RESUMO

BACKGROUND: Managing metastatic castration-resistant prostate cancer (mCRPC) in men aged ≥ 75 is challenging due to limited data. Regardless of age, in real-world clinical practice, most mCRPC still derive from failure of androgen deprivation therapy (ADT) with or without docetaxel (D) for metastatic castration-sensitive prostate cancer (mCSPC). As abiraterone acetate plus prednisone (AA) and enzalutamide (Enza) are common first-line treatments for mCRPC. The impact of prior use of D for mCSPC on the efficacy and safety of AA or Enza in this older population remains unclear. METHODS: A cohort of patients aged ≥ 75 years starting AA or Enza as first-line therapy for mCRPC from January 2015 to April 2019 was identified from the registries of 10 institutions. Patients were categorized into 2 groups based on previous use of D for mCSPC. Primary endpoints were cancer-specific survival (CSS) from AA or Enza start, CSS from ADT onset, and safety. We used Kaplan-Meier method to estimate the endpoints distribution, including median values with 95% confidence intervals (95% CI). RESULTS: Of the 337 patients identified, 24 (7.1%) received ADT+D and 313 (92.9%) received ADT alone for mCSPC. Median follow-up from AA/Enza start was 18.8 months. Median CSS from ADT or AA/Enza was not significantly different between ADT+D and ADT alone cohorts (71.9 vs. 52.7 months, P = .97; 25.4 vs. 27.2 months, P = .89, respectively). No statistically significant difference in adverse events (AEs) of any grade rate (58.3% vs. 52.1%, respectively; P = .67) or grade ≥ 3 (12.5% vs. 15.7%, respectively; P = 1.0) was found between ADT+D and ADT alone cohorts. CONCLUSIONS: Despite the innate limitations of a retrospective design and relatively small size of the ADT+D cohort, this analysis suggests that elderly men receiving AA or Enza as first-line therapy for mCRPC have similar survival outcomes and tolerability, regardless of previous D for mCSPC.

RESUMO

Background: Cognitive decline and negative emotions are common in aging, especially decline in cold cognition which often co-occurred with depression in middle-aged and older adults. This study analyzed the interactions between cold cognition and depression in the middle-aged and elder populations using network analysis and explored the effects of grandparenting on the cold cognition-depression network. Methods: The data of 6,900 individuals (≥ 45 years) from the China Health and Retirement Longitudinal Study (CHARLS) were used. The Minimum Mental State Examination (MMSE) and the Epidemiology Research Center Depression Scale-10 (CESD-10) were used to assess cold cognition and depressive symptoms, respectively. Centrality indices and bridge centrality indices were used to identify central nodes and bridge nodes, respectively. Results: Network analysis showed that nodes "language ability" and "depressed mood" were more central nodes in the network of cold cognition and depression in all participants. Meantime, nodes "attention," "language ability" and "hopeless" were three key bridge nodes connecting cold cognition and depressive symptoms. Additionally, the global connectivity of the cold cognition and depression network was stronger in the non-grandparenting than the grandparenting. Conclusion: The findings shed a light on the complex interactions between cold cognition and depression in the middle-aged and elder populations. Decline in language ability and depressed mood can serve as predictors for the emergence of cold cognitive dysfunction and depression in individuals during aging. Attention, language ability and hopelessness are potential targets for psychosocial interventions. Furthermore, grandparenting is effective in alleviating cold cognitive dysfunction and depression that occur during individual aging.

RESUMO

Background: It has been demonstrated that elderly people's cognitive capacities can be improved with exercise, and short sleep is linked to cognitive decline. However, the impact of physical exercise on cognitive performance in seniors who do not get enough sleep is largely unknown. This makes it an intriguing subject to explore further. Methods: This study consisted of elders (over 60 years old) who participated throughout the National Health and Nutrition Examination Survey's 2011-2014 cycle (NHANES). Weighted linear regression model and restricted cubic splines analysis were performed to evaluate the association between physical exercise and cognitive function. In the end, 1,615 samples were scrutinized and the total number of weighted respondents was 28,607,569. Results: Results showed that in the Animal Fluency test and the Digit Symbol Substitution test, a positive association was found between physical exercise volume and scores in the fully adjusted model. A two-piecewise linear regression model was then applied to explore the threshold effect of exercise on cognitive performance. Before 960 and 800 MET-minutes/week, there were consistent positive relationship between exercise and scores of the Animal Fluency test [ß (95% CI): 0.233 (0.154, 0.312), p < 0.001] and Digit Symbol Substitution test [ß (95% CI): 0.555 (0.332, 0.778), p < 0.001], respectively. However, there was a saturation effect where physical exercise volume reached the two inflection points. Conclusion: According to our research, the benefit of exercise did not always expand with the exercise volume increment under the short-sleep condition, which challenged existing knowledge. The short-sleep elder group could maintain cognitive performance with no more than 800 MET-minutes/week of physical exercise. Verification of these findings requires further biological investigations.

RESUMO

OBJECTIVES: Relationship between lipid profile and periodontitis has been reported. However, the association between lipid parameters and edentulism is unclear. This study aimed to investigate the association between lipid profile and reported edentulism in the elder population using a national cohort. METHODS: A total of 3 100 participants aged 65 or above were enrolled in 2011 from China Health and Retirement Longitudinal Study, which was a national population-based survey. We used adjusted logistics models to investigate the relationship between lipid profile and reported edentulism before and after propensity score matching. RESULTS: The mean (SD) age was 71.96 (5.63) years, and 1 581 (51.0%) were men. There were 254 (8.2%) individuals reporting edentulism, and the low-density lipoprotein cholesterol (LDL-C) was significantly higher in the reported edentulism group, compared with the non-edentulism (122.48 vs. 116.91 mg/dl, P = 0.015). In the multivariable model, LDL-C was significantly associated with a higher odds of reported edentulism (adjusted OR [95% CI], 1.004 [1.001-1.008]). In the matched population, LDL-C, non high-density lipoprotein cholesterol, remnant cholesterol, total cholesterol and triglycerides were positively associated with reported edentulism, while HDL-C was negatively associated. CONCLUSIONS: Lipid profiles are probably associated with edentulism, indicating the interaction between oral health and metabolic status in the elder population.

RESUMO

BACKGROUND: Numerous studies have suggested that lifestyle-related factors are associated with mortality, however limited evidence is available for the Chinese elder population. METHODS: The data of this study was obtained from the Chinese Longitudinal Health Survey (CLHLS) during 2008 - 2018, lifestyle-related factors including body mass index (BMI), smoking, drinking, consumption of vegetables and fruits, physical activity and sleep duration were included as dependent variables in the analysis. A lifestyle risk score was created using six unhealthy behaviors: smoking, drinking, unhealthy weight, physical inactivity, not eat vegetables or fruits and short or prolonged sleep. The Kaplan-Meier curves were used to illustrate the cumulative effect of lifestyle factors on mortality and cox regression models were conducted to estimate the combined effects of lifestyle-related factors on total mortality. RESULTS: The results illustrated that low BMI, smoking, no fruit eating, and no physical inactivity were risk factors for total mortality. KM curves showed significant cumulative effect of unhealthy lifestyle factors on mortality. Compared with participants without any unhealthy factors, the hazard ratio (HR) for participants with six unhealthy factors was 1.335 (1.015,1.757) for all-cause mortality. CONCLUSIONS: This study demonstrated poor adherence to a healthy lifestyle may increase all-cause mortality and specific combinations of lifestyle related factors have different effects on mortality among Chinese elderly population.

RESUMO

BACKGROUND: A lower systolic blood pressure (SBP) target reduces major cardiovascular events and mortality from any cause of geriatric hypertension. However, the effect of different SBP targets on myocardial function remains unclear. This study aimed to determine changes in left ventricular (LV) strain in older hypertensive patients after 1 year of different SBP goals, and to evaluate its effects on myocardial mechanics in this population. METHODS: We studied 313 hypertensive adults aged 60 years or older after 1 year of the Systolic Blood Pressure Intervention Trial. They were divided into the intensive group (target SBP: 110-130 mmHg) and the standard group (target SBP: 130-150 mmHg). All participants underwent echocardiography within 1 week after enrollment and 1 year after participating in the study. Global longitudinal strain (GLS) of the LV (endocardial, middle, and epicardial layer: GLS-end, GLS-mid, and GLS-epi, respectively) and the improvement of GLS at 1 year (ΔGLS-end, ΔGLS-mid, and ΔGLS-epi) were measured. RESULTS: At 1 year, GLS-end in the intensive group was slightly improved compared with that before the trial (-23.78%±3.10% vs -22.58%±3.11%, P<0.05). The ΔGLS-end and ΔGLS-mid in the intensive group were higher than those in the standard group (1.20±0.23 vs 0.58±0.59% and 0.70±0.21 vs 0.52±0.17, P<0.05). Moreover, SBP at 1 year and an angiotensin II type 1 receptor antagonist were independent factors that affected ΔGLS-end (ß= -0.005, P=0.004; ß= 0.080, P<0.001, respectively). CONCLUSION: These trial results suggest that a lower SBP target can slightly improve myocardial function in older hypertensive patients at 1 year.

RESUMO

INTRODUCTION: Changing demographics have created substantial unmet needs for mental health and physical disability services for immigrant and racial/ethnic minority elders. Workforce shortages can be reduced by task-shifting to community health workers (CHWs) who speak the same language and share the culture of these elders. Yet, implementation of interventions offered by CHWs requires adaptations of content and delivery, ideally under clinical supervision. OBJECTIVE: To culturally adapt two evidence-based interventions, offered in community settings, to address mental health and physical disability prevention for diverse minority elders. METHODS: We followed the Castro-Barrera stepped model for cultural adaptation of two evidence-based interventions into one combined program of disability management and prevention delivered by CHWs. We used feedback from key stakeholders, including four clinical supervisors, 16 CHWs, 17 exercise trainers, and 153 participants, collected at three time points to further adapt the intervention to a diverse population of elders. RESULTS: Adaptations for administration by CHWs/exercise trainers included: systematization of supervision process, increased flexibility in sessions offered per participants' needs, inclusion of self-care content, modification of materials to better reflect elders' daily life experiences, and greater focus on patient engagement in care. Areas for additional adaptation included enhancing examples with culturally relevant metaphors, incorporating visual aids, and training CHWs in the importance of building trust. CONCLUSION: This study identifies key aspects of the cultural adaptation process that facilitates broader cultural sensitivity of service delivery by CHWs to diverse elders in community settings.

RESUMO

Health care is a pillar of modern society. This study focuses on the use of descriptive analytics to provide demographic and territorial insights that will be of strategic importance in planning subsequent projects meant to improve health care services. We especially focus on the assessment of the elder and disabled population health care needs in Barcelona, and evaluate to what extent the current health care infrastructure is successful in covering the demand of these fragile population segment. This work is developed around three main assessments in the municipality of Barcelona: the elder and disabled health care demand, the available health care services, and the relationship between demand and services, showing that territorial and demographic aspects are relevant in assessing the health needs of the population.

RESUMO

BACKGROUND: The aim of the current study is to assess the cross-sectional association of chronic non-communicable diseases (hypertension, diabetes mellitus, arthritis, and cerebrovascular) with depressive symptoms among older adults in China. METHODS: Data was obtained from the China Longitudinal Ageing Social Survey (CLASS) conducted in 2014. A total of 7505 participants were included. Depressive symptoms status was assessed by 9-item Center for Epidemiological Studies Depression Scale (CES-D) Associations between depressive symptoms and chronic diseases, adjusting for so, demographics and chronic diseases risk factors were assessed by using logistic regression model. RESULTS: We found negative associations between depressive symptoms and several socioeconomic factors, including education attainment and economic level. Widowed/divorced/ unmarried individuals are more likely to suffer from depressive symptoms. Hypertension (Odds ratio:1.29 [95%CI:1.16, 1.42]), diabetes (1.41 [95%CI:1.19,1.67]), arthritis (1.72 [1.52, 1.96]), and cerebrovascular disease (1.69 [1.41, 2.02]) were found to be associated with depressive symptoms. CONCLUSIONS: Most depressive symptoms cases were found to be significantly associated with chronic diseases. Our findings have provided evidence for understanding co-morbid depressive symptoms with chronic diseases, which could help clinicians to evaluate, diagnose and manage depression promptly.

RESUMO

OBJECTIVE: Hepatitis C virus (HCV) infection is a major public health problem and affects large populations all over the world. Serum anti-HCV level is a valuable marker to determine HCV infection. Anti-HCV testing has been recommended for high-risk population. The Center for Disease Control (CDC) and Prevention in the United States proposed a new high-risk population group - adults born between 1945-1965. Under this perspective, we designed a multicentre retrospective study to determine the seropositivity of anti-HCV among adults born between 1945 and 1965 and adults born after 1965 in Turkey. With the data collected, we aimed to determine whether there was a need for anti-HCV testing especially in people born between 1945 and 1965. METHODS: We requested data from ten different medical centres in ten different provinces. Each medical centre collected the anti-HCV test results of adult patients for five-year period between 2009 and 2014 from hospital records. RESULTS: A total of 974,449 anti-HCV test results were included in this study. When the seropositivity rates in the two groups of adults were compared, anti-HCV seropositivity rates were higher in nine medical centres out of ten. Anti-HCV seropositivity in adults born between 1945-1965 was significantly higher than in adults born after 1965 (p < 0.05). CONCLUSIONS: We determined that the anti-HCV seropositivity rate is significantly higher in adults born between 1945-1965 compared to the younger adults as indicated in the literature. According to data from this study together with the WHO and CDC suggestions, we believe that it is appropriate to offer anti-HCV serology testing for people over 50 years of age since the anti- HCV seroprevalence in this age group is relatively high.

RESUMO

PURPOSE: The incidence of hip fractures is increasing within the aging population. Our objective was to identify and quantify the risk factors and develop a predictive model for the in-hospital mortality among hip fracture patients older than 65 years. METHODS: This is a prospective study conducted on 331 hip fracture patients older than 65 years admitted to our hospital from 2011 to 2014. Patients' demographics, prehospitalization residential status, prefracture comorbidity data, anti-aggregant and anticoagulant medication, preoperative hemoglobin value, type of fractures, type of treatments, time to surgery, and complications were recorded. RESULTS: The average age was 83 years, 73% female, and 57% of them sustained a femoral neck fracture. In 62.8% of patients, the number of pre-fracture baseline comorbidities was ≥2. The in-hospital mortality rate was 11.4%. In multivariate analysis, age over 90 years, congestive heart failure, asthma, rheumatologic disease, lung cancer, and not taking antiaggregant medication were independently associated with in-hospital mortality. A formula and risk stratification scoring for predicting the risk for in-hospital mortality was developed. Risk-adjustment model based on these variables had acceptable accuracy for predicting in-hospital mortality (c-statistic 0.77). CONCLUSION: Advanced age, and five prefracture comorbidities have a strong association with in-hospital mortality in a hip fracture patient older than 65 years old. Our predictive model was specifically designed for the old hip fracture population. It has an accuracy similar to other risk models. The specificity, positive predictive value, and negative predictive value are high. In addition, it could discriminate a high risk patient from a low risk patient for in-hospital mortality.

RESUMO

OBJECTIVES: To investigate the association between serum uric acid level and the presence and progression of carotid atherosclerosis in Chinese individuals aged 75 years or older. DESIGN: Case-control study. SETTING: In a teaching hospital. PARTICIPANTS: Five hundred and sixty-four elderlies (75 years or above) who underwent general health screening in our hospital were enrolled. MEASUREMENTS: The detailed carotid ultrasound results, physical examination information, medical history, and laboratory test results including serum uric acid level were recorded, these data were used to analyze the relationship between serum uric acid level and carotid atherosclerosis. Then, subjects who underwent the second carotid ultrasound 1.5-2 years later were further identified to analyzed the relationship between serum uric acid and the progression of carotid atherosclerosis. RESULTS: A total of 564 subjects were included, carotid plaque was found in 482 (85.5%) individuals. Logistic regression showed that subjects with elevated serum uric acid (expressed per 1 standard deviation change) had significantly higher incidence of carotid plaque (odds ratio, 1.37; 95% confidence interval, 1.07-1.75; P= 0.012) after controlling for other factors. A total of 236 subjects underwent the follow-up carotid ultrasound. Linear regression showed that serum uric acid level (expressed per 1 standard deviation change; 1 standard deviation = 95.5 µmol/L) was significantly associated with percentage of change of plaque score (P = 0.008). Multivariable linear regression showed that 1 standard deviation increase in serum uric acid levels was expected to increase 0.448% of plaque score (P = 0.023). CONCLUSION: The elevated serum uric acid level may be independently and significantly associated with the presence and progression of carotid atherosclerosis in Chinese individuals aged 75 years or older.

RESUMO

PURPOSE: Report on the safety, efficiency and refractive outcomes of LASIK surgery in patients aged 65 or older. METHODS: This study includes a case series of patients ≥65 years that underwent corneal refractive surgery during the period June 2010 to June 2015 at Hospital Zambrano Hellion, Monterrey, Mexico. Inclusion criteria were normal topography, central corneal thickness >500 µm, preoperative manifest refraction spherical equivalent (MRSE) up to -8.5 D and +6.0 D, cylinder up to -6.0 D, CDVA of 20/25 or better and with no other ocular pathology. RESULTS: A total of 44 eyes (24 patients) were included. Mean age was 67.2 ± 2.1 years (range 65-80), with mean follow-up of 12.2 ± 1.3 months. Conventional LASIK was performed in 20 patients (group 1, 36 eyes) to improve UDVA (10 eyes myopic LASIK and 26 eyes hyperopic LASIK) and presbyopic LASIK (monovision) in 4 patients (group 2, 8 eyes) to restore near-vision performance. Preoperative MRSE group 1 was myopic: -2.79 ± 1.88 D; hyperopic +2.19 ± 1.88 D; and +2.10 ± 0.87 D in group 2. Preoperative UDVA in group 1 was 0.67 ± 0.30 LogMAR; 0.46 ± 0.18 LogMAR; and Jaeger ≥4 in 90% in group 2. Postoperative MRSE: -0.29 ± 0.86 D (myopic LASIK) (p < 0.001), +0.34 ± 0.62 D (hyperopic LASIK) (p < 0.001) and -1.25 ± 0.59 D (non-dominant eye) in presbyopic LASIK. Postoperative UDVA in myopic LASIK was 0.15 ± 0.30 (p = 0.001) and 0.11 ± 0.11 (p < 0.001) for hyperopic LASIK. In group 2, binocular UDVA was 0.16 ± 0.17 (p = 0.12) and UNVA was ≥J2 in 100% of the patients. CONCLUSION: Even though elder patients may present greater LASIK restrictions due to lens and other ocular age-related changes, patients ≥65 years that were candidates for conventional and presbyopic LASIK showed satisfactory and safe refractive and visual outcomes.

RESUMO

Residents living in fluorosis areas generally experienced long-term exposure to excessive fluoride in drinking water. The adverse effects of high fluoride levels on the nervous system have been studied; however, the effect of fluoride exposure on cognitive functions of elderly people in fluorosis areas is rarely reported. This study was aimed to find out the potential risk factors of cognitive impairment among elderly people who lived in fluorosis areas of China. A total of 511 subjects, aged 60 years or above, were investigated in fluorosis areas of Heilongjiang Province, Inner Mongolia Autonomous Region, Qinghai Province, and Xinjiang Uygur Autonomous Region. The Mini-Mental State Examination (MMSE) was used to examine cognitive functions of the study subjects. Based on the MMSE scores, the study subjects were divided into normal group and cognitive impairment group that consisted of mild, moderate, and severe groups. Multivariable logistic regression showed that a higher risk of cognitive impairment was associated with increased age and decreased education levels. Multiple linear regression analysis revealed that MMSE scores were negatively associated with serum homocysteine (Hcy) levels. However, both urinary fluoride and serum Hcy levels in the normal group were not the lowest among the four groups. Spearman's correlation analysis showed that urinary fluoride levels were positively correlated with serum Hcy (r s = 0.209, P < 0.01). Our study suggests that people with cognitive impairment in fluorosis areas have elevated serum Hcy levels, which was positively correlated with urinary fluoride concentrations. A certain low dose of fluoride intake may play a potential protective rather than harmful role in cognitive functions; however, high fluoride exposure is a potential risk factor for cognitive impairment.

RESUMO

Objective: To investigate the relationship between long-, short-term systolic blood pressure variability (SBPV) and renal damage in elder population. Methods: Our research was conducted in the 3rd physical examination of healthy population from Kailuan group by cohort study. Cluster sampling was used by 25% ratio in subjects≥60 years of age to monitor their 24-hour ambulatory blood pressure and finally, 2464/3064 participants with inclusion criteria were recruited. SBPV indexes as standard deviation of systolic blood pressure (SSD), variability independent of the mean (VIM), maximum-minimum difference (MMD) and average real variability (ARV) were examined; renal damage indexes as estimated glomerular filtration rate (eGFR) and microalbuminuria (ALBU) were detected. Relationships between different long-term, short-term SBPV indexes and eGFR, ALBU were studied by multi-liner regression analysis. Results:①The mean age of 2464 participants was (67.41 ± 6.05) years including 1667 (67.7%) male and 797 (32.3%) female.②Multi-liner regression analysis indicated that different long-term SBPV indexes were not related to eGFR and ALBU; 24h SBPV in all 4 indexes and day-time SSD, MMD, ARV were negatively related to eGFR; 24h ARV and day-time MMD, ARV were positively related to ALBU; night-time SBPV indexes were not related to eGFR and ALBU.Conclusion: Different short-term SBPV indexes were, at certain point related to eGFR and ALBU
