Hearing Impairment and Tinnitus in the Elderly

The purpose of this study was to gather information on hearing impairment and related factors among elderly people. The HHIE-S questionnaire (Hearing Handicap Inventory for Elderly-Screening) and a single hearing question (”Do you feel you have a hearing loss”) were compared to audiometric hearing thresholds (N=164). HHIE-S was reliable for detecting moderate or worse hearing impairment. The single question was equally sensitive and more specific in identifying mild hearing impairment. The prevalence of hearing impairment was evaluated in four age cohorts (70, 75, 80 and 85 years, N=4067) in Turku, Finland. The HHIE-S cut-off score >8 as an indicator of at least mild hearing impairment yielded prevalence values of 37.7% - 54.1%, and a score >18 (moderate or more severe hearing impairment) was 21.1% - 38.9%. The single question test was positive in 25.5% - 46.2%. Hearing aid compliance and problems experienced by hearing aid users were recorded as informed by the participants in a mailed interview (N=249/4067). The hearing aids were used daily by 55.4%, and never by 10.7%. Use sank with advancing age. The disturbance caused by tinnitus among 583 subjects was compared to their level of alexithymia (TAS-20) and depressiveness (BDI). Depressiveness was weakly associated with annoying tinnitus, but not alexithymia. The prevalence of hearing impairment can be measured by enquiry. Hearing aid compliance should be improved by technical means and better counseling. The factors affecting the distress experienced by tinnitus patients need further study.

Oxidized LDL and physical fitness in healthy young men: associations with body composition, smoking, metabolic syndrome and androgen status

Background: In the past, oxidized low density lipoprotein (ox-LDL) has been associated with an unbeneficial lipid profile. This atherogenic lipid profile increases the risk of atherosclerotic cardiovascular diseases. Physical fitness has substantial effect on serum lipoprotein concentration as well as body composition and humoral responses, however interrelationships between ox-LDL and physical fitness have not been widely examined in a nationally representative sample. Aims: This thesis evaluates how cardiorespiratory and muscular fitness associate with ox-LDL lipids and how the other known risk factors of atherosclerosis might alter these associations. Subjects and Methods: The study cohort consisted of 846 healthy young males (mean age 25.1, SD 4.6) who were gathered by voluntary nationwide recruitment. Each participant conducted a series of physical fitness tests (cardiorespiratory and muscular fitness) and answered a detailed questionnaire that included lifestyle habits (i.e. smoking and leisuretime physical activity). Venous blood samples including ox-LDL and serum lipids were also collected. Results: Higher levels of ox-LDL were found in overweight and obese men, however, high cardiorespiratory fitness seemed to protect the overweight from high levels of ox-LDL. Young men who smoked and had poor cardiorespiratory or muscular fitness possessed a higher concentration of ox-LDL lipids when compared to comparable levels of cardiorespiratory or muscular fitness non-smoking young men. Metabolic syndrome was associated with increased levels of ox-LDL and high levels of ox-LDL combined with poor cardiorespiratory and abdominal muscle fitness seems to predict metabolic syndrome in young men. Also, participants with poor cardiorespiratory fitness and low levels of testosterone had higher levels of ox-LDL when compared to participants with high cardiorespiratory fitness / low testosterone as well as those with poor cardiorespiratory fitness / high testosterone. Conclusions: Good cardiorespiratory and muscular fitness protects young men from increased levels of ox-LDL lipids. This association was discovered in young men who were categorized as being overweight, smokers, metabolic syndrome or with low levels of testosterone. Being fit seems to prevent higher levels of ox-LDL, even in young healthy

Productivity and Services – Safety Telephone Services for the Elderly

Previous research on productivity is often associated with manufacturing or uses manufacturing definitions of productivity. Marketing research on services has not been satisfied with the manufacturing definitions. No universal definition for service productivity exists. The lack of a universal definition highlights the complexity entailed in the concept of productivity. The objective of this study was to investigate service productivity in situations, where traditional ways are in some cases even not possible or are not enough. In one definition of the productivity of service organisations there is the efficiency of the organisation on the input side and on the output side the customers’ perceived quality or value-in-use. To learn about value-in-use, many methods have been developed. A common practice is to make customer opinion surveys in the form of customer questionnaires and interviews. However, customers cannot always be asked directly, for example, because of impaired cognitive abilities. Such cases include the elderly and children. Furthermore, customer opinion surveys are time consuming. In addition, customers do not always know what kind of services they would benefit from. For the empirical part of the study, a business area was identified where traditional ways of measuring value-in-use are difficult or in some cases even not possible. This business area is safety telephone services. These services are most often used by the elderly. The way to define value-in-use here was to assess how well the services offered met customer expectations. Comparing the services customers asked for and the services provided to them indicated whether customer expectations were met. This study showed that customers had their ideas concerning the contents of the services but many times the services provided did not meet these expectations. Organisational efficiency aspirations can decrease customers’ value-in-use. This study found a solution, in which increasing organisational efficiency would go hand-in-hand with increasing customers’ value-in-use; the result being that the organisations’ needs and the service users’ expectations were in line. Value creation for customers produced organisational efficiency and thus increased productivity. In this study, customer expectations were observed by means of wellness technology. With the help of modern technology, customer expectations can be followed quickly and easily and customers can co-create with the organisation. This type of an approach could be useful even in the development of other services for other ages and in different contexts. If a service organisation decreases the number of personnel and, at the same time, tries to offer services to the same or a larger clientele, customers easily notice the change, which is often negative. To avoid harmful decrease in value-in-use, limitations to the aspiration of efficiency should be implemented – one of such is that the organisation is required to meet certain quality standards defined by experts. The aim is to secure that, as a result of efficiency aspirations in the organisation, the quality of the service offerings does not diminish below mutually agreed standards. Traditionally, when productivity in services has been estimated, organisational efficiency has not been combined with both customer expectations and an expert assessment of quality. This study contributes with novel thinking entitled ‘Relationship Management of the Elderly’. This study handles productivity, expert defined quality and value-in-use in an organisational context, which is practically untouched in previous research studies.

Mapping the Value Network Potential in Cross-sector Collaboration: Case welfare Services for Elderly in Finland

Value network has been studied greatly in the academic research, but a tool for value network mapping is missing. The objective of this study was to design a tool (process) for value network mapping in cross-sector collaboration. Furthermore, the study addressed a future perspective of collaboration, aiming to map the value network potential. During the study was investigated and pondered how to get the full potential of collaboration, by creating new value in collaboration process. These actions are parts of mapping process proposed in the study. The implementation and testing of the mapping process were realized through a case study of cross-sector collaboration in welfare services for elderly in the Eastern Finland. Key representatives in elderly care from public, private and third sectors were interviewed and a workshop with experts from every sector was also conducted in this regard. The value network mapping process designed in this study consists of specific steps that help managers and experts to understand how to get a complex value network map and how to enhance it. Furthermore, it make easier the understanding of how new value can be created in collaboration process. The map can be used in order to motivate participants to be engaged with responsibility in collaboration and to be fully committed in their interactions. It can be also used as a motivator tool for those organizations that intend to engage in collaboration process. Additionally, value network map is a starting point in many value network analyses. Furthermore, the enhanced value network map can be used as a performance measurement tool in cross-sector collaboration.

Mobile clinics in public health care: Integrated service offerings for rural elderly

This research is an analysis of the value and content of local service offerings that enable longer periods of living at home for elderly people. Mobile health care and new distribution services have provided an interesting solution in this context. The research aim to shed light on the research question, ‘How do we bundle services based on different customer needs?’ A research process consisting of three main phases was applied for this purpose. During this process, elderly customers were segmented, the importance of services was rated and service offerings were defined. Value creation and service offering provides theoretical framework for the research. The target group is South Karelia’s 60 to 90-year old individuals and the data has been acquired via a postal questionnaire. Research has been conducted as exploratory research utilizing the methods of quantitative and social network analysis. The main results of the report are identified customer segments and service packages that fits to the segments’ needs. The results indicate the needs of customers and the results are additionally analysed from the producer’s point of view. In addition to the empirical results, the used theory framework has been developed further in order for the service-related theories to be seen from the customer’s point of view and not just from the producer’s point of view.

Outcome of human papillomavirus infection among men in the Finnish Family HPV Study

Ihmisen papilloomaviruksen taudinkuva suomalaisperheiden seurantatutkimuksen mieskohortissa Tieto ihmisen papilloomaviruksen (HPV) yhteydestä eri anatomisten alueiden sairauksien syntyyn on lisännyt mielenkiintoa miehen papilloomavirustulehduksen taudinkulun selvittämiseksi. Tämä väitöskirjatyö on osa suomalaista seurantatutkimusta, jossa tutkitaan HPVinfektioiden tartuntareittejä 329 perheessä. Väitöstyössä keskitytään tutkimukseen osallistuneiden 131 miehen aineistoon. Suun limakalvonäytteet otettiin seitsemässä aikapisteessä. Lisäksi otettiin sukuelinalueen näytteet kahdella seurantakäynnillä. Riskitekijöitä kartoittava kyselytutkimus teetettiin tutkimuksen alkutilanteessa sekä viimeisellä seurantakäynnillä. Oireettomat HPV infektiot olivat alkutilanteessa yleisiä molemmilla sukupuolilla (miesten suu 18,3 % ja sukuelinalue 35,9 %, naisten suu 17,2 % ja kohdunsuu 18,8 %), mutta HPV:n genotyyppien vastaavuus partnerien välillä oli vähäinen. Naisen, mutta ei miehen, seksuaalinen riskikäyttäytyminen oli yhteydessä pariskunnan HPV tyyppien vastaavuuteen. Partnerin ja siviilisäädyn vaihtaminen lisäsivät miehen riskiä saada uusia HPV infektioita. Miehen suun limakalvonäytteistä löytyi kaikkiaan 17 eri HPV tyyppiä. Suun HPV-tulehduksen esiintyvyys vaihteli eri aikapisteissä 15 %:sta 31 %:iin. Uusien HPV tulehdusten ilmaantumisaika vaihteli 3,9 ja 25,7 kuukauden välillä. Suun HPV infektio parani valtaosalla miehistä. Suun krooninen HPV-infektio todettiin 14 %:lla miehistä. Näiden infektioiden keskimääräinen kesto vaihteli 6.0:sta 30.7:ään kuukauteen. Tupakointi lisäsi korkean riskin HPV tyyppien aiheuttamien suun kroonisten infektioiden riskiä, kun taas aikaisemmin sairastetut sukuelinten kondyloomat suojasivat siltä. Tuloksemme osoittavat, että miehen oireeton HPV tulehdus on yleinen suussa ja sukuelinten alueella. Vakaa parisuhde suojaa uusilta HPV tulehduksilta. Tupakoinnilla on keskeinen merkitys suun HPV-infektion kroonistumisessa.

"Visst är det väldigt jobbigt, men det är också bra." : en studie om hur närståendevårdare upplever positiva och negativa effekter av närståendevård

Avhandlingens syfte är att studera hur närståendevårdare upplever positiva och negativa effekter av närståendevård, samt hur de upplever faktorer som kan inverka på deras livstillfredsställelse. Den empiriska analysens första frågeställning gäller ifall närståendevårdarna upplever både positiva och negativa effekter av närståendevård, och i så fall vilka positiva och negativa effekter som närståendevårdaren upplever. Den andra frågeställningen gäller vilka upplevelser och erfarenheter närståendevårdarna har i fråga om faktorer som kan påverka deras livstillfredsställelse. En kvalitativ metod har använts för att genomföra studien. För att undersöka respondenternas subjektiva tankar kring forskningsfrågan har nio temaintervjuer genomförts. Det insamlade materialet har analyserats med kvalitativ innehållsanalys. Respondenterna är svenskspråkiga närståendevårdare i åldern 45–80 år bosatta i Jakobstad, Pedersöre, Larsmo eller Nykarleby, som vårdar en annan vuxen person som inte är deras barn. Analysen visar att närståendevårdarna upplever både negativa och positiva effekter av närståendevård. Närståendevårdarna upplever negativa och positiva effekter i varierande utsträckning. Närståendevårdarna använder sig av både problemorienterad och emotionellt och kognitivt inriktad coping. Närståendevårdarnas psykiska och fysiska hälsa påverkas av närståendevårdararbetet. Vårdtagarens hälsa inverkar på närståendevårdarnas upplevelse av närståendevården. Närståendevårdarna upplever att de är bundna till vårdtagaren eller vårdplatsen, och kan ha svårt att hitta sammanhängande egen tid. Närståendevårdarna upplever att de får socialt stöd från närstående, tredje sektorn, samhället, andra närståendevårdare och privata sektorn. Närståendevårdarna upplever att de får socialt stöd, men det sociala stödet är ibland inte tillräckligt och respondenterna upplever därför också brist på socialt stöd.

Los newagers: el efecto colibrí. Artífices de menús especializados, tejedores de circuitos en la red, y polinizadores de culturas híbridas

En este artículo se describe la trayectoria de búsqueda espiritual de un agente nodal en la red espiritual alternativa comúnmente conocida como New Age para atender el impacto de su trayectoria en la hibridación de una espiritualidad neoindia. Se proponen tres procesos a tenerse en cuenta para una metodología del estudio del impacto de hibridación cultural que genera el New Age: 1) Su condición de diseñador de menús creyentes individualizados hechos con retazos de distintas tradiciones religiosas (Champion y Hervieu-Lèger 1990); 2) su agencia como “agente nodal” para tejer articulaciones, alianzas y conexiones en la red: entre otros agentes nodos, entre diversos circuitos y otros campos sociales especializados; y 3) su competencia de “polinizador” (Soares 2009) de culturas y religiones. El argumento de este trabajo destaca que los buscadores espirituales en su andar no sólo recogen fragmentos culturales de distintas tradiciones para armar menús personalizados de creencias, sino que además son transmisores de significados que contribuyen a hibridar las culturas por donde van pasando. Muchas de las cuales coinciden con comunidades étnicas valoradas por su relación con la naturaleza, su ancestralidad y su exotismo a los ojos de los occidentales.

Cardiorespiratory adaptations induced by aerobic training in middle-aged men: the importance of a decrease in sympathetic stimulation for the contribution of dynamic exercise tachycardia

We investigated the effects of aerobic training on the efferent autonomic control of heart rate (HR) during dynamic exercise in middle-aged men, eight of whom underwent exercise training (T) while the other seven continued their sedentary (S) life style. The training was conducted over 10 months (three 1-h sessions/week on a field track at 70-85% of the peak HR). The contribution of sympathetic and parasympathetic exercise tachycardia was determined in terms of differences in the time constant effects on the HR response obtained using a discontinuous protocol (4-min tests at 25, 50, 100 and 125 watts on a cycle ergometer), and a continuous protocol (25 watts/min until exhaustion) allowed the quantification of the parameters (anaerobic threshold, VO2 AT; peak O2 uptake, VO2 peak; power peak) that reflect oxygen transport. The results obtained for the S and the T groups were: 1) a smaller resting HR in T (66 beats/min) when compared to S (84 beats/min); 2) during exercise, a small increase in the fast tachycardia (D0-10 s) related to vagal withdrawal (P<0.05, only at 25 watts) was observed in T at all powers; at middle and higher powers a significant decrease (P<0.05 at 50, 100 and 125 watts) in the slow tachycardia (D1-4 min) related to a sympathetic-dependent mechanism was observed in T; 3) the VO2 AT (S = 1.06 and T = 1.33 l/min) and VO2 peak (S = 1.97 and T = 2.47 l/min) were higher in T (P<0.05). These results demonstrate that aerobic training can induce significant physiological adaptations in middle-aged men, mainly expressed as a decrease in the sympathetic effects on heart rate associated with an increase in oxygen transport during dynamic exercise.

Low levels of sex hormone-binding globulin and hyperproinsulinemia as markers of increased pancreatic ß-cell demand in men

Low levels of sex hormone-binding globulin (SHBG) are considered to be an indirect index of hyperinsulinemia, predicting the later onset of diabetes mellitus type 2. In the insulin resistance state and in the presence of an increased pancreatic ß-cell demand (e.g. obesity) both absolute and relative increases in proinsulin secretion occur. In the present study we investigated the correlation between SHBG and pancreatic ß-cell secretion in men with different body compositions. Eighteen young men (30.0 ± 2.4 years) with normal glucose tolerance and body mass indexes (BMI) ranging from 22.6 to 43.2 kg/m2 were submitted to an oral glucose tolerance test (75 g) and baseline and 120-min blood samples were used to determine insulin, proinsulin and C-peptide by specific immunoassays. Baseline SHBG values were significantly correlated with baseline insulin (r = -0.58, P<0.05), proinsulin (r = -0.47, P<0.05), C-peptide (r = -0.55, P<0.05) and also with proinsulin at 120 min after glucose load (r = -0.58, P<0.05). Stepwise regression analysis revealed that proinsulin values at 120 min were the strongest predictor of SHBG (r = -0.58, P<0.05). When subjects were divided into obese (BMI >28 kg/m2, N = 8) and nonobese (BMI £25 kg/m2, N = 10) groups, significantly lower levels of SHBG were found in the obese subjects. The obese group had significantly higher baseline proinsulin, C-peptide and 120-min proinsulin and insulin levels. For the first time using a specific assay for insulin determination, a strong inverse correlation between insulinemia and SHBG levels was confirmed. The finding of a strong negative correlation between SHBG levels and pancreatic ß-cell secretion, mainly for the 120-min post-glucose load proinsulin levels, reinforces the concept that low SHBG levels are a suitable marker of increased pancreatic ß-cell demand.
