- The aggregation of fibrils of hyperphosphorylated and C-terminally truncated microtubule-associated tau protein characterizes 80% of all dementia disorders, the most common neurodegenerative disorders. These so-called tauopathies are hitherto not curable and their diagnosis, especially at early disease stages, has traditionally proven difficult. A keystone in the diagnosis of tauopathies was the development of methods to assess levels of tau protein in vivo in cerebrospinal fluid, which has significantly improved our knowledge about these conditions. Tau proteins have also been measured in blood, but the importance of tau-related changes in blood is still unclear. The recent addition of positron emission tomography ligands to visualize, map and quantify tau pathology has further contributed with information about the temporal and spatial characteristics of tau accumulation in the living brain. Together, the measurement of tau with fluid biomarkers and positron emission tomography constitutes the basis for a highly active field of research. This review describes the current state of biomarkers for tau biomarkers derived from neuroimaging and from the analysis of bodily fluids and their roles in the detection, diagnosis and prognosis of tau-associated neurodegenerative disorders, as well as their associations with neuropathological findings, and aims to provide a perspective on how these biomarkers might be employed prospectively in research and clinical settings.

Forskningsöversikt (refereegranskat)abstract
- Background: The aim of this study was to explore trends in treatment with antipsychotic medication in Swedish dementia care in nursing homes as reported in the most recent empirical studies on the topic, and to relate these trends to directives from the national authorities. Methods: The study included two scoping review studies based on searches of electronic databases as well as the Swedish directives in the field. Results: During the past decade, directives have been developed for antipsychotic medication in Sweden. These directives were generic at first, but have become increasingly specific and restrictive with time. The scoping review showed that treatment with antipsychotic drugs varied between 6% and 38%, and was higher in younger older persons and in those with moderate cognitive impairment and living in nursing homes for people with dementia. A decreasing trend in antipsychotic use has been seen over the last 15 years. Conclusions: Directives from the authorities in Sweden may have had an impact on treatment with antipsychotic medication for people with dementia. Treatment with antipsychotic medication has decreased, while treatment with combinations of psychotropic medications is common. National directives may possibly be even more effective, if applied in combination with systematic follow-ups.

Forskningsöversikt (refereegranskat)abstract
- Women with chronic HIV infection (WWH) living in the United States, experience a disproportionately high rate of obesity compared to uninfected populations. Both overweight and obesity, particularly central obesity, are major contributors to insulin resistance, hypertension, and dyslipidemia—the major components of metabolic syndromes, including type 2 diabetes, and leading to increased cardiovascular risk, including coronary heart disease, and cerebrovascular diseases. Notably, declining physical performance and frailty co-occur with vascular morbidities as well as changes in bone. These factors tend to exacerbate each other and accelerate the aging trajectory, leading to poorer quality of life, cognitive impairments, dementia, and eventually, death. In WWH, persistent HIV infection, sustained treatment for HIV infection, and concomitant obesity, may accelerate aging-related morbidities and poorer aging outcomes. Furthermore, health disparities factors common among some WWH, are independently associated with obesity and higher vascular risk. The purpose of this review is to describe the constellation of obesity, cardio- and cerebrovascular diseases, bone health and frailty among aging WWH, a 21st century emergence.

- Introduction: Race is an important health determinant and should adequately be considered in research and drug development protocols targeting Alzheimer's disease (AD).Methods: A systematic review of available randomized controlled trials (RCTs) on the currently marketed treatments for AD was conducted with the aim of 1) documenting the reporting of race, and 2) exploring the impact of race on the efficacy and safety/tolerability of the considered medications.Results: Overall, 59.2% of the 49 retained RCTs reported information concerning the race of participants. Only a striking minority of enrolled patients was constituted of blacks and Hispanics. None on the retained studies reported results on the efficacy and safety/tolerability of the tested treatment separately for racial groups nor performed sensitivity analyses accounting for the race of participants.Discussion: Race has insufficiently been reported in previous interventional studies on AD. Its potential association with the effectiveness and safety/tolerability of the tested medications has completely been neglected.

- OBJECTIVETo examine the dose-response associations between accelerometer assessed total physical activity, different intensities of physical activity, and sedentary time and all cause mortality.DESIGNSystematic review and harmonised meta-analysis.DATA SOURCESPubMed, PsycINFO, Embase, Web of Science, Sport Discus from inception to 31 July 2018.ELIGIBILITY CRITERIAProspective cohort studies assessing physical activity and sedentary time by accelerometry and associations with all cause mortality and reported effect estimates as hazard ratios, odds ratios, or relative risks with 95% confidence intervals.DATA EXTRACTION AND ANALYSISGuidelines for meta-analyses and systematic reviews for observational studies and PRISMA guidelines were followed. Two authors independently screened the titles and abstracts. One author performed a full text review and another extracted the data. Two authors independently assessed the risk of bias. Individual level participant data were harmonised and analysed at study level. Data on physical activity were categorised by quarters at study level, and study specific associations with all cause mortality were analysed using Cox proportional hazards regression analyses. Study specific results were summarised using random effects meta-analysis.MAIN OUTCOME MEASUREAll cause mortality.RESULTS39 studies were retrieved for full text review; 10 were eligible for inclusion, three were excluded owing to harmonisation challenges (eg, wrist placement of the accelerometer), and one study did not participate. Two additional studies with unpublished mortality data were also included. Thus, individual level data from eight studies (n=36 383; mean age 62.6 years; 72.8% women), with median follow-up of 5.8 years (range 3.0-14.5 years) and 2149 (5.9%) deaths were analysed. Any physical activity, regardless of intensity, was associated with lower risk of mortality, with a non-linear dose-response. Hazards ratios for mortality were 1.00 (referent) in the first quarter (least active), 0.48 (95% confidence interval 0.43 to 0.54) in the second quarter, 0.34 (0.26 to 0.45) in the third quarter, and 0.27 (0.23 to 0.32) in the fourth quarter (most active). Corresponding hazards ratios for light physical activity were 1.00, 0.60 (0.54 to 0.68), 0.44 (0.38 to 0.51), and 0.38 (0.28 to 0.51), and for moderate-to-vigorous physical activity were 1.00, 0.64 (0.55 to 0.74), 0.55 (0.40 to 0.74), and 0.52 (0.43 to 0.61). For sedentary time, hazards ratios were 1.00 (referent; least sedentary), 1.28 (1.09 to 1.51), 1.71 (1.36 to 2.15), and 2.63 (1.94 to 3.56).CONCLUSIONHigher levels of total physical activity, at any intensity, and less time spent sedentary, are associated with substantially reduced risk for premature mortality, with evidence of a non-linear dose-response pattern in middle aged and older adults.

- Background: With worldwide population aging, increasing numbers of people need hospital care. Evidence suggests comprehensive geriatric assessment (CGA) is superior to usual care.Objective: To summarize the evidence for the effects of CGA in frail and moderately frail patients compared with usual care in acute care settings.Data sources: CINAHL, PsycInfo, Cochrane Library, EMBASE, and PubMed were searched in October 2011, January 2013, and February 2015.Study eligibility: Randomized controlled trials.Participants: Older adults aged ≥ 65 years who were admitted to hospital with a complex condition, divided into frail and moderately frail groups.Intervention: CGA.Control: Usual care.Outcomes: Change in housing, personal activities of daily living (PADL), instrumental activities of daily living (IADL), readmission, cognitive function, depression, quality-of-life care-giver burden, and mortality.Study appraisal and synthesis: The grading of recommendations assessment development and evaluation (GRADE) system to assess the quality of evidence and PRISMA-guidelines for meta-analyses and reviews. Continuous data were presented as standardized mean differences and dichotomous data were presented as risk differences.Results: Twenty-nine articles based on 17 unique studies (6005 patients in total). CGA was categorized as CGA-ward or CGA-consult. In the frail group, CGA-ward was superior to usual care for change in housing, PADL, and depression. CGA-consult was superior to usual care for PADL and IADL in the moderately frail group.Conclusion: There was a stronger effect for frail older adults and CGA-ward compared with usual care. This highlights the importance of detecting frailty. However, the degree of evidence was limited.

The scientific evidence for a potential link between confusion and urinary tract infection in the elderly is still confusing - A systematic literature review
- 2019
-
Ingår i: BMC Geriatrics. - : Springer Science and Business Media LLC. - 1471-2318. ; 19, s. 1-15
-
Forskningsöversikt (refereegranskat)abstract
- Context: Non-specific symptoms in elderly patients such as confusion is often suspected to be caused by a urinary tract infection (UTI) and it continues to be the most common reason for suspecting a UTI despite many other plausible causes. This leads to significant over diagnosis of UTI, increased inappropriate antibiotic use and potentially harmful outcomes through misdiagnosis. This problem is particularly prevalent in nursing homes settings. Objective: Clarify the correlation between lower UTI or bacteriuria and concurrent confusion. Setting: Any care setting for elderly (hospital, community and long term care facility). Design: A systematic literature review Main And Secondary Outcome Measures: A review of the literature was conducted assessing the association between confusion and UTI in the elderly. PubMed, Scopus and PsychInfo were searched with the following terms: confusion, delirium, altered mental status, acute confusional state, urinary tract infection, urine infection, urinary infection and bacteriuria. Inclusion criteria and methods were specified in advance and documented in the protocol, which was published with PROSPERO (registration ID CRD42015025804). Quality assessment was conducted independently by two authors. Data was extracted using a standardised extraction tool and a qualitative synthesis of evidence was made. Results: 1702 original records were identified of which 22 were included in the final analysis. Following this review, it appears that insufficient evidence is available to accurately determine if UTI and confusion are associated. Conclusion: The potential link between UTI and non-specific symptoms in elderly patients remain confusing. More epidemiological studies are unlikely to resolve this problem. The next logical step to clarify this issue should be a randomized controlled trial comparing the effect of antibiotics versus placebo using validated criteria for both UTI and confusion.

- This is a brief summary of experiences from Finland related to Alzheimer's disease (AD) prevention research. The first signals that AD may have vascular modifiable risk factors came from studies on cardiovascular conditions and diabetes. Cardiovascular prevention projects such as North Karelia Project and WHO-MONICA in the 1970-1980s were focused on younger populations, which led to the idea of looking for risk factors as far back as middle age. Cardiovascular Risk Factors, Aging and Incidence of Dementia (CAIDE) is one of the few studies in the world focusing on late-life cognition with a large and representative population-based cohort, baseline examination at midlife, and follow-up time up to three decades. Since 1998, it has identified several modifiable risk factors for cognitive impairment/dementia, and produced the first risk score for estimating dementia risk based on midlife profiles. The CAIDE Dementia Risk Score has been used to select participants in the Finnish Geriatric Intervention Study to prevent cognitive impairment and disability (FINGER). FINGER is an ongoing multicenter RCT involving 1,200 participants aged 60-77 years, and testing the effects of a two-year multi-domain intervention targeting several risk factors simultaneously. It started in September 2009 and will be completed at the end of 2013. The FINGER study is at the forefront of international collaborative efforts to solve the clinical and public health problems of early identification of individuals at increased risk of late-life cognitive impairment, and of developing intervention strategies to prevent or delay the onset of cognitive impairment and dementia.

- Background: There has been a steady increase in the prescription of antidepressants for the elderly. This study comprises a systematic review of randomized, placebo-controlled trials of antidepressants for treatment of depressive disorder in people aged 65 years or more. Methods: PubMed, EMBASE, Cochrane Library, CINAL, and PsycINFO were searched until May 2016. Where appropriate, the results were synthesized in meta-analyses. Results: Twelve trials met the inclusion criteria. For patients with major depressive disorder, selective serotonin re-uptake inhibitors (SSRI) were not superior to placebo in achieving remission (OR: 0.79, 95% CI: 0.61-1.03) or response (OR=0.86, 95% CI: 0.51-1.10) after 8 weeks of treatment (three trials). However, maintenance treatment with SSRIs was superior to placebo in preventing relapse (OR: 0.22, 95% CI: 0.13-0.36; NNT=5, 95% CI: 3-6; two trials). Duloxetine was superior to placebo in achieving remission (OR: 1.78, 95% CI: 1.20-2.65; NNT=9, 95% CI: 6-20; three trials) and response (OR: 1.83, 95% CI: 1.96-4.08; two trials) in recurrent major depression after 8 weeks, but increased the risk of adverse events that can be problematic in the elderly. Limitations: The quality of evidence was generally low or moderate, emphasizing the uncertainty of the results. Study populations only partly covered the heterogeneous population of elderly with depressed mood, limiting the generalizability. Conclusion: The results underscore the importance of close monitoring of the effects of antidepressants in treatment of elderly patients with a depressive disorder. Methods for early detection of non-responders and effective treatment options for this group are needed.
