RESUMO

All microorganisms like bacteria, viruses and fungi that reside within a host environment are considered a microbiome. The number of bacteria almost equal that of human cells, however, the genome of these bacteria may be almost 100 times larger than the human genome. Every aspect of the physiology and health can be influenced by the microbiome living in various parts of our body. Any imbalance in the microbiome composition or function is seen as dysbiosis. Different types of dysbiosis are seen and the corresponding symptoms depend on the site of microbial imbalance. The contribution of the intestinal and extra-intestinal microbiota to influence systemic activities is through interplay between different axes. Whole body dysbiosis is a complex process involving gut microbiome and non-gut related microbiome. It is still at the stage of infancy and has not yet been fully understood. Dysbiosis can be influenced by genetic factors, lifestyle habits, diet including ultra-processed foods and food additives, as well as medications. Dysbiosis has been associated with many systemic diseases and cannot be diagnosed through standard blood tests or investigations. Microbiota derived metabolites can be analyzed and can be useful in the management of dysbiosis. Whole body dysbiosis can be addressed by altering lifestyle factors, proper diet and microbial modulation. The effect of these interventions in humans depends on the beneficial microbiome alteration mostly based on animal studies with evolving evidence from human studies. There is tremendous potential for the human microbiome in the diagnosis, treatment, and prognosis of diseases, as well as, for the monitoring of health and disease in humans. Whole body system-based approach to the diagnosis of dysbiosis is better than a pure taxonomic approach. Whole body dysbiosis could be a new therapeutic target in the management of various health conditions.

RESUMO

Understanding noncardiovascular comorbidities and geriatric syndromes in elderly patients with heart failure (HF) is important as the average age of the population increases. Healthcare professionals need to consider these complex dynamics when managing older adults with HF, especially those older than 80. A number of small studies have described associations between HF and major geriatric domains. With information on patients' cognitive, functional decline, and ability to adhere to therapy, physicians can plan for individualized treatment goals and recommendations for these patients.

RESUMO

AIM: Mild cognitive impairment (MCI) is the prodromal phase of dementia. The objective of this study was to determine whether specific antihypertensives were associated with conversion from MCI to dementia. METHODS: In this retrospective study, a chart review was conducted on 335 older adults seen at the University of Alberta Hospital, Kaye Edmonton Seniors Clinic who were diagnosed with MCI. At the point of diagnosis, data was collected on demographic and lifestyle characteristics, measures of cognitive function, blood pressure measurements, use of antihypertensives, and other known or suspected risk factors for cognitive decline. Patients were followed for 5.5 years for dementia diagnoses. A logistic regression analysis was then conducted to determine the factors associated with conversion from MCI to dementia. RESULTS: Mean age (± standard deviation) of the study participants was 76.5 ± 7.3 years. Patients who converted from MCI to dementia were significantly older and were more likely to have a family history of dementia. After controlling for potential confounders including age, sex, Mini Mental Status Exam scores and family history of dementia, patients who were on beta-blockers (BBs) had a 57% reduction in the odds of converting to dementia (OR: 0.43, 95% CI: 0.23, 0.81). CONCLUSIONS: In this study, BB use was protective against conversion from MCI to dementia. Further studies are required to confirm the findings of our study and to elucidate the effect of BBs on cognitive decline.

RESUMO

Background: Subjects with mild cognitive impairment (MCI) can progress to dementia. Studies have shown that neuropsychological tests, biological or radiological markers individually or in combination have helped to determine the risk of conversion from MCI to dementia. These techniques are complex and expensive, and clinical risk factors were not considered in these studies. This study examined demographic, lifestyle and clinical factors including low body temperature that may play a role in the conversion of MCI to dementia in elderly patients. Methods: In this retrospective study, a chart review was conducted on patients aged 61 to 103 years who were seen at the University of Alberta Hospital. Information on onset of MCI and demographic, social, and lifestyle factors, family history of dementia and clinical factors, and current medications at baseline was collected from patient charts on an electronic database. The conversion from MCI to dementia within 5.5 years was also determined. Logistic regression analysis was conducted to identify the baseline factors associated with conversion from MCI to dementia. Results: The prevalence of MCI at baseline was 25.6% (335/1,330). During the 5.5 years follow-up period, 43% (143/335) of the subjects converted to dementia from MCI. The factors that were significantly associated with conversion from MCI to dementia were family history of dementia (odds ratio (OR): 2.78, 95% confidence interval (CI): 1.56 - 4.95, P = 0.001), Montreal cognitive assessment (MoCA) score (OR: 0.91, 95% CI: 0.85 - 0.97, P = 0.01), and low body temperature (below 36 °C) (OR: 10.01, 95% CI: 3.59 - 27.88, P < 0.001). Conclusion: In addition to family history of dementia and MoCA, low body temperature was shown to be associated with the conversion from MCI to dementia. This study would help clinicians to identify patients with MCI who are at highest risk of conversion to dementia.

RESUMO

BACKGROUND: Home blood pressure (BP) telemonitoring combined with case management leads to BP reductions in individuals with hypertension. However, its benefits are less clear in older (age ≥ 65 years) adults. METHODS: Twelve-month, open-label, randomized trial of community-dwelling older adults comparing the combination of home BP telemonitoring (HBPM) and pharmacist-led case management, vs. enhanced usual care with HBPM alone. The primary outcome was the proportion achieving systolic BP targets on 24-h ambulatory BP monitoring (ABPM). Changes in HBPM were also examined. Logistic and linear regressions were used for analyses, adjusted for baseline BP. RESULTS: Enrollment was stopped early due to coronavirus disease 2019. Participants randomized to intervention (n = 61) and control (n = 59) groups were mostly female (77%), with mean age 79.5 years. The adjusted odds ratio for ABPM BP target achievement was 1.48 (95% confidence interval 0.87-2.52, P = 0.15). At 12 months, the mean difference in BP changes between intervention and control groups was -1.6/-1.1 for ABPM (P-value 0.26 for systolic BP and 0.10 for diastolic BP), and -4.9/-3.1 for HBPM (P-value 0.04 for systolic BP and 0.01 for diastolic BP), favoring the intervention. Intervention group participants had hypotension (systolic BP < 110) more frequently (21% vs. 5%, P = 0.009), but no differences in orthostatic symptoms, syncope, non-mechanical falls, or emergency department visits. CONCLUSIONS: Home BP telemonitoring and pharmacist case management did not improve achievement of target range ambulatory BP, but did reduce home BP. It did not result in major adverse consequences.

RESUMO

INTRODUCTION: Advancements in medical and consumer-grade technologies have made it easier than ever to monitor a patient's heart rhythm and to diagnose arrhythmias. Octogenarians with symptomatic arrhythmias have unique management challenges due to their frailty, complex drug interactions, cognitive impairment, and competing comorbidities. The management decisions are further complicated by the lack of randomized evidence to guide treatment. AREAS COVERED: A comprehensive literature review was undertaken to outline various tachyarrhythmias and bradyarrhythmias and their management, the role of cardiac implantable electronic devices, cardiac ablations, and specific geriatric arrhythmia considerations as recommended in international guidelines. EXPERT OPINION: Atrial fibrillation (AF) is arguably the most important arrhythmia in the elderly and is associated with significant morbidity and mortality. Early diagnosis of AF, potentially with smart devices (wearables), has the potential to reduce the incidence of stroke, systemic emboli, and the risk of dementia. Bradyarrhythmias have a high incidence in the elderly as well, often requiring implantation of a permanent pacemaker. Leadless pacemakers implanted directly into the right ventricle are great options for gaining traction in elderly patients.

RESUMO

OBJECTIVE: To examine the association between income and cardiovascular disease (CVD) in community-dwelling older adults. METHODS: Of the 5795 Medicare-eligible community-dwelling older Americans aged 65-100 years in the Cardiovascular Health Study (CHS), 4518 (78%) were free of baseline CVD, defined as heart failure, acute myocardial infarction, stroke, or peripheral arterial disease. Of them, 1846 (41%) had lower income, defined as a total annual household income <$16,000. Using propensity scores for lower income, estimated for each of the 4518 participants, we assembled a matched cohort of 1078 pairs balanced on 42 baseline characteristics. Outcomes included centrally adjudicated incident CVD and mortality. RESULTS: Matched participants (n = 2156) had a mean age of 73 years, 63% were women, and 13% African American. During an overall follow-up of 23 years, incident CVD, all-cause mortality and the combined endpoint of incident CVD or mortality occurred in 1094 (51%), 1726 (80%) and 1867 (87%) individuals, respectively. Compared with the higher income group, hazard ratio (HR) for time to the first occurrence of incident CVD in the lower income group was 1.16 with a 95% confidence interval (CI) of 1.03 to 1.31. A lower income was also associated with a significantly higher risk of all-cause mortality (HR, 1.19; 95% CI, 1.08-1.30), and consequently a higher risk of the combined endpoint of incident CVD or death (HR, 1.20; 95% CI, 1.09-1.31). CONCLUSION: Among community-dwelling older Americans free of baseline CVD, an annual household income <$16,000 is independently associated with significantly higher risks of new-onset CVD and death.

RESUMO

Microbial therapeutics, which include gut biotics and fecal transplantation, are interventions designed to improve the gut microbiome. Gut biotics can be considered as the administration of direct microbial populations. The delivery of this can be done through live microbial flora, certain food like fiber, microbial products (metabolites and elements) obtained through the fermentation of food products, or as genetically engineered substances, that may have therapeutic benefit on different health disorders. Dietary intervention and pharmacological supplements with gut biotics aim at correcting disruption of the gut microbiota by repopulating with beneficial microorganism leading to decrease in gut permeability, inflammation, and alteration in metabolic activities, through a variety of mechanisms of action. Our understanding of the pharmacokinetics of microbial therapeutics has improved with in vitro models, sampling techniques in the gut, and tools for the reliable identification of gut biotics. Evidence from human studies points out that prebiotics, probiotics and synbiotics have the potential for treating and preventing mental health disorders, whereas with paraprobiotics, proteobiotics and postbiotics, the research is limited at this point. Some animal studies point out that gut biotics can be used with conventional treatments for a synergistic effect on mental health disorders. If future research shows that there is a possibility of synergistic effect of psychotropic medications with gut biotics, then a gut biotic or nutritional prescription can be given along with psychotropics. Even though the overall safety of gut biotics seems to be good, caution is needed to watch for any known and unknown side effects as well as the need for risk benefit analysis with certain vulnerable populations. Future research is needed before wide spread use of natural and genetically engineered gut biotics. Regulatory framework for gut biotics needs to be optimized. Holistic understanding of gut dysbiosis, along with life style factors, by health care providers is necessary for the better management of these conditions. In conclusion, microbial therapeutics are a new psychotherapeutic approach which offer some hope in certain conditions like dementia and depression. Future of microbial therapeutics will be driven by well-done randomized controlled trials and longitudinal research, as well as by replication studies in human subjects.

RESUMO

The gut microbiota (GM) plays a role in the development and progression of type 1 and type 2 diabetes mellitus (DM) and its complications. Gut dysbiosis contributes to the pathogenesis of DM. The GM has been shown to influence the efficacy of different antidiabetic medications. Intake of gut biotics, like prebiotics, probiotics and synbiotics, can improve the glucose control as well as the metabolic profile associated with DM. There is some preliminary evidence that it might even help with the cardiovascular, ophthalmic, nervous, and renal complications of DM and even contribute to the prevention of DM. More large-scale research studies are needed before wide spread use of gut biotics in clinical practice as an adjuvant therapy to the current management of DM.

RESUMO

INTRODUCTION: As individuals age, the prevalence of neurocognitive and mental health disorders increases. Current biomedical treatments do not completely address the management of these conditions. Despite new pharmacological therapy the challenges of managing these diseases remain.There is increasing evidence that the Gut Microbiome (GM) and microbial dysbiosis contribute to some of the more prevalent mental health and neurocognitive disorders, such as depression, anxiety, obsessive-compulsive disorder (OCD), post-traumatic stress disorder (PTSD), schizophrenia, bipolar disorder (BP), and dementia as well as the behavioural and psychological symptoms of dementia (BPSD) through the microbiota-gut-brain axis. Methodology: Scoping review about the effect of gut microbiota on neurocognitive and mental health disorders. RESULTS: This scoping review found there is an evolving evidence of the involvement of the gut microbiota in the pathophysiology of neurocognitive and mental health disorders. This manuscript also discusses how the psychotropics used to treat these conditions may have an antimicrobial effect on GM, and the potential for new strategies of management with probiotics and faecal transplantation. CONCLUSIONS: This understanding can open up the need for a gut related approach in these disorders as well as unlock the door for the role of gut related microbiota management. KEY MESSAGES Challenges of managing mental health conditions remain in spite of new pharmacological therapy. Gut dysbiosis is seen in various mental health conditions. Various psychotropic medications can have an influence on the gut microbiota by their antimicrobial effect.

RESUMO

OBJECTIVES: Atrial fibrillation (AF) is common in older adults and associated with increased risk of cardiovascular events including thromboembolism. However, less is known about its association with noncardiovascular events, especially geriatric syndromes and conditions such as dementia, depression, impaired physical function, polypharmacy, falls, and poor quality of life. This review aims to help healthcare professionals integrate the special needs of older adults into their management of AF. DESIGN: Nonsystematic review. A literature search on published articles on AF and geriatric syndromes and conditions was performed using the electronic databases MEDLINE, EMBASE and SCOPUS, and DARE until December 2017. Non-English articles were excluded. SETTINGS AND PARTICIPANTS: Older adults with and without AF from different settings. MEASURES: Various cognitive, mood, and functional measurements were used in these studies. In studies regarding polypharmacy, the Beers or PRISCUS criteria were used to identify inappropriate medications. In quality of life measurements studies, instruments like Medical Outcomes Study Short Form 36 and Atrial Fibrillation Quality of Life questionnaire were used. RESULTS: This literature review finds that AF has a substantial association with geriatric syndromes and conditions and that AF is a risk factor for the development of geriatric syndromes and conditions. Evidence is limited regarding the potential benefit of long-term treatment of AF in lowering the risk of developing geriatric syndromes and conditions. CONCLUSIONS/IMPLICATIONS: Considering the impact of AF on cardiovascular outcomes and geriatric syndromes and conditions in older adults, healthcare professionals need to consider these complex dynamics while managing AF in older adults. An individual approach to AF management is needed in older adults with multiple comorbidity and polypharmacy that may help lower the risk of disease-disease, disease-drug, and drug-drug interactions. Special consideration needs to be given to patients' cognitive and functional impairment and ability to adhere to therapy.

RESUMO

Prescribing medications safely and effectively in older adults is a complex process. This review discusses challenges with medication prescribing in older adults and outlines a holistic approach to medication management in older adults. Well-known challenges including the alterations in pharmacokinetics and pharmacodynamics that often occur with aging are discussed. Other classic concerns including polypharmacy, potentially inappropriate medication use, prescribing cascades, suboptimal prescribing, paradoxical harm and unintended consequences of medications, and drug interactions are reviewed. Newer approaches, including deprescribing, pharmacogenomics, and the future potential for senolytic therapy are also discussed. All healthcare providers should consider these challenges when prescribing medications in older adults. Choosing a drug that fits both a patient's pathophysiology and biology, avoiding drugs with significant side effects, titrating doses, and deprescribing are all critical in optimizing medication therapy.

RESUMO

INTRODUCTION: Cardiac rehabilitation program is an evidence-based intervention and established model of exercise delivery following myocardial infarction and heart failure. Although it forms an important part of recovery and helps to prevent future events and complications, there has been little focus on its potential cognitive benefits. Areas covered: Coronary artery disease and heart failure are common heart problems associated with significant morbidity and mortality, and cognitive decline is commonly seen in affected individuals. Cognitive impairment may influence patient self-management by reducing medication adherence, rendering patients unable to make lifestyle modifications and causing missed healthcare visits. Cognitive assessment in cardiac rehabilitation as an outcome measure has the potential to improve clinical, functional and behavioral domains as well as help to reduce gaps in the quality of care in these patients. Expert commentary: Limited evidence at present has shown that cardiac rehabilitation and exercise has potential in preventing cognitive decline. Cardiac prehabilitation, a rehabilitation-like program delivered before cardiac surgery, may also play a role in preventing postoperative cognitive dysfunction, but needs future research studies to support it.

RESUMO

BACKGROUND: Orthostatic hypotension (OH) is associated with falls and cardiovascular events. There is growing evidence that central blood pressure (CBP) is better than peripheral blood pressure (PBP) in predicting adverse outcomes. The objectives of this study were to assess 1) the prevalence of OH identified using PBP and CBP and the levels of agreement, 2) the respective associations between OH and falls and cardiovascular comorbidities, by PBP and CBP, and 3) the association of OH with arterial wall stiffness markers (augmentation pressure (AP) and augmentation index (AI)). METHODS: An observational case-control study of subjects aged 50 years and above was conducted at the University of Alberta Hospital inpatient wards and outpatient clinics. This study used a non-invasive technology called SphygmoCor to assess changes in CBP between lying, 1, 3 and 6 min of standing. AP and AI, which are markers of arterial wall stiffness, were also measured in this study. Dementia, significant psychological problems, and isolation precautions were exclusion criteria. Both PBP and CBP were measured with arm cuffs in lying and standing positions. OH was diagnosed using consensus criteria. RESULTS: Of the 71 participants recruited, mean age was 72.3 ±10.3 years, 52% were males, 32% had a history of falls and 72% had hypertension. OH occurred within 1, 3 or 6 min of standing (transient OH) in 31% by PBP and 27% by CBP (kappa = 0.56). OH persisted for all 6 min (persistent OH) in 16% by both PBP and CBP (kappa = 0.68). A significant relationship was observed between transient OH by CBP and baseline hypertension (P = 0.05) and dyslipidemia (P = 0.02). There was a significant difference in the mean AP between subjects with and without central persistent OH (P = 0.02), but not between subjects with and without peripheral persistent OH. The mean AI was not significantly different between subjects with or without central or peripheral persistent OH and between subjects with and without peripheral or central transient OH. CONCLUSION: Prevalence of OH was similar between PBP and CBP. However, there was only moderate agreement with OH identified by PBP and CBP indicating some inconsistencies across the sample in identifying OH.

RESUMO

BACKGROUND: Frailty is a state of vulnerability to diverse stressors. We assessed the impact of frailty on outcomes after discharge in older surgical patients. METHODS: We prospectively followed patients 65 years of age or older who underwent emergency abdominal surgery at either of 2 tertiary care centres and who needed assistance with fewer than 3 activities of daily living. Preadmission frailty was defined according to the Canadian Study of Health and Aging Clinical Frailty Scale as "well" (score 1 or 2), "vulnerable" (score 3 or 4) or "frail" (score 5 or 6). We assessed composite end points of 30-day and 6-month all-cause readmission or death by multivariable logistic regression. RESULTS: Of 308 patients (median age 75 [range 65-94] yr, median Clinical Frailty Score 3 [range 1-6]), 168 (54.5%) were classified as vulnerable and 68 (22.1%) as frail. Ten (4.2%) of those classified as vulnerable or frail received a geriatric consultation. At 30 days after discharge, the proportions of patients who were readmitted or had died were greater among vulnerable patients (n = 27 [16.1%]; adjusted odds ratio [OR] 4.60, 95% confidence interval [CI] 1.29-16.45) and frail patients (n = 12 [17.6%]; adjusted OR 4.51, 95% CI 1.13-17.94) than among patients who were well (n = 3 [4.2%]). By 6 months, the degree of frailty independently and dose-dependently predicted readmission or death: 56 (33.3%) of the vulnerable patients (adjusted OR 2.15, 95% CI 1.01-4.55) and 37 (54.4%) of the frail patients (adjusted OR 3.27, 95% CI 1.32-8.12) were readmitted or had died, compared with 11 (15.3%) of the patients who were well. INTERPRETATION: Vulnerability and frailty were prevalent in older patients undergoing surgery and unlikely to trigger specialized geriatric assessment, yet remained independently associated with greater risk of readmission for as long as 6 months after discharge. Therefore, the degree of frailty has important prognostic value for readmission. TRIAL REGISTRATION FOR PRIMARY STUDY: ClinicalTrials.gov, no. NCT02233153.

RESUMO

BACKGROUND: Isolated systolic hypertension and isolated diastolic hypotension are common in older adults and associated with a higher risk of incident heart failure (HF). However, little is known about the prevalence and impact of isolated diastolic hypertension in this population. METHODS: In the Cardiovascular Health Study (CHS), of the 5776 community-dwelling older adults ≥65years who had data on baseline systolic and diastolic blood pressure (SBP and DBP), 28 had isolated diastolic hypertension (DBP ≥90mmHg and SBP <140mmHg). From the 5748 without isolated diastolic hypertension, we excluded those with SBP ≥120mmHg (n=4451), DBP 80-89mmHg (n=20), DBP <60mmHg (n=425), normal BP taking anti-hypertensive medications (n=311), normal BP taking no anti-hypertensive medications but with history of hypertension (n=38), and baseline HF (n=5). The final cohort of 524 participants included 27 with isolated diastolic hypertension. RESULTS: Patients (n=524) had a mean (±SD) age of 71 (±5) years, 58% were women and 9% African American. There were no significant between-group age or sex differences; 37% of those with isolated diastolic hypertension (versus 7% without) were African American. Incident HF occurred in 19% and 7% of participants with and without isolated diastolic hypertension, respectively (multivariable-adjusted hazard ratio {HR}, 4.65; 95% confidence interval {CI}, 1.09-19.90; p=0.038). There was a trend toward higher cardiovascular mortality (HR, 4.59; 95% CI, 0.92-23.88; p=0.063). CONCLUSION: Among community-dwelling older adults, isolated diastolic hypertension is rare and is associated with higher risk for incident HF and cardiovascular mortality.

RESUMO

BACKGROUND: Isolated systolic hypertension (ISH) is common in older adults and is a risk factor for incident heart failure (HF). We examined the association of systolic-diastolic hypertension (SDH) with incident HF and other outcomes in older adults. METHODS: In the Cardiovascular Health Study (CHS), 5776 community-dwelling adults≥65years had data on baseline systolic and diastolic blood pressure (SBP and DBP). We excluded those with DBP<60mmHg (n=821), DBP≥90 and SBP<140mmHg (n=28), normal BP, taking anti-hypertensive drugs (n=1138), normal BP, not taking anti-hypertensive drugs, history of hypertension (n=193), and baseline HF (n=101). Of the remaining 3495, 1838 had ISH (SBP≥140 and DBP<90mmHg) and 240 had SDH (SBP≥140 and DBP≥90mmHg). The main outcome was centrally-adjudicated incident HF over 13years of follow-up. RESULTS: Participants had a mean (±SD) age of 73 (±6)years, 57% were women, and 16% African American. Incident HF occurred in 25%, 22% and 11% of participants with ISH, SDH and no hypertension, respectively. Compared to no hypertension, multivariable-adjusted hazard ratios (HR) and 95% confidence intervals (CI) for incident HF associated with ISH and SDH were 1.86 (1.51-2.30) and 1.73 (1.23-2.42), respectively. Cardiovascular mortality occurred in 22%, 24% and 9% of those with ISH, SDH and no hypertension, respectively with respective multivariable-adjusted HRs (95% CIs) of 1.88 (1.49-2.37) and 2.30 (1.64-3.24). CONCLUSION: Among older adults with hypertension, both SDH and ISH have similar associations with incident HF and cardiovascular mortality.

RESUMO

INTRODUCTION: This study on mild cognitive impairment (MCI) in heart failure (HF) compares the utility of Montreal Cognitive Assessment (MoCA) to the Mini-Mental Status Exam (MMSE) for diagnosing MCI in a HF population when compared to the golden standard European Consortium Criteria (ECC). METHODS: Participants were recruited from the Alberta HEART study at the Mazankowski Alberta Heart Institute in Edmonton and St. Mary's hospital in Camrose. This study enrolled 53 community adults aged>50years: 33 HF and 20 controls. Participants were assessed using both the MMSE and MoCA for MCI. MCI was diagnosed using the golden standard, European Consortium Criteria. Sensitivity and specificity analysis, positive and negative predictive values, likelihood ratios and kappa statistic were calculated. RESULTS: The mean age was 72.8years (SD 8.4), 60.4% were females and 34% had underlying ischemic heart disease. Overall, two thirds of patients (22/33, 66%) with HF had MCI. In comparison to European Consortium Criteria, the sensitivity and specificity of MoCA were 82% and 91% in identifying individuals with MCI, and MMSE were 9% and 91%, respectively. The positive and negative predictive values for MoCA were 95% and 71%, and for MMSE were 67% and 33%, respectively. Kappa statistics showed good agreement between MoCA and consortium criteria (kappa=0.68) and a low agreement between MMSE and consortium criteria (kappa=0.07). CONCLUSION: Cognitive dysfunction is common in patients with HF. Overall, the MoCA seems to be a better screening tool than MMSE for MCI in HF patients.
