited time spent outdoors and close work - such as reading and smartphone usage - are risk factors. Furthermore, genetic studies have revealed more than 100 factors associated with the development of myopia. - Pharmacological and optical interventions to inhibit myopia progression are increasingly applied. The use of atropine eye drops in children and has shown to be an effective treatment.

  15. [Characteristics of heat illness in older people]. (United States)

    Iwata, Mitsunaga; Umegaki, Hiroyuki; Kuzuya, Masafumi; Kitagawa, Yoshimi


    As summer become hotter due to rapid climate change, older people suffering from heat illness are increasing. The aim of our study was to examine the characteristics of older people who suffered from heat illness. We analyzed the 65 years or older patients admitted for acute care of Nagoya Ekisaikai Hospital via the emergency department (ED) during the summer seasons of 2006 and 2007. Demographic data, functional status, use situation of care services, climate of the onset day, use of an air conditioners, and cognitive status, length of hospital stay and disposition following their discharge were recorded. During the study period, 104 patients visited the ED because of heat illness. Twenty older patients were admitted for acute care. In hospitalized patients, the mean length of stay was 27.5+/-18.6 days. Sixty percent of patients were discharged to long-term care facilities (12/20). Sixteen patients suffered from heat illness inside their home. Most of the patients had characteristics such as living alone or with their spouses only (14/16), cognitive dysfunction (12/16), lack or no use of an air conditioner (11/16) , no use of care service (11/16) , and preserved functional status (10/16) . Many older patients suffered from heat illness in their home, and their ED visits were associated with prolonged admissions and post-discharge institutionalizations. It is important to give education to prevent heat illness in older people.

  16. Infection Dynamics on Growing Networks (United States)

    Lai, Ying-Cheng; Liu, Zonghua; Ye, Nong

    We consider the entire spectrum of architectures for large, growing, and complex networks, ranging from being heterogeneous (scale-free) to homogeneous (random or small-world), and investigate the infection dynamics by using a realistic three-state epidemiological model. In this framework, a node can be in one of the three states: susceptible (S), infected (I), or refractory (R), and the populations in the three groups are approximately described by a set of nonlinear differential equations. Our heuristic analysis predicts that, (1) regardless of the network architecture, there exists a substantial fraction of nodes that can never be infected, and (2) heterogeneous networks are relatively more robust against spread of infection as compared with homogeneous networks. These are confirmed numerically. We have also considered the problem of deliberate immunization for preventing wide spread of infection, with the result that targeted immunization can be quite effective for heterogeneous networks. We believe these results are important for a host of problems in many areas of natural science and engineering, and in social sciences as well.

  17. Growing plants on atoll soils

    Energy Technology Data Exchange (ETDEWEB)

    Stone, E L; Migvar, L; Robison, W L


    Many years ago people living on atolls depended entirely on foods gathered from the sea and reefs and grown on land. Only a few plants, such as coconut (ni), Pandanus (bob), and arrowroot (mok-mok), could be grown on the lower rainfall atolls, although adequate groundwater conditions also allowed taro (iaraj, kotak, wot) to be cultivated. On higher rainfall atolls, breadfruit (ma) was a major food source, and banana (binana, kepran), lime (laim), and taros (iaraj, kotak, wot) could be grown. The early atoll populations were experts in growing plants that were vital to sustaining their nutrition requirements and to providing materials for thatch, basketry, cordage, canoe construction, flowers, and medicine. They knew which varieties of food plants grew well or poorly on their atolls, how to propagate them, and where on their atoll they grew best. They knew the uses of most native plants and what the various woods were well suited for. Many varieties of Pandanus (bob) and breadfruit (ma) grew well with high rainfall, but only a few produced well on drier atolls. Such information had been passed down through the generations although some of it has been lost in the last century. Today there are new plants and new varieties of existing plants that can be grown on atolls. There are also new materials and information on how to grow both the old and new plants more effectively. However, there are also introduced weeds and pests to control. Today, there is also an acute need to grow more of the useful plants adapted to atolls. Increasing numbers of people living on an atoll without an equal increase in income or food production stretches the available food supplies. Much has been written about the poor conditions for plant growth on atolls. As compared with many places in the world where crops are grown, however, atolls can provide some highly favorable conditions. For instance, the driving force for plant growth is sunlight, and on atolls light is abundant throughout the

  18. Case grows for climate change

    Energy Technology Data Exchange (ETDEWEB)

    Hileman, B.


    In the four years since the IPCC stated that 'the balance of evidence suggests a discernible human influence on global climate', evidence for anomalous warming has become more compelling, and as a result scientists have become more concerned that human-induced climate change has already arrived. The article summarises recent extra evidence on global temperatures, carbon dioxide measurements, ice shelf breakup, coral bleaching, unstable climates and improved climate models. At the time of the Kyoto conference, the US became keen on the idea that enhancing forest and soil carbon sequestration was a good way to offset emissions reduction targets. Congress is however under the opinion on that the Kyoto protocol presents a threat to the US economy, and senate is very unlikely to ratify the protocol during the Clinton Administration. The debate as to whether the US government should mandate major emission reduction or wait for more scientific certainty may continue for a number of years, but, growing concern of scientists and the public for the harmful effects of climate change may cause a change. 4 figs., 8 photos.

  19. Growing and evolving soft robots. (United States)

    Rieffel, John; Knox, Davis; Smith, Schuyler; Trimmer, Barry


    Completely soft and flexible robots offer to revolutionize fields ranging from search and rescue to endoscopic surgery. One of the outstanding challenges in this burgeoning field is the chicken-and-egg problem of body-brain design: Development of locomotion requires the preexistence of a locomotion-capable body, and development of a location-capable body requires the preexistence of a locomotive gait. This problem is compounded by the high degree of coupling between the material properties of a soft body (such as stiffness or damping coefficients) and the effectiveness of a gait. This article synthesizes four years of research into soft robotics, in particular describing three approaches to the co-discovery of soft robot morphology and control. In the first, muscle placement and firing patterns are coevolved for a fixed body shape with fixed material properties. In the second, the material properties of a simulated soft body coevolve alongside locomotive gaits, with body shape and muscle placement fixed. In the third, a developmental encoding is used to scalably grow elaborate soft body shapes from a small seed structure. Considerations of the simulation time and the challenges of physically implementing soft robots in the real world are discussed.

  20. Pediatric Ovarian Growing Teratoma Syndrome

    Directory of Open Access Journals (Sweden)

    Rebecca M. Rentea


    Full Text Available Ovarian immature teratoma is a germ cell tumor that comprises less than 1% of ovarian cancers and is treated with surgical debulking and chemotherapy depending on stage. Growing teratoma syndrome (GTS is the phenomenon of the growth of mature teratoma elements with normal tumor markers during or following chemotherapy for treatment of a malignant germ cell tumor. These tumors are associated with significant morbidity and mortality due to invasive and compressive growth as well as potential for malignant transformation. Current treatment modality is surgical resection. We discuss a 12-year-old female who presented following resection of a pure ovarian immature teratoma (grade 3, FIGO stage IIIC. Following chemotherapy and resection of a pelvic/liver recurrence demonstrating mature teratoma, she underwent molecular genetics based chemotherapeutic treatment. No standardized management protocol has been established for the treatment of GTS. The effect of chemotherapeutic agents for decreasing the volume of and prevention of expansion is unknown. We review in detail the history, diagnostic algorithm, and previous reported pediatric cases as well as treatment options for pediatric patients with GTS.

    Burke, Megan; Rowe, Theresa


    Vaccines are important for preventing infections in adults aged ≥65 years. Older adults are at increased risk for complications from vaccine-preventable illnesses due to age-associated changes in immune function and chronic medical comorbidities. Vaccination rates for older adults remain low despite widely accepted practice guidelines. Recommended vaccinations for older adults include (1) influenza; (2) pneumococcal; (3) herpes zoster; (4) tetanus, diphtheria, pertussis; and (5) hepatitis B.

  3. Potential Cognitive Benefits From Playing Music Among Cognitively Intact Older Adults: A Scoping Review. (United States)

    Schneider, Catherine E; Hunter, Elizabeth G; Bardach, Shoshana H


    The aging population is growing rapidly, raising rates of cognitive impairment, which makes strategies for protection against cognitive impairment increasingly important. There is little evidence indicating highly effective interventions preventing or slowing onset of cognitive impairment. Music playing influences brain and cognitive function, activating multiple brain areas and using cognitive and motor functions as well as multiple sensory systems, simultaneously. The purpose of this study was to review the current evidence related to playing a musical instrument being a potentially protective mechanism against cognitive decline among older adults. Using scoping review procedures, four databases were searched. Paired reviewers analyzed articles for content, design, and bias. Eleven studies met study criteria and were included in the review. All studies showed that music playing was correlated with positive outcomes on cognitive ability; more high-quality research is needed in this area to understand mechanisms behind potential cognitive protection of music.

  4. Bariatric amputee: A growing problem? (United States)

    Kulkarni, Jai; Hannett, Dominic P; Purcell, Steven


    This study reviewed prevalence of patients with lower limb amputations with above normal weight profile, with body mass index over 25, in seven disablement services centres managing their amputee rehabilitation in the United Kingdom. To review two clinical standards of practice in amputee rehabilitation. Ambulant lower limb amputees should have their body weight recorded on an electronic information system, with identification of cohort with body weight >100 kg. Lower limb amputees to be provided with suitable weight-rated prosthesis. Observational study of clinical practice. Data were collected from the Clinical Information Management Systems. Inclusion criteria--subjects were ambulant prosthetic users with some prosthetic intervention in the last 5 years and had at least one lower limb amputation. In 96% of patients, the weight record profile was maintained. In addition, 86% were under 100 kg, which is the most common weight limit of prosthetic componentry. Of 15,204 amputation levels, there were 1830 transfemoral and transtibial sites in users with body weight over 100 kg. In 60 cases, the prosthetic limb build was rated to be below the user body weight. In 96% of our patients, body weight was documented, and in 97%, the prosthetic limb builds were within stated body weight limits, but this may not be the case in all the other disablement services centres in the United Kingdom. Also, the incidence of obesity in the United Kingdom is a growing problem, and the health issues associated with obesity are further compounded in the amputee population. Prosthetic componentry has distinct weight limits which must be considered during prescription. As people with amputation approach the limits of specific components, clinicians are faced with the challenge of continued provision in a safe and suitable manner. This article reviews the amputee population and the current national profile to consider trends in provision and the incidence of these challenges. © The

  5. Care needs of older patients in the intensive care units. (United States)

    Chang, Ching-Wen; Chen, Yuh-Min; Su, Ching-Ching


    To explore the care needs of older patients in the intensive care units. Background.  As the numbers of older patients admitted to the intensive care units are growing, care quality of critically ill older patients has become an important issue. However, there are few studies directly investigating perceived care needs of hospitalised older patients and the studies on care needs of older patients in the intensive care units are even fewer. The identification of care needs from older patients' perspective will help develop qualified nursing practice. A qualitative exploratory design. Purposive sampling was performed to recruit 35 older patients from three hospitals in Taiwan. The interview transcripts were analysed by qualitative content analysis. The results revealed that care needs of older patients in the intensive care units are multidimensional, including physical, informational and psychosocial dimensions. Older patients' needs of the physical dimension included relieving pain and discomfort, starting oral intake as soon as possible and having continuous sleep. Informational needs included adequate explanations about their disease progression and prognosis and information on recovery-promoting activity. Psychosocial needs included caring behaviour of intensive care units staff, flexible visiting hours, increase in control ability and maintenance of good communication with intensive care units staff. The findings can assist nurses in understanding the interventions necessary to meet care needs of critically ill older patients. The critically ill older adults need more than medical-technical care. They need more holistic care. The psychosocial and informational needs must be considered commensurate with the presenting physical needs. Nurses have an important role in meeting intensive care units older patients' care needs. Intensive care units nurses should conduct comprehensive assessment regarding older patients' needs at the beginning and at various points

    In the context of a rapidly ageing population, Singapore is anticipating a rise in multimorbidity, disability, and dependency, which are driven by physical frailty. Healthy Older People Everyday (HOPE) is an epidemiologic population-based study on community-dwelling older adults aged 65 years and older in Singapore. To investigate the prevalence of frail and prefrail states and their association with polypharmacy, multimorbidity, cognitive and functional status, and perceived health status among community-dwelling older adults in Singapore. Participants for HOPE were older adults aged 65 years and older recruited from a cohort study on the northwest region of Singapore. Analysis was performed on data collected from a combination of interviewer-administered questionnaires (including FRAIL scale, EQ-5D, Mini Mental State Examination, Barthel index, and Lawton IADL scale), clinical assessments, and physical measurements (including hand grip strength and Timed-Up-and-Go [TUG] test). A total of 1051 older adults (mean age 71.2 years) completed the study. More than half (57.2%) were female. The prevalence of frailty and prefrailty was 6.2% and 37%, respectively. Frailty was associated with older age, female gender, Indian (instead of Chinese) ethnicity, multimorbidity, polypharmacy, cognitive and functional impairment, weaker hand grip strength, longer TUG times, and poor perceived health status. Those with underlying cognitive impairment and frailty were at greater risk of adverse health outcome. Frailty is a complex health state with multiple domains and dimensions. In our study in a multiethnic Asian population, we identified nonmodifiable factors and modifiable risk factors (multimorbidity, polypharmacy, cognitive and functional impairment) that were associated with frailty. Interventions will have to be multipronged and will require a collaborated effort in order to effect change and improve the health span in rapidly ageing populations. Copyright © 2017 AMDA

  7. Strategies to improve diet in older adults. (United States)

    Johnson, Mary Ann


    It is estimated that by 2050 there will be 2 billion people aged 60 years and older in the world. The evidence base for the health benefits of good nutrition and physical activity, as well as weight loss among overweight and obese adults, is growing and a number of policies and guidelines are available to guide health professionals in serving older people at various stages of the lifecycle. There are many potential influences on dietary habits including individual factors, families and friends, community characteristics, the food and supplement industry, and public policy. This review focuses on the evidence base for factors influencing diet in older adults, food insecurity, Na, vitamin D, vitamin B12, protein, obesity and the benefits of energy restriction in overweight and obese older adults. Research is needed to continue to increase the evidence base for appropriate ways to improve diet and health in older people. Also, much of the available information is from the US, so there is a need to conduct research in other areas of the world.

  8. The spatialities of ageing: Evidencing increasing spatial polarisation between older and younger adults in England and Wales

    Albert Sabater


    Full Text Available Background: With the proportion of older adults in Europe expected to grow significantly over the next few decades, a number of pertinent questions are raised about the socio-spatial processes that underlie residential age segregation, especially in circumstances where it may be increasing. Objective: We present evidence on whether, and to what degree, residential age segregation has changed across neighbourhoods in England and Wales since the 1990s. Methods: We examine the residential patterns of older adults (aged 65 and over compared to those of younger adults (aged 25-40 for neighbourhoods across the country, for neighbourhoods within districts, and for neighbourhoods within districts classified by type. The analyses use harmonised population data for small areas (Output Areas from the 1991, 2001, and 2011 Censuses of England and Wales. Results: The results reveal increasing segregation over time (1991-2011 between older and younger groups across neighbourhoods nationally. Although the index values of segregation tend to be higher in less urban areas, highlighting a strong age and life course dimension of the rural-urban divide, a rapid increase in age segregation is found in urban areas. Moreover, our findings suggest the existence of convergent clusters of increasing age segregation, particularly in urban settings (from small to large cities and former industrial areas in the North of England, thus providing evidence suggesting a further dimension of the North-South divide. Conclusions: The findings demonstrate a growing age bifurcation over time and space, as both older and younger age groups are increasingly living apart. Although the drivers and consequences of these trends in residential age segregation remain unclear, the potential challenge to policies of social cohesion underlines the importance of further research. Contribution: The findings contribute to current debates about relations between age groups and generations in

  9. Older Motorcyclists in Ireland

    Fitzpatrick, D


    Older motorcyclists are under-recognised as vulnerable road users. Using Irish data from the Central Statistics Office, the Road Safety Authority and the Healthcare Pricing Office, we explored the trend of ageing riders and factors in older motorcyclist collisions and injuries. In 2005, 17 motorcyclists ≥55 were injured compared to 31 in 2012. Motorcyclists aged between 30 and 49 years and ≥50 have longer lengths of stay compared to riders <30. The percentage of motorcycles with an engine capacity of ≥750cc increased from 39.6% in 2007 to 46.7% in 2015. Older motorcyclists are less likely to be fatally injured in single vehicle collisions. Older motorcyclists are generally safer than younger riders but the proportion of older motorcyclist injury is rising. Irish road safety strategies and trauma services need to incorporate these findings into planning and development of preventive and treatment approaches

  10. Aging, disability, and disabled older people in India. (United States)

    Prakash, Indira Jai


    India is witnessing a demographic revolution, leading to a considerable increase in the proportion of older people in the population. Similarly, life expectancy of both the mentally and physically disabled has improved considerably. About 5% of Indian older people have problems with physical mobility. Aging has become a gender issue in India not only because more women are surviving into old age; they are also vulnerable and disadvantaged in many ways. In most cases they are the only caregivers available for the old and disabled. Older Indians are considered a high-risk group for multiple morbidity. It is estimated that nearly four million Indians suffer from mental problems. India has around 12 million people designated as "handicapped." However, little information is available about disabled people who grow older. The National Policy on Older Persons, which has been recently formulated, aims at providing an improved quality of life for millions of older Indians. However, the concerns of older disabled and of the disabled who grow old are still treated separately in both policy and practice.

    Full Text Available Introduction: The aging population is a rapidly growing demographic in the United States. Isolation, limited autonomy, and declining physical and mental health render many older adults vulnerable to elder mistreatment (EM. The purpose of this study was to assess the prevalence and correlates of EM among a sample of older adults using legal assistance services in Atlanta, Georgia.Methods: Researchers administered surveys to consenting older adults (aged 60þ in 5 metro Atlanta community centers that hosted legal assistance information sessions as part of the Elderly Legal Assistance Program. The surveys screened for risk factors and prevalence of EM risk using valid and reliable measures and included additional questions regarding demographics characteristics and healthcare use behaviors.Results: Surveys were completed by 112 participants. Findings reveal that 32 (28.6% respondents met the criteria for elder abuse / neglect risk; 17 (15.2% respondents met criteria for depression; and 105 (93.7% had visited a healthcare provider during the past 6 months.Conclusion: The rates of EM risk in this sample were higher than those previously reported in research. Findings support continued examination of unique risks that may be present among older adults who may be possibly facing legal issues. Additionally, the reported frequency of healthcare visits among participants reveals a promising opportunity to examine development of a more widespread EM screening approach to be conducted in non-emergency settings. Interdisciplinary collaboration is required to inform screening approaches that account for complexities that EM cases present. [West J Emerg Med. 2013;14(4:309–315.

  12. The therapeutic effects of the physician-older patient relationship: Effective communication with vulnerable older patients

    Directory of Open Access Journals (Sweden)

    Summer L Williams


    Full Text Available Summer L Williams, Kelly B Haskard, M Robin DiMatteoDepartment of Psychology, University of California, Riverside, CA, USA Abstract: There is growing evidence that the outcomes of health care for seniors are dependent not only upon patients’ physical health status and the administration of care for their biomedical needs, but also upon care for patients’ psychosocial needs and attention to their social, economic, cultural, and psychological vulnerabilities. Even when older patients have appropriate access to medical services, they also need effective and empathic communication as an essential part of their treatment. Older patients who are socially isolated, emotionally vulnerable, and economically disadvantaged are particularly in need of the social, emotional, and practical support that sensitive provider-patient communication can provide. In this review paper, we examine the complexities of communication between physicians and their older patients, and consider some of the particular challenges that manifest in providers’ interactions with their older patients, particularly those who are socially isolated, suffering from depression, or of minority status or low income. This review offers guidelines for improved physician-older patient communication in medical practice, and examines interventions to coordinate care for older patients on multiple dimensions of a biopsychosocial model of health care.Keywords: physician-patient communication, adherence, health outcomes, vulnerable populations

    Schultz, Kris Ann P; Petronio, Joseph; Bendel, Anne; Patterson, Richard; Vaughn, David J


    Growing teratoma syndrome is characterized by growth of mature teratoma elements of a mixed germ cell tumor despite resolution of immature/malignant elements with administration of chemotherapy. Surgical resection is the only known cure for growing teratoma syndrome but in the brain, complete resection may be impossible. In these instances, mature teratoma, although histologically benign, may be fatal. In this report, we present the case of a child with a large, rapidly growing, unresectable pineal region growing teratoma. PD0332991 was administered with stabilization of the solid, enhancing components of the mass. Minimal adverse effects were noted. © 2014 Wiley Periodicals, Inc.

  14. Knowledge and perceptions of hospice care of Chinese older adults. (United States)

    Enguidanos, Susan; Yonashiro-Cho, Jeanine; Cote, Sarah


    Despite dramatic increases in hospice enrollment, ethnic disparities persist. With rapidly growing populations of Asian Americans, research is needed to elucidate factors that contribute to hospice underenrollment in subgroups of Asian populations. The purpose of this study was to explore older Chinese Americans' knowledge, understanding, and perceptions of hospice care. Three focus groups were conducted, one each in English, Mandarin, and Cantonese, all recruited from a Chinese social service agency. Focus groups were audiotaped and transcribed and then coded for themes. Thirty-four Chinese Americans participated in the groups, all but one reporting primary language other than English. Themes included lack of knowledge, death timing, burden (financial, emotional, physical toward family or government), peaceful death (relief of suffering), and quality of care (and its influence on perception of best care location). Findings indicate the need for hospice education and outreach to Chinese Americans. Additionally, to address concerns about burden and death in the home, efforts to improve access to hospice facilities are needed. Findings from this study provide direction for healthcare providers to address potential barriers to increasing access to hospice of Chinese Americans. © 2013, Copyright the Authors Journal compilation © 2013, The American Geriatrics Society.

  15. ShopComm: Community-Supported Online Shopping for Older Adults. (United States)

    Gorkovenko, Katerina; Tigwell, Garreth W; Norrie, Christopher S; Waite, Miriam; Herron, Daniel


    The United Kingdom has an ageing population whose members experience significant life transitions as they grow older, for example, losing mobility due to deteriorating health. For these adults, digital technology has the potential to sustain their independence and improve their quality of life. However older adults can be reluctant to use digital solutions. In this paper, we review a local charity providing a grocery shopping service for older adults who are unable to go themselves. We explore how older adults perceive the benefits and drawbacks of both physical and digital shopping. Using these insights, we designed ShopComm to enable and support older adults with mobility impairments to shop online.

  16. Problems of rapid growth. (United States)

    Kim, T D


    South Korea's export-oriented development strategy has achieved a remarkable growth record, but it has also brought 2 different problems: 1) since the country's exports accounted for about 1% of total world export volume, the 1st world has become fearful about Korea's aggressive export drive; and 2) the fact that exports account for over 30% of its total gross national product (GNP) exposes the vulnerability of South Korea's economy itself. South Korea continues to be a poor nation, although it is rated as 1 of the most rapidly growing middle income economies. A World Bank 1978 report shows Korea to be 28th of 58 middle income countries in terms of per capita GNP in 1976. Of 11 newly industrializing countries (NIC), 5 in the European continent are more advanced than the others. A recent emphasis on the basic human needs approach has tended to downgrade the concept of GNP. Korea has only an abundant labor force and is without any natural resources. Consequently, Korea utilized an export-oriented development strategy. Oil requirements are met with imports, and almost all raw materials to be processed into exportable products must be imported. To pay import bills Korea must export and earn foreign exchange. It must be emphasized that foreign trade must always be 2-way traffic. In order to export more to middle income countries like Korea, the countries of the 1st world need to ease their protectionist measures against imports from developing countries.

  18. Diabetes, hypertension and mobility among Brazilian older adults: findings from the Brazilian National Household Sample Survey (1998, 2003 and 2008). (United States)

    Nascimento, Clarissa de Matos; Mambrini, Juliana Vaz de Melo; de Oliveira, Cesar Messias; Giacomin, Karla Cristina; Peixoto, Sérgio Viana


    The rapid population ageing has been accompanied by a growing number of older adults experiencing chronic conditions, especially diabetes and hypertension, which are conditions associated to the decline in physical functioning. The aim of this study was to investigate changes in the strength of the association between mobility and two chronic conditions (hypertension and diabetes) in a large representative sample of Brazilian older adults over a ten year period. The data came from the Brazilian National Household Sample Survey (PNAD) of 1998, 2003 and 2008. The sample comprised 28,943 participants aged 60 years and older investigated in 1998, 35,042 in 2003 and 41,269 in 2008, totalling 105,254 older adults. The dependent variable was the physical mobility index (PMI) constructed based on the Item Response Theory (IRT) using five physical mobility indicators. The chronic conditions were self-reported and the confounders included: age, sex, schooling, ethnicity, family income, household composition, other co-morbidities and use of health services. The association between physical mobility (three different groups) and chronic conditions (hypertension and diabetes) was performed using multinomial logistic regression. Over the ten year period the prevalence of hypertension increased from 44 % (1998), 49 % (2003) to 53 % (2008) (p hypertension and diabetes over the ten year period, the decrease in strength of the association with physical mobility during the first period could be explained by improvements in health services and treatment of older adults. Special attention should be given to the treatment and management of diabetes in order to avoid declines in physical mobility levels.

  12. Predictors of diabetes in older people in urban China.

    Directory of Open Access Journals (Sweden)

    Ruoling Chen

    Full Text Available China has the largest number of people with diabetes in the world. Over the last 30 years China has experienced rapid economic growth and a growing income gap between rich and poor. The population is ageing, however diabetes in older people has not been well studied to date. In this study we determined incidence and predictors of diabetes in older Chinese people.During 2001, using a standard interview method, we examined 1,317 adults aged ≥65 years who did not have diabetes in the city of Hefei, and characterized baseline risk factors. Over 7.5 years of follow up, we documented incident diabetes using self-reported doctor diagnosis and the cause of death in the whole cohort, and HbA(1C ≥48 mmol/mol in a nested case-control sample. A multivariate Cox regression model was employed to investigate risk of diabetes in relation to baseline risk factors.During follow up, 119 persons had newly diagnosed diabetes. World age-standardised incidence of diabetes was 24.5 (95% CI 19.5-29.5 per 1,000 person-years. Risk of diabetes was significantly and positively associated with income, waist circumference and body mass index, smoking and uncontrolled hypertension, but negatively associated with having a hobby of walking and frequency of visiting children/other relatives and contacting neighbours/friends. Higher income was significantly associated with increased diabetes risk regardless of cardiovascular and psychosocial risk factors. Compared to those with middle income and no psychosocial risk factors, the hazard ratio for incident diabetes among participants with high income and psychosocial risk was 2.13 (95% CI 1.02-4.45.Increasing incidence of diabetes in relation to high income has become an important public health issue in China. Maintaining social networks and gentle physical activities and reducing psychosocial factors may be integrated into current multi-faceted preventive strategies for curbing the epidemic of diabetes in the older population.

  13. Climate change and older Americans: state of the science. (United States)

    Gamble, Janet L; Hurley, Bradford J; Schultz, Peter A; Jaglom, Wendy S; Krishnan, Nisha; Harris, Melinda


    Older adults make up 13% of the U.S. population, but are projected to account for 20% by 2040. Coinciding with this demographic shift, the rate of climate change is accelerating, bringing rising temperatures; increased risk of floods, droughts, and wildfires; stronger tropical storms and hurricanes; rising sea levels; and other climate-related hazards. Older Americans are expected to be located in places that may be relatively more affected by climate change, including coastal zones and large metropolitan areas. The objective of this review is to assess the vulnerability of older Americans to climate change and to identify opportunities for adaptation. We performed an extensive literature survey and summarized key findings related to demographics; climate stressors relevant to older adults; factors contributing to exposure, sensitivity, and adaptive capacity; and adaptation strategies. A range of physiological and socioeconomic factors make older adults especially sensitive to and/or at risk for exposure to heat waves and other extreme weather events (e.g., hurricanes, floods, droughts), poor air quality, and infectious diseases. Climate change may increase the frequency or severity of these events. Older Americans are likely to be especially vulnerable to stressors associated with climate change. Although a growing body of evidence reports the adverse effects of heat on the health of older adults, research gaps remain for other climate-related risks. We need additional study of the vulnerability of older adults and the interplay of vulnerability, resilience, and adaptive responses to projected climate stressors.

  16. Nursing Students' Willingness to Care for Older Adults in Taiwan. (United States)

    Chi, Mei-Ju; Shyu, Meei-Ling; Wang, Shou-Yu; Chuang, Hsiu-Ching; Chuang, Yeu-Hui


    The possibilities that nurses will take care of persons 65 years of age or older in hospitals and communities are increasing due to a growing aged population. Nursing students should be prepared to face the challenges of their future practice. Therefore, factors associated with nursing students' willingness to care for older adults need to be identified. This study aimed to explore Taiwanese nursing students' willingness to work with older persons and factors associated with this. A cross-sectional research design was used. Stratified sampling was applied to recruit participants from seven nursing schools in northern, central, southern, and eastern areas of Taiwan. There were 612 nursing students who successful completed the questionnaire including demographic data, the Attitudes Toward the Elderly Scale, and the Willingness Toward the Elderly Care Scale. Data were collected between November 2012 and January 2013. A stepwise regression analysis was conducted to identify predictors of nursing students' willingness to care for older adults. The mean score of nursing students' attitudes toward older people was 73.86 (SD = 8.9), with a range of 44-106. The mean score on the willingness to care for older adults was 55.01 (SD = 6.4), with a range of 36-75. The length of time with older adults per week (r = 0.12, p = .003) and grandparents having served as caregivers during the students' childhood (t = -2.147, β = .032) were both positively associated with the willingness to care for older adults. The best predictors of nursing students' willingness to care for older adults were students' attitudes toward older adults (β = 0.38, p nursing students had neutral to slightly favorable attitudes toward working with older adults. Nursing students' positive attitudes about older adults, paying attention to issues related to older adults, and having been a volunteer that served older people were predictors of their willingness to care for older persons.

    Metkar, Umesh; Kurra, Swamy; Quinzi, David; Albanese, Stephen; Lavelle, William F


    Early onset scoliosis can be both a disfiguring as well as a life threatening condition. When more conservative treatments fail, pediatric spinal surgeons are forced to consider operative interventions. Traditionally, these interventions have involved the insertion of a variety of implants into the patient with a limited number of anchor points controlling the spine. In the past, these pediatric patients have had multiple surgeries for elective lengthening of these devices to facilitate their growth while attempting to control the scoliosis. These patients often experience a physical and emotional toll from their multiple repeated surgeries. Growing spine techniques have also had a noted high complication rate due to implant dislodgement and infections. Recently, the development of non-invasively, self-lengthening growing rods has occurred. These devices have the potential to allow for the devices to be lengthened magnetically in a conscious patient in the surgeon's office. Areas covered: This review summarized previously published articles in the English literature using a key word search in PubMed for: 'magnetically controlled growing rods', 'Magec rods', 'magnetic growing rods' and 'growing rods'. Expert commentary: Magnetically controlled growing rods have an advantage over growing rods in lengthening the growing spine in the absence of repetitive surgeries.

  19. Flexible work schedules, older workers, and retirement. (United States)

    Siegenthaler, J K; Brenner, A M


    Older workers in the United States indicate that they would prefer flexible work arrangements rather than abrupt retirement, yet management has done very little to make this possible. A review of two bodies of literature from the late 1980s is presented: social science writings including sociological, gerontological, and economic literature, and business and management literature. There is a clash between the way jobs are traditionally scheduled and the needs of growing numbers of older workers. Workers continue to be subject to obstacles to phased retirement due to the structuring of health care and pension benefits, downsizing, organizational inflexibility, and "corporate culture." Thus, general views among social scientists regarding the desirability of flexible schedules toward retirement will not produce real changes unless management becomes committed to such changes and they are securely embedded in company policies.

  20. Joint Attention is Slowed in Older Adults. (United States)

    Deroche, Thomas; Castanier, Carole; Perrot, Alexandra; Hartley, Alan


    The automatic propensity to orient to the location where other people are looking is the main way of establishing joint attention with others. Whereas joint attention has been mostly investigated with young adults, the present study examines age-related differences in the magnitude and time course of joint attention. Forty-three community-dwelling seniors and 43 younger adults performed a visuospatial task. The procedures closely follow those of gaze-cueing tasks commonly used to investigate joint attention. The findings revealed that a gaze-cueing effect occurs for both younger and older adults, with an equivalent average magnitude but with different time courses. The effect peaks later in older adults. Age-related differences in joint attention could be linked to a more general cognitive slowing rather than to poorer basic social skills. The present study adds to the growing interest in gerontological research regarding social attention.

  1. Growing wealth and growing pains: child and adolescent psychiatry in Hong Kong, Malaysia and Singapore. (United States)

    Tan, Susan; Fung, Daniel; Hung, Se-Fong; Rey, Joseph


    Several Asian regions have undergone a dramatic transformation, some becoming very affluent. This paper aims to ascertain how countries that are becoming wealthy have dealt with child and adolescent mental health issues. Population health status, child and adolescent mental health services, child psychiatry training, the number of child psychiatrists and related matters were examined in Hong Kong, Malaysia and Singapore. Hong Kong, Malaysia and Singapore are ethnically, religiously, socially and politically very different. In spite of considerable wealth and a growing recognition that mental health problems in the young are increasing, they face similar problems--lack of access to treatment due to a dearth of services and a lack of child psychiatrists (2.5, 0.5 and 2.8 per million people, respectively). Because the number of child psychiatrists is so small, their ability to provide services, advocate, train, maintain a professional identity, and deal with future crises is very limited. Other rapidly developing countries can learn from this experience and should take action early to prevent a similar outcome.

  2. Acceptance and Attitudes Toward a Human-like Socially Assistive Robot by Older Adults. (United States)

    Louie, Wing-Yue Geoffrey; McColl, Derek; Nejat, Goldie


    Recent studies have shown that cognitive and social interventions are crucial to the overall health of older adults including their psychological, cognitive, and physical well-being. However, due to the rapidly growing elderly population of the world, the resources and people to provide these interventions is lacking. Our work focuses on the use of social robotic technologies to provide person-centered cognitive interventions. In this article, we investigate the acceptance and attitudes of older adults toward the human-like expressive socially assistive robot Brian 2.1 in order to determine if the robot's human-like assistive and social characteristics would promote the use of the robot as a cognitive and social interaction tool to aid with activities of daily living. The results of a robot acceptance questionnaire administered during a robot demonstration session with a group of 46 elderly adults showed that the majority of the individuals had positive attitudes toward the socially assistive robot and its intended applications.

    We live in a society that idealizes youth. Every day we are exposed to advertisements, social media and TV programs casting the young and beautiful. In our careers, social arenas, and health systems we are encouraged to be fit, healthy, strong, slim, beautiful, efficient, exciting, quick, etc....... These are all qualities that are more pronounced in youth and decrease in old age. At the same time, fewer children are being born in the Western world and people live longer. This leads to a growing proportion of older people in society, who lived long lives and who are likely to have experienced many losses...

  4. Elder Orphans Hiding in Plain Sight: A Growing Vulnerable Population

    Directory of Open Access Journals (Sweden)

    Maria T. Carney


    Full Text Available Adults are increasingly aging alone with multiple chronic diseases and are geographically distant from family or friends. It is challenging for clinicians to identify these individuals, often struggling with managing the growing difficulties and the complexities involved in delivering care to this population. Clinicians often may not recognize or know how to address the needs that these patients have in managing their own health. While many such patients function well at baseline, the slightest insult can initiate a cascade of avoidable negative events. We have resurrected the term elder orphan to describe individuals living alone with little to no support system. Using public data sets, including the US Census and University of Michigan’s Health and Retirement Study, we estimated the prevalence of adults 65 years and older to be around 22%. Thus, in this paper, we strive to describe and quantify this growing vulnerable population and offer practical approaches to identify and develop care plans that are consistent with each person’s goals of care. The complex medical and psychosocial issues for elder orphans significantly impact the individual person, communities, and health-care expenditures. We hope to encourage professionals across disciplines to work cooperatively to screen elders and implement policies to prevent elder orphans from hiding in plain sight.

  5. Methadone Maintenance Treatment for Older Adults: Cost and Logistical Considerations. (United States)

    Cotton, Brandi P; Bryson, William Culbertson; Bruce, Martha L


    In a demographic shift, older adults now comprise an increasing proportion of those receiving methadone maintenance treatment (MMT) for opioid use disorder. A study of MMT recipients in New York City suggests that 13% of the population is over 60 years of age. Adults ages 50-59 are among the largest age demographic, evidence that the number of older adults receiving MMT will continue to increase. Because medical comorbidities, cognitive impairment, and neurobehavioral changes often accumulate with age, older adults on MMT become increasingly vulnerable. The cost of MMT and logistical considerations also pose challenges to continued care. Together, these issues warrant a reconsideration of emerging concerns and health policies related to use of MMT in this growing and understudied population. Given the changing health care system and the opioid epidemic, the need for evidence-based guidelines and supportive policies that consider the unique treatment needs of older populations is especially relevant.

  6. Encouraging homework completion among older adults in therapy. (United States)

    Coon, David W; Gallagher-Thompson, Dolores


    A growing body of research suggests that homework assignments facilitate positive outcomes in psychotherapy. We describe a cognitive behavioral outpatient therapy that stresses the important role homework plays in psychotherapy outcomes and that is found to be successful for treating emotional distress in both older adults and family caregivers. Just as a number of barriers can make it difficult for older clients to commit to regular therapy appointments, a variety of factors can also influence their completion of homework. We also address key issues frequently encountered when fostering homework compliance among older adults and utilize case vignettes to illustrate successful approaches to address these barriers. We present basic tenets for effective homework completion regardless of age group as well as several methods to address homework challenges that we find to be particularly pertinent for therapists treating today's older adults.

  7. The new caring: financial asset management and older people. (United States)

    Tilse, Cheryl; Wilson, Jill; Setterlund, Deborah; Rosenman, Linda


    Increasing longevity and the growing proportion of the aged in the population in most countries have served to focus on the question of how governments and older people can finance living, health, and care options in retirement. Prudent management of income and assets is an increasingly complex and important aspect of aging as assets and expectations of self-financing increase. Although many informal caregivers act as asset managers and/or substitute decision-makers for older people, little attention has been paid to this increasingly important aspect of care. This paper summaries key findings of a broad research program exploring family involvement in the management of older people's assets and the practices that constitute good practice as well as financial mismanagement and abuse. It identifies multi-level and multi-strategy responses needed to address the issues raised by the research and outlines an innovative community demonstration project aimed at improving financial management practices in relation to older people's assets.

  10. Exercise and Older Adults. (United States)

    Mora, Jorge Camilo; Valencia, Willy M


    Regular exercise is essential for healthy aging and offers many health benefits, including reduced risk of all-cause mortality, chronic disease, and premature death. Because physical inactivity is prevalent, greater focus is needed on integrating exercise into care plans and counseling, and developing partnerships that support exercise opportunities. Older adults should be as physically active as their abilities and conditions allow. For substantial health benefits, older adults need to do aerobic, muscle-strengthening, and stretching exercises weekly, and balance activities as needed. Appropriate planning must take account of factors such as prescribed medications, nutrition, injuries, hip and knee arthroplasties, and chronic conditions. Copyright © 2017 Elsevier Inc.

  11. SOFIE, a bicycle that supports older cyclists? (United States)

    Dubbeldam, R; Baten, C; Buurke, J H; Rietman, J S


    Older cyclists remain at high risk of sustaining an injury after a fall with their bicycle. A growing awareness for the need and possibilities to support safety of older cyclists has been leading to bicycle design ideas. However, the effectiveness and acceptance of such designs has not been studied yet. This study aims to analyse the effect of 3 support systems: an automatic adjustable saddle height, optimised frame and wheel geometry and drive-off assistance. The support systems are integrated on the SOFIE bicycle, a prototype bicycle designed to support older cyclists during (dis-)mounting and at lower cycling speeds. Nine older cyclists (65-80 years) were asked to cycle on a 'normal' and on the 'SOFIE' bicycle. They cycled on a parking lot to avoid interaction with traffic. The following tasks were analysed: cycling at comfortable and low speed avoiding an obstacle and (dis-)mounting the bicycle. Bicycle and cyclist motions were recorded with 10 Inertial Measurement Units and by 2 video cameras. FUSION software (LABVIEW) was used to assess kinematic parameters. First, a subjective analysis of the different cycling tasks was made, supported by video analysis. Second, differences in cyclist and bicycle kinematic parameters between the normal and SOFIE bicycle were studied for the various cycling tasks. The SOFIE bicycle was experienced as a 'supportive' and comfortable bicycle and objectively performed 'safer' on various cycling tasks. For example: The optimised frame geometry with low step-in enabled a faster (dis-)mounting time and less sternum roll angle and angular acceleration. The adjustable saddle height enabled the participants to keep both feet on the ground till they started cycling with the 'drive-off' support. The latter reduces steering activity: maximum steer angle and angular acceleration. During sudden obstacle avoidance, less upper body and thigh accelerations are recorded. In conclusion, the SOFIE bicycle was able to support older cyclists during

    Full Text Available This article discusses the importance of a company’s legal form for the process of internationalisation using a sample of 1577 Slovenian companies. We refer to previous studies and on the basis of additional statistical data evaluate whether the choice of corporate legal structure influences a company’s ability to compete internationally. In the domestic market, most companies operate as limited liability companies; this is also the most frequent legal form in which companies enter foreign markets. We conclude that the form by itself does not influence the decision to go international.

  19. [Case report: Rapidly growing abdominal wall giant desmoid tumour during pregnancy]. (United States)

    Palacios-Zertuche, Jorge Tadeo; Cardona-Huerta, Servando; Juárez-García, María Luisa; Valdés-Flores, Everardo; Muñoz-Maldonado, Gerardo Enrique

    Desmoid tumours are one of the rarest tumours worldwide, with an estimated yearly incidence of 2-4 new cases per million people. They are soft tissue monoclonal neoplasms that originate from mesenchymal stem cells. It seems that the hormonal and immunological changes occurring during pregnancy may play a role in the severity and course of the disease. The case is presented on 28-year-old female in her fifth week of gestation, in whom an abdominal wall tumour was found attached to left adnexa and uterus while performing a prenatal ultrasound. The patient was followed up under clinical and ultrasonographic surveillance. When she presented with abnormal uterine activity at 38.2 weeks of gestation, she was admitted and obstetrics decided to perform a caesarean section. Tumour biopsy was taken during the procedure. Histopathology reported a desmoid fibromatosis. A contrast enhanced abdominal computed tomography scan was performed, showing a tumour of 26×20.5×18cm, with well-defined borders in contact with the uterus, left adnexa, bladder and abdominal wall, with no evidence of infiltration to adjacent structures. A laparotomy, with tumour resection, hysterectomy and left salpingo-oophorectomy, components separation techniques, polypropylene mesh insertion, and drainage was performed. The final histopathology report was desmoid fibromatosis. There is no evidence of recurrence after 6 months follow-up. Desmoid tumours are locally aggressive and surgical resection with clear margins is the basis for the treatment of this disease, using radiotherapy, chemotherapy and hormone therapy as an adjunct in the treatment.

  20. Water resources in a rapidly growing region-Oakland County, Michigan (United States)

    Aichele, Stephen S.


    Oakland County is a suburban county in southeast Michigan. Population and demand for water grew steadily in the county over the 20th century, and these trends are expected to continue in coming decades. Roughly 75 percent of current water demand is met by imported water from the Detroit Water and Sewerage Division (DWSD), but water use from ground-water sources within the county still exceeds 43 million gallons per day. Because much of the population growth is in areas beyond the DWSD system, an additional 20-25 million gallons per day of supply may be necessary to meet future demands. Managing the wastewater produced while also protecting human and ecosystem health also may present challenges.

  3. Emerging Development Pathways of Urban Livestock Production in Rapidly Growing West Africa Cities

    Directory of Open Access Journals (Sweden)

    Regina Roessler


    Full Text Available In this study, we try to capture the degree of specialization or integration, and of intensification or extensification, of (peri- urban livestock production, along with the factors that influence such decisions and their impact on natural resource uses. A total of 181 and 187 structured questionnaires were completed in livestock-keeping households in Ouagadougou (Burkina Faso and Tamale (Ghana. Categorical principal component and two-step cluster analysis were used to identify homogenous groups of livestock-keeping households. Cross tabulation and logistic regression analysis revealed factors that influence livestock husbandry, showing their impacts on resource use by livestock keepers in the two cities. A diversity of livestock species was kept, mostly integrated with crop farming. Yet, some households specialized in either sheep, pig or commercial milk production, and partly intensified their production. The decision to specialize and/or intensify livestock production is site-specific and influenced by the education level of the household head and security of land ownership. Higher inputs in livestock systems do not necessarily lead to higher outputs, and specialization inevitably leads to higher manure wastages. Therefore, links of livestock producers to crop farmers and markets for livestock manure must be strengthened to enable recycling of resources and limit negative externalities of specialized livestock production. Strategies need to be identified to improve livestock productivity by enhancing outputs as input use increases.

  4. Scar sarcoidosis on a finger mimicking a rapidly growing soft tissue tumour: a case report

    Directory of Open Access Journals (Sweden)

    Henrichs Marcel-Philipp


    Full Text Available Abstract Background Scar sarcoidosis is a rare and uncommon but specific cutaneous manifestation of sarcoidosis. In general it arises in pre-existing scars deriving from mechanical traumas. As most surgeons dealing with scars might not be aware of cutaneous sarcoidosis and its different types of appearance the appropriate staging and treatment might be missed or at least delayed. To our knowledge this is the first case in literature of scar sarcoidosis on a finger. Case presentation We present a case of a 33-year-old carpenter who developed scar sarcoidosis on his right index finger 4 years after the tendon of the long digital flexor got accidentally cut by an angle grinder. He was referred due to a swelling of the finger suspected to be a malignant soft tissue tumour. The circumference of the affected finger had almost doubled, adding up to 94 mm. Incision biopsy revealed typical noncaseating granulomas. Further investigation showed a systemic extent of the disease with involvement of the lung. A systemic treatment with oral steroids led to an almost full regression of the swelling with restoration of function and resolution of lung infiltrates. Conclusion In case of a suspicious and/or progressive swelling a definite diagnosis should be achieved by biopsy within a short time to enable a proper treatment. If scar sarcoidosis is proven further investigation is necessary to exclude a systemical involvement. A surgical treatment of the swelling is not indicated.

  6. PET/MR - a rapidly growing technique of imaging in oncology and neurology. (United States)

    Sałyga, Alicja; Guzikowska-Ruszkowska, Izabela; Czepczyński, Rafał; Ruchała, Marek


    The combination of positron emission tomography (PET) and magnetic resonance (MR) has become a subject of interest for researchers in the recent several years. Positron emission tomography in combination with magnetic resonance (PET/MR) is the most recent imaging technique classified in the so called hybrid systems category. This review briefly discusses the development history of PET/MR scanners, the principle of their operation, of tandem systems, as well as fully integrated devices. Further, it summarizes recent reports on the application of PET/MR scans and their possible future role in oncological and non-oncological diagnostics. Recent reports regarding the application of PET/MR scanners show huge potential of simultaneously received images, which exceed the advantages of either of those scans used separately. However, the results so far remain uncertain and require further investigations, especially in terms of clinical studies, not only for scientific purposes.

  9. Peptostreptococcus productus strain that grows rapidly with CO as the energy source. (United States)

    Lorowitz, W H; Bryant, M P


    Anaerobic bacteria were enriched with a sewage digestor sludge inoculum and a mineral medium supplemented with B-vitamins and 0.05% yeast extract and with a 50% CO-30% N2-20% CO2 (2 atm [202 kPa]) gas phase. Microscopic observation revealed an abundance of gram-positive cocci, 1.0 by 1.4 micron, which occurred in pairs or chains. The coccus, strain U-1, was isolated by using roll tubes with CO as the energy source. Based on morphology, sugars fermented, fermentation products from glucose (H2, acetate, lactate, and succinate), and other features, strain U-1 was identified as Peptostreptococcus productus IIb (similar to the type strain). The doubling time with up to 50% CO was 1.5 h; acetate and CO2 were the major products. In addition, no significant change in the doubling time was observed with 90% CO. Some stock strains were also able to use CO, although not as well. Strain U-1 produced acetate during growth with H2-CO2. Other C1 compounds did not support growth. Most probable numbers of CO utilizers morphologically identical with strain U-1 were 7.5 X 10(6) and 1.1 X 10(5) cells per g for anaerobic digestor sludge and human feces, respectively.

    The characterization of five Iranian isolates, four from hospital haemodialysis water and one from the sputum of a patient, led to the detection of a novel mycobacterium species. The strains were characterized by mucoid colonies developing in 3-5 days at temperatures ranging from 25 to 37 °C. The biochemical test pattern was unremarkable while the HPLC profile of mycolic acids resembled that of Mycobacterium fortuitum. The sequences of three major housekeeping genes (16S rRNA, hsp65 and rpoB) were unique and differed from those of any other mycobacterium. Mycobacterium brisbanense, which is the species that shared the highest 16S rRNA gene sequence similarity (99.03 %), was distinct, as shown by the average nucleotide identity and by the genome to genome distance values (91.05 and 43.10 %, respectively). The strains are thus considered to represent a novel species of the genus Mycobacterium, for which the name Mycobacterium aquaticum sp. nov. is proposed. The type strain is RW6T (=DSM 104277T=CIP111198T).

    Postpartum depression (PPD) is a significant public health problem adversely affecting mothers, their newborns, and other members of the family. Although PPD is common and potentially dangerous, only a minority of the cases are identified in primary health care settings during routine care, and the majority of depressed mothers in the community lies unrecognized and therefore untreated. In this study, a total of 1500 mothers were approached randomly, 808 accepted to participate, and 504 were within the inclusion criteria (women who had a birth of a singleton full-term healthy infant, had an uncomplicated pregnancy, and were within their one week to six months postpartum). The participants completed the Edinburgh Postnatal Depression Scale. A total of 168 women had an EPDS score ≥10, yielding a crude prevalence rate of 33%. The prevalence of suicidal ideation was 14 out of 504 (3%), among which 11 (79%) had EPDS score of ≥10. We fitted multiple linear regression models to evaluate the predictors of variables measured on the EPDS scale. This model was statistically significant ppredictors. The findings of this study are anticipated to entail the government and policy makers in the region to pay more attention to the apparently high prevalence of unrevealed PPD in the community. It is crucial to enhance screening mechanisms for early detection, providing interventions to manage symptoms, and at the same time mandating local guidelines to address the PPD pathology as a high priority for the UAE population.

  13. Metal-organic frameworks: a rapidly growing class of versatile nanoporous materials. (United States)

    Meek, Scott T; Greathouse, Jeffery A; Allendorf, Mark D


    Metal-organic frameworks (MOFs) represent a new class of hybrid organic-inorganic supramolecular materials comprised of ordered networks formed from organic electron donor linkers and metal cations. They can exhibit extremely high surface areas, as well as tunable pore size and functionality, and can act as hosts for a variety of guest molecules. Since their discovery, MOFs have enjoyed extensive exploration, with applications ranging from gas storage to drug delivery to sensing. This review covers advances in the MOF field from the past three years, focusing on applications, including gas separation, catalysis, drug delivery, optical and electronic applications, and sensing. We also summarize recent work on methods for MOF synthesis and computational modeling.

  15. Contralateral trigeminal neuralgia in a rapidly growing vestibular schwannoma: A case report. (United States)

    Seo, Youngbeom; Kim, Dong Gyu


    We present a rare case of vestibular schwannoma (VS) with contralateral trigeminal neuralgia. A 59 year-old woman presented with right-sided trigeminal neuralgia and a small VS in the left cerebellopontine angle (CPA) that was found via magnetic resonance imaging. The patient was administered medication; however, her symptoms gradually aggravated, and the size of the tumor increased. Two years after the initial diagnosis, the patient underwent surgical resection. After surgical resection, the patient's facial pain was improved. The trigeminal neuralgia appeared to be related to brainstem displacement caused by the contralateral VS. For VS with contralateral trigeminal neuralgia, surgical resection of the tumor should be considered as a possible treatment strategy. Copyright © 2017 Elsevier Ltd. All rights reserved.

  18. Engaging older adults in the visualization of sensor data facilitated by an open platform for connected devices. (United States)

    Bock, Christian; Demiris, George; Choi, Yong; Le, Thai; Thompson, Hilaire J; Samuel, Arjmand; Huang, Danny


    The use of smart home sensor systems is growing primarily due to the appeal of unobtrusively monitoring older adult health and wellness. However, integrating large-scale sensor systems within residential settings can be challenging when deployment takes place across multiple environments, requiring customization of applications, connection across various devices and effective visualization of complex longitudinal data. The objective of the study was to demonstrate the implementation of a smart home system using an open, extensible platform in a real-world setting and develop an application to visualize data real time. We deployed the open source Lab of Things platform in a house of 11 residents as a demonstration of feasibility over the course of 3 months. The system consisted of Aeon Labs Z-wave Door/Window sensors and an Aeon Labs Multi-sensor that collected data on motion, temperature, luminosity, and humidity. We applied a Rapid Iterative Testing and Evaluation approach towards designing a visualization interface engaging gerontological experts. We then conducted a survey with 19 older adult and caregiver stakeholders to inform further design revisions. Our initial visualization mockups consisted of a bar chart representing activity level over time. Family members felt comfortable using the application. Older adults however, indicated it would be difficult to learn to use the application, and had trouble identifying utility. A key for older adults was ensuring that the data collected could be utilized by their family members, physicians, or caregivers. The approach described in this work is generalizable towards future smart home deployments and can be a valuable guide for researchers to scale a study across multiple homes and connected devices, and to create personalized interfaces for end users.

  19. Gene expression in uterine leiomyoma from tumors likely to be growing (from black women over 35 and tumors likely to be non-growing (from white women over 35.

    Directory of Open Access Journals (Sweden)

    Barbara J Davis

    Full Text Available The study of uterine leiomyomata (fibroids provides a unique opportunity to investigate the physiological and molecular determinants of hormone dependent tumor growth and spontaneous tumor regression. We conducted a longitudinal clinical study of premenopausal women with leiomyoma that showed significantly different growth rates between white and black women depending on their age. Growth rates for leiomyoma were on average much higher from older black women than for older white women, and we now report gene expression pattern differences in tumors from these two groups of study participants. Total RNA from 52 leiomyoma and 8 myometrial samples were analyzed using Affymetrix Gene Chip expression arrays. Gene expression data was first compared between all leiomyoma and normal myometrium and then between leiomyoma from older black women (age 35 or older and from older white women. Genes that were found significant in pairwise comparisons were further analyzed for canonical pathways, networks and biological functions using the Ingenuity Pathway Analysis (IPA software. Whereas our comparison of leiomyoma to myometrium produced a very large list of genes highly similar to numerous previous studies, distinct sets of genes and signaling pathways were identified in comparisons of older black and white women whose tumors were likely to be growing and non-growing, respectively. Key among these were genes associated with regulation of apoptosis. To our knowledge, this is the first study to compare two groups of tumors that are likely to have different growth rates in order to reveal molecular signals likely to be influential in tumor growth.

  6. Familism and Health Care Provision to Hispanic Older Adults. (United States)

    Savage, Brittany; Foli, Karen J; Edwards, Nancy E; Abrahamson, Kathleen


    The Hispanic older adult population's rapid growth calls for an awareness of values that can affect the rendering and receipt of care. Familism, or familismo, a traditional Hispanic value, places importance of family over the self and can potentially affect health care perceptions and practices for Hispanic older adults. The current article discusses familism, which is upheld by some Hispanic older adults, and the potential for underuse of health care services. The traditional feminine role, marianismo, and masculine role, machismo, are considered, as well as implications for how decision making may be made by family members rather than the patient. Clinical implications for the provision of health care to Hispanic older adults are provided, along with the importance of considering acculturation and ethnic heterogeneity. Health care management strategies that reflect recognition and respect of familism, yet emphasize optimization of adherence and self-care, are described. Copyright 2016, SLACK Incorporated.

  7. [Treatment of older patients with dyslipidemia]. (United States)

    González, David Fierro


    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.

    A precursory scenario of cultivating the first plants in a lunar greenhouse was elaborated in frames of a conceptual study to grow plants for a permanently manned lunar base. A prototype plant growth system represents an ornamental plant Tagetes patula L. for growing in a lunar rock anorthosite as a substrate. Microbial community anticipated to be in use to support a growth and development of the plant in a substrate of low bioavailability and provide an acceptable growth and blossoming of T. patula under growth limiting conditions.

  13. Frailty in Older People (United States)


    Summary Frailty is the most problematic expression of population ageing. It is a state of vulnerability to poor resolution of homeostasis following a stress and is a consequence of cumulative decline in multiple physiological systems over a lifespan. This cumulative decline erodes homeostatic reserve until relatively minor stressor events trigger disproportionate changes in health status, typically a fall or delirium. Landmark studies have developed valid models for frailty and these have allowed epidemiological studies that demonstrate the association of frailty with adverse health outcomes. New research is needed to develop more efficient methods to detect and severity grade frailty as part of routine clinical practice, particularly methods with utility for primary care. This would greatly inform the appropriate selection of older people for invasive procedures or medications and would be the basis for a paradigm shift in the care of frail older people towards a more appropriate goal-directed care.

  15. Treating diabetes mellitus in older and oldest old patients. (United States)

    Abbatecola, A M; Paolisso, G; Sinclair, A J


    There is a rapidly growing number of persons reaching extreme age limits. Indeed, the fastest growth is found in those over the age of 80 years or octogenarians. Along with this continuous rise, there is a significant increase in type 2 diabetes in this population. Unfortunately, individuals living past 80 years of age are often accompanied by numerous comorbidities and geriatric conditions, all which render anti-diabetic treatment options challenging. Indeed the principles of managing type 2 diabetes are similar to younger patients. Special considerations in this delicate group are essential due to the increased prevalence of comorbidities and relative inability to tolerate adverse effects of medication and severe hypoglycemia. It is important to recall that octogenarians have shown to have a greater prevalence for cognitive impairment, physical disability, ren al and hepatic dysfunction, and syndromes, such as frailty compared to younger elders. The frailty syndrome is considered one of the most important limitations when treating octogenarians with type 2 diabetes in polypharmacy. Due to the lack of evidence for specific targets of glucose and glycated hemoglobin (A1C) levels in the elderly, available treatment guidelines are based on data extrapolation from younger adults and expert opinion citing reliable evidence. Overall, the most important conclusion emerging from these groups is to accomplish a moderate glycemic control (A1C levels between 7 -8%) in complex elderly patients. However, the risk of hypoglycemia from some treatments may present the greatest significant barrier to optimal glycemic control for the very old. The present review discusses the highlights from the latest guidelines for treating older persons and underlines the need for specific considerations when treating the very old in order to maintain a balance between treating comorbidities and maintaining quality of life.

  17. Growing skull fracture in a red-tailed hawk (Buteo jamaicensis). (United States)

    Rush, E Marie; Shores, Andrew; Meintel, Sarah; Hathcock, John T


    Growing skull fractures have been reported in humans for many years, usually resulting from injury to the soft skull during the rapid growth period of an infant's life. Nestling raptors have thin, fragile skulls, a rapid growth rate, and compete aggressively for food items. Skull trauma may occur, which may lead to the development of a growing skull fracture. Growing skull fractures may be under-diagnosed in raptor rehabilitation facilities that do not have access to advanced technologic equipment. Three-dimensional (3-D) computed tomography was used to diagnose a growing skull fracture in a red-tailed hawk (Buteo jamaicensis). The lesion was surgically repaired and the animal was eventually returned to the wild. This is the first report of a growing skull fracture in an animal. In this case, 3-D computed topographic imaging was utilized to diagnose a growing skull fracture in a red-tailed hawk, surgical repair was performed, and the bird recovered completely and was ultimately released.

    Full Text Available Older drivers are frequently viewed as overly represented in crashes, particularly when crash involvement per distance travelled is considered. This perception has led to a call for tighter licensing conditions for older drivers, a policy which inevitably results in mobility restrictions for at least some drivers. However there is a growing body of research evidence which shows that as a group, older drivers represent no greater road risk than drivers from other age groups once different levels of driving activity are taken into account. This paper has examined aspects of older drivers' fitness to drive based on survey data and off-road and on-road driving performance from a sample of 905 New Zealand older drivers. The results show that policies which target all older drivers and lead to licensing and mobility restrictions cannot be justified from a safety basis.

  14. Importance of generativity for healthy aging in older women. (United States)

    Carlson, M C; Seeman, T; Fried, L P


    This article reviewed increasing evidence that remaining physically, cognitively, or socially active confers health benefits by delaying or preventing the onset of disease and disability in older adults. The desire to be generative, or to make a difference, has long been considered an important developmental objective in later years in order to give meaning to one's life, and may provide the necessary impetus for older women to initiate and maintain health-promoting activities. Because the prevalence of disability is greatest in older women, it is critical to find ways to maximize their opportunities for generative activity to promote healthier life-styles. Unfortunately, those who stand to gain most from the promotion of generative roles face many limiting factors, including low education, financial dependence and poverty, primary care-taking responsibilities, social isolation, and low self-efficacy. These obstacles may be too difficult and pervasive for an individual to overcome by oneself. Rather, these challenges need to be addressed through progressive changes in social programs that acknowledge the contributions that older adults can make in later years. Decreasing the structural lag between current social and demographic realities of older women's roles with increasing age will become ever more critical as a growing proportion of older women and men transition from a job outside the home to retirement.

  15. A positivity effect in older adults' memorability judgments of pictures. (United States)

    Tomaszczyk, Jennifer C; Fernandes, Myra A


    BACKGROUND/STUDY CONTEXT: A growing literature suggests that older adults are biased to preferentially cognitively process positively valenced information. The authors investigated whether this bias extended to preferential selection of information to remember, and also examined whether the arousal invoked by stimuli biased item selection and memory. Thirty older (63-88 years of age) and 30 younger (18-25 years of age) adults viewed emotional (positive, negative) and neutral pictures that varied in arousal (low, high), and were asked to select a subset they deemed memorable (memorability judgments), before recalling pictures. Repeated-measures analyses of variance were conducted to examine aging-related differences in selection and recall of positive, negative, and neutral pictures, and of low- and high-arousal pictures. Older adults selected more positive pictures as memorable, whereas in younger adults selection did not differ by valence. In both age groups, recall of positive pictures was highest. Older adults selected more low- than high-arousal pictures as memorable, although recall was greater for high- than low-arousal pictures in both age groups. Findings are consistent with the view that the aging-related positivity bias is under cognitive control, and suggest an awareness of this in older adults. Future investigations should seek to disentangle the influence of positive valence from other factors (e.g., perceptual, semantic, arousal level) on older adults' memorability judgments.

    Full Text Available The results of research work on carrot seed growing through wintering seedlings carried out at laboratory of seed studies and seed production of Transnistrian Research Institute of Agriculture, on the soil of the first terrace at the rive Dniester were presented in the article. Seed bearing plants of garden carrot ‘Krasavka’ were the object of the study. The seeds were sown to produce the seedlings on 15-16 August. In the first decade of December the plants were covered with white agrotextile with density 23g/m2 that was removed at the beginning of April. The proportion of plant that passed the winter depending on a year of cultivation was 95-100% under argotextile, and 50-80% in open plot. The plants under agrotextile reached 28 cm a high and had 5-7 well-developed leaves, while those on the open plot were at phase of active foliage growing about 10-13 cm. long. Thus, for early mechanized planting in optimal terms the wintering seedlings grown under agrotextile had the best biometrical characteristics. Moreover the outcome of carrot seedlings was 1.2-1.25 million per hectare. Such quantity of seedlings was sufficient to plant 9-10 ha of carrot plants, where the coefficient of multiplication reached 9-10, and only 3 when growing seeds through mother plant as biennial culture. Viability of seed plants grown through seedlings was 100%. Losses of plant with weight 120-150 grams from damage caused by diseases was 23%. The seed yield, when growing seedlings was 639 kg/ha, but growing through plants was 332 kg/ha. The seed outcome suitable for precise mechanized sowing through seedling growing was 77%, where seed germination was 90%, with seed fraction 1.51 and >2.0 mm. It was essentially improved their yielding characteristics. Seed outcome from this fraction obtained through planting method was 32%. The proportion of seeds in fraction 1-1.5 mm was 68%. For mechanized single-seed sowing, the seeds can be used only after mini-coating. The seed

  1. Rapid Assessment of Age-Related Differences in Standing Balance

    Directory of Open Access Journals (Sweden)

    Tobias Kalisch


    Full Text Available As life expectancy continues to rise, in the future there will be an increasing number of older people prone to falling. Accordingly, there is an urgent need for comprehensive testing of older individuals to collect data and to identify possible risk factors for falling. Here we use a low-cost force platform to rapidly assess deficits in balance under various conditions. We tested 21 healthy older adults and 24 young adults during static stance, unidirectional and rotational displacement of their centre of pressure (COP. We found an age-related increase in postural sway during quiet standing and a reduction of maximal COP displacement in unidirectional and rotational displacement tests. Our data show that even low-cost computerized assessment tools allow for the comprehensive testing of balance performance in older subjects.

  2. Depression and cognition in older adults. (United States)

    Thomas, Alan J; O'Brien, John T


    Recognition that depression is associated with neurocognitive impairment and renewed recent interest in milder forms of cognitive impairment in older people (typified by the concept of mild cognitive impairment) have stimulated researchers to investigate the relationship between depression and cognitive impairment. This review identifies and clarifies recent progress in this rapidly developing research area. Neurocognitive impairment persists in most depressed older people after clinical recovery, and slowed information processing speed and possibly executive dysfunction and vascular risk factors underlie this. Most studies suggest that this neurocognitive impairment in turn leads to increased mild cognitive impairment as well as dementia. White matter disease appears to directly contribute to depression in older people and this worsens over time. Polymorphisms in the serotonin transporter gene may be a key risk factor as well, and depression worsens vascular outcome in peripheral arterial disease. Clinicians should be aware that neurocognitive deficits persist and have an adverse effect on outcome, and that vascular risk factors may contribute to these deficits.

  3. Perspective on how laser-ablated particles grow in liquids (United States)

    Zhang, DongShi; Liu, Jun; Liang, ChangHao


    Laser ablation in liquids has emerged as a new branch of nanoscience for developing various nanomaterials with different shapes. However, how to design and control nanomaterial growth is still a challenge due to the unique chemical-physical process chain correlated with nanomaterial nucleation and growth, including plasma phase (generation and rapid quenching), gas (bubble) phase, and liquid phase. In this review, through summarizing the literature about this topic and comparing with the well-established particle growth mechanisms of the conventional wet chemistry technique, our perspective on the possible nanoparticle growth mechanisms or routes is presented, aiming at shedding light on how laser-ablated particles grow in liquids. From the microscopic viewpoint, the nanoparticle growth contains six mechanisms, including LaMer-like growth, coalescence, Ostwald ripening, particle (oriented) attachment, adsorbate-induced growth and reaction-induced growth. For each microscopic growth mechanism, the vivid growth scenes of some representative nanomaterials recorded by TEM and SEM measurements are displayed. Afterwards, the scenes from the macroscopic viewpoint for the large submicro- and micro-scale nanospheres and anisotropic nanostructures formation and evolution from one nanostructure into another one are presented. The panorama of how diverse nanomaterials grow during and after laser ablation in liquids shown in this review is intended to offer a overview for researchers to search for the possible mechanisms correlated to their synthesized nanomaterials, and more expectation is desired to better design and tailor the morphology of the nanocrystals synthesized by LAL technique.

  4. [Communication with surgical patients of older age on the internet]. (United States)

    Brangan, Sanja; Sonicki, Zdenko


    A growing interest of general population to seek health information on the Internet and a growing body of health websites have been well documented in the recent health literature. Moreover, the Internet has become a popular mode of communication between healthcare providers and patients. This has resulted in many efforts to set specific quality guidelines for development of information for patients on the Internet, including different aspects of access to health information. This paper presents results of a study that explored the structure of information sources of surgical patients. Analysis of patient profiles shows that older patients rarely sought surgical information on the Internet, and mostly relied on communication with their doctors. This paper discusses various options of how to make this medium more attractive to patients and how to use the rich experience of the older patient generations to improve the quality of doctor-patient communication.

  5. Struggling for existence-Life situation experiences of older persons with mental disorders. (United States)

    Martinsson, Gunilla; Fagerberg, Ingegerd; Lindholm, Christina; Wiklund-Gustin, Lena


    Older persons with mental disorders represent a vulnerable group of people with extensive and complex needs. The older population is rapidly increasing worldwide and, as a result of deinstitutionalization in mental health care, older persons are remaining at home to a greater extent. Although they constitute a large proportion of the population, older persons with mental disorders have been neglected in research as well as in care organizations. As there is little previous knowledge concerning older persons' experiences of their own situations, this study aimed to illuminate the meaning of the life situation as experienced by older persons with mental disorders (excluding dementia disorders). Interviews were conducted with seven older persons and the text was analyzed using a phenomenological hermeneutical research method, inspired by the philosophy of Paul Ricoeur. "Struggling for existence" emerged as a main theme in the older persons' narratives, understood as a loss of dignity of identity and involving being troubled and powerless as well as yearning for respect. The older persons fought to master their existence and to be seen for who they are. The study highlights the importance for caregivers, both formal and informal, to avoid focusing on the diagnoses and rather acknowledge the older persons and their lifeworld, be present in the relation and help them rebuild their dignity of identity. This study brings a new understanding about older persons with mental disorders that may help reduce stigma and contribute to planning future mental health care.

  8. Beyond WhatsApp: Older people and smartphones

    Directory of Open Access Journals (Sweden)

    Andrea Rosales


    Full Text Available This paper analyzes how older people, living in Spain, use smartphones and smartphone applications. Using a mixed methods approach, we compare quantitative results obtained by tracking mobile app usage amongst different generational samples with qualitative, focus-group discussions with active smartphone users. A sample of Spanish smartphone users were tracked during one month in the winter of 2014 (238 individuals, aged 20 to 76 years-old. This was followed by three focus group sessions conducted in the spring of 2015, with 24 individuals aged 55 to 81. As we learned, WhatsApp is currently the most popular application used by people of all ages, including older adults. Smartphones increasingly are playing a central role in the life of older participants, although the frequency of app access is negatively correlated with age. On the other hand, as our data indicates, older adults also use a number of different types of apps that are distinct from that of younger users. Older participants access personal information manager apps (calendar, address book and notes more often than other age groups. And comparatively, older participants use the smartphone less often in stable locations (home, office, relatives’ home with Wifi than somewhere else and with mobile data. As we argue, differences in age seem to reflect the evolution in personal interests and communication patterns that change as we grow older. Our study captures new trends in smartphone usage amongst this cohort. It also indicates how a combination of methods may help to assess the validity of the log and qualitative data. We highlight the relevance of conducting careful generational studies in smartphone use and some of the potentials and limitations of making predictive studies of ICT use as we change throughout the life course. Finally, we assert the value of the inclusion of older representatives within research, which ultimately may influence public decisions and the design of new

  9. Social marketing strategies for reaching older people with disabilities: findings from a survey of centers for independent living participants. (United States)

    Moone, Rajean Paul; Lightfoot, Elizabeth


    Centers for independent living (CILs) provide critical supports, services, and advocacy for assisting people with disabilities in living independently. As there is a rapidly increasing population of older people with disabilities, many CILs are now considering how to actively engage older adults in their organizations. This study utilized a survey of older people with disabilities to help identify social marketing techniques that community organizations like CILs can use to effectively reach older people with disabilities. Utilizing the components of the social marketing mix in designing outreach efforts, including a critical examination of product, place, price, participants, and partnering, CILs and other community agencies can better reach older adults with disabilities.

  10. Tuberculosis in Older Adults. (United States)

    Rajagopalan, Shobita


    Tuberculosis (TB) remains one of the world's most lethal infectious diseases. Preventive and control strategies among other high-risk groups, such as the elderly population, continues to be a challenge. Clinical features of TB in older adults may be atypical and confused with age-related diseases. Diagnosis and management of TB in the elderly person can be difficult; treatment can be associated with adverse drug reactions. This article reviews the current global epidemiology, pathogenesis, clinical characteristics, diagnosis, management, and prevention of Mycobacterium tuberculosis infection in community-dwelling and institutionalized aging adults.

  12. Learning Topologies with the Growing Neural Forest. (United States)

    Palomo, Esteban José; López-Rubio, Ezequiel


    In this work, a novel self-organizing model called growing neural forest (GNF) is presented. It is based on the growing neural gas (GNG), which learns a general graph with no special provisions for datasets with separated clusters. On the contrary, the proposed GNF learns a set of trees so that each tree represents a connected cluster of data. High dimensional datasets often contain large empty regions among clusters, so this proposal is better suited to them than other self-organizing models because it represents these separated clusters as connected components made of neurons. Experimental results are reported which show the self-organization capabilities of the model. Moreover, its suitability for unsupervised clustering and foreground detection applications is demonstrated. In particular, the GNF is shown to correctly discover the connected component structure of some datasets. Moreover, it outperforms some well-known foreground detectors both in quantitative and qualitative terms.

  13. Coming of Age: Considerations in the Prescription of Exercise for Older Adults. (United States)

    Zaleski, Amanda L; Taylor, Beth A; Panza, Gregory A; Wu, Yin; Pescatello, Linda S; Thompson, Paul D; Fernandez, Antonio B


    Older adults represent the fastest-growing age demographic of the population. Physiological changes associated with primary aging and concurrent chronic disease adversely impact functional capacity, health outcomes, and quality of life. For these reasons, there is a national emphasis for healthcare providers to improve the health, function, and quality of life of older adults to preserve independent living and psychological well-being. The benefits of regular physical activity or exercise with regard to aging and disease are indisputable, yet many clinicians do not prescribe exercise to older adults. This reluctance may be attributable to a lack of knowledge regarding appropriate exercise prescription for older adults in light of the potential risks and benefits of various doses and types of exercise. In addition, clinicians and patients may have concerns about potential health considerations relevant to older adults such as comprehensive pre-exercise screening and exercise-drug interactions. In light of this, the following review presents (1) guidelines for exercise prescription in older adults and modification of these guidelines for patients with the most common age-associated comorbidities; (2) recommendations for pre-exercise screening prior to initiating an exercise program in older adults; (3) considerations for older adults on one or more medications; and (4) common barriers to adopting and maintaining exercise in an older population. Our goal is to provide a framework that clinicians can follow when prescribing exercise in older adults while considering the unique characteristics and concerns present in this population.

  14. Fruit-Growing in Latvia – Industry and Science

    Directory of Open Access Journals (Sweden)

    Kaufmane Edīte


    Full Text Available In all times, fruit trees for family use have been grown at Latvian farms. Yet these fruits obtained market value only after the land ownership reform in 19th century. This facilitated rapid area increase of different fruit crops, allowing supply with fruits not only the local market, but also for export to the largest cities of Russia. Especially fast development of fruit-growing was observed during the first independent republic (1919–1940. The demand for planting material increased, and plants were imported from Western Europe. Choice of unsuitable cultivars and rootstocks was the main reason of the massive orchard area loss during the following severe winters. After the Second World War, the Soviet powers supported only the establishment of large orchards for processing needs, 200-300 ha, which were unsuitable for the Latvian climate and terrain. At the same time, numbers of allotment gardens rapidly increased and part of their produce was sold also on the market. After regaining of independence and private property, interest in fresh fruit and berry production for market, as well as processing, renewed. It was hindered by lack of continuity in experience and knowledge. Diversity of terrain, soils and climate all demand considerate choice of suitable orchard location and cultivars. Direct use of foreign experience often led to failure. At present, development of the fruit industry is most of all hindered by lack of qualified specialists of different levels, which does not allow to establish an appropriate consulting system. Cooperation of growers for easier marketing also is developing too slowly. Insufficient economic and market research does not allow to balance the demand with increase of plantation area, especially for large-scale processing and export, so strategic guidance of the fruit industry is not possible. Development of fruit-growing is hindered also by a lack of continuous long-term support to horticultural science. As a

    Wang, Xin; Stone, Howard A.; Golestanian, Ramin


    The spatial organization of bacteria in dense biofilms is key to their collective behaviour, and understanding it will be important for medical and technological applications. Here we study the morphology of a compact biofilm that undergoes unidirectional growth, and determine the condition for the stability of the growing interface as a function of the nutrient concentration and mechanical tension. Our study suggests that transient behaviour may play an important role in shaping the structure of a biofilm.

  2. Factors that influence older people's engagement with digital health technology. (United States)

    Curtis, Katherine; Price, Kyle


    Digital health technology (DHT) encompasses a wide range of applications and interventions with the potential to address the health needs of an increasingly ageing population. Older people's engagement with DHT depends on many factors, and this article summarises understanding of the barriers and facilitators to DHT uptake and continued use among older people. Older people's confidence in using digital technology, their perceptions of personal benefit from DHT, its design, and the support they receive from health professionals and carers in using DHT all affect their level of engagement. Understanding these barriers and facilitators among the older population creates ways to enable greater numbers to benefit from DHT. This article provides information for those who work with, or design digital health interventions for, older people to help them to influence older people's engagement with these rapidly evolving healthcare innovations. ©2017 RCN Publishing Company Ltd.

  3. Rapid Airplane Parametric Input Design (RAPID) (United States)

    Smith, Robert E.


    RAPID is a methodology and software system to define a class of airplane configurations and directly evaluate surface grids, volume grids, and grid sensitivity on and about the configurations. A distinguishing characteristic which separates RAPID from other airplane surface modellers is that the output grids and grid sensitivity are directly applicable in CFD analysis. A small set of design parameters and grid control parameters govern the process which is incorporated into interactive software for 'real time' visual analysis and into batch software for the application of optimization technology. The computed surface grids and volume grids are suitable for a wide range of Computational Fluid Dynamics (CFD) simulation. The general airplane configuration has wing, fuselage, horizontal tail, and vertical tail components. The double-delta wing and tail components are manifested by solving a fourth order partial differential equation (PDE) subject to Dirichlet and Neumann boundary conditions. The design parameters are incorporated into the boundary conditions and therefore govern the shapes of the surfaces. The PDE solution yields a smooth transition between boundaries. Surface grids suitable for CFD calculation are created by establishing an H-type topology about the configuration and incorporating grid spacing functions in the PDE equation for the lifting components and the fuselage definition equations. User specified grid parameters govern the location and degree of grid concentration. A two-block volume grid about a configuration is calculated using the Control Point Form (CPF) technique. The interactive software, which runs on Silicon Graphics IRIS workstations, allows design parameters to be continuously varied and the resulting surface grid to be observed in real time. The batch software computes both the surface and volume grids and also computes the sensitivity of the output grid with respect to the input design parameters by applying the precompiler tool

  4. Exposure to vibrations in wine growing

    Directory of Open Access Journals (Sweden)

    Domenico Pessina


    Full Text Available Apart the winter period, the activity in specialized agricultural cultivations (i.e. wine- and fruit-growing is distributed for a long period of the year. Some tasks, such as pesticide distribution, are repeated several times during the growing season. On the other hand, mechanization is one of the pillars on which is based the modern agriculture management. As a consequence, in wine growing the tractor driver has to be considered a worker potentially subjected to high level of vibrations, due to the poor machinery conditions often encountered, and sometimes to the rough soil surface of the vineyard combined with the high travelling speed adopted in carrying out many operations. About vibrations, the Italian Decree 81/08 basically refers to the European Directive 2002/44/CE, that provides some very strict limits of exposure, both for whole body and hand-arm districts. In Oltrepo pavese, a large hilly area located the south part of the Pavia province (Lombardy - Italy wine growing is the main agricultural activity; for this reason, a detailed survey on the vibration levels recorded at the tractor driver’s seat was carried out, in order to ascertain the real risk to which the operators are exposed. The activity in wine growing has been classified into 6 groups of similar tasks, as follows: 1. canopy management: pruning, trimming, binding, stripping, etc.; 2. soil management: harrowing, hoeing, subsoiling etc.; 3. inter-row management: chopping of pruning , pinching, grass mowing, etc.; 4. crop protection: pesticides and fungicides distribution, sulfidation, foliar fertilization, etc.; 5. grape harvesting: manual or mechanical; 6. transport: from the vineyard to the cellar. For each group of tasks, the vibration levels on 3 the traditional axes (x, y and z were recorded, and then an exposure time was calculated for each of them, in order to ascertain the risk level in comparison to what provided by the dedicated standard. Finally, a detailed

  12. RAPID3? Aptly named! (United States)

    Berthelot, J-M


    The RAPID3 score is the sum of three 0-10 patient self-report scores: pain, functional impairment on MDHAQ, and patient global estimate. It requires 5 seconds for scoring and can be used in all rheumatologic conditions, although it has mostly been used in rheumatoid arthritis where cutoffs for low disease activity (12/30) have been set. A RAPID3 score of ≤ 3/30 with 1 or 0 swollen joints (RAPID3 ≤ 3 + ≤ SJ1) provides remission criteria comparable to Boolean, SDAI, CDAI, and DAS28 remission criteria, in far less time than a formal joint count. RAPID3 performs as well as the DAS28 in separating active drugs from placebos in clinical trials. RAPID3 also predicts subsequent structural disease progression. RAPID3 can be determined at short intervals at home, allowing the determination of the area under the curve of disease activity between two visits and flare detection. However, RAPID3 should not be seen as a substitute for DAS28 and face to face visits in routine care. Monitoring patient status with only self-report information without a rheumatologist's advice (including joints and physical examination, and consideration of imaging and laboratory tests) may indeed be as undesirable for most patients than joint examination without a patient questionnaire. Conversely, combining the RAPID3 and the DAS28 may consist in faster or more sensitive confirmation that a medication is effective. Similarly, better enquiring of most important concerns of patients (pain, functional status and overall opinion on their disorder) should reinforces patients' confidence in their rheumatologist and treatments.

  13. Feelings of Gratitude Toward God Among Older Whites, Older African Americans, and Older Mexican Americans (United States)

    Krause, Neal


    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

  15. Alcohol and other substance use, mental health treatment use, and perceived unmet treatment need: Comparison between baby boomers and older adults. (United States)

    Choi, Namkee G; DiNitto, Diana M; Marti, C Nathan


    As the baby boomers age, the number of older adults with comorbid substance use and mental disorders is projected to grow. Little research has examined the potential impact of substance use on older adults' mental health treatment use and unmet treatment need. This study examined these associations among the rapidly growing population of baby boomers and their older counterparts. Data are from the 2008 to 2012 National Survey on Drug Use and Health (NSDUH) (N = 18,443 respondents aged 50-64 and 11,191 aged 65 +). Age-combined and age-stratified logistic regression analyses were used to examine relationships between alcohol, illicit drug, and tobacco use and mental health problems, treatment use, and perceived unmet treatment need, with sociodemographic characteristics and health status as covariates. Heavy alcohol, illicit drug, and tobacco use increased the odds of having a mental health problem in both age groups. Compared to those who used alcohol on 1-99 days during the preceding year, lifetime abstainers had significantly lower odds of having received mental health treatment in both age groups. Poorer self-rated health and past-year mental health treatment use increased the odds of perceived unmet treatment need in both age groups, while lifetime abstention in the boomers decreased the odds. This study's key finding is the lower likelihood of mental health treatment use among lifetime abstainers in both age groups. Further research may identify barriers to treatment use and ways to promote use among both age groups. © American Academy of Addiction Psychiatry.

  16. Growing media constituents determine the microbial nitrogen conversions in organic growing media for horticulture. (United States)

    Grunert, Oliver; Reheul, Dirk; Van Labeke, Marie-Christine; Perneel, Maaike; Hernandez-Sanabria, Emma; Vlaeminck, Siegfried E; Boon, Nico


    Vegetables and fruits are an important part of a healthy food diet, however, the eco-sustainability of the production of these can still be significantly improved. European farmers and consumers spend an estimated €15.5 billion per year on inorganic fertilizers and the production of N-fertilizers results in a high carbon footprint. We investigated if fertilizer type and medium constituents determine microbial nitrogen conversions in organic growing media and can be used as a next step towards a more sustainable horticulture. We demonstrated that growing media constituents showed differences in urea hydrolysis, ammonia and nitrite oxidation and in carbon dioxide respiration rate. Interestingly, mixing of the growing media constituents resulted in a stimulation of the function of the microorganisms. The use of organic fertilizer resulted in an increase in amoA gene copy number by factor 100 compared to inorganic fertilizers. Our results support our hypothesis that the activity of the functional microbial community with respect to nitrogen turnover in an organic growing medium can be improved by selecting and mixing the appropriate growing media components with each other. These findings contribute to the understanding of the functional microbial community in growing media and its potential role towards a more responsible horticulture. © 2016 The Authors.

    This paper presents a novel method for parallelizing the seeded region growing (SRG) algorithm using Compute Unified Device Architecture (CUDA) technology, with intention to overcome the theoretical weakness of SRG algorithm of its computation time being directly proportional to the size of a segmented region. The segmentation performance of the proposed CUDA-based SRG is compared with SRG implementations on single-core CPUs, quad-core CPUs, and shader language programming, using synthetic datasets and 20 body CT scans. Based on the experimental results, the CUDA-based SRG outperforms the other three implementations, advocating that it can substantially assist the segmentation during massive CT screening tests.

  20. Mapping Nutrients Crucial to a Growing Population (United States)

    Tarnowski, J. R.; Cassidy, E. S.; Gerber, J. S.


    Over two billion people worldwide suffer from inadequate levels of micronutrients, mainly in the form of iodine, iron, and vitamin A deficiencies. With a growing population, producing crops that contain high amounts of these micronutrients is of increased importance. Addressing these deficiencies sustainably requires a detailed examination of the agricultural production of the micronutrients. The purpose of this study is to determine whether or not enough of these important nutrients are produced to meet the nutritional needs of the global population, and to determine where nutrients are most deficient. We used area specific crop production data to map where and how much iron and vitamin A are produced from major crops.

  1. Growing in darkness: The etiolated lupin hypocotyls


    Sánchez-Bravo, José; Oliveros-Valenzuela, M Rocío; Nicolás, Carlos; Acosta, Manuel


    Epigeal germination of a dicot, like lupin (Lupinus albus L.), produces a seedling with a characteristic hypocotyl, which grows in darkness showing a steep growth gradient with an elongation zone just below the apex. The role of phytohormones, such as auxin and ethylene, in etiolated hypocotyl growth has been the object of our research for some time. The recent cloning and expression of three genes of influx and efflux carriers for polar auxin transport (LaAUX1, LaPIN1 and LaPIN3) reinforces ...

  2. Campylobacter infection has different outcomes in fast- and slow-growing broiler chickens. (United States)

    Williams, L K; Sait, L C; Trantham, E K; Cogan, T A; Humphrey, T J


    Campylobacter spp. are frequently carried by poultry, but they are not believed to cause significant disease in these animals. Modern poultry breeds have been selected to grow rapidly under intensive conditions, but recently, consumers have moved toward purchasing birds produced in higher welfare, free-range or organic systems. Birds reared in these systems tend to be a slower growing breed and are fed a different diet. Birds reared in such systems are stocked at a lower density compared with the standard conventional broilers, and they have access to environmental enrichment, such as perches. In previous research, these slower growing birds have been shown to have different levels of Campylobacter carriage in commercial rearing conditions, but the reasons for, and effect of, these different levels are unknown; is it the bird breed, diet, or environmental conditions? In this study, experimental flocks of fast- and slow-growing breeds of broiler chickens were reared to a standard commercial slaughter weight, with their weight gain being measured during the growing period. At 21 days, birds were either infected with Campylobacter jejuni or given a placebo as control. Cohorts of birds were euthanatized at various intervals, and samples were taken for examination for Campylobacter. The fast-growing birds gained weight more rapidly than the slow-growing birds. By 2 days postinfection (dpi), C. jejuni was detected in the caeca and by enrichment from the liver and spleen samples from both breeds of birds. Low-level colonization persisted in the spleen and liver samples but was undetectable by 28 dpi. Fast- and slow-growing birds did not show detectably different levels of Campylobacter carriage. Infection with C. jejuni affected the incidence of hock marks and pododermatitis in both breeds of birds, but the differences were greater with the fast-growing breed compared with the uninfected control birds. In addition, the incidence of pododermatitis was significantly higher

  3. The Impact of Cuban Economic Reform on Older Persons. (United States)

    Strug, David L


    This paper discusses the economic reforms initiated by Cuban President Raúl Castro in 2008 and its effect on the country's fast-growing, vulnerable population of older persons 60+ years of age. Cubans are living longer and the country has a very low birthrate. These two factors combined have reduced the proportion of the population in the work force. This adversely affects the economy. Population aging is a major reason why the government has introduced structural reforms and reduced social spending, which have weakened the welfare state on which older persons depend. Many older persons have become critical of the reforms over time. Policy makers need to address the impact the reforms are having on older Cubans and consider them as active participants in economic reform. Data for this paper come from qualitative, case study research carried out in Havana between the years 2008-15 and from a review of the literature on aging and economic reforms in Cuba. Two case studies illustrate the impact of the economic reforms on older persons.

  4. Sexuality in older adults

    Directory of Open Access Journals (Sweden)

    Adrián Sapetti


    Full Text Available Just as the body and its functions undergo changes with age, in the same way sexuality shares this aging process. However, remember a golden rule that we are sexual since we are born until we die; only possibilities are modified with the passage of the years. This article intends to show the changes that occur in the sexual response of the elderly. If sexual life during youth was pleasant and satisfactory this will condition sexuality in the socalled third age and the elderly seek to maintain it, this is not the case for those who had a dysfunctional past. This article briefly describes the andropause and the SIM, vicissitudes, changes and differences in sexual response and chances to maintain eroticism in the older adult. 

  5. Advanced technology care innovation for older people in Italy: necessity and opportunity to promote health and wellbeing. (United States)

    Lattanzio, Fabrizia; Abbatecola, Angela M; Bevilacqua, Roberta; Chiatti, Carlos; Corsonello, Andrea; Rossi, Lorena; Bustacchini, Silvia; Bernabei, Roberto


    Even though there is a constant and accelerating growth of the aging population worldwide, such a rapid rise is negatively impacting available home and community services not able to encompass the necessities associated with the increased number of older people. In particular, there are increasing demands on e-health care services and smart technologies needed for frail elders with chronic diseases and also for those experiencing active aging. Advanced Technology Care Innovation for older persons encompasses all sectors (assistive technology, robotics, home automation, and home care- and institution-based healthcare monitoring, telemedicine) dedicated to promoting health and wellbeing in all types of living environments. Considering that there is a large concern and demand by older persons to remain in familiar social living surroundings, study projects joined with industries have been currently initiated, especially across Europe to improve health and wellbeing. This article will highlight the latest updates in Europe and, in particular in Italy, regarding scientific projects dedicated to unraveling how diverse needs can be translated into an up-to-date technology innovation for the growing elder population. We will provide information regarding advanced technology designed for those with specific geriatric-correlated conditions in familiar living settings and for individuals aging actively. This is an important action because numerous emerging developments are based on user needs identified by geriatricians, thus, underlining the indispensable role of geriatric medicine toward future guidelines on specific technology.

  6. Do current national and international guidelines have specific recommendations for older adults with bipolar disorder? A brief report. (United States)

    Dols, Annemiek; Kessing, Lars Vedel; Strejilevich, Sergio A; Rej, Soham; Tsai, Shang-Ying; Gildengers, Ariel G; Almeida, Osvaldo P; Shulman, Kenneth I; Sajatovic, Martha


    Older adults with bipolar disorder (OABD) are a growing segment of patients with bipolar disorder (BD) for which specific guidelines are warranted. Although, OABD are frequently excluded from randomized controlled trials due to their age or somatic comorbidity, more treatment data from a variety of sources have become available in recent years. It is expected that at least some of this emerging information on OABD would be incorporated into treatment guidelines available to clinicians around the world. The International Society of Bipolar Disorders OABD task force compiled and compared recommendations from current national and international guidelines that specifically address geriatric or older individuals with BD (from year 2005 onwards). There were 34 guidelines, representing six continents and 19 countries. The majority of guidelines had no separate section on OABD. General principles for treating OABD with medication are recommended to be similar to those for younger adults, with special caution for side effects due to somatic comorbidity and concomitant medications. Therapeutic lithium serum levels are suggested to be lower but recommendations are very general and mostly not informed by specific research evidence. There is a lack of emphasis of OABD-specific issues in existing guidelines. Given the substantial clinical heterogeneity in BD across the life span, along with the rapidly expanding population of older individuals worldwide, and limited mental health workforce with geriatric expertise, it is critical that additional effort and resources be devoted to studying treatment interventions specific to OABD and that treatment guidelines reflect research findings.

  7. Factors influencing the life satisfaction in the older Korean women living alone. (United States)

    Kim, Sook-Young; Sok, Sohyune R


    The population of Korea is aging rapidly. The older population varies in characteristics in accordance with a wide-range of circumstances; therefore, categorizing the overall older population as a homogeneous group, could misrepresent their issues. For that reason, the study of older people should be focused on the diversity of characteristics among the older population. The aims of this study were to examine and identify the factors related to life satisfaction in older Korean women living alone. This study was a cross-sectional survey design. The participants comprised of 243 older women over the age of 65, who met eligibility criteria. Measures were a demographic characteristics form, the Health Self-Rating Scale, the Self-Esteem Scale (RSES), the Korean Geriatric Depression Scale Short Form, and the Life Satisfaction Instrument. Degrees of the perceived health status, self-esteem, and depression were higher than the median. Life satisfaction was lower than the median. Predictors that determine life satisfaction in older Korean women living alone were depression, perceived health status, self-esteem, and monthly allowance. All these predictors, or factors, had an explanatory power of 48.2% for life satisfaction among older Korean women living alone. Of all these predictor factors, depression had the largest impact. The major factor influencing the life satisfaction in older Korean women living alone was depression. These findings suggest that there is a need to develop nursing strategies aimed at decreasing depression in order to increase life satisfaction in older women living alone.

  8. Alcohol and associated characteristics among older persons living with human immunodeficiency virus on antiretroviral therapy. (United States)

    Williams, Emily C; Bradley, Katharine A; Balderson, Benjamin H; McClure, Jennifer B; Grothaus, Lou; McCoy, Katryna; Rittmueller, Stacey E; Catz, Sheryl L


    Alcohol use, and particularly unhealthy alcohol use, is associated with poor human immunodeficiency virus (HIV)-related outcomes among persons living with HIV (PLWH). Despite a rapidly growing proportion of PLWH ≥50 years, alcohol use and its associated characteristics are underdescribed in this population. The authors describe alcohol use, severity, and associated characteristics using data from a sample of PLWH ≥50 years who participated in a trial of a telephone-based intervention to improve adherence to antiretroviral therapy (ART). Participants were recruited from acquired immunodeficiency syndrome (AIDS) service organizations in 9 states and included PLWH ≥50 years who were prescribed ART, reported suboptimal adherence at screening (missing >1.5 days of medication or taking medications 2 hours early or late on >3 days in the 30 days prior to screening), and consented to participate. The AUDIT-C (Alcohol Use Disorders Identification Test-Consumption) alcohol screen, sociodemographic characteristics, substance use, and mental health comorbidity were assessed at baseline. AUDIT-C scores were categorized into nondrinking, low-level drinking, and mild-moderate unhealthy, and severe unhealthy drinking (0, 1-3, 4-6, and 7-12, respectively). Analyses described and compared characteristics across drinking status (any/none) and across AUDIT-C categories among drinkers. Among 447 participants, 57% reported drinking in the past year (35%, 15%, and 7% reported low-level drinking, mild-moderate unhealthy drinking, and severe unhealthy drinking, respectively). Any drinking was most common among men and those who were lesbian, gay, bisexual, or transgender (LGBT), married/partnered, had received past-year alcohol treatment, and never used injection drugs (P values all older PLWH with suboptimal ART adherence, a majority reported past-year alcohol use and 22% screened positive for unhealthy alcohol use. Any and unhealthy alcohol use were associated with demographics

  9. Traffic Safety of Older Drivers in Various Types of Road Intersections

    Directory of Open Access Journals (Sweden)

    Tomaž Tollazzi


    Full Text Available In industrialized countries people over 50 years of age represent a rapidly growing part of population. Their lifestyle is also becoming more active, which means that the percentage of older drivers in the population of all drivers is also increasing. Many different studies have shown that elderly drivers are more frequently involved in specific types of accidents, especially at intersections. In the past 15 years there was a trend of increasing popularity of roundabouts in Slovenia. Their introduction was generally supported by the arguments of increased traffic-flow capacity and traffic safety as well. The studies on which these arguments are based were performed with an “ideal” type of driver in mind; the one that fully understands new rules and reacts correctly in all situations that may occur at such intersections, where there are no light signals to guide them. An elderly person does not necessarily conform to that ideal and if the percentage of elderly drivers became significant, the premises of the above mentioned studies may not be correct anymore which in turn implies that their results could also be questioned. The present study concentrated on the evaluation of traffic safety of elderly drivers, at various types of intersection, from their own perspective. Various statistical analyses of obtained data were performed. The most important finding was that we may claim, with high degree of probability, that the average person of the age of over 60 feels more unsafe at double-lane roundabouts than they would feel had the same intersection been equipped with traffic lights. Elderly traffic participants will always cause more accidents or participate in them due to hazardous factors. Challenge, arising from many different studies and researches, is in studying what measures and solutions can reduce the risk for elderly participants.

  10. Internet use: Perceptions and experiences of visually impaired older adults

    Directory of Open Access Journals (Sweden)

    Patrick Emeka Okonji


    Full Text Available Many older people are increasingly using the internet. This study investigated the experiences of visually impaired older people on internet use and explored how it fits into their lives. 20 visually impaired older people aged 60 years and over were recruited from a voluntary organisation for blind people. Qualitative interviews were conducted with all participants to investigate how they perceive the relevance of internet use to their daily lives. Findings suggest that the internet not only has potential to promote their ability to perform daily tasks, cope with vision impairment and feel socially included. However, the rapid pace of technological advancement is feared as a development that could further widen the digital divide if they are not carried along by addressing barriers to their internet.

  13. Biofilm-growing intestinal anaerobic bacteria. (United States)

    Donelli, Gianfranco; Vuotto, Claudia; Cardines, Rita; Mastrantonio, Paola


    Sessile growth of anaerobic bacteria from the human intestinal tract has been poorly investigated, so far. We recently reported data on the close association existing between biliary stent clogging and polymicrobial biofilm development in its lumen. By exploiting the explanted stents as a rich source of anaerobic bacterial strains belonging to the genera Bacteroides, Clostridium, Fusobacterium, Finegoldia, Prevotella, and Veillonella, the present study focused on their ability to adhere, to grow in sessile mode and to form in vitro mono- or dual-species biofilms. Experiments on dual-species biofilm formation were planned on the basis of the anaerobic strains isolated from each clogged biliary stent, by selecting those in which a couple of anaerobic strains belonging to different species contributed to the polymicrobial biofilm development. Then, strains were investigated by field emission scanning electron microscopy and confocal laser scanning microscopy to reveal if they are able to grow as mono- and/or dual-species biofilms. As far as we know, this is the first report on the ability to adhere and form mono/dual-species biofilms exhibited by strains belonging to the species Bacteroides oralis, Clostridium difficile, Clostridium baratii, Clostridium fallax, Clostridium bifermentans, Finegoldia magna, and Fusobacterium necrophorum. © 2012 Federation of European Microbiological Societies.

    Manna Mônica Cecília Bochetti


    Full Text Available PURPOSE: To compare morphologically three different types of tracheotomy in growing rats, applying microsurgical technique. METHODS: EPM-1 Wistar growing rats (n=57 weighing 88gm and aged 35 days were randomized in four groups, according tracheotomy incision type (longitudinal, transverse and tracheal segment excision, and sham group. Following intramuscular anesthesia with ketamine and xylazine, the trachea was exposed and incised, according to the group, and a hand-made endotracheal cannula was inserted into the organ, under sterile conditions. This cannula was removed after 7 days, and animals have been sacrificed 30 days later. Tracheas samples were submitted to histological study, stained by hematoxylin-eosin and Masson trichrome, evaluating fibrosis, inflammatory infiltrate and epidermoid metaplasia. RESULTS: There was more frequency of inflammatory infiltrate at the tracheal epithelium in the tracheal segment excision group (87% compared to the longitudinal (40% and transverse (36% incision groups (p=0.009. Evaluating epidermoid metaplasia, tracheal segment excision and the longitudinal groups presented 33% and 40%, respectively, compared to 0% of the transverse group (p=0.03. Concerning to fibrosis, in a global comparison (p=0.1 among the three groups there was no difference, however, compared to the longitudinal group the transverse group showed lower level of fibrosis (p=0.04. Sham group did not present any relevant morphologic alterations and it was used as reference pattern. CONCLUSION: Taken together, our data show that tracheal segment excision promotes more epithelium aggression and transverse tracheal incision shows less morphologic alterations.

  15. Immunotoxicity of ochratoxin A to growing gilts. (United States)

    Harvey, R B; Elissalde, M H; Kubena, L F; Weaver, E A; Corrier, D E; Clement, B A


    Ochratoxin A (OA) was incorporated in the diets of growing gilts (mean body weight, 20.1 kg) at a concentration of 2.5 mg of OA/kg of feed and was fed continuously for 35 days. Humoral and cell-mediated immunologic measurements were evaluated to determine the effects of OA on immune function in swine. Cutaneous basophil hypersensitivity to phytohemagglutinin (PHA), delayed hypersensitivity to tuberculin, PHA-induced lymphocyte blastogenesis, interleukin-2 production, total and isotype immunoglobulin concentrations, antibody response to chicken RBC, and macrophage activation were used to evaluate immune function. Gilts treated with OA had reduced cutaneous basophil hypersensitivity response to PHA, reduced delayed hypersensitivity to tuberculin, decreased stimulation index for lymphoblastogenesis, decreased interleukin-2 production when lymphocytes were stimulated with concanavalin A, and decreased number and phagocytic activity of macrophages. Differences were not observed for total and isotype immunoglobulin concentrations, or humoral hemagglutination (chicken RBC) titer. These data indicate that OA may suppress cell-mediated immune response in growing swine.

    Full Text Available The objective of the experiment was to evaluate the light colour preference of growing rabbits placed in a free-choice cage. The experiment was carried out on 128 Pannon White growing rabbits weaned at the age of 5 weeks and placed into blocks (2m2 of four cages. The rabbits could move freely among the four cages (0.5m2 each through swing doors. The cages differed only in the colour of the light applied (white, yellow, green or blue. The lighting schedule was 16L: 8D. From 6 until 10 weeks of age, infrared video recording was performed once a week (24 hours. The number of rabbits in each cage was counted every 15 minutes. Feed consumption was measured weekly. Between 6 and 10 weeks of age the rabbits significantly preferred white light (28.0%. The preference order was the following: yellow (26.3%, blue (23.4% and green (22.3% (P<0.001. No significant differences were recorded in the feed consumption among the cages. In conclusion, the cage preference of the rabbits was slightly affected by the light colour.

  17. Effective communication with older adults. (United States)

    Daly, Louise


    Communication is an essential aspect of life, yet it can be taken for granted. Its centrality to being in the world and in professional practice often becomes evident when nurses and older adults encounter communication difficulties. The factors that can affect nurses' communication with older adults relate to the older adult, the nurse, sociocultural considerations and the environment, and the interactions between these factors. In adopting a person-centred approach to communicating with older adults, it is necessary to get to know the person as an individual and ensure communication meets their needs and abilities. Effective communication is essential in nursing practice and requires professional competence and engagement. This article can be used by nurses to support effective communication with older adults across the continuum of care.

  18. Dehydration in the Older Adult. (United States)

    Miller, Hayley J


    Dehydration affects 20% to 30% of older adults. It has a greater negative outcome in this population than in younger adults and increases mortality, morbidity, and disability. Dehydration is often caused by water deprivation in older adults, although excess water loss may also be a cause. Traditional markers for dehydration do not take into consideration many of the physiological differences present in older adults. Clinical assessment of dehydration in older adults poses different findings, yet is not always diagnostic. Treatment of dehydration should focus on prevention and early diagnosis before it negatively effects health and gives rise to comorbidities. The current article discusses what has most thoroughly been studied; the best strategies and assessment tools for evaluation, diagnosis, and treatment of dehydration in older adults; and what needs to be researched further.

  19. The Neuropsychological Function of Older First-Time Child Exploitation Material Offenders: A Pilot Study. (United States)

    Rodriguez, Marcelo; Ellis, Andrew


    Despite the growing incidence of child exploitation offences, there is little knowledge of the neuropsychological function of older child exploitation material offenders (CEMOs). Given that studies have reported that sex offenders demonstrate deficits attributed to frontal and temporal lobe function, the aim of this pilot study was to investigate the frontotemporal function of older first-time child exploitation material offenders (FTCEMOs). The neuropsychological performance of 11 older FTCEMOs was compared with 34 older historical sex offenders (HSOs) and 32 older nonsex offender (NSO) controls. Forty-five percent of FTCEMOs admitted to a pedophilic interest, which was significantly lower than those reported by HSOs. FTCEMOs provided significantly higher intellectual function scores than HSOs. Results revealed no evidence of mild or major neurocognitive disorder in FTCEMOs. Although the groups were not significantly different, compared with normative data, FTCEMOs reported a high incidence of impairment on a measure of decision making and on a measure of facial emotional recognition.

  20. Health Equity and Aging of Bisexual Older Adults: Pathways of Risk and Resilience. (United States)

    Fredriksen-Goldsen, Karen I; Shiu, Chengshi; Bryan, Amanda E B; Goldsen, Jayn; Kim, Hyun-Jun


    Bisexual older adults are a growing yet largely invisible, underserved, and understudied population. Utilizing the Health Equity Promotion Model, we examined hypothesized mechanisms accounting for health disparities between bisexual older adults and lesbian and gay older adults. Based on data from Caring and Aging with Pride, the largest national survey of LGBT older adults, this study (N = 2,463) utilized structural equation modeling to investigate direct and indirect associations between sexual identity (bisexual vs. lesbian and gay) and health via sexual identity factors (identity disclosure and internalized stigma), social resources, and socioeconomic status (SES). Bisexual older adults reported significantly poorer health compared with lesbian and gay older adults. Indirect effects involving sexual identity factors, social resources, and SES explained the association between bisexual identity and poorer health. A potentially protective pathway was also identified wherein bisexuals had larger social networks after adjusting for other factors. Bisexual older adults face distinct challenges and health risks relative to other older adults, likely because of the accumulation of socioeconomic and psychosocial disadvantages across the life course. Interventions taking into account older bisexuals' unique risk and protective factors may be helpful in reducing health inequities.

    Full Text Available In the process of health transition, India is facing rapid pace of demographic aging. Rapid increase in older adult population posed serious concerns regarding health and health care utilization for them. However, very limited research documented resultant implications of demographic aging for health and health care use in the nexus of marital status and gender. With this perspective, the present study examined patterns in morbidity prevalence and health seeking behaviour among older widows in India. Multivariate logistic regression models were estimated to examine the effects of socio-demographic conditions on morbidity prevalence among older widows and their health care seeking behavior. Data from the latest 60(th round of National Sample Survey (NSS, 2004 was used. Overall, morbidity prevalence was 13% greater among older widows compared to older widowers. Adjusted prevalence of communicable and non-communicable diseases was found 74 and 192 per 1000 older widows respectively. At the same time, likelihood of seeking health care services for reported morbidities was substantially lower among older widows. The findings of this study are important to support policy makers and health care providers in identifying individuals 'at risk' and could be integrated into the current programs of social, economic and health security for the older persons.

    Full Text Available A learning organization has a deep culture of learning. It is constantly encourage its member to learn. This learning activity is not only for adapting to the rapid changing of its internal and external environment, but also for growing. The effort of a learning organization to create a conducive learning climate can be indicated by training its members. Working towards a learning organization has both its strengths and drawbacks. The strengths are it can improve the organization performance and organization survival. However, learning too rapid can lead to learning stress. Moreover it can lead to harsh internal competition.

  3. Patient Portal Use and Experience Among Older Adults: Systematic Review. (United States)

    Sakaguchi-Tang, Dawn K; Bosold, Alyssa L; Choi, Yong K; Turner, Anne M


    The older adult population (65 years or older) in the United States is growing, and it is important for communities to consider ways to support the aging population. Patient portals and electronic personal health records (ePHRs) are technologies that could better serve populations with the highest health care needs, such as older adults. The aim of this study was to assess the existing research landscape related to patient portal and ePHR use and experience among older adults and to understand the benefits and barriers to older adults' use and adoption of patient portals and ePHRs. We searched six pertinent bibliographic databases for papers, published from 2006 to 2016 and written in English, that focused on adults 60 years or older and their use of or experience with patient portals or ePHRs. We adapted preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines to review papers based on exclusion and inclusion criteria. We then applied thematic analysis to identify key themes around use, experience, and adoption. We retrieved 199 papers after an initial screening and removal of duplicate papers. Then we applied an inclusion and exclusion criteria, resulting in a final set of 17 papers that focused on 15 separate projects. The majority of papers described studies involving qualitative research, including interviews and focus groups. They looked at the experience and use of ePHRs and patient portals. Overall, we found 2 main barriers to use: (1) privacy and security and (2) access to and ability to use technology and the Internet. We found 2 facilitators: (1) technical assistance and (2) family and provider advice. We also reported on older adults' experience, including satisfaction with the system and improvement of the quality of their health care. Several studies captured features that older adults wanted from these systems such as further assistance managing health-related tasks and contextual health advice and tips. More research is

  4. Elastic plastic analysis of growing cracks

    Energy Technology Data Exchange (ETDEWEB)

    Rice, J R; Drugan, W J; Sham, T L


    The elastic--plastic stress and deformation fields at the tip of a crack which grows in an ideally plastic solid under plane strain, shows small scale yielding conditions. Results of an asymptotic analysis suggests the existence of a crack tip stress state similar to that of the classical Prandtl field, but containing a zone of elastic unloading between the centered fan region and the trailing constant stress plastic region. The near tip expression for the rate of opening displacement delta at distance r from the growing tip is found to have the form delta-. = ..cap alpha.. J-./sigma/sub o/ + ..beta..(sigma/sub o//E) a-. ln(R/r) but the presence of the elastic wedge causes ..beta.. to have the revised value of 5.08 (for Poisson ratio = 0.3); also, (a = crack length, sigma/sub o/ = yield strength, E = elastic modulus, and J denotes the far-field value), and ( 2/)K/sup 2//E for the small scale yielding conditions considered. The parameters ..cap alpha.. and R cannot be determined from the asymptotic analysis, but comparisons with finite element solutions suggest that, for small amounts of growth, ..cap alpha.. is approximately the same for stationary and growing cracks, and R scales approximately with the size of the plastic zone, being about 15% to 30% larger. For large scale yielding, a similar form applies with possible variations in ..cap alpha.. and ..beta.., in cases which maintain triaxial constraint at the crack tip. In the fully yielded case R is expected to be proportional to the dimension of the uncracked ligament. Model crack growth criterion requiring a critical delta at some fixed r from the tip, is re-examined in light of the more accurate solution. Results suggest that the J versus relation describing growth is dependent on the extent of yielding. It is suggested that this dependency might be small for highly ductile materials, provided that a similar triaxial constraint is maintained in all cases.

  5. Rapid small lot manufacturing

    Energy Technology Data Exchange (ETDEWEB)

    Harrigan, R.W.


    The direct connection of information, captured in forms such as CAD databases, to the factory floor is enabling a revolution in manufacturing. Rapid response to very dynamic market conditions is becoming the norm rather than the exception. In order to provide economical rapid fabrication of small numbers of variable products, one must design with manufacturing constraints in mind. In addition, flexible manufacturing systems must be programmed automatically to reduce the time for product change over in the factory and eliminate human errors. Sensor based machine control is needed to adapt idealized, model based machine programs to uncontrolled variables such as the condition of raw materials and fabrication tolerances.

Among the numerous tested products, short chain fatty acids stimulated intestinal mucus production at different level and intestinal cells proliferation in rats (Meslin et al., 2001; Moreau et al., 2003. Short and medium chain fatty acids could also modulate intestinal microflora: in rabbits, the antimicrobial activity of caprilic and capric acids was proved on various strains of Clostridium perfringens and Escherichia coli (Marounek et al., 2002. The present trial aimed to evaluate the effect of butyrate inclusion and level on growth performance, health status, digestive physiology and slaughter traits in growing rabbits.

  7. Morphogenesis of filaments growing in flexible confinements (United States)

    Vetter, R.; Wittel, F. K.; Herrmann, H. J.


    Space-saving design is a requirement that is encountered in biological systems and the development of modern technological devices alike. Many living organisms dynamically pack their polymer chains, filaments or membranes inside deformable vesicles or soft tissue-like cell walls, chorions and buds. Surprisingly little is known about morphogenesis due to growth in flexible confinements—perhaps owing to the daunting complexity lying in the nonlinear feedback between packed material and expandable cavity. Here we show by experiments and simulations how geometric and material properties lead to a plethora of morphologies when elastic filaments are growing far beyond the equilibrium size of a flexible thin sheet they are confined in. Depending on friction, sheet flexibility and thickness, we identify four distinct morphological phases emerging from bifurcation and present the corresponding phase diagram. Four order parameters quantifying the transitions between these phases are proposed.

    Full Text Available The paper presents trends in economic growth and development in twelve least developed countries from 2006 to 2015. The study is based on the data retrieved from the World Bank Database. During the analysed 10 years, seven Asian (Myanmar, Lao PDR, Bhutan, Cambodia, Timor-Leste, Bangladesh, and Afghanistan and five African (Ethiopia, Rwanda, Angola, Sudan, and Mozambique LDCs had average annual GDP per capita growth rates higher than 4.0%. GDP has been largely generated through the services and industry sectors. A few LDCs sustained strong growth mainly because of foreign assistance and in other countries remittances were a significant source of development finance. Resource rich countries recorded high inflows of foreign direct investment. In a few fast growing LDCs the state has been heavily engaged in economy. The analysed LDCs substantially improved their development indicators.

  9. Feed efficiency metrics in growing pigs. (United States)

    Calderón Díaz, J A; Berry, D P; Rebeiz, N; Metzler-Zebeli, B U; Magowan, E; Gardiner, G E; Lawlor, P G


    The objective of the present study was to quantify the interrelationships between different feed efficiency measures in growing pigs and characterize pigs divergent for a selection of these measures. The data set included data from 311 growing pigs between 42 and 91 d of age from 3 separate batches. Growth-related metrics available included midtest metabolic BW (BW), energy intake (EI), and ADG. Ratio efficiency traits included energy conversion ratio (ECR), Kleiber ratio (ADG/BW), relative growth rate (RGR), residual EI (REI), and residual daily gain (RDG). Residual intake and gain (RIG; i.e., a dual index of both REI and RDG) and residual midtest metabolic weight (RMW) were also calculated. Simple Pearson correlations were estimated between the growth and feed efficiency metrics. In litters with at least 3 pigs of each sex, pigs were separately stratified on each residual trait as high, medium, and low rank. Considerable interanimal variability existed in all metrics evaluated. Male pigs were superior to females for all metrics ( efficiency metrics improved as birth BW increased ( efficiency metrics were strong to moderate ( efficient) had lower EI and ECR and were superior for RIG ( efficient) had greater BW gain and better ECR ( Energy conversion ratio, REI, and RIG were superior ( efficient) compared with medium-RMW pigs. High-RIG pigs (i.e., more efficient) had lower EI ( efficiency traits investigated in this study were different from unity, indicating that each trait is depicting a different aspect of efficiency in pigs, although the moderate to strong correlations suggest that improvement in one trait would, on average, lead to improvements in the others. Pigs ranked as more efficient on residual traits such as REI consumed less energy for a similar BW gain, which would translate into an economic benefit for pig producers.

    The American Society of Clinical Oncology (ASCO) convened a subcommittee to develop recommendations on improving the evidence base for treating older adults with cancer in response to a critical need identified by the Institute of Medicine. Older adults experience the majority of cancer diagnoses and deaths and make up the majority of cancer survivors. Older adults are also the fastest growing segment of the US population. However, the evidence base for treating this population is sparse, because older adults are underrepresented in clinical trials, and trials designed specifically for older adults are rare. The result is that clinicians have less evidence on how to treat older adults, who represent the majority of patients with cancer. Clinicians and patients are forced to extrapolate from trials conducted in younger, healthier populations when developing treatment plans. This has created a dearth of knowledge regarding the risk of toxicity in the average older patient and about key end points of importance to older adults. ASCO makes five recommendations to improve evidence generation in this population: (1) Use clinical trials to improve the evidence base for treating older adults with cancer, (2) leverage research designs and infrastructure for generating evidence on older adults with cancer, (3) increase US Food and Drug Administration authority to incentivize and require research involving older adults with cancer, (4) increase clinicians' recruitment of older adults with cancer to clinical trials, and (5) use journal policies to improve researchers' reporting on the age distribution and health risk profiles of research participants. © 2015 by American Society of Clinical Oncology.

  15. Effect of imipenem and sulbactam on sessile cells of Acinetobacter baumannii growing in biofilm. (United States)

    Vidal, R; Dominguez, M; Urrutia, H; Bello, H; Garcia, A; Gonzalez, G; Zemelman, R


    The effect of the age of biofilms formed by Acinetobacter baumannii on the activity of sulbactam and imipenem on sessile cells was investigated. Against cells of young biofilms both antibiotics were rapidly bactericidal. As the biofilm aged, sulbactam lost most of its activity, but imipenem continued to be bactericidal to some extent. This fact probably reflects the ability of imipenem to exert bactericidal activity on slow-growing bacteria.

    Yoonseock LEE


    Full Text Available This paper examines the evolving state of employment of older Japanese people. Since the rapid increase in population aging, employment options, such as re-employment, are favored over infexible retirement age extension. In order to meet these needs, the Japanese government has created new employment policies. This study shows newer models for the re-employment of the aging population in Japan. Specifcally, it shows that employment practices promoting balance between fexibility and security (i.e., fexicurity provide successful alternatives to the re-employment of older people. Data are drawn from longitudinal research on employment con-ditions among older people conducted by the Japanese government. Using this data, the prob-ability of being employed and wage rate is ana-lyzed, including the degree of change that each factor has on the probability of older people being employed. Results indicate that super-aged soci-eties, like Japan, should promote labor markets that balance fexibility and security for re-employ-ing older people.

  20. Older Adults’ Coping with the Digital Everyday Life

    Directory of Open Access Journals (Sweden)

    Wenche M. Rønning


    Full Text Available This study was motivated by a concern for how older adults adjust to their digital everyday life. Theories of motivation and self-efficacy are applied in order to understand how older adults master and adjust to the rapid development into a paper-free, online world. A sample of eighteen older adults (62-90 years were interviewed about the reasons and motivations underlying their ICT usage, and how this affects their perception of mastering their everyday life. A semi-structured interview guide was developed for this purpose. The data were analyzed using an inductive coding procedure involving descriptive and interpretive phases based on the theoretical assumptions about motivation and mastery. Three overarching categories were evident in the data material; Challenges, Connectedness and Expanding. The first category describes new challenges mastering everyday life activities, and how this brings about feelings of pressure, barriers, and fear. The other two categories give a more positive picture of how older adults perceive the new developments. Internet and social media is perceived as positive because it enables them to stay connected to family, old and new friends. It also enables them to cultivate and expand leisure and hobby activities in new ways. Based on the findings we underscore the necessity of devising strategies that will prevent older people from being marginalized in relation to the digital everyday life.

  1. Multidimensional Attitudes of Emergency Medicine Residents Toward Older Adults

    Directory of Open Access Journals (Sweden)

    Teresita M. Hogan


    Full Text Available Introduction: The demands of our rapidly expanding older population strain many emergency departments (EDs, and older patients experience disproportionately high adverse health outcomes. Trainee attitude is key in improving care for older adults. There is negligible knowledge of baseline emergency medicine (EM resident attitudes regarding elder patients. Awareness of baseline attitudes can serve to better structure training for improved care of older adults. The objective of the study is to identify baseline EM resident attitudes toward older adults using a validated attitude scale and multidimensional analysis. Methods: Six EM residencies participated in a voluntary anonymous survey delivered in summer and fall 2009. We used factor analysis using the principal components method and Varimax rotation, to analyze attitude interdependence, translating the 21 survey questions into 6 independent dimensions. We adapted this survey from a validated instrument by the addition of 7 EM-specific questions to measures attitudes relevant to emergency care of elders and the training of EM residents in the geriatric competencies. Scoring was performed on a 5-point Likert scale. We compared factor scores using student t and ANOVA. Results: 173 EM residents participated showing an overall positive attitude toward older adults, with a factor score of 3.79 (3.0 being a neutral score. Attitudes trended to more negative in successive post-graduate year (PGY levels. Conclusion: EM residents demonstrate an overall positive attitude towards the care of older adults. We noted a longitudinal hardening of attitude in social values, which are more negative in successive PGY-year levels. [West J Emerg Med. 2014;15(4:511–517.

    Water availability is a major limitation for agricultural productivity. Plants growing in severe arid climates such as deserts provide tools for studying plant growth and performance under extreme drought conditions. The perennial species Calotropis procera used in this study is a shrub growing in many arid areas which has an exceptional ability to adapt and be productive in severe arid conditions. We describe the results of studying the metabolomic response of wild C procera plants growing in the desert to a one time water supply. Leaves of C. procera plants were taken at three time points before and 1 hour, 6 hours and 12 hours after watering and subjected to a metabolomics and lipidomics analysis. Analysis of the data reveals that within one hour after watering C. procera has already responded on the metabolic level to the sudden water availability as evidenced by major changes such as increased levels of most amino acids, a decrease in sucrose, raffinose and maltitol, a decrease in storage lipids (triacylglycerols) and an increase in membrane lipids including photosynthetic membranes. These changes still prevail at the 6 hour time point after watering however 12 hours after watering the metabolomics data are essentially indistinguishable from the prewatering state thus demonstrating not only a rapid response to water availability but also a rapid response to loss of water. Taken together these data suggest that the ability of C. procera to survive under the very harsh drought conditions prevailing in the desert might be associated with its rapid adjustments to water availability and losses.

    Nestler, R.B.; Llewellyn, L.; Benner, M.


    Two experiments, using 784 bobwhite quail chicks, were conducted at the Patuxent Research Refuge, Bowie, Maryland, to find a growing diet that would meet wartime restrictions. In 1941 a diet containing 14 per cent sardine fish meal was formulated and gave satisfactory results from the standpoints of survival and growth. Since fish meal now is scarce, search was made for a diet without war-restricted commodities yet equal to the above-mentioned diet in feeding value. Ten diets were compared.....In the present experiments, quail fed this same diet modified by the substitution of 0.12 per cent of D-activated sterol for vitamin A and D feeding oil fortified showed the highest survival and the best live weights at the end of both the sixth and tenth weeks. They also were among the top three groups in requiring the least quantity of feed per unit of gain in weight; however, they consumed the greatest quantity of feed.....Of the other nine diets, that which seemed most promising, considering survival, live weight, and efficiency of feed utilization, was as follows (parts by weight) : Yellow corn, ground 26.08...Millet, ground 10.00...Alfalfa leaf meal, dehydrated 7.50...Soybean oil meal, solvent-processed 50.00...Dried whey 3.00...Special steamed bonemeal 1.50...Limestone, ground 0.80...Salt mixture 1.OO...D-activated animal sterol 0.12....100.00.....At the end of ten weeks the results on this diet (Diet l l ) , as compared with that containing sardine meal (Diet 23), were as follows: Diet No. 11 Percentage survival 71, Average live weight per bird, grams 144,....Growing mash consumed, per bird-day, grams 6.8 Feed consumed per gram of gain in weight (grams) 3.8......Diet 23....Percentage survival, 80,...Avg live weight per bird, grams....145,....Growing mash consumed , per bird-day, grams...7.4...Feed consumed per gram of gain in weight (grams)....3.9.

  8. The growing need for microservices in bioinformatics

    Directory of Open Access Journals (Sweden)

    Christopher L Williams


    Full Text Available Objective: Within the information technology (IT industry, best practices and standards are constantly evolving and being refined. In contrast, computer technology utilized within the healthcare industry often evolves at a glacial pace, with reduced opportunities for justified innovation. Although the use of timely technology refreshes within an enterprise′s overall technology stack can be costly, thoughtful adoption of select technologies with a demonstrated return on investment can be very effective in increasing productivity and at the same time, reducing the burden of maintenance often associated with older and legacy systems. In this brief technical communication, we introduce the concept of microservices as applied to the ecosystem of data analysis pipelines. Microservice architecture is a framework for dividing complex systems into easily managed parts. Each individual service is limited in functional scope, thereby conferring a higher measure of functional isolation and reliability to the collective solution. Moreover, maintenance challenges are greatly simplified by virtue of the reduced architectural complexity of each constitutive module. This fact notwithstanding, rendered overall solutions utilizing a microservices-based approach provide equal or greater levels of functionality as compared to conventional programming approaches. Bioinformatics, with its ever-increasing demand for performance and new testing algorithms, is the perfect use-case for such a solution. Moreover, if promulgated within the greater development community as an open-source solution, such an approach holds potential to be transformative to current bioinformatics software development. Context: Bioinformatics relies on nimble IT framework which can adapt to changing requirements. Aims: To present a well-established software design and deployment strategy as a solution for current challenges within bioinformatics Conclusions: Use of the microservices framework

  9. Pharmaceutical Industry in Vietnam: Sluggish Sector in a Growing Market

    Directory of Open Access Journals (Sweden)

    Antonio Angelino


    Full Text Available Vietnam is a fast growing economy in the Asian region with a significantly high population (over 92 million in 2015. Although still expanding (about 1.1% on average during 2000–2015, the Vietnamese population is considered to be entering the ageing stage at a very high rate. The rapid expansion of the middle-income urban class and the ageing people ratio have dramatically pushed up the demand for healthcare goods, particularly in terms of pharmaceutical products. Since the early 1990s the government has addressed the necessities of rising demand for healthcare products by formulating a series of policies aimed at promoting the development of the pharmaceutical industry. However, the implementation of such policies does not seem to have been completely efficient given that the country still needs to import up to 90% of its pharmaceutical consumption. This paper aims to explore the development of the pharmaceutical industry during the years 1990–2015 and to identify a series of weaknesses in the government promotion of the industry. Future developments will also be discussed on how the Vietnamese pharmaceutical industry could increase its participation in the regional supply chain, which is currently being dominated by big players like India and China.

  19. A Survey of Georgia Adult Protective Service Staff: Implications for Older Adult Injury Prevention and Policy

    Directory of Open Access Journals (Sweden)

    Strasser, Sheryl


    Full Text Available Background: The aging population is a rapidly growing demographic. Isolation and limited autonomy render many of the elderly vulnerable to abuse, neglect and exploitation. As the population grows, so does the need for Adult Protective Services (APS. This study was conducted to examine current knowledge of older adult protection laws in Georgia among APS staff and to identify training opportunities to better prepare the APS workforce in case detection and intervention.Methods: The Georgia State University Institute of Public Health faculty developed a primary survey in partnership with the Georgia Division of Aging Services’ leadership to identify key training priority issues for APS caseworkers and investigators. A 47-item electronic questionnaire was delivered to all APS employees via work-issued email accounts. We conducted descriptive analyses, t-tests and chi-square analyses to determine APS employees’ baseline knowledge of Georgia’s elder abuse policies, laws and practices, as well as examine associations of age, ethnicity, and educational attainment with knowledge. We used a p-value of 0.05 and 95% confidence intervals to determine statistical significance of analyses performed.Result: Ninety-two out of 175 APS staff responded to the survey (53% response rate. The majority of respondents were Caucasian (56% women (92%. For over half the survey items, paired sample t-tests revealed significant differences between what APS staff reported as known and what APS staff members indicated they needed to know more about in terms of elder abuse and current policies. Chi-square tests revealed that non-Caucasians significantly preferred video conferencing as a training format (44% compared to 18%, [χ2(1 = 7.102, p < .008], whereas Caucasians preferred asynchronous online learning formats (55% compared to 28% [χ2(1 =5.951, p < .015].Conclusion: Results from this study provide the Georgia Division of Aging with insight into specific policy areas

  20. Growing pains: twelve lessons from corporate restructuring. (United States)

    Gill, S L; Johnson, R L


    Corporate reorganization is a realignment of resources to enhance competitive strength and can follow one of two lines, vertical or horizontal. Whichever strategy is used, the reason for it remains unchanged: to provide a structural hierarchy through which strategic market niches are acquired and resources are economically deployed throughout the system. Healthcare corporate restructuring, however, is encountering growing pains, some of which were inevitable and others avoidable. When the healthcare organizational landscape is surveyed, 12 lessons can be learned about corporate reorganization: 1. Reorganization should be based on anticipated market and environmental conditions. 2. Form follows function. 3. Interdependence among multiple corporate units must be clearly acknowledged. 4. Reorganization is much more costly and politically charged than it appears at first. Reserved rights must be clearly defined. 6. The purpose and composition of the parent governing board must be distinguished from those of subsidiary boards. 7. Clarification of roles and relationships between the parent and subsidiaries is critical. 8. Unrealistic expectations of success should be confronted through up-front planning, negotiation, and creative problem solving. 9. False assumptions about corporate staffing needs create internal system warfare. 10. Physician support is crucial for success. 11. Hospital-based management skills and understanding may be inadequate for making personnel decisions in subsidiaries other than the hospital. 12. Competitive strategies must be strategically determined and must not be taken gamesmanship.

  1. Autoethnography in Health Research: Growing Pains? (United States)

    Chang, Heewon


    Autoethnography is gaining acceptance as a legitimate research method in health science research. The growing volume of published autoethnographies is indicative of this trend. After discussing the methodological tenents of this qualitative research method and its compatibility with health-related research, the author illustrates this trend with examples of published autoethnogrpahic books, theses, and journal articles. While celebrating the potential of autoethnography as a suitable health research method, the author critiques dominatly descriptive and evocative illness self-narratives that may evoke emontionally compelling responses from readers but offer insufficient sociocultural insights about the illness phenomenon. To identify a "desirable" autoethnography that provides not only a "thick description" of personal experiences but also a sociocultural interpration of such experiences, the author recommends both creators and consumers of autoethnography to ask five evaluative questions: (1) Does the autoethnography use authentic and trustworthy data?; (2) Does the autoethnography follow a reliable research process and show the process clearly?; (3) Does the autoethnography follow ethical steps to protect the rights of self and others presented and implicated in the autoethnography?; (4) Does the autoethnography analyze and interpret the sociocultural meaning of the author's personal experiences?; and (5) Does the autoethnography attempt to make a scholarly contribution with its conclusion and engagement of the existing literature? © The Author(s) 2016.

  2. Growing duckweed for biofuel production: a review. (United States)

    Cui, W; Cheng, J J


    Duckweed can be utilised to produce ethanol, butanol and biogas, which are promising alternative energy sources to minimise dependence on limited crude oil and natural gas. The advantages of this aquatic plant include high rate of nutrient (nitrogen and phosphorus) uptake, high biomass yield and great potential as an alternative feedstock for the production of fuel ethanol, butanol and biogas. The objective of this article is to review the published research on growing duckweed for the production of the biofuels, especially starch enrichment in duckweed plants. There are mainly two processes affecting the accumulation of starch in duckweed biomass: photosynthesis for starch generation and metabolism-related starch consumption. The cost of stimulating photosynthesis is relatively high based on current technologies. Considerable research efforts have been made to inhibit starch degradation. Future research need in this area includes duckweed selection, optimisation of duckweed biomass production, enhancement of starch accumulation in duckweeds and use of duckweeds for production of various biofuels. © 2014 German Botanical Society and The Royal Botanical Society of the Netherlands.

    Medical and surgical breakthroughs in the care of children born with heart defects have generated a growing population of adult survivors and spawned a new subspecialty of cardiology: adult congenital heart disease. The prevalence of adult congenital heart disease is escalating at a rampant rate, outpacing the relatively static prevalence of pediatric congenital heart disease, because adults now surpass children in numbers by a ratio of 2:1. As such, congenital heart disease can no longer be considered primarily a pediatric specialty. Most congenital heart defects are not curable and require lifelong specialized care. Health care systems worldwide are challenged to meet the unique needs of this increasingly complex patient population, including the development of supraregional centres of excellence to provide comprehensive and multidisciplinary specialized care. In this review, we explore the incidence and prevalence of congenital heart disease and their changing patterns, address organization and delivery of care, highlight the importance of appropriate training and dedicated research, summarize the high burden of health care resource utilization, and provide an overview of common issues encountered in adults with congenital heart disease.

  4. Bioaugmentation in growing plants for lunar bases (United States)

    Zaets, I.; Burlak, O.; Rogutskyy, I.; Vasilenko, A.; Mytrokhyn, O.; Lukashov, D.; Foing, B.; Kozyrovska, N.


    Microorganisms may be a key element in a precursory scenario of growing pioneer plants for extraterrestrial exploration. They can be used for plant inoculation to leach nutritional elements from regolith, to alleviate lunar stressors, as well as to decompose both lunar rocks and the plant straw in order to form a protosoil. Bioleaching capacities of both French marigold (Tagetes patula L.) and the associated bacteria in contact with a lunar rock simulant (terrestrial anorthosite) were examined using the model plant-bacteria microcosms under controlled conditions. Marigold accumulated K, Na, Fe, Zn, Ni, and Cr at higher concentrations in anorthosite compared to the podzol soil. Plants inoculated with the consortium of well-defined species of bacteria accumulated higher levels of K, Mg, and Mn, but lower levels of Ni, Cr, Zn, Na, Ca, Fe, which exist at higher levels in anorthosite. Bacteria also affected the Са/Mg and Fe/Mn ratios in the biomass of marigold grown on anorthosite. Despite their growth retardation, the inoculated plants had 15% higher weight on anorthosite than noninoculated plants. The data suggest that the bacteria supplied basic macro-and microelements to the model plant.

  5. Growing Bacteriophage M13 in Liquid Culture. (United States)

    Green, Michael R; Sambrook, Joseph


    Stocks of bacteriophage M13 are usually grown in liquid culture. The infected bacteria do not lyse but, instead, grow at a slower than normal rate to form a dilute suspension. The inoculum of bacteriophage is almost always a freshly picked plaque or a suspension of bacteriophage particles obtained from a single plaque, as described here. Infected cells contain up to 200 copies of double-stranded, replicative-form DNA and extrude several hundred bacteriophage particles per generation. Thus, a 1-mL culture of infected cells can produce enough double-stranded viral DNA (1-2 mg) for restriction mapping and recovery of cloned DNA inserts and sufficient single-stranded DNA (∼5-10 mg) for site-directed mutagenesis, DNA sequencing, or synthesis of radiolabeled probes. The titer of bacteriophages in the supernatant from infected cells is so high (∼10(12) pfu/mL) that a small aliquot serves as a permanent stock of the starting plaque. © 2017 Cold Spring Harbor Laboratory Press.

  6. The Growing Regulation of Conversion Therapy. (United States)

    Drescher, Jack; Schwartz, Alan; Casoy, Flávio; McIntosh, Christopher A; Hurley, Brian; Ashley, Kenneth; Barber, Mary; Goldenberg, David; Herbert, Sarah E; Lothwell, Lorraine E; Mattson, Marlin R; McAfee, Scot G; Pula, Jack; Rosario, Vernon; Tompkins, D Andrew


    Conversion therapies are any treatments, including individual talk therapy, behavioral (e.g. aversive stimuli), group therapy or milieu (e.g. "retreats or inpatient treatments" relying on all of the above methods) treatments, which attempt to change an individual's sexual orientation from homosexual to heterosexual. However these practices have been repudiated by major mental health organizations because of increasing evidence that they are ineffective and may cause harm to patients and their families who fail to change. At present, California, New Jersey, Oregon, Illinois, Washington, DC, and the Canadian Province of Ontario have passed legislation banning conversion therapy for minors and an increasing number of US States are considering similar bans. In April 2015, the Obama administration also called for a ban on conversion therapies for minors. The growing trend toward banning conversion therapies creates challenges for licensing boards and ethics committees, most of which are unfamiliar with the issues raised by complaints against conversion therapists. This paper reviews the history of conversion therapy practices as well as clinical, ethical and research issues they raise. With this information, state licensing boards, ethics committees and other regulatory bodies will be better able to adjudicate complaints from members of the public who have been exposed to conversion therapies.

    McKeigue, J.; Da Cunha, A.; Severino, D. [Global Business Reports (United States)


    Turkey's growing power market has attracted investors and project developers for over a decade, yet their plans have been dashed by unexpected political or financial crises or, worse, obstructed by a lengthy bureaucratic approval process. Now, with a more transparent retail electricity market, government regulators and investors are bullish on Turkey. Is Turkey ready to turn the power on? This report closely examine Turkey's plans to create a power infrastructure capable of providing the reliable electricity supplies necessary for sustained economic growth. It was compiled with on-the-ground research and extensive interview with key industrial and political figures. Today, hard coal and lignite account for 21% of Turkey's electricity generation and gas-fired plants account for 50%. The Alfin Elbistan-B lignite-fired plant has attracted criticism for its lack of desulfurization units and ash dam facilities that have tarnished the industry's image. A 1,100 MW hard-coal fired plant using supercritical technology is under construction. 9 figs., 1 tab.

  10. Diabetes mellitus in older adults. (United States)

    Mooradian, Arshag D; Chehade, Joe M


    The prevalence of diabetes mellitus increases with age and causes significant morbidity and poor quality of life in older adults. To review the current literature on the diagnosis and management of diabetes in the elderly, the relevant manuscripts were identified through a MEDLINE (2000-September 1, 2010) search of the English literature. The key phrase used was diabetes in older adults or diabetes in the elderly. The literature search was limited to core clinical journals that have accessible full texts. A total of 480 manuscripts were reviewed. Managing diabetes in older adults is a challenging task. Some features of the disease are unique to the older patient. Several new antidiabetic agents are now available for clinical use, and yet very few clinical trials have been carried out in this age group. For many older adults, maintaining independence is more important than adherence to published guidelines to prevent diabetes complications. The goals of diabetes care in older adults are to enhance quality of life without subjecting the residents to inappropriate interventions.

  12. Rapid Detection of Pathogens

    Energy Technology Data Exchange (ETDEWEB)

    David Perlin


    Pathogen identification is a crucial first defense against bioterrorism. A major emphasis of our national biodefense strategy is to establish fast, accurate and sensitive assays for diagnosis of infectious diseases agents. Such assays will ensure early and appropriate treatment of infected patients. Rapid diagnostics can also support infection control measures, which monitor and limit the spread of infectious diseases agents. Many select agents are highly transmissible in the early stages of disease, and it is critical to identify infected patients and limit the risk to the remainder of the population and to stem potential panic in the general population. Nucleic acid-based molecular approaches for identification overcome many of the deficiencies associated with conventional culture methods by exploiting both large- and small-scale genomic differences between organisms. PCR-based amplification of highly conserved ribosomal RNA (rRNA) genes, intergenic sequences, and specific toxin genes is currently the most reliable approach for bacterial, fungal and many viral pathogenic agents. When combined with fluorescence-based oligonucleotide detection systems, this approach provides real-time, quantitative, high fidelity analysis capable of single nucleotide allelic discrimination (4). These probe systems offer rapid turn around time (<2 h) and are suitable for high throughput, automated multiplex operations that are critical for clinical diagnostic laboratories. In this pilot program, we have used molecular beacon technology invented at the Public health Research Institute to develop a new generation of molecular probes to rapidly detect important agents of infectious diseases. We have also developed protocols to rapidly extract nucleic acids from a variety of clinical specimen including and blood and tissue to for detection in the molecular assays. This work represented a cooperative research development program between the Kramer-Tyagi/Perlin labs on probe development

  13. Tiber Personal Rapid Transit

    Full Text Available The project “Tiber Personal Rapid Transit” have been presented by the author at the Rome City Vision Competition1 2010, an ideas competition, which challenges architects, engineers, designers, students and creatives individuals to develop visionary urban proposals with the intention of stimulating and supporting the contemporary city, in this case Rome. The Tiber PRT proposal tries to answer the competition questions with the definition of a provocative idea: a Personal Rapid transit System on the Tiber river banks. The project is located in the central section of the Tiber river and aims at the renewal of the river banks with the insertion of a Personal Rapid Transit infrastructure. The project area include the riverbank of Tiber from Rome Transtevere RFI station to Piazza del Popolo, an area where main touristic and leisure attractions are located. The intervention area is actually no used by the city users and residents and constitute itself a strong barrier in the heart of the historic city.

  14. Review of Public Transport Needs of Older People in European Context. (United States)

    Shrestha, B P; Millonig, A; Hounsell, N B; McDonald, M


    People's life expectancy is increasing throughout the world as a result of improved living standards and medical advances. The natural ageing process is accompanied by physiological changes which can have significant consequences for mobility. As a consequence, older people tend to make fewer journeys than other adults and may change their transport mode. Access to public transport can help older people to avail themselves of goods, services, employment and other activities. With the current generation of older people being more active than previous generations of equivalent age, public transport will play a crucial role in maintaining their active life style even when they are unable to drive. Hence, public transport is important to older people's quality of life, their sense of freedom and independence. Within the European Commission funded GOAL (Growing Older and staying mobile) project, the requirements of older people using public transport were studied in terms of four main issues: Affordability, availability, accessibility and acceptability. These requirements were then analysed in terms of five different profiles of older people defined within the GOAL project - 'Fit as a Fiddle', 'Hole in the Heart', 'Happily Connected', An 'Oldie but a Goodie' and 'Care-Full'. On the basis of the analysis the paper brings out some areas of knowledge gaps and research needed to make public transport much more attractive and used by older people in the 21st century.

  15. Pregnancy in women aged 40 and older. (United States)

    O'Reilly-Green, C; Cohen, W R


    Counseling patients about pregnancy at advanced maternal age is a difficult process. This is true both because our knowledge of the attendant risks is incomplete and still evolving, and because of the difficulties of assigning risks and addressing counterbalancing benefits for individual patients. There are a number of social and personal considerations involved in a decision to become a parent after the age of 40. Generally, older parents tend to be more mature, to be in stable and healthy marriages, and to have more financial and family resources to assist with the process of child rearing. Parents in their fifth decade, however, may complain of having less energy to devote to young children or may be at a stage in their careers in which they have less time for family participation than when they were younger. Also, grandparents, who can play a critical role in early childhood development, often have become too old to participate in that role or have died. All of these issues must be considered by parents contemplating late childbearing. A great deal has been written, much of it positive, even enthusiastic, about the quality of pregnancy and childbirth among older women. Nevertheless, much of the literature is difficult to interpret because of problems in controlling for confounding variables. In addition, much of the focus on so-called older women has been on those older than 35 years. In fact, the great majority of the medical literature concerning late childbearing relates to women between the ages of 35 and 40. The data that directly concern women in their fifth decade suggest that risks that began to accelerate after the age of 35 become considerably greater and increase more rapidly after the age of 40. Obviously, couples must decide what risks they are willing to accept and how these potential risks might be countervailed by the presumed advantages of parenthood relatively late in the reproductive years. There is convincing evidence to show that fecundity

  16. Respiratory Syncytial Virus and Other Noninfluenza Respiratory Viruses in Older Adults. (United States)

    Kodama, Fumihiro; Nace, David A; Jump, Robin L P


    Respiratory viral infections may cause serious complications for older adults, including residents of long-term care facilities (LTCFs). Although influenza is the most common cause of viral respiratory infections among older adults, several other respiratory viruses also cause significant morbidity and mortality, most notably respiratory syncytial virus. Other noninfluenza respiratory viral pathogens include human metapneumovirus, parainfluenza virus, rhinovirus, coronavirus, and adenovirus. All of these may cause outbreaks among LTCF residents. Recently developed rapid diagnostic molecular tests may clarify the epidemiology of these viruses and have potential, through early identification, to limit the severity of outbreaks among older adults living in LTCFs.

  2. Health care for older persons in Switzerland: a country profile. (United States)

    Schoenenberger, Andreas W; Stuck, Andreas E


    Switzerland has the second-most-expensive healthcare system worldwide, with 11.5% of gross domestic product spent on health care in 2003. Switzerland has a healthcare system with universal insurance coverage and a social insurance system, ensuring an adequate financial situation for 96% of the 1.1 million older inhabitants. Key concerns related to the care of older persons are topics such as increasing healthcare costs, growing public awareness of patient autonomy, and challenges related to assisted suicide. In 2004, the Swiss Academy of Medical Sciences issued guidelines for the care of disabled older persons. Since 2000, geriatrics has been a board-certified discipline with a 3-year training program in addition to 5 years of training in internal or family medicine. There are approximately 125 certified geriatricians in Switzerland, working primarily in geriatric centers in urban areas. Switzerland has an excellent research environment, ranking second of all countries worldwide in life sciences research-but only 13th in aging research. This is in part due to a lack of specific training programs promoting research on aging and inadequate funding. In addition, there is a shortage of academic geriatricians in Switzerland, in part due to the fact that two of five Swiss universities had no academic geriatric departments in 2005. With more-adequate financial resources for academic geriatrics, Switzerland would have the opportunity to contribute more to aging research internationally and to improved care for older patients.

  3. Population Aging and Health Trajectories at Older Ages. (United States)

    Vogelsang, Eric M; Raymo, James M; Liang, Jersey; Kobayashi, Erika; Fukaya, Taro


    This study examines relationships between municipal age structure and two types of self-rated health: general (SRH) and comparison with similar-aged peers (C-SRH). Using a national sample of almost 5,000 Japanese older adults over two decades, we employ hierarchical growth curve models to estimate health trajectories. For municipal age structure, we consider both the relative prevalence of elderly adults in the local population and the pace of aging over time. Living in the oldest municipalities was generally associated with worse health, particularly between the ages of 70 and 80 years. For SRH, the speed of municipal population aging was also independently associated with worse health. For C-SRH, worse health in older areas was partially explained by less favorable economic conditions in those municipalities. Results also suggest that higher levels of employment and social integration among older adults living in the oldest municipalities operate in the opposite direction. That is, these attributes partially "protect" individuals from other factors that contribute to worse health. Relative differences in municipal age structure and the pace of population aging are largely unexplored and potentially important correlates of older adult health. This line of research is increasingly salient in a world with substantial and growing regional variation in population aging.

  4. Asymptomatic cervical spine fractures: Current guidelines can fail older patients. (United States)

    Healey, Christopher D; Spilman, Sarah K; King, Bradley D; Sherrill, Joseph E; Pelaez, Carlos A


    Older adults represent a growing proportion of trauma patients treated in the United States, and cervical spine (c-spine) fracture is an injury that is increasingly common in this population. Neck pain is a major component of current clinical clearance guidelines, but some older adults with c-spine fractures report no neck pain after injury. The objective of this study was to investigate the frequency at which c-spine fractures were unassociated with neck pain in an aging population. A retrospective review was performed for patients 55 years or older with a c-spine fracture during a 4-year study period. All patients had a Glasgow Coma Scale score of 15 and were considered asymptomatic if they did not complain of neck pain on initial presentation, denied tenderness to palpation of the c-spine on examination, and were without neurologic deficit. Differences between groups were assessed with Kruskal-Wallis and χ tests. Of 173 patients with c-spine fractures, 36 (21%) were asymptomatic and reported no neck pain on presentation or on examination. The group without neck pain had higher median injury severity scores (15 vs 10; p guidelines, denial of pain may lead to missed injury. We recommend liberal c-spine imaging for older trauma patients with significant mechanism of trauma. Therapeutic study, level III.

  6. Formaldehyde removal by common indoor plant species and various growing media (United States)

    Aydogan, Ahu; Montoya, Lupita D.


    Three porous materials (growstone, expanded clay and activated carbon) were evaluated as hydroponic growing media and for their individual ability to remove the indoor volatile organic compound formaldehyde under three conditions: growing medium alone, dry medium in a pot, and wet medium in a pot. The total percent-reduction of formaldehyde by each growing media was evaluated over a 10-h period. In all cases, activated carbon achieved the highest removal under the three conditions studied with average percent reductions measured at about 98%. Four common interior plants: Hedera helix (English ivy), Chrysanthemum morifolium (pot mum), Dieffenbachia compacta (dump cane) and Epipremnum aureum (golden pathos) growing in growstone were then tested for their ability to remove formaldehyde. The removal capacity of the aerial plant parts (AP), the root zone (RZ) and the entire plant (EP) growing in growstone were determined by exposing the relevant parts to gaseous formaldehyde (˜2000 μg m -3) in a closed chamber over a 24-h period. The removal efficiency between species and plant parts were compared by determining the time interval required to decrease about 2/3 of the total formaldehyde concentration reduction, T 2/3. The T 2/3 measured were 23, 30, 34 and 56 min for EP of C. morifolium, E. aureum, D. compacta and H. helix, respectively. The formaldehyde removal by the root zone was found to be more rapid than the removal by the aerial plant parts.

Nurses who are educated and comfortable about sexual orientation issues can provide a safe environment for older lesbian patients.

  9. Growing skull fracture stages and treatment strategy. (United States)

    Liu, Xue-Song; You, Chao; Lu, Ma; Liu, Jia-Gang


    A growing skull fracture (GSF) is a rare but significant late complication of skull fractures, usually occurring during infancy and early childhood. Delayed diagnosis and improper treatment could exacerbate this disease. The aim of this study was to introduce a new hypothesis about, describe the stages of, and discuss the treatment strategy for GSF. The authors performed a retrospective review of 27 patients with GSF, who were grouped according to 3 different GSF stages. Over a period of 20 years, 27 patients with GSF (16 males and 11 females) were treated in the authors' department. The mean follow-up period was 26.5 months. Six patients were in the prephase of GSF (Stage 1), 10 patients in the early phase (Stage 2), and 11 in the late phase (Stage 3). All patients underwent duraplasty. All 6 patients at Stage 1 and 5 patients at Stage 2 underwent craniotomy without cranioplasty. Five patients at Stage 2 and all of the patients at Stage 3 underwent cranioplasty with autologous bone and alloplastic materials, respectively. Among all patients, 5 underwent ventriculoperitoneal shunt placement. Symptoms in all patients at Stages 1 and 2 were alleviated or disappeared, and the cranial bones developed without deformity during follow-up. Among patients with Stage 3 GSF, no obvious improvement in neurological deficits was observed. Three patients underwent additional operations because of cranial deformation or infection. The authors identify the stages of GSF according to a new hypothesis. They conclude that accurately diagnosing and treating GSF during Stages 1 and 2 leads to a better prognosis.

  10. [Lung cancer and COPD - growing clinical problem]. (United States)

    Tyl, Michal; Domagała-Kulawik, Joanna


    A spread of the addiction of tobacco smoking is valued on near 1 billion of people in the world, that involves growing number of morbidity and mortality by the reason of smoke related diseases. Lung cancer and chronic obstructive pulmonary disease (COPD) are the most serious and incurable diseases which are leading to a permanent disability as well as to premature death. There are factors that naturally increase the vulnerability of an individual on the coincidence of above disorders, such as pathophysiological conditions, systemic inflammation, bronchitis, emphysema, respiratory obstructive disease and precise genetic predispositions for COPD and lung cancer. The harmful substances of the tobacco smoke are the causes of the development of diseases outside the group of respiratory disorders which affects the greater scope of comorbidity among this patient group in comparison to the normal population. The similarity of the clinical picture of lung cancer and COPD may cause numerous problems for a proper and prompt diagnosis and the implementation of the appropriate treatment. On the other hand, it is evident that the patients with COPD are carefully examined and often diagnosed with cancer while those who already suffer from cancer and undertake additional function testing are in 40-50% diagnosed with COPD. The coexistance of these two diseases influences the therapeutic procedure: COPD limits the possibilities of a radical lung cancer treatment which is determined by the general health condition and the respiratory system insufficiency as far as COPD patients are concerned. The knowledge of common pathogenesis both of cancer and COPD and the mutual relations between them shall positively affect the diagnostic and therapeutic process in the high-risk patient groups.

  11. The experience of nursing students visiting older adults living in rural communities. (United States)

    Walton, Joni; Blossom, Heidi


    The expanding population of older adults living in rural communities presents a rich opportunity for new clinical experiences for nursing students. The purpose of this research study was to explore the experiences of nursing students working with older adults in rural communities, the experiences of older adults, and the development of relationships. The sample included 96 nursing students and 16 older adults. Using the phenomenological method, we solicited comprehensive descriptions through open-ended questions. The following themes describe the experience of nursing students and the older adults they visited in their homes: (a) Welcoming Presence, (b) Developing a Trusting Relationship, (c) Spending Time Together, (d) Sharing and Listening to Stories, (e) Learning about Growing Old, and (f) Growing Nursing Students. Students believed that this experience was a vital component of their nursing education and it taught them how to develop a therapeutic relationship, learn how to listen, and how to be comfortable with themselves in the role of the student nurse. Students felt that the home setting was a safe environment to learn how to listen, carry out assessments, and receive feedback from older adults. This clinical experience can be easily implemented in a nursing curriculum to better prepare nurses for the challenges of the future. Copyright © 2013 Elsevier Inc. All rights reserved.

  12. Satellite communications - The ground segment grows (United States)

    Bulloch, C.; Rubin, P. W.


    The types of satellite telecommunication services and the markets for associated earth stations, i.e., antennas, are outlined. No fine line exists between fixed-service, mobile service and broadcast categories for satellite-ground transmissions. All transmissions are basically broadcast, can be received by anyone with appropriate equipment, and can originate at one point and be received at multiple points. Private data transmission services, delivering at a rate of 1.48 Mbps, are opening foreign markets once dominated by government telephone services, which were only capable of 64 kbps rates. Ku-band 14/11 GHz links are used increasingly to avoid saturation problems. DBS is still in its infancy while its main competition, satellite-cable distribution points, is an established system. Mobile services will increase rapidly with operational status for small, nondirectional antennas. A Japanese manufacturer currently supplies 35 percent of the world nonmilitary antenna demand, about 3000 to date. The figure will increase too, loosely, 10,000-20,000 by the year 2000.

  13. A growing danger: the risks posed by marihuana grow-ops

    Energy Technology Data Exchange (ETDEWEB)

    Bradley, F. [Canadian Electricity Association (Canada)


    The proliferation of sophisticated illegal indoor multi-plant marihuana cultivation operations is discussed, focusing primarily on public health and safety issues. Public health issues arise from the high level of molds and pollens caused by high humidity, which can cause asthma, respiratory conditions and allergies, particularly among children, and the likelihood of deadly levels of carbon monoxide build-up resulting from faulty rerouting of the residence's ventilation system. Safety issues discussed are: fires and electrocutions associated with the use of electrical diversions or bipasses to circumvent utility meters, the chemical and electrical hazards involved in investigating and dismantling growing operations, the significant dangers to utility crews who must repair illegal electrical bypasses, injuries by the booby-traps planted to protect the operation from other criminals or law enforcement agents, and the physical danger from the violence, including homicide and assaults, carried out by operators to exert control over production and distribution. Although in general, there is a relaxed attitude towards marihuana use in Canada. there is growing evidence of increasing public concern over large-scale growing operations. Nevertheless, to date operators of grow-ops have been dealt with lightly by the justice system. For example, in British Columbia 11,733 cases have come to the attention of police during the 1997 to 2000 period. Of these about half were dealt with informally (i.e. 'no case' seizures) and 2,255 cases led to at least one offender being convicted. The majority of convictions did not result in custodial dispositions. Only 18 per cent of the cases resulted in prison sentences, the average term being only 4.5 months.

  14. Excessive Body Weight in Older Adults: Concerns and Recommendations (United States)

    Porter Starr, Kathryn N.; Bales, Connie W.


    Synopsis Despite its growing pervasiveness, the health challenges prompted by obesity in the older adult population are poorly recognized and under-studied. A defined treatment for geriatric obesity is difficult to establish, as it must take into account biological heterogeneity, age-related co-morbidities, and functional limitations (sarcopenia/dynapenia). This restrospective article highlights our current understanding of the optimal body mass index (BMI) in later life, addressing appropriate recommendations based on BMI category, age, and health history. As the findings of randomized control trials of weight loss/maintenance interventions continue to accumulate, we are moving closer to evidence-based and appropriately individualized recommendations for body weight management in older adults.

    The body of evidence on older adults' sexual health is beginning to grow. However, it remains an under-researched area particularly within the social sciences. This viewpoint outlines four considerations for those who carry out social science research in this area: 1. defining the age category "older adults"; 2. being clear about the types of sex under research; 3. capturing a range of diverse voices; and 4. considering the use of qualitative research methods to explore the topic in depth. These suggestions are aimed at helping researchers to avoid some of the pitfalls of research in this area, as well as improving the evidence base in order to advance recognition of the issues and drive change in service provision.

  16. Family Assistance for Older Adults in Puerto Rico

    Directory of Open Access Journals (Sweden)

    Paul-Jesús Fericelli


    Full Text Available Global aging is a growing issue in most countries, including Puerto Rico. The well being of the older adult population depends mainly on a collaborative government initiative that uses both public assistance and the engagement of family members. Puerto Rican policymakers are searching for alternatives to care for the expanding elderly population as well as to protect the country’s economy, avoid the financial cliff, and reduce the high cost of public assistance. The purpose of this article is to analyze The Act for the Improvement of the Family Assistance and for the Support of the Elderly, Act No. 193 of 2002, under the criteria-based model (Gallagher & Haskins, 1984 with a value-critical appraisal (Chambers & Wedel, 2009. I suggest Act No. 193 of 2002 as a model for policymakers who are seeking ways to improve assistance for older adults, by promoting the following values: fairness, familism, fraternity, and accountability.

  19. Rapidly variable relatvistic absorption (United States)

    Parker, M.; Pinto, C.; Fabian, A.; Lohfink, A.; Buisson, D.; Alston, W.; Jiang, J.


    I will present results from the 1.5Ms XMM-Newton observing campaign on the most X-ray variable AGN, IRAS 13224-3809. We find a series of nine absorption lines with a velocity of 0.24c from an ultra-fast outflow. For the first time, we are able to see extremely rapid variability of the UFO features, and can link this to the X-ray variability from the inner accretion disk. We find a clear flux dependence of the outflow features, suggesting that the wind is ionized by increasing X-ray emission.

  20. Rapid prototype and test

    Energy Technology Data Exchange (ETDEWEB)

    Gregory, D.L.; Hansche, B.D.


    In order to support advanced manufacturing, Sandia has acquired the capability to produce plastic prototypes using stereolithography. Currently, these prototypes are used mainly to verify part geometry and ``fit and form`` checks. This project investigates methods for rapidly testing these plastic prototypes, and inferring from prototype test data actual metal part performance and behavior. Performances examined include static load/stress response, and structural dynamic (modal) and vibration behavior. The integration of advanced non-contacting measurement techniques including scanning laser velocimetry, laser holography, and thermoelasticity into testing of these prototypes is described. Photoelastic properties of the epoxy prototypes to reveal full field stress/strain fields are also explored.

  2. On carbon footprints and growing energy use

    Energy Technology Data Exchange (ETDEWEB)

    Oldenburg, C.M.


    Could fractional reductions in the carbon footprint of a growing organization lead to a corresponding real reduction in atmospheric CO{sub 2} emissions in the next ten years? Curtis M. Oldenburg, head of the Geologic Carbon Sequestration Program of LBNL’s Earth Sciences Division, considers his own organization's carbon footprint and answers this critical question? In addressing the problem of energy-related greenhouse gas (GHG) emissions and climate change, it is essential that we understand which activities are producing GHGs and the scale of emission for each activity, so that reduction efforts can be efficiently targeted. The GHG emissions to the atmosphere of an individual or group are referred to as the ‘carbon footprint’. This terminology is entirely appropriate, because 85% of the global marketed energy supply comes from carbon-rich fossil fuel sources whose combustion produces CO{sub 2}, the main GHG causing global climate change. Furthermore, the direct relation between CO2 emissions and fossil fuels as they are used today makes energy consumption a useful proxy for carbon footprint. It would seem to be a simple matter to reduce energy consumption across the board, both individually and collectively, to help reduce our carbon footprints and therefore solve the energyclimate crisis. But just how much can we reduce carbon footprints when broader forces, such as growth in energy use, cause the total footprint to simultaneously expand? In this feature, I present a calculation of the carbon footprint of the Earth Sciences Division (ESD), the division in which I work at Lawrence Berkeley National Laboratory (LBNL), and discuss the potential for reducing this carbon footprint. It will be apparent that in terms of potential future carbon footprint reductions under projections of expected growth, ESD may be thought of as a microcosm of the situation of the world as a whole, in which alternatives to the business-as-usual use of fossil fuels are needed if

  3. Severe sepsis in older adults. (United States)

    Umberger, Reba; Callen, Bonnie; Brown, Mary Lynn


    Severe sepsis may be underrecognized in older adults. Therefore, the purpose of this article is to review special considerations related to early detection of severe sepsis in older adults. Normal organ changes attributed to aging may delay early detection of sepsis at the time when interventions have the greatest potential to improve patient outcomes. Systems are reviewed for changes. For example, the cardiovascular system may have a limited or absent compensatory response to inflammation after an infectious insult, and the febrile response and recruitment of white blood cells may be blunted because of immunosenescence in aging. Three of the 4 hallmark responses (temperature, heart rate, and white blood cell count) to systemic inflammation may be diminished in older adults as compared with younger adults. It is important to consider that older adults may not always manifest the typical systemic inflammatory response syndrome. Atypical signs such as confusion, decreased appetite, and unsteady gait may occur before sepsis related organ failure. Systemic inflammatory response syndrome criteria and a comparison of organ failure criteria were reviewed. Mortality rates in sepsis and severe sepsis remain high and are often complicated by multiple organ failures. As the numbers of older adults increase, early identification and prompt treatment is crucial in improving patient outcomes.

  4. Fecal incontinence in older patients. (United States)

    Akhtar, Abbasi J; Padda, Manmeet


    Fecal incontinence (FI), the involuntary passage of fecal material through the anus, is a common medical problem in older people, especially in frail older nursing home residents. FI is often associated with urinary incontinence. Severe constipation leading to fecal impaction, laxative abuse, diarrhea, cognitive impairment, senescence, and neuromuscular disorders including autonomic neuropathy, are among the leading causes of FI in older patients. FI affects patients' physical and psychological well-being, and is responsible for considerable morbidity and mortality in older patients. This results in significant healthcare costs. Comprehensive management of this disorder requires a systematic approach including thorough history, physical examination, and step-wise evaluation. This review in contrast to others published in last decade, focuses on management of FI in frail older nursing home patients, who require an individualized approach, which should be minimally invasive and cost-effective. In many cases of FI, treatment of the underlying condition; adequate control of diarrhea, constipation, or fecal impaction; adjustment of medications; and proper feeding may control or reduce FI. Advanced tests are often not necessary in this population.

  5. Rapid mineralocorticoid receptor trafficking. (United States)

    Gekle, M; Bretschneider, M; Meinel, S; Ruhs, S; Grossmann, C


    The mineralocorticoid receptor (MR) is a ligand-dependent transcription factor that physiologically regulates water-electrolyte homeostasis and controls blood pressure. The MR can also elicit inflammatory and remodeling processes in the cardiovascular system and the kidneys, which require the presence of additional pathological factors like for example nitrosative stress. However, the underlying molecular mechanism(s) for pathophysiological MR effects remain(s) elusive. The inactive MR is located in the cytosol associated with chaperone molecules including HSP90. After ligand binding, the MR monomer rapidly translocates into the nucleus while still being associated to HSP90 and after dissociation from HSP90 binds to hormone-response-elements called glucocorticoid response elements (GREs) as a dimer. There are indications that rapid MR trafficking is modulated in the presence of high salt, oxidative or nitrosative stress, hypothetically by induction or posttranslational modifications. Additionally, glucocorticoids and the enzyme 11beta hydroxysteroid dehydrogenase may also influence MR activation. Because MR trafficking and its modulation by micro-milieu factors influence MR cellular localization, it is not only relevant for genomic but also for nongenomic MR effects.

  6. Rapid response manufacturing (RRM)

    Energy Technology Data Exchange (ETDEWEB)

    Cain, W.D. [Lockheed Martin Energy Systems, Inc., Oak Ridge, TN (United States); Waddell, W.L. [National Centers for Manufacturing Sciences, Ann Arbor, MI (United States)


    US industry is fighting to maintain its competitive edge in the global market place. Today markets fluctuate rapidly. Companies, to survive, have to be able to respond with quick-to-market, improved, high quality, cost efficient products. The way products are developed and brought to market can be improved and made more efficient through the proper incorporation of emerging technologies. The RRM project was established to leverage the expertise and resources of US private industries and federal agencies to develop, integrate, and deploy new technologies that meet critical needs for effective product realization. The RRM program addressed a needed change in the US Manufacturing infrastructure that will ensure US competitiveness in world market typified by mass customization. This project provided the effort needed to define, develop and establish a customizable infrastructure for rapid response product development design and manufacturing. A major project achievement was the development of a broad-based framework for automating and integrating the product and process design and manufacturing activities involved with machined parts. This was accomplished by coordinating and extending the application of feature-based product modeling, knowledge-based systems, integrated data management, and direct manufacturing technologies in a cooperative integrated computing environment. Key technological advancements include a product model that integrates product and process data in a consistent, minimally redundant manner, an advanced computer-aided engineering environment, knowledge-based software aids for design and process planning, and new production technologies to make products directly from design application software.

  7. Assessment of personal care and medical robots from older adults' perspective. (United States)

    Goher, K M; Mansouri, N; Fadlallah, S O


    Demographic reports indicate that population of older adults is growing significantly over the world and in particular in developed nations. Consequently, there are a noticeable number of demands for certain services such as health-care systems and assistive medical robots and devices. In today's world, different types of robots play substantial roles specifically in medical sector to facilitate human life, especially older adults. Assistive medical robots and devices are created in various designs to fulfill specific needs of older adults. Though medical robots are utilized widely by senior citizens, it is dramatic to find out into what extent assistive robots satisfy their needs and expectations. This paper reviews various assessments of assistive medical robots from older adults' perspectives with the purpose of identifying senior citizen's needs, expectations, and preferences. On the other hand, these kinds of assessments inform robot designers, developers, and programmers to come up with robots fulfilling elderly's needs while improving their life quality.

  8. Another health insurance gap: gaining and losing coverage among natives and immigrants at older ages. (United States)

    Reyes, Adriana M; Hardy, Melissa


    As the immigrant population grows older and larger, limitations on access to health insurance may create a new subgroup of people who remain outside or on the margin of coverage. Using the Survey of Income and Program Participation (SIPP) data from the 2004 and 2008 panels, we address the health insurance gap between foreign-born and native-born adults among those aged 50-64 and the 65 and older, two sub-populations that have received relatively little attention in past research. We argue that current practices leave a significant minority of older foreign-born residents inconsistently covered or without any insurance. We find that health insurance coverage for older immigrants is both less likely and more episodic even when compositional differences in SES and assimilation are controlled.

    Nielsen, Tove Lise; Andersen, Niels Trolle; Petersen, Kirsten Schultz


    BACKGROUND: There is growing interest in enabling older adults' occupational performance. We tested whether 11 weeks of intensive client-centred occupational therapy (ICC-OT) was superior to usual practice in improving the occupational performance of home-dwelling older adults. METHODS: An assessor...... either a maximum 22 sessions of occupation-based ICC-OT (N = 59) or to receive usual practice with a maximum three sessions of occupational therapy (N = 60). The primary outcome was self-rated occupational performance assessed with the Canadian Occupational Performance Measure (COPM). RESULTS......% confidence interval 0.50 to 2.02), t-test: p = 0.001. CONCLUSIONS: ICC-OT improved older adults' occupational performance more effectively than usual practice. This result may benefit older adults and support programmatic changes....

  10. Oropharyngeal dysphagia in older persons – from pathophysiology to adequate intervention

    DEFF Research Database (Denmark)

    Wirth, Rainer; Beck, Anne Marie; Dziewas, Rainer


    Oropharyngeal dysphagia (OD) is a highly prevalent and growing condition in the older population. Although OD may cause very severe complications, it is often not detected, explored, and treated. Older patients are frequently unaware of their swallowing dysfunction which is one of the reasons why...... the consequences of OD, ie, aspiration, dehydration, and malnutrition, are regularly not attributed to dysphagia. Older patients are particularly vulnerable to dysphagia because multiple age-related changes increase the risk of dysphagia. Physicians in charge of older patients should be aware that malnutrition......, dehydration, and pneumonia are frequently caused by (unrecognized) dysphagia. The diagnosis is particularly difficult in the case of silent aspiration. In addition to numerous screening tools, videofluoroscopy was the traditional gold standard of diagnosing OD. Recently, the fiberoptic endoscopic evaluation...

    Objectives: The aim of the current article was to provide an overview of literature on sexual function and sexual difficulties in older adults. Method: The authors conducted a narrative review of papers published in English between January 2005 and July 2015 based on an extensive search in Psyc......INFO. Results: The review showed that although common biological changes may adversely affect sexual function in old age, sexual experience seems to also be affected by psychological and interpersonal factors. Conclusions: Greater life expectancy and better medical care will result in older individuals...... with chronic diseases living longer. The need for help to cope with changes in sexual health is likely to increase in older adults, as sexuality may be negatively affected through several pathways....

  12. Health Literacy and Older Adults (United States)

    Chesser, Amy K.; Keene Woods, Nikki; Smothers, Kyle; Rogers, Nicole


    Objective: The objective of this review was to assess published literature relating to health literacy and older adults. Method: The current review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta Analyses. Results: Eight articles met inclusion criteria. All studies were conducted in urban settings in the United States. Study sample size ranged from 33 to 3,000 participants. Two studies evaluated health-related outcomes and reported significant associations between low health literacy and poorer health outcomes. Two other studies investigated the impact of health literacy on medication management, reporting mixed findings. Discussion: The findings of this review highlight the importance of working to improve health care strategies for older adults with low health literacy and highlight the need for a standardized and validated clinical health literacy screening tool for older adults.

  13. Intersection assistance: a safe solution for older drivers? (United States)

    Dotzauer, Mandy; Caljouw, Simone R; de Waard, Dick; Brouwer, Wiebo H


    Within the next few decades, the number of older drivers operating a vehicle will increase rapidly (Eurostat, 2011). As age increases so does physical vulnerability, age-related impairments, and the risk of being involved in a fatal crashes. Older drivers experience problems in driving situations that require divided attention and decision making under time pressure as reflected by their overrepresentation in at-fault crashes on intersections. Advanced Driver Assistance Systems (ADAS) especially designed to support older drivers crossing intersections might counteract these difficulties. In a longer-term driving simulator study, the effects of an intersection assistant on driving were evaluated. 18 older drivers (M=71.44 years) returned repeatedly completing a ride either with or without a support system in a driving simulator. In order to test the intersection assistance, eight intersections were depicted for further analyses. Results show that ADAS affects driving. Equipped with ADAS, drivers allocated more attention to the road center rather than the left and right, crossed intersections in shorter time, engaged in higher speeds, and crossed more often with a critical time-to-collision (TTC) value. The implications of results are discussed in terms of behavioral adaptation and safety. Copyright © 2013 Elsevier Ltd. All rights reserved.

  14. Sociodemographic risk factors and correlates of dementia in older Malaysians. (United States)

    Hamid, Tengku Aizan; Krishnaswamy, Saroja; Abdullah, Siti Suhailah; Momtaz, Yadollah Abolfathi


    The rapid expansion of the aged population in Malaysia is expected to greatly increase the number of persons with dementia in the country. However, data on dementia prevalence at the national level is lacking, and little is known about the sociodemographic risk factors and correlates of dementia. This paper describes a nationwide study of dementia prevalence and its sociodemographic risk factors and health correlates among older Malaysians. In the nationwide study, the Mental Health and Quality of Life of Older Malaysians, AGECAT-GMS was used to diagnose dementia in a nationally representative sample of 2,980 persons aged 60 and above. The prevalence rate of dementia was 14.3%. Higher dementia prevalences were found in oldest age (26.3%), women (19.7%), no formal education (24.1%), Bumiputeras (32.2%), unmarried (19.4%), unemployed (31.3%) and very poor on self-rated health (33.3%). Multivariate logistic regression analyses showed that older age, female gender, no formal education, ethnicity and very poor self-rated health were independent risk factors and correlates of dementia. Relatively higher prevalence rates of dementia in older Malaysians were accounted for by greater proportions without education, Malay and Bumiputera ethnicity, and other unknown factors which should be further investigated.

  15. Dietary screening tool identifies nutritional risk in older adults123 (United States)

    Miller, Paige E; Mitchell, Diane C; Hartman, Terryl J; Lawrence, Frank R; Sempos, Christopher T; Smiciklas-Wright, Helen


    Background: No rapid methods exist for screening overall dietary intakes in older adults. Objective: The purpose of this study was to develop and evaluate a scoring system for a diet screening tool to identify nutritional risk in community-dwelling older adults. Design: This cross-sectional study in older adults (n = 204) who reside in rural areas examined nutrition status by using an in-person interview, biochemical measures, and four 24-h recalls that included the use of dietary supplements. Results: The dietary screening tool was able to characterize 3 levels of nutritional risk: at risk, possible risk, and not at risk. Individuals classified as at nutritional risk had significantly lower indicators of diet quality (Healthy Eating Index and Mean Adequacy Ratio) and intakes of protein, most micronutrients, dietary fiber, fruit, and vegetables. The at-risk group had higher intakes of fats and oils and refined grains. The at-risk group also had the lowest serum vitamin B-12, folate, β-cryptoxanthin, lutein, and zeaxanthin concentrations. The not-at-nutritional-risk group had significantly higher lycopene and β-carotene and lower homocysteine and methylmalonic acid concentrations. Conclusion: The dietary screening tool is a simple and practical tool that can help to detect nutritional risk in older adults. PMID:19458013

  16. Reasons for the Fast Growing Seawater Desalination Capacity in Algeria

    KAUST Repository

    Drouiche, Nadjib


    Seawater/brackish water desalination has been widely adopted by the Algerian Government in the last few years to supply potable water to municipality for various purposes mainly for domestic and industrial uses especially in areas where demand is high due to shortage of fresh water resources, rapid population growth and development of industry and tourism. Ten years ago, desalination was confined to the industrial use only especially in oil and gas industry as the country was relying on rain water and other available sources to supply fresh water to municipalities. Due to chronic drought conditions, the Ministry of Water Resources reviewed the national water strategy and a strong option for desalination was adopted where an ambitious program was thus put into action. Sixteen mega-plants, with capacities ranging from 100,000 to 500,000 m3 per day, primarily based on Reverse Osmosis technology, were launched in the last few years making the Algerian desalination program one of the world\\'s fastest growing markets. Five desalination plants, including the Africa\\'s largest seawater reverse osmosis project with a total capacity of 200,000 m3 per day, are already in operation and the remaining projects are either under construction or in commissioning. An integrated water resources management was also adopted as additional option to cuter the increasing water demand as there is also a great potential for water reuse and conventional water treatment. An additional benefit of this would be reducing the volume of treated wastewater disposed into the environment. © 2011 Springer Science+Business Media B.V.

  17. Homicide perpetrated by older people. (United States)

    Overshott, Ross; Rodway, Cathryn; Roscoe, Alison; Flynn, Sandra; Hunt, Isabelle M; Swinson, Nicola; Appleby, Louis; Shaw, Jenny


    This study aims to describe the circumstances in which older people commit homicide, the form of assessment they undergo and to examine the proportion of those who suffer from mental illness. The study was carried out as part of the England and Wales National Confidential Inquiry into Suicide and Homicide by People with Mental Illness based on a five-year sample. The Inquiry was notified of the names of those over the age of 60 years convicted of homicide and also the details of the offence, sentencing and outcome in court by the Home Office. The Inquiry collected clinical data of those known to have had contact with mental health services from the responsible service and also retrieved psychiatric reports of those convicted. Homicide incidents perpetrated by older people typically involve a man killing his partner in an impulsive manner. The most common method was by using a sharp instrument (34%), followed by the use of a blunt instrument (26%). The use of firearms was rare (11%). Perpetrators aged 65 years and older were significantly more likely to kill a current or former spouse/partner and less likely to kill an acquaintance. Forty-four per cent of perpetrators over 65 years old suffered from depression at the time of the offence, whereas rates of schizophrenia and alcohol dependence were low. The information used in the study was extracted from a unique national database of homicide perpetrators. The characteristics and the circumstances of homicides perpetrated by older people are different to other age groups. An older-people homicide may be preventable if depression is identified early in older people. Copyright © 2012 John Wiley & Sons, Ltd.

  20. Vaccinations for the Older Adult. (United States)

    Gnanasekaran, Gowrishankar; Biedenbender, Rex; Davidson, Harley Edward; Gravenstein, Stefan


    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. Copyright © 2016 Elsevier Inc. All rights reserved.

  3. Predictors of suicide ideation among older adults with bipolar disorder.

    Directory of Open Access Journals (Sweden)

    Norm O'Rourke

    Full Text Available Bipolar disorder (BD carries the greatest risk of death by suicide of all psychiatric conditions as 25%-50% of those with BD will make one or more suicide attempt, and about 15% will intentionally end their lives. Among young adults with BD, substance misuse, medication non-adherence, age at onset, and comorbid psychiatric conditions each predict self-harm. It is currently unclear if these same factors or others predict suicide ideation among older adults with BD.We recruited a global sample of 220 older adults with BD over 19 days using socio-demographically targeted, social media advertising and online data collection (Mean = 58.50, SD = 5.42; range 50 to 81 years. Path analyses allowed us to identify direct and indirect predictors of suicide ideation among older adults with BD.Cognitive failures (perception, memory, and motor function, depressive symptoms, alcohol misuse, and dissatisfaction with life as direct predictors of suicide ideation; duration of BD symptoms and medication non-adherence emerged as indirect predictors. Of note, the significant impact of sleep on suicide ideation is indirect via depressive symptoms, cognitive failures, medication non-adherence and life dissatisfaction.As with young adults with BD, alcohol misuse and medication non-adherence emerged as significant predictors of suicide ideation. In addition, cognitive failures directly and indirectly predict suicide ideation in this sample of older adults with BD. Population aging and treatment efficacy are leading to ever growing numbers of older adults with BD. Both direct and indirect predictors of suicide ideation need to be considered in future BD research and treatment planning.

  4. Rapid chemical separations

    Trautmann, N


    A survey is given on the progress of fast chemical separation procedures during the last few years. Fast, discontinuous separation techniques are illustrated by a procedure for niobium. The use of such techniques for the chemical characterization of the heaviest known elements is described. Other rapid separation methods from aqueous solutions are summarized. The application of the high speed liquid chromatography to the separation of chemically similar elements is outlined. The use of the gas jet recoil transport method for nuclear reaction products and its combination with a continuous solvent extraction technique and with a thermochromatographic separation is presented. Different separation methods in the gas phase are briefly discussed and the attachment of a thermochromatographic technique to an on-line mass separator is shown. (45 refs).

  5. Attention and the acquisition of new knowledge: their effects on older adults' associative memory deficit. (United States)

    Cooper, Crystal M; Odegard, Timothy N


    Older adults experience a selective associative memory deficit by demonstrating intact item memory relative to impaired associative memory when compared with younger adults. Age-related deficits in associative memory have been suggested to arise from declines in attentional resources, and the role of attention during encoding and retrieval in associative memory for words and their spatial locations was investigated in the current experiment. Additionally, the tendency of younger and older adults to use knowledge acquired during encoding to improve their associative memory judgments through a strategic associative memory process was also investigated. Younger and older adults studied a list of words with each word belonging to one of four categories, which followed one of four mathematical probability structures for their presentation. Older adults exhibited intact item memory and impaired associative memory relative to full attention younger adults. In addition, both older and younger adults demonstrated an ability to engage in strategic associative memory, by learning and later using the probability structure introduced at study to guide their associative memory judgments. In contrast, dividing the attention of younger adults during encoding impaired item memory, associative memory and strategic associative memory, whereas dividing attention at retrieval did not result in similar deficits. These data add to a growing body of literature demonstrating older adults to exhibit a selective associative memory deficit that is not simulated by dividing the attention of younger adults at encoding or retrieval. Furthermore, younger and older adults maintain the ability to use new knowledge to guide their associative judgments.

  6. Glycemic targets and medication limitations for type 2 diabetes mellitus in the older adult. (United States)

    Thompson, Angela M; Linnebur, Sunny A; Vande Griend, Joseph P; Saseen, Joseph J


    To review the optimal management of type 2 diabetes mellitus (T2DM) in the older adult. A PubMed search was completed to identify publications in the English language from 1947 to 2013 using combinations of the search terms: geriatrics, aged, diabetes mellitus, and type 2 diabetes mellitus. References of articles were also reviewed for inclusion if not identified in the PubMed search. Original studies, clinical reviews, and guidelines were identified and evaluated for clinical relevance. Although the number of older adults with T2DM is growing, evidence for the treatment of T2DM in this population is lacking. Barriers such as polypharmacy, comorbid conditions, economic limitations, cognitive impairment, and increased risk of hypoglycemia may limit optimal glycemic control in older adults. Several organizations provide recommendations for glycemic targets and recommend using standard glycemic goals in most healthy older adults. However, less stringent goals are necessary in certain older populations such as those patients with limited life expectancy and severe hypoglycemia. In general, glycemic goals should be individualized in older patients. Age-related pharmacokinetic and pharmacodynamic changes, comorbid conditions, adverse drug reactions, ease of medication administration, and cost of medications necessitate the need to individualize pharmacologic therapy. Glycemic targets and medication use for T2DM should be individualized in older adults.

  7. Tobacco-control policies in tobacco-growing states: where tobacco was king. (United States)

    Fallin, Amanda; Glantz, Stanton A


    POLICY POINTS: The tobacco companies prioritized blocking tobacco-control policies in tobacco-growing states and partnered with tobacco farmers to oppose tobacco-control policies. The 1998 Master Settlement Agreement, which settled state litigation against the cigarette companies, the 2004 tobacco-quota buyout, and the companies' increasing use of foreign tobacco led to a rift between the companies and tobacco farmers. In 2003, the first comprehensive smoke-free local law was passed in a major tobacco-growing state, and there has been steady progress in the region since then. Health advocates should educate the public and policymakers on the changing reality in tobacco-growing states, notably the major reduction in the volume of tobacco produced. The 5 major tobacco-growing states (Kentucky, North Carolina, South Carolina, Tennessee, and Virginia) are disproportionately affected by the tobacco epidemic, with higher rates of smoking and smoking-induced disease. These states also have fewer smoke-free laws and lower tobacco taxes, 2 evidence-based policies that reduce tobacco use. Historically, the tobacco farmers and hospitality associations allied with the tobacco companies to oppose these policies. This research is based on 5 detailed case studies of these states, which included key informant interviews, previously secret tobacco industry documents (available at, and media articles. This was supplemented with additional tobacco document and media searches specifically for this article. The tobacco companies were particularly concerned about blocking tobacco-control policies in the tobacco-growing states by promoting a pro-tobacco culture, beginning in the late 1960s. Nevertheless, since 2003, there has been rapid progress in the tobacco-growing states' passage of smoke-free laws. This progress came after the alliance between the tobacco companies and the tobacco farmers fractured and hospitality organizations stopped opposing smoke

  8. Challenges of the growing African cement market – environmental issues, regulative framework, and quality infrastructure requirements

    Directory of Open Access Journals (Sweden)

    Schmidt Wolfram


    Full Text Available The African cement, concrete and construction business is growing at rapid pace. The cement sales are expected to grow rapidly until 2050. The number of newly built cement plants increases dramatically and in addition more cements are being imported from outside the continent, e.g. from Turkey, Pakistan, Indonesia, and China, driven by overcapacities in the countries of origin. This causes a high number of potentials and challenges at the same time. Newly built cement plants can operate directly at best technological state of the art and thus incorporate more sustainable technologies as well as produce new and more sustainable products such as cements blended with sustainable supplementary cementitious materials such as calcined clays, and industrial or agricultural by products. At the same time the new variety of binding agent as well as the international imports, which are driven by price considerations, make the cement market prone to quality scatter. This puts pressure on the quality control regulations and institutions to ensure safety of construction, healthy application, and environmental safety for the population. The paper presents possible solutions to build up the rapidly increasing African cement production more sustainably than in the rest of the world as well as the related challenges and obstacles that need to be overcome. Based on experiences with a series of pan-African cement testing laboratory proficiency schemes conclusions are made on technical, regulative and political level.

  9. Predictors of functional disability with focus on activities of daily living: A community based follow-up study in older adults in India. (United States)

    Nagarkar, Aarti; Kashikar, Yashoda

    Disability in activities of daily living is a growing concern among older populations all over the world. India has one of the rapidly ageing populations and predicted burden of functional disability is higher for Indian older adults as compared to other ageing Asian countries. Total 1140 aged 60 years and over participated in a baseline study. 560 of them participated in the prospective cohort study conducted in the city of Pune, India. An interview and functional assessment using a questionnaire and Pune-FAAT tool was carried out in 2013-14. Binary logistic regression was used to obtain the factors that increased the odds of having ADL disability at follow-up. The mean age of the study population was 69.73±5.48years. Squatting, walking and climbing functions were affected significantly. Total 376 participants (67.1%) reported difficulties and/or disability in performing activities of daily living (ADL) at follow-up. Hospitalization (OR=3.6; 95% CI: 1.9-6.7), being female (OR=2.3; 95% CI: 1.5-3.5), presence of two or more chronic diseases (OR=1.7; 95% CI: 1.1-2.7), experience of memory loss (OR=1.9; 95% CI: 1.2-3.0) and feeling of loneliness (OR=2.3; 95% CI: 1.0-5.3) increased the odds of being in the "With disability" group at follow-up. Apart from this, self-rated health and self-reported depression were associated with limitations in ADL. Hospitalization and being female appeared to be the most significant risk factors for disability in urban older adults in India. Rehabilitation services after hospitalization, physical exercise, effective control on chronic illness, and social participation to reduce loneliness is recommended.

  10. Balance control in the elderly: do Masters athletes show more efficient balance responses than healthy older adults? (United States)

    Brauer, Sandra G; Neros, Christina; Woollacott, Marjorie


    Older adults can improve several components of their balance such as timed stance ability by participating in a short specific exercise program. However, it is not clear whether participation in more frequent and intense training can result in improved reactive balance performance in older adults. Optimal reactive responses are required to prevent falls. This study begins to evaluate this issue by comparing the reactive balance ability of elite older adults (Masters athletes) to that of healthy older adults. Kinetic and electromyography data were collected from elite older athletes and healthy older adults during backward linear underfoot perturbations at high and low speeds. Behavioral outcomes of postural recovery strategy, timing and levels of muscular activation, and time to stabilize the displaced center of pressure were measured and compared between groups. The elite older athletes were able to more frequently regain balance without stepping, stabilized their center of pressure faster than did healthy older adults and activated their tibialis anterior with a greater magnitude when perturbed at the higher speed. There were no differences between groups in these measures at the lower perturbation speed and no differences in onset latencies at either speed. Older athletes undertaking longterm high intensity training demonstrate better and more rapid stabilization of posture following perturbation than healthy older adults under challenging conditions. Further studies are advocated to determine the relative contribution of processes such as neuromotor adaptation, strength, motivation and arousal to this finding.

  11. eHealth Literacy: Patient Engagement in Identifying Strategies to Encourage Use of Patient Portals Among Older Adults. (United States)

    Price-Haywood, Eboni G; Harden-Barrios, Jewel; Ulep, Robin; Luo, Qingyang


    Innovations in chronic disease management are growing rapidly as advancements in technology broaden the scope of tools. Older adults are less likely to be willing or able to use patient portals or smartphone apps for health-related tasks. The authors conducted a cross-sectional survey of older adults (ages ≥50) with hypertension or diabetes to examine relationships between portal usage, interest in health-tracking tools, and eHealth literacy, and to solicit practical solutions to encourage technology adoption. Among 247 patients surveyed in a large integrated delivery health system between August 2015 and January 2016, eHealth literacy was positively associated with portal usage (OR [95% CI]: 1.3 [1.2-1.5]) and interest in health-tracking tools (1.2 [1.1-1.3]). Portal users compared to nonusers (N = 137 vs.110) had higher rates of interest in using websites/smartphone apps to track blood pressure (55% vs. 36%), weight (53% vs. 35%), exercise (53% vs. 32%), or medication (46% vs 33%, all P security, lack of personalization, and limited perceived value of using portals. Both groups noted the importance of computer literacy and technical support. Patient stakeholders recommended marketing initiatives that capture patient stories demonstrating real-life applications of what patients can do with digital technology, how to use it, and why it may be useful. Health systems also must screen for eHealth literacy, provide training, promote proxy users, and institute quality assurance that ensures patients' experiences will not vary across the system.

Method: A narrative literature search using the PsycINFO database was conducted. Results: Although women in general seem less satisfied...... with their bodies than men, particularly in sexual contexts, older women appear to be less vulnerable to body-related dissatisfaction than younger women. Despite the age-specific dynamics of sexual satisfaction and sexual well-being, which parallel age-related decrease in the frequency of sexual activity, research...... findings from different countries show that substantial proportions of aging men and women are satisfied with their sex life. There is some limited evidence that this proportion may be increasing across cohorts. Gender differences in factors that influence sexual satisfaction among older adults appear...
